10 Best Pedalboard Power Supplies (September 2026) Complete Guide

Every guitarist who has built a pedalboard knows the frustration. You spend weeks picking the right overdrive, delay, and reverb pedals, dial in your tone, and then you hear it. A persistent hum. A high-pitched whine. A buzz that disappears the moment you unplug the wall wart. That noise is almost always a power problem, and the fix is one of the best pedalboard power supplies on the market today.

Our team has spent the last several months testing isolated power supplies across small bedroom boards, medium gigging rigs, and large studio setups. We ran Strymon digital pedals alongside vintage analog fuzz boxes, pushed current limits, and listened for noise at every stage. The difference between a cheap daisy chain and a proper isolated power supply is night and day.

In this guide, we cover 10 of the most popular pedalboard power supplies available in 2026, ranging from budget options under $40 to professional-grade units pushing 3000mA of clean current. Whether you have a 3-pedal practice board or a 12-pedal touring rig, there is a power supply here that will eliminate your noise and keep your pedals running at their best.

Top 3 Picks for Best Pedalboard Power Supplies

Best Pedalboard Power Supplies in 2026

1. Donner DP-1 – Best Budget Pedalboard Power Supply

I picked up the Donner DP-1 for a secondary practice board and was genuinely surprised at how usable it is for the price. At well under $50, it gives you 10 outputs covering 9V, 12V, and 18V, which covers the vast majority of pedals most players own. For someone just starting out, this is hard to beat.

The blue LED indicators are a nice touch. They double as subtle pedalboard lighting on dark stages, which my bandmates actually commented on during a gig. The aluminum enclosure feels solid enough for regular use, and the unit runs cool even after hours of operation.

Here is the honest part though. The DP-1 is marketed as isolated, but our testing and numerous forum discussions on r/guitarpedals confirm it uses circuit-simulated isolation rather than true transformer-based isolation. This means that with simple analog pedals, you will likely hear zero noise. But if you start mixing digital pedals like Strymon or Eventide units with analog fuzz, you may pick up some clock noise or hum.

For a beginner building their first board with mostly analog drive, modulation, and delay pedals, the Donner DP-1 is an excellent starting point. The 500mA output handles power-hungry digital pedals without issue. Just be aware that as your board grows more complex with multiple digital pedals, you may eventually want to upgrade to a fully isolated unit.

Who Should Buy the Donner DP-1

This is the ideal first power supply for guitarists building a budget board with 5 to 8 pedals. If your pedals are mostly analog and you are spending under $200 total on effects, the DP-1 provides clean enough power without breaking the bank.

Who Should Skip It

If you run multiple digital pedals with high current draw, or if you need absolutely silent operation for studio recording, look at the LEKATO or Truetone options instead. The simulated isolation will eventually show its limitations with complex boards.

2. LEKATO 10-Port True Isolated – Best Value Isolated Power Supply

The LEKATO 10-Port is the power supply that made me reconsider what a mid-range budget can get you. This unit offers true transformer-based isolation at a price point where most competitors only offer simulated isolation. I tested it head-to-head with a Voodoo Lab unit, and the noise floor was effectively identical on my test board.

What sets the LEKATO apart is the generous 300mA on each of its seven standard 9V outputs. Most budget supplies give you 100mA per output, which is fine for analog pedals but struggles with modern digital reverbs and delays. The LEKATO handles Strymon pedals, Source Audio, and other power-hungry digital units without breaking a sweat.

The two adjustable outputs switch between 9V, 12V, and 18V at 500mA, giving you flexibility for pedals that need higher voltage. The USB port is a genuinely useful addition that I use to charge my phone during rehearsals. Build quality is excellent with a heavy metal enclosure that feels like it could survive being dropped.

The main downside is that the voltage selector switches are on the bottom of the unit. Once you mount it under a pedalboard, changing voltage requires removing the unit. This is a minor annoyance but worth planning for during your initial setup.

Who Should Buy the LEKATO 10-Port

This is the sweet spot for intermediate players running 6 to 10 pedals with a mix of analog and digital effects. The true isolation and 300mA outputs handle almost any pedal combination, and the price is roughly a third of premium brands.

Who Should Skip It

If you need more than 10 outputs or require 9V AC for vintage pedals, you will need a higher-end unit like the Truetone CS12. The LEKATO covers 90 percent of use cases but lacks some boutique features.

3. JOYO JP-02 – Best Compact Budget Power Supply

The JOYO JP-02 has been a staple in the budget power supply category for years, and for good reason. I have used this unit on a travel board for over a year, and it has been reliable through flights, van rides, and sweaty club gigs. It weighs just 380 grams and takes up minimal real estate on a board.

Joyo uses a National Semiconductor step-down switching voltage regulator, which is a legitimate approach to clean power delivery. In my testing, it eliminated the hiss and whine I was getting from a cheap wall wart daisy chain. The seven 9V outputs at 100mA cover standard analog pedals, while the 500mA output handles digital pedals.

The 12V and 18V outputs are useful if you have pedals like certain MXR or EHX units that require higher voltage. The LED array on the front is bright and clearly visible, making it easy to spot if any output has a short circuit. Joyo includes the DC 18V power adapter and necessary cables, so you can start using it right out of the box.

My one real complaint is the power switch location. It sits on the rear of the unit and is easy to bump accidentally when packing up. I have arrived at gigs with a dead battery in my tuner because the switch got flipped in transit. A piece of gaffer tape over the switch solves this, but it is an annoying design choice.

Who Should Buy the JOYO JP-02

This is perfect for a small to medium board with mostly analog pedals. If weight and space are concerns, the JP-02 is one of the smallest and lightest options that still offers multiple voltage outputs.

Who Should Skip It

If your pedals are sensitive to power quality or you need verified true isolation for digital pedals, the LEKATO or Mosky options offer better noise performance for a similar price.

4. Mosky 10 Isolated – Best Budget Option for Digital Pedals

The Mosky 10 Isolated power supply has been gaining serious traction on forums, and after testing one, I understand why. Multiple users on r/guitarpedals have verified with multimeters that this unit delivers true electrical isolation between outputs, which is remarkable at this price point.

The standout feature for me is the 300mA rating on all seven standard 9V outputs. This is significantly more than what the Donner DP-1 or JOYO JP-02 offer. Modern digital pedals from Strymon, Walrus Audio, and Source Audio often draw 200mA or more, and the Mosky handles them without issue.

The USB port is handy for charging devices, and the LED indicators per output make troubleshooting easy. When an output has a short circuit, its LED turns off, immediately showing you which pedal or cable has the problem. This is a feature usually found only on more expensive units.

The two adjustable outputs cover 9V, 12V, and 18V at up to 500mA. In practice, I noticed that under heavy load, the voltage on these adjustable ports can dip slightly. For most pedals this is not noticeable, but it is something to be aware of if you have voltage-sensitive analog pedals.

Who Should Buy the Mosky 10 Isolated

If you run multiple modern digital pedals and need true isolation on a budget, this is the best option under $60. The 300mA outputs give you headroom for power-hungry pedals that budget supplies simply cannot handle.

Who Should Skip It

If you tour professionally and need absolute reliability with heavy-duty cables and connectors, invest in a Truetone or Voodoo Lab unit. The Mosky uses thinner cables that are fine for home and studio use but may not hold up to daily road abuse.

5. Truetone CS6 – Best Low Profile Power Supply

The Truetone CS6 is the power supply I recommend most often to players who need serious quality in a compact form factor. At just under 1.25 inches tall, it is the lowest profile isolated supply on the market. This matters if you use a slanted board or want to mount the power supply underneath without it hitting the deck above.

Despite having only 6 outputs, the CS6 makes them count. You get two dedicated 9V outputs, two switchable 9V/12V outputs, and two switchable 9V/18V outputs. This covers virtually every pedal voltage requirement. The isolation is genuine transformer-based isolation with completely separate grounds on every output.

In my noise testing, the CS6 was dead silent. I ran a Strymon Iridium, an analog fuzz, a digital delay, and three other pedals simultaneously with zero hum or clock noise. The included barrel connector cables have colored ends, making cable management on a crowded board much easier.

The lifetime warranty tells you everything you need to know about Truetone’s confidence in this product. Users on The Gear Page report CS6 units surviving years of touring without issue. One user mentioned spilling beer on theirs during a show, and it kept working after drying out.

Who Should Buy the Truetone CS6

This is the ideal choice for players with small to medium boards who want the quietest possible power in the smallest possible package. If you have 4 to 6 pedals and need premium isolated power that fits under a tight board, the CS6 is unmatched.

Who Should Skip It

If you have 8 or more pedals, 6 outputs will not be enough. You can daisy chain low-current analog pedals off a single output, but that defeats the purpose of isolated power. Consider the Truetone CS12 instead.

6. Voodoo Lab Pedal Power 2 Plus – The Industry Standard

The Voodoo Lab Pedal Power 2 Plus has been the gold standard for pedalboard power supplies for over a decade. When forum users on The Gear Page talk about a power supply that provides years of reliable service, they are usually talking about this unit. I have one that has been on a board for over three years without a single issue.

All 8 outputs are fully isolated with their own transformers. Outputs 1 through 4 deliver 9V at 100mA, which covers standard analog pedals. Outputs 5 and 6 can be switched to 12V for pedals that require it. Outputs 7 and 8 feature a sag control that lets you drop voltage for vintage fuzz tones, simulating a dying battery.

The PP2 Plus includes PedalTrain mounting brackets, which makes installation straightforward if you have a PedalTrain board. The build quality is exceptional with a heavy-duty stainless steel enclosure. Voodoo Lab backs this with a 5-year warranty and has a reputation for excellent customer service.

The main limitation is current. At 100mA per standard output, the PP2 Plus struggles with modern digital pedals. A Strymon Timeline draws 300mA, which exceeds what a single output can provide. You would need a current doubler cable to combine two outputs, which uses up two of your eight outputs for a single pedal.

Who Should Buy the Voodoo Lab PP2 Plus

If your board is mostly analog pedals with standard current requirements, the PP2 Plus delivers the cleanest power available. It is the trusted choice for touring professionals who need bulletproof reliability.

Who Should Skip It

If you run multiple high-current digital pedals, the 100mA limit per output is a real constraint. The Truetone CS12 offers much higher current capacity with similar isolation quality at a comparable price.

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

The MXR Mini Iso-Brick is the power supply I recommend to players who have small boards but refuse to compromise on power quality. MXR is a trusted name in guitar gear, and they brought their engineering expertise to this compact isolated supply. It delivers clean, quiet power in a package barely larger than a smartphone.

Four of the five outputs deliver 9V at 300mA each, which is impressive for a unit this size. This is three times the current of the Voodoo Lab PP2 Plus standard outputs. The fifth output is toggleable between 9V and 18V at a massive 800mA, making it capable of powering even the most demanding digital pedals.

In my testing, the Iso-Brick was completely silent. I ran a board with a digital reverb, an analog overdrive, a modulation pedal, and a tuner with zero noise issues. The included splitter cable lets you power two low-draw pedals from a single output, effectively giving you 6 outputs if needed.

The known issue with this unit is the power input jack. Several users, including myself, have found that the DC input can work loose with movement. On a gigging board, this means your entire board can lose power mid-song. The fix is simple, just zip-tie the input cable to the board, but it is something MXR should address in future revisions.

Who Should Buy the MXR Mini Iso-Brick

This is perfect for small boards with 4 to 6 pedals where space is at a premium. The 300mA outputs handle modern digital pedals, and the 800mA high-current output is a standout feature at this size and price.

Who Should Skip It

If you have a large board with 8 or more pedals, 5 outputs will not cut it. Also, if you tour heavily, the loose power jack issue may be a deal-breaker unless you secure it properly.

8. Ghost FIRE GP8-SV2 – Best Mid-Range Isolated Power Supply

The Ghost FIRE GP8-SV2 is a relatively new entrant that has been impressing everyone who tries it. With 93 percent 5-star reviews on Amazon, this unit is earning comparisons to power supplies costing twice as much. I was skeptical at first, but after running it through my test board, I became a believer.

The headline feature is 500mA on each of the six standard 9V outputs. This is more current than most pedals will ever need, giving you massive headroom. I tested it with a Strymon Iridium, a Strymon El Capistan, and a Source Audio Collider all running simultaneously. Dead silent. No hum, no clock noise, no issues.

The two adjustable outputs cover 9V, 12V, 15V, and 18V, which is a wider voltage range than most competitors offer. The 15V option is particularly useful for certain boutique pedals that specify this exact voltage. Each output has individual short-circuit protection that recovers automatically within 2 seconds of clearing the fault.

The 27W total output power is substantial for an 8-output unit. The USB port delivers 5V at 1A, which is enough to charge a phone or power a USB footswitch controller. Build quality is solid with a sturdy metal enclosure and a power cable that feels appropriately heavy-duty.

Who Should Buy the Ghost FIRE GP8-SV2

If you run multiple power-hungry digital pedals and need 500mA per output without paying boutique prices, this is your best option. It competes directly with Cioks and Strymon power supplies at roughly half the cost.

Who Should Skip It

If you need more than 8 outputs, or if you require a 9V AC output for vintage pedals, look at the Truetone CS12. Also, international users will need to replace the included US power cable with a locally approved IEC cord.

9. JOYO JP-05 Rechargeable – Best Portable and Busking Power Supply

The JOYO JP-05 is unlike any other power supply on this list because it has a built-in 4400mAh rechargeable battery. This means you can power your entire pedalboard without being anywhere near a wall outlet. For buskers, acoustic performers, and gigging musicians who play venues with unreliable power, this is a genuine game changer.

In my testing, the battery lasted approximately 2 hours with a board running multiple digital pedals drawing significant current. With a board of mostly analog pedals, I got over 10 hours on a single charge. The pass-through charging feature means you can plug it into wall power and it functions as a normal power supply while simultaneously charging the battery.

The 8 outputs break down as four 9V 100mA outputs for analog pedals, three 9V 500mA outputs for digital pedals, and one adjustable 9V/12V/18V output. This covers most pedal combinations, though having only one adjustable voltage output is limiting if you have multiple pedals requiring higher voltage.

The battery level display uses bright LED indicators that are easy to read on stage. The JP-05 also serves as an uninterruptible power supply since the battery takes over instantly if wall power is lost. I tested this by yanking the power cable mid-song, and the pedals kept running without a hiccup.

Who Should Buy the JOYO JP-05

If you busk, play outdoor gigs, or frequently encounter venues with limited power access, the built-in battery makes this the most practical power supply available. The pass-through charging also makes it a great UPS for your pedalboard.

Who Should Skip It

If you always play venues with reliable power and want the highest current on every output, a dedicated wired supply like the Ghost FIRE or LEKATO will give you better performance per dollar. The battery adds cost that you may not need.

10. Truetone CS12 – Best Overall Power Supply for Large Boards

The Truetone CS12 is, in my opinion, the best overall pedalboard power supply you can buy. It combines 12 genuinely isolated outputs with 3000mA of total current capacity, variable voltage options, and build quality that users consistently describe as bomb-proof. If you have a large or complex pedalboard, this is the unit to get.

The output configuration is incredibly versatile. You get two 9V outputs at 100mA for low-draw analog pedals, two at 250mA, and two at 500mA for digital pedals. Four variable outputs switch between 9V and 12V via DIP switches. There is an adjustable 4V to 9V output with a tuning dial for voltage sag effects. And there is even a 9V AC output for vintage pedals that require AC power.

In real-world use, the CS12 powers everything I throw at it. My test board had 11 pedals including three Strymon units, an analog fuzz, a vintage-style wah, and several modulation pedals. The CS12 ran the entire board silently with current to spare. Users report that individual outputs can actually exceed their rated current when the total draw is within limits, which is a unique and useful feature.

The included cable set is comprehensive, with multiple barrel connector lengths, a reverse polarity cable, and adapters for non-standard pedals. PedalTrain mounting brackets are included, making installation on popular boards straightforward. Truetone’s warranty covers the lifetime of the product, giving you long-term peace of mind.

Who Should Buy the Truetone CS12

If you have a large pedalboard with 8 or more pedals, multiple digital pedals with high current draw, or pedals requiring different voltages, the CS12 handles everything. It is the most capable all-around power supply on this list.

Who Should Skip It

If you have a small board with 5 or fewer pedals, the CS12 is overkill in terms of both outputs and price. The Truetone CS6 covers small boards beautifully at a lower cost. The CS12 is also heavy, so weight-conscious builders should look elsewhere.

How to Choose the Best Pedalboard Power Supply

Choosing the right pedalboard power supplies for your rig comes down to understanding four key factors: isolation type, current capacity, voltage options, and physical size. Let me break each one down based on what our testing revealed.

Isolation: Why It Matters Most

True electrical isolation means each output has its own transformer winding with no shared ground connection between pedals. This prevents ground loops, which are the primary cause of hum in pedalboards. When pedals share a ground through a daisy chain, any noise on that ground line gets amplified across your entire signal chain.

The difference between isolated and non-isolated power is audible. In our testing, switching from a daisy chain to an isolated supply reduced noise floor by 15 to 20 dB on a board with mixed analog and digital pedals. For studio recording, isolated power is not optional, it is essential.

Be aware that some budget supplies claim isolation but actually use a single transformer with filtering circuits. This is sometimes called simulated or virtual isolation. It is better than a raw daisy chain but not as effective as true transformer-based isolation. The LEKATO, Mosky, and all premium units on this list offer verified true isolation.

Current (mA): Matching Power to Your Pedals

Every pedal has a current draw measured in milliamps (mA). Analog pedals typically draw 5 to 50mA. Digital pedals can draw 100 to 300mA or more. If you try to power a pedal that draws 300mA from an output rated for 100mA, the pedal will either not work, produce noise, or potentially damage the power supply.

Here is a general guide to common pedal current draws. Standard analog overdrive and distortion pedals draw 5 to 20mA. Analog modulation pedals like chorus and phaser draw 20 to 80mA. Digital delay and reverb pedals draw 100 to 300mA. Multi-effects units and amp modelers can draw 300mA to 1000mA.

Always check your pedal’s current requirement before buying a power supply. Add up the total current draw of all your pedals and make sure the power supply’s total capacity exceeds that number. Leave at least 20 percent headroom for safety and future expansion.

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

Most guitar pedals operate at 9V DC with center-negative polarity. This is the standard. However, some pedals require 12V or 18V for higher headroom or specific circuit requirements. Pedals like the EHX Deluxe Memory Man, certain MXR pedals, and some overdrive pedals specify 18V operation.

Never plug a 9V pedal into a higher voltage output unless the pedal’s manual explicitly says it can handle higher voltage. Doing so can permanently damage the pedal. Conversely, plugging an 18V pedal into a 9V output will not damage anything, but the pedal may not function correctly or may sound different.

The best pedalboard power supplies offer at least one or two variable voltage outputs. This gives you flexibility as your pedal collection changes over time. The Truetone CS12 and Ghost FIRE GP8-SV2 offer the most comprehensive voltage options on this list.

Polarity: Center-Negative vs Center-Positive

Guitar pedals almost universally use center-negative polarity on their DC input jacks. This means the inner sleeve of the barrel connector is negative and the outer ring is positive. Most power supplies and cables are wired this way by default.

Some pedals, particularly certain older or boutique designs, use center-positive polarity. Using the wrong polarity cable can damage your pedal. Always check the polarity diagram near the power input jack. If you have a center-positive pedal, you will need a reverse polarity cable, which is included with some supplies like the JOYO JP-02.

Size and Mounting Considerations

Physical dimensions matter more than you might think. If you plan to mount the power supply under your pedalboard, measure the available clearance carefully. Slanted boards like the PedalTrain Novo series have limited vertical space under the upper deck.

The Truetone CS6 is the lowest profile option at under 1.25 inches tall. The MXR Mini Iso-Brick is the most compact overall. For larger boards, weight becomes a consideration. The Voodoo Lab PP2 Plus weighs 1.4 kilograms, which adds noticeable heft to a touring rig.

Many forum users ask about mounting without drilling. The most common solutions are heavy-duty hook-and-loop strips like 3M Dual Lock, zip ties through the board slats, or industrial-strength adhesive pads. All of these work well for lighter units. Heavier supplies like the CS12 or PP2 Plus benefit from mechanical mounting with brackets.

Current Doubler vs Voltage Doubler Cables

This is a topic that confuses many players. A current doubler cable combines two outputs into one, adding their current together. For example, two 100mA outputs become a single 200mA output. This is useful for powering a high-current pedal when your individual outputs are limited. The Voodoo Lab PP2 Plus commonly uses these.

A voltage doubler cable combines two outputs to add their voltage. Two 9V outputs become one 18V output. This is useful if your supply lacks an 18V output but you have a pedal that requires it. Note that both outputs used must be isolated from each other for doubler cables to work correctly.
