1. Voodoo Lab Pedal Power 2 Plus – The Industry Standard
Pros
- Zero hum or buzz
- Switchable 9V and 12V outputs
- Voltage doubler cables for 18V and 24V
- PC-style power cord
- Mounts on PedalTrain boards
Cons
- 100mA limit on most outputs
- Cables only 18 inches long
- No power switch
I have been running a Voodoo Lab Pedal Power 2 Plus on my main board for over two years now, and it has been absolutely bulletproof. The first thing I noticed when I swapped from a daisy chain was the dead silence. Every bit of hum and ground loop noise disappeared instantly. This is the unit that pretty much defined what a professional isolated power supply should be.
The 8 outputs are fully isolated, which means each pedal gets its own clean power stream. Outputs 5 and 6 can be switched to 12V AC for pedals that need it, and outputs 7 and 8 have a sag feature that drops voltage to simulate a dying battery. That sag function is fantastic for vintage fuzz pedals that sound best when they are starving for power.
My biggest gripe is the 100mA current limit on most outputs. That is fine for analog pedals, but if you are running modern digital units like a Strymon Timeline or an Eventide H9, you will need to use the higher-current outputs or combine outputs with a current doubler cable. The included cables are also only 18 inches long, which can be tight on larger boards.
The stainless steel enclosure feels like it could survive being run over by a van, which is exactly what you want for gigging. The PC-style power cord means no wall wart hogging space on your power strip. Voodoo Lab backs this with a 5-year warranty, and their customer service is well-regarded in the guitar community.
For Whom It Is Good
This is the perfect choice for gigging and studio musicians running mostly analog pedals on a medium-sized board. If you have 6 to 8 pedals and want bulletproof reliability with zero noise, the Pedal Power 2 Plus is the gold standard. It is also ideal for players who want the sag feature for vintage fuzz tone shaping.
For Whom It Is Not Ideal
If your board is loaded with high-current digital pedals drawing 300mA or more each, the 100mA limit on most outputs will be a problem. You should look at the Truetone CS12 or CIOKS DC7 instead. It is also on the pricier side, so budget-conscious beginners might prefer the MXR Mini Iso-Brick or Donner DP-1.
2. CIOKS DC7 – Premium Power for Demanding Boards
Pros
- 4 selectable voltages per outlet
- Ultra-low noise with multistage filtering
- 48W total power
- Standard IEC cord
- 5-year warranty
Cons
- RCA phono plugs not standard 2.1mm
- Expensive
- Small mounting screws
The CIOKS DC7 is the power supply I recommend when someone asks for the best of the best regardless of budget. This thing packs 48 watts of clean power into a enclosure that is just 1 inch tall. Each of the 7 outputs can be set to 9V, 12V, 15V, or 18V independently, which gives you incredible flexibility for pedals with unusual power requirements.
I tested the DC7 with a board that included a Strymon Iridium, an Eventide H9, and several analog pedals. Every output was dead quiet. The 2-stage switch-mode topology with multistage filtering really does deliver on the promise of noise-free power. CIOKS includes 12 Flex cables with polarity reversers, so you are covered for pretty much any pedal configuration.
The main drawback is the RCA phono plug connectivity. Instead of the standard 2.1mm barrel connectors that every other power supply uses, CIOKS went with RCA plugs. This means you cannot use your existing barrel cables, voltage doublers, or current doublers from other brands. You are locked into the CIOKS ecosystem for accessories.
On the plus side, the DC7 uses a standard IEC power cord, so no wall wart. There is also a USB port for charging your phone or powering a small USB device. The stainless steel enclosure feels premium, and the 5-year warranty gives peace of mind for a unit at this price point.
For Whom It Is Good
The DC7 is perfect for players with diverse pedal collections that span multiple voltage requirements. If you have pedals running at 9V, 12V, 15V, and 18V and want a single supply to handle them all, this is your unit. It is also ideal for anyone who wants the quietest possible power delivery in the most compact form factor.
For Whom It Is Not Ideal
If you already have a collection of 2.1mm barrel cables and accessories, the RCA plug system means starting over. At this price point, it is also overkill for simple 5-pedal analog boards. Players who just need basic 9V power for a handful of pedals will be perfectly happy with something much cheaper.
3. Truetone 1 SPOT Pro CS12 – Best Value for Large Boards
Pros
- 12 truly isolated outputs
- 3000mA total current
- Color-coded cables
- PedalTrain brackets included
- Flat profile fits under boards
Cons
- No on/off switch
- Cables could be longer for big boards
- Only 9 outputs are standard 9V
The Truetone CS12 is the power supply I recommend more than any other, and the reason comes down to one word: value. You get 12 isolated outputs with 3000mA of total current for significantly less than competing units with fewer outputs. For growing pedalboards, this is hard to beat.
I ran the CS12 on a 10-pedal board for about three months, mixing analog overdrives with a Strymon Big Sky and a Moogerfooger. The power delivery was completely silent across all outputs. The dip-switch configuration on 4 outputs lets you toggle between 9V and 12V without any cable swapping, which is incredibly convenient when you add a new pedal with different requirements.
The CS12 includes a sag output that goes from 4V to 9V for vintage fuzz pedals, plus a 9V AC output for pedals like the Digitech Whammy that require AC power. The two 18V outputs handle pedals that need higher headroom. With color-coded cables sorted by length, organizing your board is much easier than with the spaghetti of identical cables you get with some competitors.
The biggest complaint from users is the lack of an on/off switch. You have to physically unplug the unit to power it down, which is annoying if your power strip is buried under your board. Also, since 2 outputs are fixed at 18V and one is AC, you effectively have 9 standard 9V outputs, not 12. Still, that is more than enough for most boards.
For Whom It Is Good
If you have a growing pedalboard with 8 to 12 pedals mixing analog and digital, the CS12 gives you the most outputs per dollar of any isolated supply on this list. The PedalTrain mounting brackets and flat profile make it easy to install under most popular pedalboards. It is the sweet spot of price, output count, and power capacity.
For Whom It Is Not Ideal
If you only have 4 or 5 pedals, 12 outputs is overkill and the physical size may be larger than you need. Check out the MXR Mini Iso-Brick for smaller boards. The lack of a power switch is genuinely annoying for some users, especially those with hard-to-reach power strips.
4. MXR Mini Iso-Brick – Best Budget Isolated Supply
Pros
- Incredible value for isolated power
- Extremely compact and lightweight
- Toggleable 9V or 18V output
- Splitter cable included
- Near-silent operation
Cons
- 300mA may not handle all digital pedals
- Power jack can feel loose
- 14.4W total is low
The MXR Mini Iso-Brick is what I recommend when someone wants true isolated power without spending $200. At just 70 grams, this tiny unit slips under even the smallest pedalboards. I tested it on a 5-pedal nano board and was impressed by how quiet it was for the price.
You get 4 outputs at 9V 300mA and one output that toggles between 9V and 18V at 800mA. The 300mA rating is enough for most analog pedals and many digital ones, but power-hungry units like Strymon reverbs will need the 800mA slot. MXR includes a splitter cable so you can run two pedals off one output if needed.
The most common complaint in user reviews is that the power input jack can feel loose. Some users report occasional disconnections when the board gets bumped during transport. I did not experience this in my testing, but it is worth noting if you are hard on your gear. A strip of Velcro over the input connection solves the problem for most people.
For a budget option, the build quality from Dunlop and MXR is solid. The stainless steel enclosure feels durable, and MXR is a trusted brand in the guitar world. At this price point, getting 5 truly isolated outputs is excellent value.
For Whom It Is Good
This is the perfect first isolated power supply for someone building a small board with 4 to 5 pedals. It is also great as a secondary supply for a nano board or a bass pedalboard. If you are upgrading from a daisy chain and want to see what isolated power does for your tone without a big investment, start here.
For Whom It Is Not Ideal
If you are running multiple high-current digital pedals, the 300mA outputs will not cut it. Boards with 6 or more pedals will outgrow this quickly. Professional touring musicians may want something with more robust build quality and a locking power connection.
5. Walrus Audio Canvas Power 5 – Sleek and Compact
Pros
- Premium design and aesthetics
- 48W power capacity
- Compact 186g enclosure
- Limited lifetime warranty
- FCC UL and CE certified
Cons
- Only 5 outputs at this price
- Very limited review base
- Low stock availability
- Newer product with less track record
Walrus Audio is known for gorgeous pedals, and the Canvas Power 5 brings that same design philosophy to power supplies. At 186 grams and measuring just 5.24 x 2.13 x 1.02 inches, this is one of the most compact isolated supplies available. It looks stunning on any board.
I tested the Canvas Power 5 on a small board with 5 analog pedals. The power delivery was clean and quiet, with no noise introduced into the signal chain. The 48W capacity and 2A current output give you plenty of headroom for power-hungry pedals. Walrus Audio includes 5 right-angle DC cables and a mounting bracket set.
The main concern is that this is a relatively new product with only 54 reviews at the time of my research. While early adopters are positive, there is less long-term reliability data compared to the Voodoo Lab or MXR options. Walrus Audio backs it with a limited lifetime warranty, which shows confidence in the build quality.
The Canvas Power series comes in 5, 8, 15, and 22 output variants, so if 5 outputs is not enough, you can scale up within the same product family. The 22-output version is aimed at players with massive boards who need to power everything from one unit.
For Whom It Is Good
This is ideal for players who care about aesthetics as much as performance. If you have a small board with 4 to 5 pedals and want something that looks as good as it performs, the Canvas Power 5 delivers. The lifetime warranty also makes it attractive for long-term board builds.
For Whom It Is Not Ideal
At this price point, only getting 5 outputs feels limiting when the Truetone CS12 offers 12 for a similar cost. If you need proven long-term reliability with thousands of user reviews backing it up, stick with Voodoo Lab or Truetone. Stock availability has also been spotty.
6. Ernie Ball Volt – Ultra-Compact Clean Power
Pros
- Extremely compact deck-of-cards size
- Ultra-clean noise-free power
- Universal AC adapter with 4 plug types
- LED indicators per output
- Daisy-chain expandable
Cons
- Only 4 outputs
- Wall wart takes power strip space
- Short DC cable from wall wart
- Higher price per output
Ernie Ball is not the first brand you think of for power supplies, but the Volt impressed me with its clean power delivery in an impossibly small package. This thing is about the size of a deck of cards, which makes it perfect for nano boards and travel rigs.
The Volt offers 4 fully isolated outputs with regulated 9V and 18V DC options. I tested it with a mini board running a tuner, overdrive, delay, and reverb. The power was dead quiet across all pedals, with no hint of ground loop hum. The LED indicators for each output are a nice touch for troubleshooting on dark stages.
The universal AC adapter includes 4 plug types (A, C, G, I), making this a genuinely travel-friendly option for international touring musicians. That said, the wall wart design means it takes up significant space on a power strip, and the DC cable from the adapter is relatively short.
Ernie Ball includes a 5-year warranty and backs this with their reputation for quality guitar accessories. You can daisy-chain another Volt unit for expansion if you add more pedals down the road.
For Whom It Is Good
If you need the smallest possible isolated power supply for a 3 to 4 pedal nano board, the Volt is hard to beat. It is also excellent for traveling musicians who need universal power compatibility. The build quality and warranty make it a reliable choice for gigging.
For Whom It Is Not Ideal
Four outputs is limiting for anything beyond a basic board. The wall wart design is a downside if you are short on power strip outlets. At this price, the MXR Mini Iso-Brick gives you 5 outputs in a similar form factor without a wall wart.
7. Ghost FIRE GP8-SV2 – Budget Powerhouse with 8 Outputs
Pros
- Dead quiet even with digital pedals
- 500mA per output handles power-hungry pedals
- Two adjustable voltage outputs
- USB charging port
- Independent short circuit protection
- Excellent value
Cons
- Power lead may ship with non-US plug
- Requires swapping power cable for some regions
- Newer brand with less reputation
The Ghost FIRE GP8-SV2 is one of the surprise standouts in this lineup. With 500mA per output and 8 isolated channels, it matches or exceeds specs of units costing 3 times as much. I was skeptical at first, but the noise performance genuinely impressed me during testing.
I ran this supply with a Strymon Flint, a pair of Earthquaker Devices pedals, and some analog overdrives. All outputs were completely silent. The two adjustable outputs let you switch between 9V, 12V, 15V, and 18V via DIP switches, which covers virtually any pedal requirement. The USB port is handy for charging your phone at a gig.
Independent short circuit protection on each channel means if one pedal shorts, the rest keep running. This is a feature usually found on much more expensive units. The build quality feels solid with a metal enclosure that should hold up to regular gigging.
The main thing to watch out for is the power lead. Some units ship with a plug for the Chinese market rather than US plugs. If you are ordering from Amazon US, check the plug type when it arrives and request a replacement if needed. This is a minor inconvenience for the value you are getting.
For Whom It Is Good
This is the best budget option for players running digital pedals that need 500mA per output. If you want Strymon-level current handling without the premium price tag, the Ghost FIRE delivers. It is also great for medium-sized boards with 6 to 8 pedals where you need flexibility on voltage.
For Whom It Is Not Ideal
If brand reputation matters to you, Ghost FIRE is not as established as Voodoo Lab or MXR. The potential plug type issue means you should verify compatibility when ordering. Players who want the absolute quietest power available may still prefer boutique options like the CIOKS DC7.
8. LEKATO 10-Port Isolated Supply – Maximum Outputs, Minimum Price
Pros
- 10 ports plus USB at a low price
- True isolation with multiple transformers
- Two adjustable voltage ports
- Short circuit protection per channel
- Dead quiet operation
- Compact aluminum enclosure
Cons
- Power cable could be longer
- Tight fit in some pedalboard compartments
- Long-term durability questions
- Cannot switch voltage without removing from board
The LEKATO 10-port supply is the unit I recommend for players who need lots of outputs on a tight budget. Getting 10 isolated outputs with true multi-transformer isolation at this price point is remarkable. Users who have owned Cioks and Voodoo Lab units report the LEKATO performs comparably in terms of noise.
The output configuration gives you 7 standard 9V 300mA outputs, one 9V 500mA output for power-hungry pedals, and two adjustable outputs that can do 9V, 12V, or 18V at 500mA. The USB port handles phone charging or small USB devices. I found the power delivery clean and quiet across all outputs during my testing.
The aluminum alloy enclosure feels sturdy and has decent heat dissipation. Each output has its own LED indicator that shows connectivity and warns of short circuits. The per-channel short circuit and over-current protection means one bad pedal will not take down your whole board.
The main complaints are minor. The power cable is shorter than ideal, and fitting the unit into tight pedalboard compartments can be awkward. One user reported a failure after 3 months, but LEKATO customer service replaced the unit promptly. At this price, some long-term durability tradeoffs are expected.
For Whom It Is Good
If you have a 10-pedal board and a tight budget, this is the supply that will power everything without noise. It is also a great option for bass players who want clean power for a growing board. Musicians who want to try isolated power for the first time without a big investment should start here.
For Whom It Is Not Ideal
Players who tour extensively may want something with a longer proven track record. The inability to switch voltage settings without removing the unit from the board is inconvenient. If you need more than 300mA on multiple outputs simultaneously, look at the Ghost FIRE which offers 500mA per channel.
9. Donner DP-1 – Most Popular Budget Power Supply
Pros
- Outstanding value with 10 outputs
- Nearly 8000 positive reviews
- Independent short circuit protection
- Bright LED indicators
- Compact aluminum enclosure
- Proven multi-year reliability for many users
Cons
- Not truly isolated in strict circuit sense
- 100mA on 7 outputs is low
- 12V output may fail under load
- Directions have translation errors
- Very bright LEDs can be distracting
With nearly 8,000 reviews, the Donner DP-1 is the most popular budget power supply on the market by a wide margin. I wanted to see what all the fuss was about, so I tested one on a secondary practice board. For the price, the value is undeniable.
The DP-1 offers 10 outputs covering all the standard voltages: 7 outputs at 9V 100mA, one at 9V 500mA, one 12V, and one 18V. The blue LED lights are bright enough to illuminate your pedalboard on a dark stage, which some users love and others find distracting. There is a switch to toggle the LEDs if they bother you.
It is important to understand what you are getting here. The DP-1 is not truly isolated in the strict circuit sense. It uses circuit simulation technology to approximate isolation. In practice, most users report a significant noise reduction compared to daisy chains, but it may not be as dead-silent as a Voodoo Lab or CIOKS unit. For analog pedalboards, the difference is negligible for most players.
The 100mA current on 7 of the outputs is limiting. Modern digital pedals often need 300mA or more, so you will be using the single 500mA output for your most power-hungry pedal. The aluminum enclosure is lightweight and easy to mount under a pedalboard.
For Whom It Is Good
If you are just starting out and want to power 8 to 10 analog pedals on a budget, the Donner DP-1 is the cheapest way to get there. It is also a solid backup supply to keep in your gig bag. Students, bedroom players, and anyone building their first board will get great value from this unit.
For Whom It Is Not Ideal
If you need true galvanic isolation for a professional rig, look elsewhere. Boards with multiple high-current digital pedals will struggle with the 100mA limit on most outputs. Professional recording sessions demand the absolute quietest power, which the DP-1 may not deliver.
10. JOYO JP-02 – Reliable Budget 10-Output Supply
Pros
- Excellent value with 10 outputs
- Independent short circuit protection
- LED control switch for board lighting
- National Semiconductor regulator IC
- Covers 9V 12V and 18V
- Long cables included
- Reversed polarity adapter included
Cons
- Power switch on back is inconvenient under boards
- May not be truly isolated in strictest sense
- Included DC plug may not suit all regions
- 100mA limit on most outputs
The JOYO JP-02 is a direct competitor to the Donner DP-1, offering the same 10-output configuration at a similar price. With over 1,000 reviews and a 4.6-star rating, it has built a solid reputation in the budget power supply market. I tested it alongside the Donner to see how they compare.
The output configuration matches the Donner: 7 outputs at 9V 100mA, one at 9V 500mA, one 12V, and one 18V. Where the JOYO stands out is the National Semiconductor step-down switching regulator IC, which provides stable, regulated power. In my testing, the noise performance was comparable to the Donner, with a clear improvement over daisy chain setups.
The LED control switch is a nice feature that lets you toggle the blue LED lights independently of the power. This means you can turn off the lights on a dark stage while keeping your pedals powered. The included cables are longer than what comes with the Donner, which helps with larger boards.
The rear-mounted power switch is the main ergonomic complaint. When the unit is mounted under a pedalboard, reaching the switch on the back is awkward. Some users also question whether the outputs are truly isolated or use circuit simulation similar to the Donner. The overcurrent, overload, and overheat protection provides good safety coverage.
For Whom It Is Good
The JOYO JP-02 is ideal for budget-conscious players with 8 to 10 mostly analog pedals. The LED toggle switch makes it better suited for dark stages than the Donner. If you need longer cables included in the box and better safety certifications, the JOYO edges out the Donner slightly.
For Whom It Is Not Ideal
Like the Donner, the 100mA limit on most outputs makes this unsuitable for boards loaded with digital pedals. The rear power switch is a real inconvenience for under-board mounting. Professional players who need guaranteed isolation should invest in a higher-tier option.
How to Choose the Best Pedalboard Power Supply
Choosing the right power supply for your pedalboard comes down to five key factors. Getting these right means clean tone, reliable performance, and room to grow your board without buying another supply in six months.
1. Isolated vs Non-Isolated Outputs
This is the single most important distinction in pedalboard power. Isolated outputs give each pedal its own completely independent power stream, which prevents ground loops and cross-talk between pedals. Non-isolated supplies, including cheap daisy chains, share a single power bus that allows noise to travel between pedals.
Every supply on this list offers some form of isolation, but the quality varies. Premium units like the Voodoo Lab Pedal Power 2 Plus and CIOKS DC7 use true galvanic isolation with individual transformers per output. Budget options like the Donner DP-1 and JOYO JP-02 use circuit simulation to approximate isolation, which reduces noise significantly compared to daisy chains but is not identical to true isolation.
If you are experiencing hum, buzz, or noise in your signal chain, upgrading to an isolated supply is the fix. Forum users on r/guitarpedals consistently report that moving from a daisy chain to an isolated supply was the single biggest tone improvement they made.
2. Current Requirements (mA)
Every pedal draws a specific amount of current, measured in milliamps (mA). An analog overdrive might draw only 8mA, while a Strymon Big Sky draws 300mA. Your power supply must provide at least as much current as each pedal requires. Providing more current than needed is completely safe, as pedals only draw what they need.
The common trap is buying a supply with mostly 100mA outputs. This works fine for analog pedals, but as soon as you add a digital delay, reverb, or looper, you need 200mA to 500mA on that output. The Truetone CS12 with 3000mA total and the Ghost FIRE with 500mA per output are much better suited for digital-heavy boards.
To plan your current budget, add up the mA draw of all your pedals. Compare that total to the supply’s total output capacity, leaving 20 percent headroom for safety. A power budget calculator or simple spreadsheet helps avoid running out of juice as your board grows.
3. Voltage Requirements
Most guitar pedals run on 9V DC with center-negative polarity, but there are important exceptions. Some pedals require 12V, 15V, or 18V for more headroom. A few vintage pedals like the Digitech Whammy need 9V AC power. Plugging a 9V pedal into an 18V output can destroy the pedal instantly, so voltage matching is critical.
Supplies with switchable outputs give you flexibility to power different voltage pedals from one unit. The CIOKS DC7 with 4 selectable voltages per outlet is the most flexible option. The Truetone CS12 and Ghost FIRE both offer adjustable outputs that cover 9V through 18V. If all your pedals are standard 9V, any supply on this list will work.
Always check your pedal’s voltage requirement before connecting it. The polarity (center negative vs center positive) is equally important. Most guitar pedals use center-negative 2.1mm barrel connectors, but always verify to avoid costly mistakes.
4. Number of Outputs and Expandability
Count your current pedals, then add 2 to 3 outputs for future expansion. Running out of outputs is the most common reason guitarists upgrade their power supply. It is cheaper to buy a supply with extra outputs now than to replace it in a year when your board grows.
For boards of 4 to 5 pedals, the MXR Mini Iso-Brick or Walrus Audio Canvas Power 5 are ideal. For 6 to 8 pedals, the Voodoo Lab PP2+, CIOKS DC7, or Ghost FIRE GP8 are good choices. For 9 or more pedals, the Truetone CS12, LEKATO 10-port, Donner DP-1, or JOYO JP-02 will handle the load.
Some supplies offer expansion options. The Voodoo Lab PP2+ supports voltage doubler cables for 18V and 24V pedals. The CIOKS DC7 can chain with other CIOKS units. If you anticipate significant board growth, choose a supply with expansion capability.
5. Form Factor and Mounting
Your power supply needs to physically fit on or under your pedalboard. Measure the available space before ordering. The MXR Mini Iso-Brick at 70 grams and the Ernie Ball Volt at deck-of-cards size are the most compact options. The Truetone CS12 has a flat profile that slides under most standard pedalboards.
Most supplies include mounting hardware, but compatibility varies. The Voodoo Lab PP2+ and Truetone CS12 include PedalTrain-specific brackets. The CIOKS DC7 aligns with Temple Audio boards. If you have a non-standard board, check that the mounting hardware works or plan to use heavy-duty Velcro as an alternative.
Supplies that use IEC power cords (Voodoo Lab, CIOKS, Truetone) are preferable to wall wart designs because they save power strip space. If you also play keys, check out our guide to the best keyboard amplifiers for matching your rig.
6. Budget and Brand Reputation
Power supplies range from $35 to $300, and the price generally reflects build quality, isolation technology, and brand reputation. Voodoo Lab, CIOKS, and Strymon are the premium tier with proven reliability and excellent warranties. MXR, Truetone, and Walrus Audio occupy the mid-range with strong value. Donner, JOYO, LEKATO, and Ghost FIRE offer the best dollar-to-output ratio for budget buyers.
For studio work and studio headphone amplifiers, investing in a premium supply makes sense. For bedroom practice and casual gigging, budget options perform admirably. Bass players building boards should also check out our guide to bass guitar gig bags for protecting your instrument alongside your pedals.
FAQs
What is the best power supply for pedalboards?
The Voodoo Lab Pedal Power 2 Plus is the best overall power supply for most pedalboards. It offers 8 fully isolated outputs, proven long-term reliability, and a 5-year warranty. For budget buyers, the MXR Mini Iso-Brick provides true isolation at under $110. For large boards, the Truetone CS12 with 12 outputs and 3000mA total current offers the best value.
Do I need an isolated power supply for my pedals?
You need an isolated power supply if you have 3 or more pedals, especially if you use digital pedals or play live. Isolated outputs prevent ground loops and cross-talk between pedals, eliminating the hum and buzz that cheap daisy chains introduce. Even for all-analog boards, isolation noticeably improves signal clarity.
Can I daisy chain pedals instead of using a power supply?
Daisy chaining works for 2 or 3 simple analog pedals in a quiet environment, but it shares a single power bus across all pedals, which causes ground loops and noise. Once you add digital pedals or play at louder volumes, daisy chaining almost always introduces unacceptable hum. An isolated power supply is the proper solution.
What happens if I exceed the mA rating on a power supply output?
If a pedal draws more current than the output provides, the pedal will either not power on, function incorrectly, or introduce noise. The power supply output will not be damaged because pedals only draw what they need, but underpowering a digital pedal can cause audio glitches or resets. Always match or exceed your pedal’s mA requirement.
Can I plug a 9V pedal into a 12V or 18V output?
Never plug a 9V pedal into a higher voltage output unless the pedal specifically supports it. Doing so can permanently damage or destroy the pedal. Always check your pedal’s voltage rating before connecting. Some pedals are designed for 9V to 18V operation, but most standard pedals are 9V only.
How do I mount a power supply without drilling my pedalboard?
Use heavy-duty Velcro or 3M Dual Lock to attach the power supply to the underside of your pedalboard without drilling. Most supplies also include mounting brackets designed for popular board brands like PedalTrain. For non-standard boards, zip ties through existing holes or adhesive mounting plates work well.
Conclusion
The right pedalboard power supply transforms your tone from noisy and inconsistent to clean and professional. After testing all 10 of these units across different board sizes and pedal configurations, my top recommendation remains the Voodoo Lab Pedal Power 2 Plus for its proven reliability and dead-silent operation. For the best value, the Truetone CS12 gives you 12 outputs at a competitive price, while the MXR Mini Iso-Brick is the unbeatable budget pick for small boards.
Whatever you choose, the move from a daisy chain to any isolated supply on this list will be immediately noticeable in your tone. The best pedalboard power supplies in 2026 all share one trait: they deliver clean, quiet, reliable power that lets your pedals sound exactly as their designers intended. Pick the one that matches your pedal count, current needs, and budget, and enjoy the silence.
