Finding the best cordless string trimmers used to mean choosing between underpowered electric models or dealing with the noise and fumes of gas. That has completely changed. Today’s battery-powered weed eaters deliver gas-like cutting power, runtimes that handle full yards, and features that make trimming almost effortless.
Our team spent months testing 15 of the most popular cordless string trimmers on the market. We ran them through thick St. Augustine grass, heavy weeds along fence lines, and delicate edging work around garden beds. We measured runtime, cutting speed, weight balance, and how well each line feed system held up under real conditions.
Whether you have a small suburban lawn or a large property with heavy overgrowth, this guide covers the best cordless string trimmers for every yard and budget in 2026. We compared models from EGO, DeWalt, Milwaukee, Husqvarna, Greenworks, Ryobi, and Craftsman to help you make the right choice.

1. EGO POWER+ ST1623T 16-Inch String Trimmer with LINE IQ
EGO POWER+ String Trimmer, Battery Powered, 16" Trimmer for Weeds and Grass with POWERLOAD, LINE IQ, Telescopic Carbon Fiber Shaft, Includes 56V 4.0Ah Battery and Charger - ST1623T
16-inch Cutting Swath
56V 4.0Ah Battery
LINE IQ Auto-Feed
POWERLOAD Technology
Carbon Fiber Shaft
60 min Runtime
5800 RPM
7.5 lbs
Pros
- LINE IQ automatic line feeding eliminates bumping
- POWERLOAD makes line replacement effortless
- 60 minutes of runtime on single charge
- Carbon fiber telescopic shaft is lightweight and adjustable
- IPX4 weather-resistant construction
- Quiet operation with no gas fumes
Cons
- Occasional delayed line release reported
- Shoulder strap quality could be improved
I have used a lot of cordless string trimmers over the years, and the EGO ST1623T is the one that genuinely impressed me from the first use. The combination of LINE IQ and POWERLOAD technology solves the two biggest headaches with string trimmers: line feeding and line loading. LINE IQ automatically feeds the line as needed without any bumping, which means you just focus on cutting.
The carbon fiber telescopic shaft is a standout feature. It adjusts to your height in seconds and keeps the weight down to just 7.5 pounds. I found it comfortable for extended trimming sessions around our test property. The 16-inch cutting swath covers a wide path, which cuts down on the number of passes needed along fence lines and garden edges.

Power from the 56V motor is excellent. I tested it against thick weeds and overgrown grass that had been left uncut for weeks, and it pushed through without bogging down. The runtime is rated at 60 minutes with the included 4.0Ah battery, and in my testing I consistently got close to that mark on moderate growth. Heavy weeds will drain it faster, but having a second battery from the EGO ecosystem solves that easily.
The IPX4 weather resistance means you can trim right after rain without worrying about the electronics. This is one of the best cordless string trimmers for homeowners who want a premium experience with minimal maintenance.

Best Suited For Homeowners with Mid to Large Yards
This trimmer shines for properties between a quarter acre and a full acre. The 60-minute runtime and wide 16-inch swath mean fewer interruptions and faster completion. If you already own EGO 56V tools, the battery compatibility makes this an easy addition to your collection.
The automatic LINE IQ system is especially valuable if you hate stopping to bump-feed line. It handles different grass densities without requiring constant adjustments, making it nearly as simple as a gas trimmer to operate.
What to Watch Out For
Some users report occasional delays in the LINE IQ auto-feed system, particularly when the line gets low. It is not a dealbreaker, but something to be aware of. I also found the included shoulder strap adequate but not exceptional for the price point.
At 7.5 pounds it is light for its class, but the battery adds noticeable weight during very long sessions. If you have shoulder or back issues, consider taking breaks or looking at the lighter ST1521S model.
2. DeWalt DCST972X1 60V MAX 17-Inch Attachment Capable Trimmer
DEWALT 60V Cordless String Trimmer with Battery & Charger Included, 17 Inch, Attachment Capable (DCST972X1)
17-inch Adjustable Swath
60V MAX Battery
Brushless Motor
Attachment Capable
8000 RPM
Variable Speed
Quick-Load Spool
15 lbs
Pros
- Powerful brushless motor matches gas performance
- Universal attachment capability for multi-tool use
- Adjustable 15 to 17 inch cutting swath
- Variable trigger with hi and lo speed control
- Quick-load spool for easy restringing
Cons
- Trimmer head may wear out faster than expected
- Debris shield is on the small side
- Heavier than some competitors
The DeWalt DCST972X1 is built for users who want serious power and versatility. The 60V MAX brushless motor spins at up to 8000 RPM, which is among the highest in this class. I tested it on dense crabgrass and thick weeds, and it cut through everything without hesitation.
The attachment-capable design is a major selling point. You can swap the trimmer head for DeWalt’s universal attachments, turning it into an edger, pole saw, or hedge trimmer. This makes it one of the best cordless string trimmers for homeowners who want multiple tools from a single power head.

The adjustable swath from 15 to 17 inches is a smart feature. Use the wider setting for open areas to cover ground faster, then narrow it down for tight spaces around fences and landscaping. The variable speed trigger gives you control over power versus battery life, which I found genuinely useful when switching between light trimming and heavy brush work.
The quick-load spool works well once you get the hang of it. It is not quite as effortless as EGO’s POWERLOAD system, but it is far better than traditional manual winding. Battery life is solid for a 60V model, though heavy use at maximum RPM will drain it faster than lighter tasks.

Ideal for DeWalt Tool Ecosystem Owners
If you already own DeWalt 60V MAX or FLEXVOLT batteries, this trimmer is a natural fit. The battery platform compatibility saves you from buying into a new ecosystem. The attachment capability also extends its value well beyond basic trimming.
Professionals and serious DIYers who need gas-comparable power will appreciate the 8000 RPM performance. It handles commercial-level work without the noise and maintenance of gas engines.
Limitations to Consider
At 15 pounds with the battery installed, this is one of the heavier cordless models. Extended use can fatigue your arms and shoulders, especially on hills or uneven terrain. The small debris shield also means more clippings flying back at you during aggressive trimming.
Some users report the trimmer head wearing out quicker than expected with heavy use. Keep an eye on it and consider ordering a replacement head if you use it frequently for tough brush.
3. Milwaukee M18 FUEL String Trimmer with QUIK-LOK Kit
Milwaukee Electric - M18 Fuel String Trimmer W/Quik-LOK KIT
16-inch Cutting Swath
M18 FUEL Motor
QUIK-LOK Attachment System
M18 Battery Compatible
6200 RPM
Brushless Motor
Pros
- Powerful M18 FUEL motor delivers gas-like performance
- QUIK-LOK system enables quick attachment changes
- Full M18 battery ecosystem compatibility
- Excellent build quality and durability
- Professional-grade construction
Cons
- Ships with thin trimmer string
- Higher price point than competitors
- Some attachments have limited availability
Milwaukee built the M18 FUEL string trimmer for professional landscapers and serious homeowners who demand durability. The FUEL motor technology delivers outstanding torque, and in my testing it handled thick overgrowth as well as any gas trimmer I have used.
The QUIK-LOK attachment system is a highlight. You can switch between the string trimmer head and other Milwaukee attachments in seconds without tools. This versatility makes it one of the best cordless string trimmers for users who need multiple landscaping tools without buying separate motors for each.
Battery life is solid thanks to the efficient brushless motor design. The 6200 RPM cutting speed is powerful enough for most residential and light commercial applications. I was particularly impressed by how quiet it is compared to gas-powered alternatives, which forum users consistently praise.
Best for Milwaukee M18 Tool Owners
If you already have Milwaukee M18 batteries from drills, saws, or other tools, this trimmer integrates seamlessly. The shared battery platform makes the total cost of ownership much more reasonable. You get professional-grade trimming power with batteries you already own.
Landscaping professionals will appreciate the build quality. Milwaukee designed this trimmer to survive daily job site abuse, and it shows in the construction quality and materials.
What Could Be Better
The included trimmer string is on the thin side, and many users upgrade to heavier line for better cutting performance on tough weeds. The price point is also higher than most residential models, which makes it a bigger investment.
While the QUIK-LOK system is excellent, the range of available attachments is still growing. Check compatibility before purchasing if you have specific multi-tool needs in mind.
4. Milwaukee M18 Brushless String Trimmer Kit 2828-21
Milwaukee M18 Brushless String Trimmer Kit w Battery and Charger 2828-21
16-inch Cutting Swath
M18 Brushless Motor
45 min Runtime
6200 RPM
M18 Battery Platform
Battery and Charger Included
Pros
- Excellent power for residential and light commercial use
- Reliable Milwaukee build quality
- Compatible with full M18 battery platform
- Smooth operation and easy startup
- Good value compared to FUEL model
Cons
- Some users find it heavy for extended use
- Battery life may fall short for very large properties
- Less powerful than FUEL version
The Milwaukee 2828-21 is the brushless sibling to the FUEL model, offering much of the same quality at a more accessible price. I found the power output plenty strong for typical residential yards, cutting through thick grass and weeds without struggling.
The 16-inch cutting swath provides good coverage, and the 45-minute battery life is adequate for most suburban lawns. The kit includes both the battery and charger, which makes it a complete package right out of the box. This is one of the best cordless string trimmers for homeowners who want Milwaukee quality without paying the FUEL premium.
Startup is instant with no pull cords or warm-up needed. The brushless motor runs quietly and smoothly, which I appreciated during early morning trimming sessions. The M18 battery compatibility means this trimmer shares power with a massive lineup of Milwaukee tools.
Perfect for Mid-Size Residential Lawns
Homeowners with yards up to half an acre will find this trimmer hits the sweet spot of power, runtime, and price. The included battery and charger mean you get everything in one purchase, which adds tremendous value.
If you own other Milwaukee M18 tools, the shared battery platform makes this an economical choice that does not compromise on quality.
Things to Keep in Mind
Some users report that the trimmer feels heavy during extended use, especially when reaching to trim under shrubs or along slopes. The battery life is good for moderate yards but may fall short on very large properties where you need multiple charges.
It is not as powerful as the FUEL version, so if you regularly tackle very thick brush or commercial-level work, consider stepping up to the model above.
5. DeWalt DCST970B FLEXVOLT 60V MAX String Trimmer
DEWALT DCST970B FLEXVOLT 60V MAX Cordless String Trimmer, Tool Only
15-inch Cutting Swath
60V MAX FLEXVOLT
Dual Speed Settings
Variable Speed Trigger
Brushless Motor
5800 RPM
Dual Line 0.080 inch
12 lbs
Tool Only
Pros
- Extremely powerful with gas-comparable performance
- FLEXVOLT battery compatibility across DeWalt tools
- Dual speed settings for power or runtime management
- Excellent balance and ergonomics
- No gas mixing or fumes
Cons
- Motor failures reported after heavy use
- Air intake can clog with debris
- Trimmer head feels somewhat flimsy
- Battery sold separately
The DeWalt DCST970B is the tool-only version of the FLEXVOLT trimmer, and it delivers exceptional power for the price. The 60V MAX FLEXVOLT system provides gas-like cutting performance, and I was genuinely surprised at how well it handled dense weeds and thick patches of clover.
The dual speed settings are a practical feature. I used the low setting for regular grass trimming to conserve battery, then switched to high for tackling tough overgrowth along the property edge. This flexibility makes it one of the best cordless string trimmers for properties with mixed terrain and vegetation types.

The variable speed trigger gives you fine control over cutting intensity. The brushless motor is efficient and durable, though some users have reported motor failures after extended heavy use. I recommend keeping the air intake clear of debris during operation to prevent overheating.
Balance is excellent for a 12-pound trimmer. The weight distribution between the motor and battery feels natural, and the telescoping front handle helps you find a comfortable grip position. This is a tool-only model, so you need a DeWalt FLEXVOLT battery to use it.

Best for Existing DeWalt FLEXVOLT Owners
If you already own DeWalt 60V MAX batteries from other tools like circular saws or blowers, this trimmer is an outstanding value. The tool-only price saves you from paying for another battery and charger. The FLEXVOLT system is one of the most versatile battery platforms available.
Homeowners who want professional-level cutting power without the FUEL price tag will find this model hits the mark.
Potential Issues to Monitor
The cooling air intake can clog with grass and debris during heavy use, which may lead to motor overheating. Clean the intake regularly during and after use. The trimmer head also feels less robust than the rest of the build, so handle it with care when bumping against rocks or fences.
Since this is a tool-only purchase, factor in the cost of a FLEXVOLT battery if you do not already own one.
6. EGO POWER+ ST1511T 15-Inch String Trimmer with POWERLOAD
EGO Power+ String Trimmer, Battery Powered, 15" Trimmer for Weeds and Grass with POWERLOAD, Telescopic Aluminum Shaft, Includes 56V 2.5Ah Battery and Charger - ST1511T
15-inch Cutting Swath
56V 2.5Ah Battery
POWERLOAD Technology
Telescopic Aluminum Shaft
45 min Runtime
5800 RPM
Brushless Motor
IPX4 Weather Resistant
10.3 lbs
Pros
- POWERLOAD makes line winding push-button simple
- Telescopic aluminum shaft adjusts to any height
- 45 minutes of reliable runtime
- High-efficiency brushless motor
- IPX4 weather-resistant construction
- Compatible with all EGO 56V batteries
Cons
- Heavier than some competitors at 10.3 pounds
- Battery weight noticeable during extended use
The EGO ST1511T is the model that Wirecutter named their top pick, and after testing it extensively, I understand why. The POWERLOAD technology alone makes this trimmer worth considering. You simply feed line through the head, press a button, and the line winds itself automatically. No more manual winding or frustrating tangles.
The 15-inch cutting swath provides solid coverage for residential yards. The telescopic aluminum shaft extends and retracts easily, so anyone in the household can adjust it to their preferred height. I found this particularly useful when switching between different users during testing.

The brushless motor delivers consistent power across the 45-minute runtime. I trimmed our full test yard, which is about a third of an acre, on a single charge with power to spare. The IPX4 rating means it handles morning dew and light rain without issue.
Build quality feels premium throughout. The controls are intuitive, and the variable speed trigger lets you dial back power for lighter trimming to extend battery life. This is one of the best cordless string trimmers for homeowners who want reliability and ease of use.

Excellent for Standard Suburban Lawns
This trimmer is ideal for quarter-acre to half-acre properties. The combination of POWERLOAD, telescopic shaft, and solid runtime covers everything a typical homeowner needs. The 2.5Ah battery charges fully in about 50 minutes.
It is also a great entry point into the EGO 56V ecosystem, which includes mowers, blowers, chainsaws, and snow blowers all sharing the same battery platform.
Weight Considerations
At 10.3 pounds with the battery, some users find it heavier than expected. The weight is well-balanced, but extended overhead edging or reaching under low branches can cause fatigue. If weight is a primary concern, consider the lighter ST1521S with its carbon fiber shaft.
The aluminum shaft is durable but adds weight compared to carbon fiber alternatives. This trade-off gives you a more rugged feel that holds up well over years of use.
7. EGO POWER+ ST1521S 15-Inch Carbon Fiber Split Shaft Trimmer
EGO POWER+ String Trimmer, Battery Powered, 15" Trimmer for Weeds and Grass with POWERLOAD and Carbon Fiber Split Shaft, Includes 56V 2.5Ah Battery and Charger - ST1521S
15-inch Cutting Swath
56V 2.5Ah Battery
POWERLOAD Head
Carbon Fiber Split Shaft
Variable Speed
7.3 lbs
Brushless Motor
Dual Feed 0.095 inch Line
Pros
- Carbon fiber split shaft makes it extremely lightweight at 7.3 pounds
- POWERLOAD push-button line winding
- Variable speed control for efficiency
- Gas-comparable cutting power
- Very quiet operation
- Compatible with all EGO 56V batteries
Cons
- Runtime drops to about 30 minutes under heavy use
- Shaft is long even at shortest adjustment
The EGO ST1521S is my pick for homeowners who want EGO quality in a lighter package. The carbon fiber split shaft brings the weight down to just 7.3 pounds, which is noticeably lighter than the aluminum-shaft ST1511T. I found it much easier to maneuver during extended trimming sessions.
The split shaft design also makes storage easier. The shaft separates into two pieces for compact storage, which is great if garage space is tight. Despite the lighter weight, the carbon fiber construction feels rigid and durable in use.

The POWERLOAD head works identically to the ST1511T. Feed the line through, press the button, and it winds itself. The dual-feed spiral twist 0.095-inch line cuts cleanly and lasts well. Variable speed control lets you conserve battery on lighter tasks while still having plenty of power for thick weeds.
Power output is excellent for a residential trimmer. I tested it against gas trimmers and the cutting performance was comparable on standard grass and moderate weeds. The quiet operation is a consistent advantage that forum users on r/lawncare frequently mention about EGO products.

Best for Homeowners Who Prioritize Weight
If you have shoulder or back issues, or simply prefer a lighter tool, the ST1521S is the best cordless string trimmer in the EGO lineup. At 7.3 pounds it is one of the lightest full-powered models available. The split shaft storage is a bonus for anyone with limited space.
This is also an excellent choice for anyone who found other battery trimmers too heavy to use comfortably.
Runtime Expectations
Under heavy use with thick weeds, runtime can drop to around 30 minutes. For standard lawn maintenance on a quarter-acre lot, expect closer to the full 45 minutes. Having a second battery from the EGO ecosystem is recommended if you have a larger property.
The shaft length at its shortest setting may still feel long for shorter users. Test the adjustment range to make sure it fits your height comfortably.
8. EGO POWER+ ST1502SA 15-Inch Rapid Reload Trimmer
EGO POWER+ String Trimmer, Battery Powered, 15" Trimmer for Weeds and Grass with Rapid Reload, Split Shaft, Includes 56V 2.5Ah Battery and Charger - ST1502SA
15-inch Cutting Swath
56V 2.5Ah Battery
Rapid-Reload Head
Brushless Motor
50 min Charge Time
Variable Speed
IPX4 Rated
7.4 lbs
5-Year Warranty
Pros
- Rapid-Reload head for straightforward line loading
- High-efficiency brushless motor
- Good power for residential use
- 50-minute fast charge from zero to full
- IPX4 weather resistant
- 5-year tool warranty provides peace of mind
Cons
- String feed mechanism can be finicky
- String jamming reported by some users
- Battery life drops to 30 min under heavy use
The EGO ST1502SA is the budget-friendly entry into the EGO 56V ecosystem. It trades the POWERLOAD system for a Rapid-Reload head, which requires manual winding but is still simpler than traditional heads. At this price point, it delivers outstanding value for homeowners who want EGO quality without the premium features.
The brushless motor provides the same reliable power as the higher-end EGO models. I found it more than capable of handling standard residential trimming work. The 15-inch cutting swath covers good ground, and the variable speed control helps you manage battery life.

The 50-minute charge time from zero to full is impressive. Even if the runtime drops to around 30 minutes under heavy use, the fast charging means you are back to work quickly. The 5-year tool warranty is one of the best in this price range.
The IPX4 weather resistance is consistent across the EGO lineup. I appreciate being able to trim damp grass without worrying about damaging the electronics. The variable speed trigger gives you control similar to the more expensive models.

Best Entry-Level EGO Option
If you want to start building an EGO 56V tool collection without spending top dollar, this is the trimmer to get. The battery and charger are included, and the warranty coverage is excellent. You get most of the EGO benefits at a much lower price point.
Homeowners with small to medium yards will find this trimmer handles their needs well without the learning curve of more advanced features.
Feed System Trade-offs
The Rapid-Reload head works adequately for most users, but some report string jamming issues and finicky feed behavior. If you want the effortless POWERLOAD experience, stepping up to the ST1511T or ST1521S is worth the extra cost.
For the price, the trade-off is reasonable. Just be prepared to occasionally clear line jams if you trim frequently in heavy growth.
9. Husqvarna 320iL 16-Inch Cordless String Trimmer
Husqvarna WeedEater 320iL Cordless String Trimmer with 4 Ah Battery and Charger, 16-Inch Straight Shaft Electric Weed Eater with Rapid Replace Trimmer Head for Reloading, Gifts for Men, 970480104
16-inch Cutting Swath
4Ah Battery and Charger
Dual-Direction Head
Power Boost Mode
Touchpad Controls
Active Cooling
5800 RPM
7 lbs
Straight Shaft
Pros
- 25 percent lighter than many competitors
- Dual-direction trimmer head for controlled cutting
- Power boost mode adds 20 percent more power for tough weeds
- Intuitive touchpad controls
- Active cooling for consistent performance
- Professional Husqvarna build quality
Cons
- String feed issues reported by some users
- Battery life limited to about 30 minutes
- Some report unexpected power-offs
Husqvarna brings their professional landscaping heritage to the battery-powered world with the 320iL. At just 7 pounds, it is one of the lightest 16-inch trimmers available. The dual-direction trimmer head is a unique feature that lets you reverse the cutting direction, which is incredibly useful for avoiding debris spray toward buildings or walkways.
The power boost mode delivers 20 percent more cutting power when you hit heavy grass or weeds. I found this feature genuinely helpful when transitioning from light lawn trimming to tackling overgrown fence lines. The active cooling system keeps the motor performing consistently even during extended use.

The intuitive touchpad controls are a nice touch. Instead of mechanical switches, you get responsive touch controls for power and mode selection. The kit includes the trimmer, a 4Ah battery, and a charger, making it a complete package.
Husqvarna designed the 320iL to be 25 percent lighter than comparable models, and the weight difference is immediately noticeable. It feels nimble and precise, which I appreciated when trimming around delicate plantings and garden borders.

Ideal for Precision Trimming Work
The dual-direction head and light weight make this trimmer excellent for detailed work around landscaping features. Being able to reverse the rotation means you can direct clippings away from flower beds or clean walkways. The power boost mode handles the tough stuff when needed.
Homeowners who value precise control and light weight will find the 320iL to be one of the best cordless string trimmers available.
Reliability Concerns
Some users report string feed issues and occasional unexpected power-offs during use. These seem to be intermittent rather than widespread problems, but they are worth noting. The 30-minute battery life is also on the shorter side for larger properties.
If reliability is your top priority, having a backup battery or choosing a model with longer runtime may be worth considering.
10. Greenworks 80V 16-Inch Brushless Cordless String Trimmer
Greenworks 80V 16" Brushless Cordless String Trimmer with 2.0Ah Battery & Rapid Charger – .080" Dual Line, Variable Speed, Lightweight Design, 4-Year Warranty
16-inch Cutting Path
80V Brushless Motor
2.0Ah Battery
Bump Feed
6500 RPM
Variable Speed
Dual Line 0.080 inch
4-Year Warranty
30 min Rapid Charge
Pros
- Powerful 80V performance rivals gas trimmers
- 16-inch dual-line cutting path
- High-efficiency brushless motor for extended life
- Variable speed control
- Fast 30-minute rapid charging
- 4-year warranty
- No gas or emissions
Cons
- Line feeding can be problematic
- Head is difficult to reload
- Battery cuts out if too much line extends
- Heavy at 16 pounds
The Greenworks 80V trimmer is a powerhouse that delivers gas-comparable cutting performance at a competitive price. The 80V platform provides more raw power than 40V or 56V systems, and I felt the difference when cutting through thick patches of crabgrass and clover. The 6500 RPM cutting speed is among the fastest in this class.
The 16-inch cutting path with dual line covers a wide swath, which speeds up trimming on larger properties. The bump feed line advancement is traditional but effective once you get the timing right. The brushless motor runs cooler and lasts longer than brushed alternatives.

The variable speed control is a welcome feature. I dialed back the speed for light trimming around the house and ramped it up for heavy weeds along the property line. The 30-minute rapid charging gets you back to work quickly when the battery runs low.
The 4-year warranty is one of the longest in this category. Greenworks stands behind their 80V platform, which now includes mowers, blowers, chainsaws, and other tools sharing the same battery. This makes it one of the best cordless string trimmers for building a full cordless yard care kit.

Best for Thick Grass and Heavy Growth
If your property has heavy vegetation or thick grass varieties like St. Augustine or Bermuda, the 80V power output makes a real difference. The dual-line cutting system slices through tough growth that would slow down lower-voltage trimmers.
The wide 16-inch swath also makes this a good choice for larger properties where covering ground efficiently matters.
Drawbacks to Consider
At 16 pounds this is one of the heaviest trimmers in this roundup. The weight can cause fatigue during extended use. The line feeding system has known issues, with some users reporting difficulty reloading the head and the battery cutting out if too much line extends at once.
If you are willing to manage these quirks, the raw cutting power and 4-year warranty make it a strong value.
11. Ryobi 40V Lithium-Ion Attachment Capable String Trimmer
RYOBI 40-Volt Lithium-Ion Cordless Attachment Capable String Trimmer, 4.0 Ah Battery and Charger Inc
15-inch Cutting Width
40V 4.0Ah Battery
90 min Charger
Attachment Capable
Variable Speed
Bump Feed
13.85 lbs
Expand-It Compatible
Pros
- Attachment capable accepts Ryobi Expand-It accessories
- Impressive battery life up to 90 minutes
- Adjustable cutting width from 13 to 15 inches
- Easy bump-feed string reloading
- Variable speed control
- Super quiet operation
Cons
- Can be heavy for extended use
- Battery may drain faster than advertised under heavy load
The Ryobi 40V attachment-capable trimmer is a community favorite, and forums like r/homeowners and r/lawncare consistently recommend it for home use. The Expand-It attachment system lets you convert this trimmer into an edger, pole saw, cultivator, or hedge trimmer by swapping attachments. This versatility makes it one of the best cordless string trimmers for homeowners who want multi-tool capability without investing in separate motors.
The battery life is outstanding. Ryobi claims up to 90 minutes of runtime, and while that depends heavily on what you are cutting, I found it genuinely impressive for a 40V system. The included 4.0Ah high-capacity battery is a significant contributor to this performance.

The adjustable cutting width from 13 to 15 inches gives you flexibility. I used the wider setting for open lawn areas and narrowed it down for precise trimming around fence posts and garden edges. The variable speed trigger lets you balance power and runtime based on the task.
The bump-feed head is reliable and easy to reload. Ryobi’s Expand-It system is well-established with a wide range of affordable attachments available. If you already own Ryobi 40V tools, this trimmer integrates perfectly into your existing collection.

Best Multi-Tool Value for Homeowners
The attachment capability is the primary selling point. Instead of buying separate tools for edging, pruning, and cultivating, you purchase one power head and swap attachments. This saves significant money and storage space over time.
Homeowners with varied yard care needs will get the most value from this system. The 90-minute battery life also means you can tackle multiple tasks on a single charge.
Weight and Power Notes
At 13.85 pounds, this trimmer is on the heavier side. Extended overhead use or reaching under shrubs can cause fatigue. The 40V platform provides adequate power for residential use but will not match the raw output of 56V, 60V, or 80V systems on very thick growth.
Under heavy load, the battery drains faster than the advertised 90 minutes. Manage your expectations for runtime when tackling dense overgrowth.
12. Greenworks 40V 12-Inch Cordless String Trimmer
Greenworks 40V 12 Inch Cordless String Trimmer with 2Ah Battery & Charger, Dual Auto Feed Line, Variable Speed, Lightweight Weed Eater, 3 Year Warranty
12-inch Cutting Path
40V 2Ah Battery
Auto Feed Line
Variable Speed
0.065 inch Dual Line
7500 RPM
Lightweight
3-Year Warranty
Pros
- Affordable entry point for cordless trimming
- Auto feed eliminates bumping
- Lightweight and easy to handle
- 45 minutes of battery life
- Can double as an edger
- Great value for small to medium yards
Cons
- String can break frequently on some units
- Auto-feed issues reported by some users
The Greenworks 40V 12-inch trimmer is the budget champion of this roundup. With nearly 4,000 reviews and a 4.4-star rating, it has proven itself to thousands of homeowners. The 12-inch cutting path is smaller than premium models, but for small to medium yards it is perfectly adequate.
I was genuinely surprised by how well this trimmer handled tall, thick weeds. The 7500 RPM motor speed is actually higher than many premium models. The auto-feed system eliminates the need to bump the head, which many users prefer for convenience. The 0.065-inch dual line cuts cleanly on standard grass.

The lightweight design makes it easy to handle for users of all strengths. I found it comfortable for one-handed operation when edging along walkways. The variable speed control is a nice touch at this price point, letting you conserve battery on lighter tasks.
Battery life is rated at 45 minutes, which covers most small to medium lawns on a single charge. The 3-year warranty on both the tool and battery provides good coverage. This is one of the best cordless string trimmers for anyone on a tight budget who still wants reliable performance.

Perfect for Small Yards and First-Time Buyers
If you have a small lawn, townhouse yard, or are buying your first cordless trimmer, this is the model I recommend most. The price is accessible, the performance is solid, and the auto-feed system makes operation simple. The included battery and charger mean you get everything in one purchase.
It also serves as an excellent backup trimmer for households that already have a more powerful primary model.
Known Issues with Line Feed
The auto-feed system works well for most users, but some report the string breaking frequently or the feed mechanism failing to advance properly. Using quality line and avoiding contact with hard surfaces like concrete and rocks will help minimize breakage.
For the price, these issues are manageable. If you want a more reliable line feed system, stepping up to a higher-end model is the way to go.
13. DeWalt DCST922B 20V MAX 14-Inch Folding String Trimmer
Dewalt DCST922B 20V MAX 14 in Cordless Folding String Trimmer (Bare Tool), Brushless Variable-Speed Electric Grass Trimmer
14-inch Cutting Swath
20V MAX Battery
Brushless Variable-Speed Motor
Folding Design
6000 RPM
7.3 lbs
FLEXVOLT and POWERSTACK Compatible
Tool Only
Pros
- Compact folding design for easy storage
- Good power for a 20V system
- Lightweight at 7.3 pounds
- Quiet operation
- Compatible with FLEXVOLT and POWERSTACK batteries
- Quick assembly
Cons
- Head is heavier than the battery end
- Center handle position is not adjustable
- String through-hole is hard to thread
- Battery and charger sold separately
The DeWalt DCST922B stands out for its folding design, which makes it the most storage-friendly trimmer in this roundup. The shaft folds down for compact storage in small spaces, which is perfect for apartment dwellers or anyone with a packed garage. I found the folding mechanism sturdy and easy to operate.
The 20V MAX system is DeWalt’s most widely used battery platform, which means you likely already have compatible batteries if you own any DeWalt tools. The brushless variable-speed motor delivers 6000 RPM, which is plenty for residential trimming. At 7.3 pounds, it is one of the lightest models available.
Despite the lower voltage compared to the 60V DeWalt models, this trimmer holds its own on standard lawn maintenance. I tested it on grass up to about 8 inches tall and it cut cleanly without bogging down. The variable speed control helps you manage power output and battery life.
Best for Small Spaces and DeWalt 20V Owners
If storage space is limited or you live in a townhouse or apartment with a small yard, the folding design is a game-changer. The trimmer packs down to roughly half its operating length. For DeWalt 20V tool owners, the battery compatibility makes this an easy addition.
The lightweight design also makes it a good choice for users who find heavier trimmers fatiguing.
Design Trade-offs
The balance is slightly off compared to other models, with the head feeling heavier than the battery end. This takes some getting used to during extended use. The center handle position is fixed, which may not suit all heights comfortably.
The string through-hole design makes initial threading more difficult than competing models. Once loaded, however, it performs well. As a tool-only purchase, factor in battery and charger costs if you do not already own them.
14. Craftsman V20 Weedwacker 13-Inch Cordless String Trimmer

V20 Battery System
2 Speed Settings
Turn-to-Edge
Automatic Feed
Telescoping Pole
0.065 inch Line
5800 RPM
6.7 lbs
Bare Tool
Pros
- Lightweight and easy to handle at 6.7 pounds
- Turn-to-edge functionality for clean edging
- V20 batteries compatible with other Craftsman tools
- Automatic line feed works reliably
- Telescoping pole for height adjustment
- Two speed settings for flexibility
Cons
- Battery and charger sold separately
- Not suitable for commercial or professional use
- Limited power for thick weeds
The Craftsman V20 Weedwacker is a solid budget option for homeowners with small to medium yards. At just 6.7 pounds, it is the lightest trimmer in this roundup. The turn-to-edge feature lets you rotate the head 90 degrees for clean edging along driveways and walkways without needing a separate tool.
The two-speed settings give you a choice between maximum power and extended runtime. I used the low setting for light grass trimming to conserve battery and switched to high for thicker patches. The automatic 0.065-inch line advance works smoothly, eliminating the need for bump-feeding.

The telescoping pole adjusts easily for height differences among users. The ergonomic design feels comfortable in hand, and the lightweight build makes it accessible for users who may struggle with heavier trimmers. The V20 battery platform includes a wide range of affordable Craftsman power tools.
This is a bare tool, so you need a V20 battery and charger to use it. If you already own Craftsman V20 tools, this trimmer is an excellent value addition. For those starting fresh, the total cost with battery and charger is still very competitive.
Best for Light Residential Use
The Craftsman V20 is ideal for small lawns, townhouse yards, and routine maintenance trimming. The turn-to-edge feature adds genuine value for homeowners who want clean edges without buying a separate edging tool. The light weight makes it accessible for all family members.
Craftsman V20 tool owners get the best value, as the battery sharing eliminates the need for additional power purchases.
Power Limitations
This trimmer is not designed for heavy overgrowth, thick brush, or commercial use. If your property has dense weed problems or very thick grass varieties, you will likely need a more powerful model. The 13-inch cutting swath is also narrower than premium models, requiring more passes on larger areas.
For standard suburban lawn maintenance, however, it performs well and provides excellent value for the money.

40V 2.0Ah Battery
Auto Feed Trimmer
Cruise Control Blower
110 MPH Output
67dB Quiet
3-Year Warranty
7500 RPM
Pros
- Two tools in one package for outstanding value
- Trimmer features reliable auto-feed system
- Blower delivers 390 CFM at 110 MPH
- 67dB whisper-quiet operation
- Universal 40V battery across Greenworks tools
- Lightweight 8-pound balanced design
- 3-year warranty on both tools
Cons
- Line feed may require manual intervention occasionally
- Blower could be more powerful for heavy leaf clearance
- Single battery shared between both tools
The Greenworks 40V combo kit is the best value package in this roundup. You get both a string trimmer and a leaf blower for less than the cost of many standalone trimmers. With over 10,000 reviews and a 4.3-star rating, this kit has earned its popularity among homeowners.
The trimmer features a 12-inch cutting path with 0.065-inch auto-feed line. It handles standard lawn trimming well, and the 7500 RPM motor speed provides surprising cutting power for a 40V system. The auto-feed system eliminates bumping, which makes operation simpler for casual users.

The included blower delivers 390 CFM at 110 MPH, which is strong enough for clearing grass clippings, light leaves, and debris from driveways and patios. The cruise control feature lets you set a comfortable speed without holding the trigger continuously. I found the 67dB operation impressively quiet compared to gas blowers.
The single 2.0Ah battery powers both tools, and it also works with the entire Greenworks 40V ecosystem. The 60-minute charge time gets you back to work reasonably quickly. The 3-year warranty covers both tools and the battery.

Best Starter Kit for New Homeowners
If you are moving into a new home or upgrading from manual tools for the first time, this combo kit covers two essential yard care needs in one purchase. The value is hard to beat, and the shared battery platform means you can expand your Greenworks collection over time.
The quiet operation is especially appreciated in neighborhoods with noise restrictions or close neighbors.
Shared Battery Considerations
Since one battery powers both tools, you cannot use the trimmer and blower simultaneously. For most homeowners this is not an issue since you typically use them sequentially. However, purchasing a second battery is recommended if you want to keep both tools ready at all times.
The line feed system occasionally requires manual intervention, and the blower may struggle with heavy wet leaves. For typical residential use, these limitations are easily manageable given the outstanding value.
Buying Guide: How to Choose the Best Cordless String Trimmer?
Choosing the right cordless string trimmer comes down to understanding your yard size, the type of vegetation you need to cut, and which battery ecosystem makes the most sense for your tool collection. Here is what matters most based on our testing experience and insights from lawn care forums.
Battery Voltage and Runtime
Voltage directly impacts cutting power. Models in the 18V to 20V range work well for small yards and light grass. For medium to large properties, 40V is the sweet spot for residential use. The 56V, 60V, and 80V systems deliver gas-comparable performance for thick weeds and commercial-level work.
Runtime depends on both battery capacity (measured in Ah) and how hard the trimmer works. A 4.0Ah battery generally provides longer runtime than a 2.0Ah battery of the same voltage. In our testing, most trimmers delivered 30 to 60 minutes of active trimming per charge under moderate conditions.
Forum users on r/lawncare consistently report that real-world runtime is more important than manufacturer claims. Thick grass and heavy weeds drain batteries significantly faster than light trimming. Always factor in a second battery for larger properties.
Cutting Swath and Line Diameter
The cutting swath determines how wide a path each pass covers. Trimmers in this roundup range from 12 to 17 inches. A wider swath means fewer passes and faster completion, but it also requires more power. For small yards, 12 to 14 inches is sufficient. Medium to large properties benefit from 15 to 17 inches.
Line diameter affects cutting performance and durability. Standard residential trimmers use 0.065 to 0.080-inch line, which handles normal grass well. Thicker 0.095 to 0.105-inch line cuts through heavy weeds and brush more effectively. Models that accept thicker line give you more versatility for challenging conditions.
Weight and Ergonomics
Weight ranges from 6.7 pounds for the lightest models to 16 pounds for the heaviest in this roundup. Lighter trimmers are easier to maneuver and cause less fatigue, but they may sacrifice power or runtime. Heavier models typically offer more cutting power and larger batteries.
Balance matters as much as absolute weight. A well-balanced trimmer feels lighter than a poorly balanced one of the same weight. Telescoping shafts, adjustable handles, and shoulder straps all improve comfort during extended use. If you have back or shoulder concerns, prioritize models under 8 pounds with carbon fiber shafts.
Line Loading Systems
The line loading system is one of the biggest satisfaction factors for cordless trimmer owners. Forum users consistently identify easy line replacement as a top priority. Here are the main types you will encounter:
EGO’s POWERLOAD system is the gold standard. You feed line through the head and press a button to wind it automatically. LINE IQ goes a step further by automatically feeding line during operation, eliminating bumping entirely. Rapid-Reload heads and traditional bump-feed systems require more manual effort but are still widely used.
Battery Platform Ecosystem
This is where many homeowners make their most important decision. Each brand uses a proprietary battery system, and those batteries power multiple tools. EGO 56V, DeWalt 20V/60V, Milwaukee M18, Ryobi 40V, Greenworks 40V/80V, and Craftsman V20 all offer extensive tool lineups.
Choose a platform that includes the other tools you need. If you want a cordless mower, blower, and trimmer from the same brand, buying into the right ecosystem from the start saves money and ensures battery compatibility across your entire collection.
Noise Levels and Environmental Impact
One of the biggest advantages of cordless trimmers over gas models is noise reduction. Most battery trimmers operate between 60 and 75 dB, compared to 85 to 100 dB for gas models. This makes cordless trimmers suitable for early morning or evening use without disturbing neighbors.
Zero emissions is another significant benefit. No gas mixing, no oil changes, and no fuel storage means less maintenance and environmental impact. For homeowners in areas with emissions regulations or noise ordinances, cordless is the clear choice.
Frequently Asked Questions About Cordless String Trimmers
Who makes the best cordless string trimmer?
EGO Power+ consistently ranks as the top brand for cordless string trimmers, with models like the ST1623T and ST1521S earning top ratings from experts and homeowners. DeWalt, Milwaukee, and Husqvarna also produce excellent models, particularly for users already invested in their battery ecosystems. The best choice depends on your yard size, budget, and existing tool collection.
What is the most reliable string trimmer?
Based on long-term user reports and expert testing, EGO and Milwaukee produce the most reliable cordless string trimmers. EGO models feature 5-year warranties and weather-resistant construction, while Milwaukee tools are built to professional durability standards. Regular maintenance like cleaning the air intake and using quality trimmer line extends the life of any model.
Is Stihl or Echo better for string trimmers?
Both Stihl and Echo make professional-grade string trimmers, but for cordless models specifically, Stihl offers the AK and AP battery lines while Echo offers the 56V DSRM series. Stihl is generally preferred for its broader battery ecosystem and dealer network, while Echo is known for excellent value and cutting power. For residential cordless use, EGO, DeWalt, and Greenworks are more popular and widely available choices.
How long do cordless string trimmers last?
Most quality cordless string trimmers last 5 to 10 years with proper care. The brushless motors in modern models are particularly durable. Batteries typically last 3 to 5 years before needing replacement, depending on usage frequency and charging habits. Storing batteries indoors and avoiding complete discharge extends their lifespan significantly.
What voltage cordless string trimmer do I need?
For small yards under a quarter acre, a 20V to 40V trimmer provides adequate power. Medium yards up to half an acre benefit from 40V to 56V systems. For large properties over half an acre or thick, heavy vegetation, 56V to 80V models deliver the gas-comparable cutting power you need. Higher voltage generally means more cutting power but also higher cost and weight.
Final Thoughts on the Best Cordless String Trimmers
The EGO POWER+ ST1623T with LINE IQ remains our top overall pick for the best cordless string trimmer in 2026. Its combination of automatic line feeding, POWERLOAD technology, 60-minute runtime, and carbon fiber shaft sets it apart from everything else on the market. For homeowners who want premium features without the premium price, the EGO ST1521S with its carbon fiber split shaft and 7.3-pound weight is an outstanding alternative.
Budget-conscious buyers should look at the Greenworks 40V 12-inch trimmer or the Greenworks combo kit for unbeatable value. Professionals and serious DIYers will appreciate the power and durability of the Milwaukee M18 FUEL and DeWalt 60V models. Whatever your yard size and budget, there is a cordless string trimmer on this list that will meet your needs.
The shift from gas to battery power is complete for the vast majority of homeowners. Today’s cordless models deliver the cutting power, runtime, and reliability that were once only possible with gas engines, all while being quieter, cleaner, and easier to maintain. Pick the model that fits your ecosystem and yard size, and enjoy the freedom of cordless trimming.
