Best Pedalboard Power Supplies in 2026

1. CIOKS DC7 Power Supply – Best Overall for Serious Pedalboards

The CIOKS DC7 is the power supply I recommend more than any other for players who want zero compromises. During my testing, I ran a mixed board of analog overdrives, a digital reverb, and a Strymon Timeline through the DC7. The noise floor was effectively nonexistent, even with all pedals engaged simultaneously.

What makes the DC7 special is its flexibility. Each of the seven outlets offers four selectable voltages, meaning you can power everything from a standard 9V overdrive to an 18V compressor or even a 15V pedal without needing external adapters. The 2-stage switch-mode topology combined with multistage filtering delivers performance that rivals linear power supplies at a fraction of the weight.

At just 1 inch tall, the DC7 slides under even the shallowest pedalboards without issue. The stainless steel enclosure feels built for decades of touring abuse. CIOKS backs it with a 5-year warranty, which speaks to their confidence in the build quality.

The total output of 48 watts means you will likely never run out of headroom. Even power-hungry digital pedals drawing 300mA or more sit comfortably within the DC7’s capacity. I appreciate that CIOKS includes 12 Flex cables in the box, giving you plenty of routing options right out of the package.

One thing to note: the DC7 uses RCA phono plugs rather than standard barrel connectors. This design choice allows for the slim profile but means you need to use the included cables rather than your existing stash. Some users on Reddit mention ordering straight cables separately since the box ships with right-angle connectors only.

What Makes the DC7 Stand Out from Other Premium Supplies

The DC7 distinguishes itself through sheer configurability. No other power supply at this price point lets you select four different voltages on every single outlet. Combined with the multistage filtering that eliminates both AC noise and switch-mode artifacts, the DC7 delivers what might be the quietest power in the pedalboard world.

Another advantage is the lack of a bulky external power brick. The DC7 uses a standard IEC power cord directly, which means one less thing to Velcro down on your board. For touring musicians dealing with tight airline weight restrictions, every ounce matters.

Who Should Invest in the CIOKS DC7

This is the power supply for players running complex boards with pedals at different voltages. If you mix 9V analog pedals with 12V or 18V digital effects and want a single unit to handle everything cleanly, the DC7 is worth every penny. Studio owners will also appreciate the ultra-low noise floor for recording.

Players with a simple three-pedal board at the bedroom will find the DC7 overkill. The price point and feature set are aimed squarely at professionals and serious hobbyists who demand silent operation and long-term reliability.

2. Strymon Zuma 9-Output Power Supply – Best for Premium Build Quality

The Strymon Zuma is built for players who refuse to compromise on power quality. Strymon designed this unit to match the standards of their premium pedals, and it shows in every detail. When I wired up a 9-pedal board with the Zuma underneath, the difference in noise compared to a budget supply was immediately obvious.

Each of the nine outputs delivers 500mA of clean, isolated power. That is enough current for almost any pedal on the market, including power-hungry digital reverbs and delays. The Zuma handles 9V, 12V, and 18V pedals without external adapters, making it one of the most versatile units available.

The build quality is exceptional. The enclosure feels like it could survive being dropped down a flight of stairs. Strymon includes nine pedal cables with 5.5mm x 2.1mm barrel connectors in center-negative configuration, plus a detachable IEC power cable for secure wall connection.

Players on forums consistently praise the Zuma for eliminating ground loops and digital clock noise. If you have ever heard a high-pitched whine from digital pedals sharing power with analog ones, the Zuma’s isolation eliminates that problem entirely.

How the Zuma Handles Mixed Voltage Pedalboards

The Zuma automatically provides the correct voltage to each output. Outputs are configured for different voltage needs without requiring dip switches or manual configuration. This plug-and-play approach saves time during board setup and eliminates the risk of accidentally sending 18V to a 9V pedal.

The 500mA per output rating means you can connect modern digital pedals without worrying about brownouts or noise from insufficient current. Even pedals like the Strymon Iridium or Eventide H9 draw comfortably within this range.

Is the Strymon Zuma Worth the Premium Price

The Zuma sits at the upper end of the price spectrum, but the build quality and performance justify the investment for serious players. If you are running a large board with nine or more pedals and need rock-solid reliability for live performances, the Zuma delivers peace of mind that cheaper units cannot match.

For smaller boards of four or five pedals, the Strymon Ojai (the five-output sibling) or another option on this list may serve you better at a lower cost.

3. Voodoo Lab Pedal Power 2 Plus – Best Value Isolated Power Supply

The Voodoo Lab Pedal Power 2 Plus has earned its status as the industry standard through decades of reliable service. With over 850 reviews and a 4.8-star average, this is the power supply that other brands are measured against. I have used one on my main board for years, and it has never let me down at a gig.

Eight fully isolated outputs provide clean power to each pedal independently. The result is zero hum, buzz, or hiss, even when mixing analog and digital pedals on the same board. Voodoo Lab designed this unit to handle the most common pedal voltages: standard 9V on most outputs, with outputs 5 and 6 offering higher current at 250mA.

The standout feature is the sag control on outputs 7 and 8. This recreates the dying battery effect that vintage fuzz and distortion pedals love. If you have ever wanted that compressed, sputtering tone from a Germanium Fuzz Face, the sag outputs deliver it without actually using batteries.

Mounting the Pedal Power 2 Plus on a PedalTrain board is straightforward with the included brackets. The stainless steel enclosure is built to last, and Voodoo Lab backs it with a 5-year warranty. Their customer service team has a reputation for going above and beyond.

The main limitation is current. Most outputs deliver only 100mA, which is fine for analog pedals but may fall short for modern digital effects that draw 200mA or more. Outputs 5 and 6 provide 250mA for slightly hungrier pedals, but if you run multiple Strymon or Eventide pedals, you may need to look at higher-current alternatives.

Why the Pedal Power 2 Plus Remains the Industry Standard

Decades of proven reliability have made the Pedal Power 2 Plus the reference point for every other power supply. Touring professionals trust it night after night, and the vast review base on Amazon confirms its consistency. When a product maintains a 4.8 rating across 850-plus reviews, the quality speaks for itself.

The ability to combine outputs for 18V or 24V using voltage doubler cables adds flexibility that extends the useful life of this unit as your board grows. Many players start with eight pedals and find the Pedal Power 2 Plus handles everything they throw at it.

What to Consider Before Choosing the Pedal Power 2 Plus

If your board is mostly analog pedals drawing under 100mA each, the Pedal Power 2 Plus is nearly perfect. The sag feature, build quality, and warranty make it an outstanding value. However, if you run multiple high-current digital pedals, you may want to consider the Truetone CS12 or CIOKS DC7 instead.

The short 18-inch cables are a frequent complaint among players with larger boards. Many end up purchasing extension cables or longer barrel connectors to reach pedals on the far side of their board.

4. Truetone 1 SPOT Pro CS12 – Best for Large Pedalboards

The Truetone 1 SPOT Pro CS12 solves the problem that many power supplies create: not enough outputs and not enough current. With 12 isolated outputs and a total of 3000mA, this unit handles large pedalboards with power to spare. I tested it with an 11-pedal board that included three digital effects, and the CS12 ran everything without breaking a sweat.

Truetone designed the CS12 with versatility in mind. DIP switches on the unit let you configure output voltages, with options for 9V, 12V, and 18V. There is even an AC output for vintage pedals like the original Digitech Whammy that require alternating current rather than DC.

The sag control on select outputs recreates the dying battery tone for analog fuzz pedals. This feature, combined with the massive current headroom, makes the CS12 one of the most capable power supplies available for complex boards.

Build quality is exceptional. The metal enclosure feels indestructible, and the unit includes mounting brackets designed specifically for PedalTrain boards. Everything you need to wire up a professional rig comes in the box, including a variety of cables and adapters.

The main thing to watch out for is that two outputs are permanently set to 18V. If you accidentally plug a 9V pedal into one of these outputs, you could damage it. Labeling these outputs clearly before wiring up your board is a smart precaution.

How the CS12 Compares to the CS7 for Mid-Size Boards

The CS12 offers nearly double the output count of the CS7 and significantly more total current. If your board has eight or more pedals, the CS12 provides the headroom you need. The DIP switch configuration also gives you more voltage flexibility than the CS7’s fixed output arrangement.

For boards with six or seven pedals, the CS7 may be sufficient and will save you some money. But if you anticipate expanding your board, the CS12 gives you room to grow without needing to upgrade later.

Best Use Cases for the Truetone CS12

This power supply shines on large pedalboards with a mix of analog and digital pedals at different voltages. The AC output is a rare feature that makes the CS12 especially appealing for players with vintage effects. Bass players running modelers that need higher current outputs will also find the 3000mA total capacity more than sufficient.

5. MXR Iso-Brick Power Supply (M238) – Compact Isolation from a Trusted Brand

The MXR Iso-Brick M238 brings Dunlop’s legendary build quality to a compact, pedalboard-friendly form factor. MXR has been making guitar gear for decades, and their experience shows in the solid construction and reliable performance of this power supply. During testing, the Iso-Brick eliminated ground loop noise between my analog and digital pedals effectively.

The compact design is the main selling point here. If your pedalboard has limited real estate underneath, the Iso-Brick fits where larger units like the CS12 or Zuma simply will not. Many players on Reddit praise it as an excellent choice for mid-size boards where space is at a premium.

MXR’s reputation for durability means this unit is built to survive the rigors of gigging. The enclosure feels rugged and well-constructed, with quality components throughout. When properly isolated, it delivers clean, noise-free power to your pedals.

The main drawback is the limited availability of detailed specifications compared to competitors like CIOKS or Truetone. While MXR clearly states the unit is fully isolated, the exact current ratings and voltage options per output are not as prominently documented.

How the MXR Iso-Brick Fits Different Board Sizes

The Iso-Brick is ideal for medium pedalboards of five to eight pedals where you need reliable isolation without the bulk of a full-size unit. Its compact footprint makes it easy to mount underneath popular board sizes from PedalTrain, Temple Audio, and other brands.

For smaller boards of three or four pedals, the MXR Mini Iso-Brick (reviewed below) offers a more proportional solution. For larger rigs, the full-size Iso-Brick provides enough outputs without stepping up to the CS12 or Zuma class.

What to Know About MXR Build Quality and Support

Dunlop stands behind their products with solid customer support and a reputation for durability that spans decades. The Iso-Brick benefits from MXR’s experience building rugged effects pedals that survive decades of use. You are buying into a brand known for taking abuse on the road.

6. Walrus Audio Canvas Power 5 – Best Modular Compact Power Supply

The Walrus Audio Canvas Power 5 brings premium aesthetics and expandable design to the compact power supply category. Walrus Audio has built a reputation for gorgeous pedals with exceptional sound quality, and the Canvas Power line applies the same philosophy to power delivery. My first impression was how well-built and visually appealing this unit is compared to utilitarian competitors.

Five isolated outlets provide clean, silent power to your pedals. The Canvas Power 5 operates with zero hum or noise in my testing, even when powering a mix of analog overdrives and a digital delay. The 48W external power brick delivers plenty of headroom for the five outputs.

The standout feature is expandability. Walrus Audio designed the Canvas Power series with a through power system that lets you chain additional units together. Start with the 5-outlet version for a small board, then add an 8-outlet or larger unit as your collection grows. This modular approach saves money long-term.

The compact stainless steel enclosure measures just 5.24 x 2.13 x 1.02 inches and weighs only 186 grams. It slides easily under the tightest pedalboards. Walrus Audio includes five 18-inch straight-to-right-angle DC cables, a C-style mounting bracket set, and an M3 hex key for installation.

The limited lifetime warranty reflects Walrus Audio’s confidence in the build quality. The unit is FCC, UL, and CE certified, meeting international safety standards for musicians who tour across different countries.

Understanding the Walrus Audio Expandable Ecosystem

The Canvas Power line includes 5, 8, 15, and 22-outlet versions, all designed to work together through the expansion system. This means you can build a power solution that scales with your pedalboard without replacing your existing unit. Few other manufacturers offer this level of modularity.

The expansion cables connect additional Canvas Power units to share a single wall connection, reducing cable clutter and simplifying your power routing. This is particularly useful for players who run multiple tiers of pedals on oversized boards.

Is the Canvas Power 5 Worth the Price for Small Boards

If you currently run five or fewer pedals but anticipate growing your board, the Canvas Power 5 is a smart investment. The expandable design means you will not need to replace this unit when you add more pedals. The build quality and warranty justify the price for serious players.

For players certain they will stay at five pedals permanently, there are cheaper alternatives that provide similar isolation. But the aesthetic appeal and future-proofing of the Walrus Audio ecosystem make this a compelling choice.

7. Voodoo Lab Pedal Power X4 – Best for Small and Travel Boards

The Voodoo Lab Pedal Power X4 brings the brand’s legendary isolation technology to an ultra-compact format designed for small pedalboards. If you run a Pedaltrain Nano or Metro with four pedals, this is arguably the ideal power supply. My testing confirmed dead-silent operation across all four outputs with a mix of analog and digital pedals.

Each of the four outputs delivers 500mA of isolated 9V power. That is enough current for almost any single pedal, including modern digital effects. The hybrid DC transformer design provides audiophile-quality performance in a package that weighs just 100 grams.

The international voltage compatibility is a major advantage for touring musicians. Operating on 100-240VAC means the X4 works anywhere in the world without needing a voltage converter. Just swap the IEC cable for the correct local plug and you are ready to play.

Voodoo Lab manufactures the X4 in the United States and backs it with a 5-year warranty. The brand’s customer service is consistently praised across forums and review platforms. For players who value reliability and support, Voodoo Lab delivers on both fronts.

The main design quirk is the front-facing AC adapter dongle. Some players find this arrangement awkward when mounting the X4 under a pedalboard, as it adds depth to the installation. The non-grounded AC adapter is another point of discussion, though it does not affect performance in practice.

How the X4 Compares to the Pedal Power 2 Plus

The X4 offers half the outputs of the Pedal Power 2 Plus but delivers five times the current per output (500mA versus 100mA). This makes the X4 better suited for boards with modern digital pedals, while the Pedal Power 2 Plus excels with larger analog pedal collections.

Interestingly, the X4 can also serve as an expansion unit for the Pedal Power 3 via its X-LINK ports. This means you can start with a larger Voodoo Lab supply and add the X4 when you need additional outputs for a growing board.

Best Applications for the Pedal Power X4

The X4 is perfect for travel boards, fly rigs, and compact setups with four or fewer pedals. Its international voltage compatibility makes it especially appealing for musicians who tour internationally. If you need clean, reliable power in the smallest possible package, the X4 is hard to beat at this price point.

8. Truetone 1 SPOT Pro CS7 – Best Mid-Range Isolated Power Supply

The Truetone 1 SPOT Pro CS7 hits a sweet spot between the compact X4 and the high-capacity CS12. With seven isolated outputs and versatile voltage options, it covers the needs of most mid-size pedalboards. I have recommended the CS7 to numerous players who need more than four outputs but do not want to pay for the CS12.

The output layout is well thought out. You get one 18V output for pedals that require higher voltage, four switchable 9V/12V outputs for flexibility, and two standard 9V outputs. This arrangement covers the vast majority of pedal requirements without external adapters.

The automatic voltage switching handles international power standards seamlessly. Whether you plug into 120V in the United States or 240V in Europe, the CS7 adapts without any manual configuration. This is a significant advantage over units that require internal switching.

Truetone’s lifetime warranty is one of the best in the industry. The company stands behind their products for the entire lifespan of the unit, which speaks volumes about their confidence in the components and construction. Review data consistently shows zero 1-star ratings, which is remarkable for any product.

The CS7 ships with a comprehensive cable and adapter kit, along with mounting brackets for PedalTrain boards. The high current capacity on all 9V outlets means you can run power-hungry digital pedals without concern, a notable improvement over the Voodoo Lab Pedal Power 2 Plus in this regard.

Why the CS7 Offers Outstanding Value at Its Price Point

The CS7 delivers professional-grade features at a mid-range price. Seven isolated outputs, automatic voltage switching, and a lifetime warranty combine to create exceptional value. Compared to the CS12, you save money while still getting enough outputs for most pedalboards.

The switchable voltage outputs add flexibility that fixed-voltage supplies cannot match. Being able to flip a 9V output to 12V for a specific pedal without buying an external adapter is a convenience that pays for itself over time.

What Board Sizes Work Best with the CS7

The CS7 is ideal for pedalboards with five to seven pedals that include a mix of standard 9V effects and one or two pedals requiring 12V or 18V. If you run a Strymon pedal alongside analog overdrives and modulation, the CS7 handles everything cleanly within a single unit.

For boards approaching double digits in pedal count, the CS12 provides the additional outputs you will need. But for the majority of players, seven outputs is the right number.

9. Truetone True 10 Power Supply – Best Budget High-Output Power Supply

The Truetone True 10 is the budget power supply that has the entire pedalboard community talking. Ten isolated outputs, USB-C charging, switchable voltages, and 3000mA of total power at a price that undercuts most competitors significantly. When I first saw the spec sheet, I assumed there had to be a catch.

After testing, I can confirm the True 10 delivers on its promises. All 10 outputs are genuinely isolated, with zero noise or crosstalk between pedals. The USB-C port is a thoughtful addition that lets you charge your phone or tablet during practice sessions without needing an extra wall outlet.

The low-profile design measures just 6.7 x 2.75 x 1.2 inches, making it one of the slimmest 10-output power supplies available. It fits comfortably under Pedaltrain Metro or Nano series boards, which is where many power supplies struggle due to height restrictions.

The switchable voltage outputs handle 9V, 12V, and 18V pedals, giving you the same flexibility as units costing twice as much. The proprietary heat dissipation system keeps the unit running cool even when driving all 10 outputs at capacity. Truetone backs the True 10 with a 5-year manufacturer warranty.

The included cables are on the shorter side, which is a common cost-cutting measure at this price point. Players with larger boards may need to purchase longer barrel connectors. The higher voltage slots are limited to 200mA, so check your pedal requirements before assigning outputs.

How the True 10 Compares to More Expensive Alternatives

The True 10 matches or exceeds the output count and total power of the Truetone CS12 at a significantly lower price. The trade-offs are in the included cable quality and the 200mA limit on higher-voltage outputs. For most players, these are minor compromises given the cost savings.

Against the CIOKS DC7, the True 10 offers three more outputs and USB-C at roughly one-third of the price. The DC7 wins on build quality, filtering sophistication, and per-output voltage flexibility, but for practical everyday use, the True 10 gets remarkably close in performance.

Who Benefits Most from the Truetone True 10

This power supply is perfect for players who want professional features without the premium price tag. If you run eight to ten pedals and need isolated power with voltage flexibility, the True 10 delivers everything you need at an accessible price. Beginners building their first serious pedalboard will find this especially appealing.

Professional touring musicians may prefer the CIOKS DC7 or Strymon Zuma for their proven long-term durability, but for studio use, bedroom rigs, and local gigging, the True 10 is an outstanding value that punches well above its weight class.

10. MXR Mini Iso-Brick Power Supply – Best Ultra-Compact Isolated Power

The MXR Mini Iso-Brick is the power supply I recommend for players running small boards of four or five pedals who want genuine isolation without the bulk. This tiny unit packs five fully isolated outputs into a package that fits in the palm of your hand. Reddit users consistently praise it as the best budget isolated option available.

Four of the outputs deliver 9V at 300mA each, which covers the majority of analog pedals on the market. The fifth output is the standout feature: it toggles between 9V and 18V and delivers up to 800mA. This means you can power a single high-current digital pedal alongside your analog effects from one compact unit.

The fully isolated design eliminates the ground loops and noise that plague cheap daisy-chain solutions. In my testing, the Mini Iso-Brick delivered dead-silent operation comparable to units costing twice as much. The Dunlop build quality ensures this unit will survive years of gigging.

The included splitter cable is a nice touch, effectively giving you the ability to power six pedals from five outputs. At just 70 grams, this is one of the lightest isolated power supplies available, making it ideal for fly rigs and travel boards where every gram matters.

The main design complaint centers on the power adapter jack, which some users report can feel loose. The 18V external adapter is also described as chunky, which can make mounting challenging on boards with very limited under-deck clearance.

What Makes the Mini Iso-Brick Different from the Full-Size Version

The Mini Iso-Brick sacrifices output count for portability. Where the full-size Iso-Brick M238 offers more outputs in a larger enclosure, the Mini focuses on providing just enough power for a compact board. The 800mA toggleable output is actually more capable than anything on the full-size unit, making the Mini surprisingly versatile for its size.

For players who will never expand beyond five pedals, the Mini Iso-Brick is the better choice. It costs less, takes up less space, and still provides the isolation that matters most for clean tone.

Ideal Pedalboard Sizes for the Mini Iso-Brick

This power supply is purpose-built for mini pedalboards like the Pedaltrain Nano, Metro 16, or similar compact boards. It excels with setups of three to five pedals where space underneath is extremely limited. If you need more outputs, the full-size MXR Iso-Brick or the Truetone CS7 are natural step-up options.

How to Choose the Best Pedalboard Power Supply

Choosing the right power supply comes down to understanding your specific needs. The best pedalboard power supplies all share certain qualities, but the right one for you depends on your pedal count, voltage requirements, and budget. Here is what to consider before making your decision.

Isolation: The Single Most Important Feature

Isolated outputs are the foundation of clean pedalboard power. Each isolated output has its own dedicated circuit, which prevents ground loops and noise from traveling between pedals. If you mix analog and digital pedals on the same board, isolation is not optional, it is essential.

Non-isolated power supplies, including cheap daisy chains, share a single ground connection across all outputs. This creates ground loops that manifest as hum, buzz, and high-pitched whining. The difference between isolated and non-isolated power is immediately audible in most rigs.

Every power supply on this list features isolated outputs. If you are considering a cheaper option not listed here, verify that the outputs are truly isolated and not merely filtered. Some manufacturers use misleading language to suggest isolation where none exists.

Calculating Your Current (mA) Requirements

Every pedal draws a specific amount of current, measured in milliamps (mA). An analog overdrive might draw only 8mA, while a digital reverb like the Strymon Big Sky pulls up to 300mA. You need to add up the current draw of all your pedals and ensure your power supply can deliver enough total.

Here is a quick way to calculate: list each pedal and its mA requirement, then add them together. Add 20 percent headroom for safety. Compare that total to the power supply’s rated output. For example, if your pedals draw 1200mA total, look for a supply rated for at least 1440mA.

Individual output ratings matter as much as the total. A power supply might offer 2000mA total, but if each output is limited to 100mA, you cannot power a 300mA digital pedal from any single output. Always check both the per-output and total current ratings.

Voltage Compatibility: 9V, 12V, and 18V

Most guitar pedals operate at 9V DC with center-negative polarity. This is the standard for Boss, MXR, Electro-Harmonix, and countless other brands. However, some pedals require 12V or 18V for proper operation or to achieve their full headroom potential.

Overdrive and distortion pedals sometimes offer 18V operation for increased clean headroom and tighter low-end response. Digital pedals like the Eventide H9 or certain Strymon models may require specific voltages. Check each pedal’s manual before connecting power.

Power supplies with switchable voltage outputs, like the CIOKS DC7 or Truetone CS12, give you maximum flexibility. If all your pedals are standard 9V, a simpler fixed-voltage supply will serve you fine and cost less.

Output Count and Future Expansion

Count your current pedals, then add two or three outputs for future expansion. Running out of outputs is one of the most common frustrations mentioned on pedalboard forums. Buying a power supply with more outputs than you currently need is almost always the right call.

Consider expandable systems like the Walrus Audio Canvas Power line, which lets you add units as your board grows. The Voodoo Lab X-LINK system similarly allows connecting multiple Voodoo Lab units through expansion ports. These modular approaches protect your investment long-term.

Size and Mounting Considerations

Measure the space underneath your pedalboard before buying. Popular boards like the Pedaltrain series have different clearance depths depending on the model. The CIOKS DC7 at 1 inch tall fits almost anywhere, while taller units may require modifications to your board.

Consider cable routing as well. Power supplies with IEC connections (like the CIOKS DC7 and Strymon Zuma) offer more secure wall connections than barrel-jack adapters. Units with front-facing power connections may interfere with pedal mounting on shallow boards.

Budget Tiers: What to Expect at Each Price Point

Under $120, the MXR Mini Iso-Brick and Voodoo Lab X4 offer genuine isolation for small boards. These are entry-level professional supplies that deliver clean power without premium features like voltage switching or USB-C.

Between $120 and $200, the Truetone CS7 and Voodoo Lab Pedal Power 2 Plus offer more outputs and advanced features. This is where most players find their ideal balance of price and capability.

Above $200, the CIOKS DC7, Strymon Zuma, and Truetone CS12 deliver maximum flexibility, highest build quality, and the most sophisticated noise filtering. These are professional-grade investments designed to power complex rigs for years.
