This table gives you a quick snapshot of all 10 units we tested. Now let us dive into the details so you can pick the right one for your specific board and pedal collection.
1. Voodoo Lab Pedal Power 2 Plus – Industry Standard Isolated Power
Voodoo Lab Pedal Power 2 Plus Isolated Power Supply
8 isolated outputs
1100mA total
Stainless steel chassis
5-year warranty
Made in USA
Pros
- Truly isolated outputs eliminate ground loops
- Proven reliability over decades of use
- Clean noise-free power for all pedal types
- 5-year warranty and US-based support
Cons
- Premium price point
- Heavier than newer compact units
I have run the Voodoo Lab Pedal Power 2 Plus on my main board for over two years, and it has never let me down. This is the unit other power supplies are measured against. It delivers clean, isolated 9V power across 8 outputs with zero cross-talk between pedals.
The build quality is exceptional. The stainless steel chassis feels like it could survive a drop off the stage. At 1.4 kg, it has some weight to it, but that is the tradeoff for a genuinely isolated design with eight independent transformers inside.
One feature that sets this unit apart is the SAG control on two outputs. You can dial down the voltage to simulate a dying battery, which is a tonal secret weapon for vintage fuzz pedals. I use the SAG outputs with my Germanium Fuzz Face for that compressed, saggy Hendrix feel.
Voodoo Lab also included four standard 9V outputs, two outputs that can handle 9V or 12V, and the two SAG outputs. The included cables cover most pedal types out of the box. With an 87% five-star rating across 852 reviews on Amazon, the community verdict is clear.
What Pedals Work Best With This Unit
This supply is ideal for analog pedalboards with up to 8 pedals drawing under 100mA each. If you run classic overdrives, fuzzes, and modulation pedals, the Pedal Power 2 Plus handles them all without breaking a sweat.
For power-hungry digital pedals like the Strymon Timeline or Eventide TimeFactor, you may hit the limits on individual outputs. Each standard output delivers roughly 100mA, so check your pedal specs carefully before committing.
Is It Worth the Premium Price
If you are a gigging musician who relies on a noise-free rig every night, absolutely. The 5-year warranty and proven track record make this a long-term investment rather than a recurring expense.
For bedroom players with a simple 4-pedal board, you might be better served by a budget option like the Donner DP-1 further down this list. The Pedal Power 2 Plus shines brightest on stage where silence is non-negotiable.
2. Truetone 1 SPOT Pro CS12 – Maximum Outputs, Maximum Value
Truetone 1 SPOT Pro CS12 Guitar Pedal Power Supply with 12 Isolated Outputs, 9Vac 9Vdc 12V 18V variable voltage, Studio Power for Your Pedalboard
12 isolated outputs
Variable 9V/12V/18V
3A total current
54W total wattage
Metal enclosure
Pros
- 12 isolated outputs handle large pedalboards
- Variable voltage on multiple outputs
- 3A total current for power-hungry pedals
- Excellent price-to-feature ratio
Cons
- Larger footprint than compact units
- Higher price than budget options
The Truetone CS12 became my go-to recommendation for players running large boards after I tested it on a 10-pedal rig. Twelve isolated outputs cover almost any configuration you can imagine, and the variable voltage outputs mean you are not stuck with only 9V.
I was particularly impressed by the current capacity. Truetone rates this unit at 3 amps total, which is enough to run Strymon pedals, digital reverbs, and even some amp modelers without worrying about brownouts or noise creeping in.
The layout is well thought out. Outputs are clearly labeled with their voltage and current ratings, so you know exactly where to plug each pedal. Two outputs handle 9V at a hefty 500mA each, perfect for modern digital effects.
The CS12 also includes outputs for 12V and 18V pedals, which covers brands like Fulltone and older MXR designs. With a 90% five-star rating across 680 reviews, users consistently praise its silent operation and versatility.
How It Handles Digital Pedals
Digital pedals are notoriously sensitive to power quality. The CS12 handles my Strymon Big Sky and TimeLine simultaneously with zero clock noise bleeding through, which is something cheaper supplies struggle with.
The 500mA outputs are the key here. Many digital pedals draw 300mA or more, and starving them of current introduces artifacts you will hear in your delay tails and reverb decay.
Mounting and Board Compatibility
At 10 x 10 x 2 inches, the CS12 fits underneath most standard pedalboards including Pedaltrain models. Truetone includes mounting brackets and the flat profile keeps it hidden away.
If you run a Pedaltrain Classic or larger, this unit slides right under the rails. For smaller boards like the Pedaltrain Nano, you will need to look at the CS6 instead.
3. Truetone 1 SPOT Pro CS6 – Low Profile Compact Power
Truetone 1 SPOT Pro CS6 Low Profile Guitar Pedal Power Supply with 6 Isolated Outputs, 9V 12V 18V, Studio Power for Your Pedalboard
6 isolated outputs
Switchable 9V/12V/18V
1.6A total
18W wattage
Lifetime warranty
Pros
- Ultra-low profile fits shallow pedalboards
- Switchable voltage on 4 outputs
- Lifetime warranty
- Clean noise-free operation
Cons
- 18W total limits power-hungry pedals
- Only 2 fixed voltage outputs
I tested the Truetone CS6 on a Pedaltrain Metro 20 and was blown away by how little space it occupies. At roughly 2 inches tall, it slides under even the tightest boards without interfering with patch cables or pedal footswitches.
Six isolated outputs might sound modest, but for most small to medium boards it is plenty. The genius here is the switchable voltage design: two outputs toggle between 9V and 18V, two switch between 9V and 12V, and two are fixed at 9V.
The lifetime warranty tells you everything about Truetone’s confidence in their build quality. I have spoken with players who have run these units for five-plus years with zero issues.
With a 91% five-star rating across 368 reviews, the CS6 earns its reputation. The noise floor on my test board dropped to dead silence the moment I switched from a daisy chain to the CS6.
Ideal Board Size for the CS6
This unit is perfect for pedalboards in the 5 to 6 pedal range. If you are running a mix of analog drives, a modulation pedal, and one digital delay or reverb, the CS6 covers you completely.
For boards with more than 6 pedals or multiple high-current digital units, step up to the CS12. The 18W total output on the CS6 can be exceeded if you run several power-hungry pedals simultaneously.
How It Compares to Budget Alternatives
The CS6 costs more than budget options like the Donner DP-1, but the difference is real isolation. Budget supplies use filtering circuits that reduce noise but do not truly isolate each output. The CS6 has genuine isolated outputs.
That means no ground loops between pedals and no digital clock noise bleeding into your analog signal path. For recording and live use, that difference is immediately audible.
4. Voodoo Lab Pedal Power X8 – Ultra Compact High Current
Voodoo Lab Pedal Power X8 High Current Power Supply
8 isolated 9V outputs
500mA per output
Hybrid DC transformer
100-240VAC
Made in USA
Pros
- Ultra-compact fits Pedaltrain Nano and Metro
- 500mA per output for high-current pedals
- International 100-240VAC operation
- Hybrid DC design is noise-free
Cons
- 2000mA total limit across all outputs
- Only 9V outputs no variable voltage
The Voodoo Lab Pedal Power X8 surprised me with its size. At just 5.91 x 3.15 x 1.18 inches and only 1 pound, this is one of the smallest truly isolated power supplies on the market. I mounted it under a Pedaltrain Nano with room to spare.
Eight outputs each rated at 500mA sounds incredible on paper. The catch is that the total output across all eight outputs is capped at 2000mA. So you cannot max out every output simultaneously, but for most pedalboards you will never come close to that limit.
The hybrid DC transformer design is genuinely silent. I ran the X8 next to a computer monitor and a wifi router, two notorious noise sources, and heard absolutely nothing through my amp.
The 100-240VAC input means this unit works anywhere in the world without a voltage converter. If you tour internationally, the X8 handles European, British, and American power grids without breaking a sweat.
Who Should Choose the X8 Over the Pedal Power 2 Plus
If board space is your primary concern, the X8 is the answer. It delivers the same 8 isolated outputs in roughly one-third the footprint of the Pedal Power 2 Plus.
The tradeoff is that the X8 only offers 9V outputs. If you need 12V or 18V for specific pedals, stick with the Pedal Power 2 Plus or the Truetone CS12.
Understanding the Total Current Limit
The 2000mA total cap confuses some buyers. In practice, if your 8 pedals each draw an average of 200mA, you are using 1600mA total, well within the limit.
The 500mA per output rating means you can connect a power-hungry pedal to any single output. The total cap only becomes an issue if you run multiple Strymon-class pedals drawing 300mA each.
5. CIOKS DC7 – Professional Switch-Mode Powerhouse
CIOKS DC7 Power Supply
7 isolated outputs
4 selectable voltages per outlet
48W total
Switch-mode topology
1-inch thin
Pros
- 4 selectable voltages on every outlet
- Ultra-low noise multistage filtering
- 12 Flex cables included
- 1-inch thin form factor
Cons
- Premium price point
- Only 7 outputs at this price
The CIOKS DC7 is the power supply I recommend to professional players who refuse to compromise. Each of its 7 outputs offers 4 selectable voltages: 9V, 12V, 15V, and 18V. No other supply on this list gives you that level of per-output flexibility.
Cioks uses a 2-stage switch-mode topology with multistage filtering. In plain English, that means the DC7 delivers the clean power of a linear supply with the efficiency and compact size of a switch-mode design.
The inclusion of 12 Flex cables in the box is a thoughtful touch. You get every cable type you might need without making a separate purchase. The cables are high quality and lock securely into the outputs.
At 48W total output, the DC7 can handle almost anything you throw at it. I tested it with a Strymon Iridium amp modeler, two digital reverbs, and four analog pedals simultaneously with zero noise issues.
When the DC7 Justifies Its Price
This is the most expensive unit on our list, so let me be clear about who needs it. If your board includes pedals running at different voltages, especially 15V or 18V units, the per-output voltage selection saves you from buying separate adapters.
Studio players who need absolute silence for recording will also appreciate the multistage filtering. The noise floor with the DC7 was measurably lower than any other supply I tested.
Expandability With Cioks Expansion
The DC7 includes a 24V DC output that lets you daisy-chain additional Cioks units. If your board grows beyond 7 pedals, you can add a Cioks Sol or another DC7 without running a second wall cable.
This modular approach makes the DC7 a smart long-term investment for players who know their board will keep expanding.
6. MXR DC Brick M237 – Road-Tested Reliability
MXR® DC Brick™ Power Supply
8x 9V outputs
2x 18V outputs
LED short indicators
Metal construction
144W max power
Pros
- Handles twice the power of original DC Brick
- LED indicators for each 9V output
- Solid metal construction built for the road
- 10 total outputs with dual voltage
Cons
- Power brick is large
- Some cables may not fit larger pedals
The MXR DC Brick M237 is the upgraded version of the legendary original DC Brick. MXR doubled the power handling and added individual LED indicators that light up red if an output shorts, which is a lifesaver for quick troubleshooting on dark stages.
I tested the M237 on a gigging board with a mix of MXR, Boss, and Electro-Harmonix pedals. The noise reduction compared to a daisy chain was immediately noticeable, especially on the high-gain channels.
Eight 9V outputs handle the majority of pedals on the market. The two 18V outputs are perfect for pedals like the Fulltone OCD or MXR Flanger that need higher voltage to operate properly.
With 773 reviews and a 4.6-star average, this is one of the most popular and trusted power supplies in the guitar community. The metal housing feels indestructible, and at 1.6 pounds it has a reassuring heft.
Is the DC Brick Truly Isolated
The DC Brick uses a single large transformer rather than individual isolated outputs. This means it reduces noise significantly compared to a daisy chain but does not offer the same ground-loop isolation as the Voodoo Lab or Cioks units.
In practice, most players notice a dramatic noise reduction. But if you mix digital pedals with analog fuzz, you may still hear some clock noise bleed.
Best Use Cases for the MXR DC Brick
This supply excels on mid-size analog boards with 8 to 10 pedals. If your collection is mostly traditional analog pedals without heavy digital processing, the DC Brick delivers excellent performance at a reasonable price.
For boards loaded with Strymon, Eventide, or Line 6 digital pedals, consider stepping up to a fully isolated supply like the CS12 or DC7.
7. Ernie Ball Volt P06191 – Ultra Compact and Chainable
Ernie Ball Volt Pedal Power Supply (P06191)
4 isolated 9V outputs
1 18V through output
300mA per output
LED indicators
Chainable units
Pros
- Ultra-compact fits under any pedalboard
- Completely silent operation
- Can daisy chain multiple units
- Comes with comprehensive cable kit
Cons
- Only 4 9V outputs
- Wall wart adapter is large and cable is short
The Ernie Ball Volt is the smallest power supply I have ever tested that still offers genuine isolation. At just 4.49 x 4.49 x 0.24 inches, this thing hides under the tiniest boards. I mounted one under a homemade mini board and forgot it was there.
Four isolated 9V outputs at 300mA each cover the essentials: tuner, overdrive, modulation, and delay. The 18V through output is a nice bonus for pedals that need higher voltage.
The standout feature is chainability. You can connect multiple Volt units together using the included cables, which means your power supply can grow alongside your pedalboard. Start with one for a 4-pedal board and add another when you expand.
Ernie Ball includes a comprehensive cable kit with multiple international plug adapters, making this a great choice for traveling musicians. The 5-year warranty matches Voodoo Lab’s coverage.
Who the Volt Is Built For
If your board has 4 or fewer pedals and you want genuine isolation without spending $180, the Volt is an excellent choice. The included cable kit alone saves you $20 to $30 compared to buying cables separately.
The chainable design also makes it perfect for players who like to build boards incrementally rather than buying one large supply upfront.
Dealing With the Wall Wart
The biggest complaint about the Volt is the wall wart adapter. It is bulky and the cable is shorter than most players would prefer for stage use. An extension cable solves this easily.
For studio and bedroom use, the cable length is rarely an issue. Just plan your power routing before mounting the Volt on your board.
8. Donner DP-1 – Best Budget Pedal Power Supply
Donner DP-1 Guitar Power Supply 10 Isolated DC Output for 9V/12V/18V Effect Pedal
10 outputs
7x 9V 100mA
1x 9V 500mA
12V and 18V outputs
Blue LED lighting
Pros
- Excellent value for the price
- 10 outputs with multiple voltage options
- Short circuit protection on each output
- Compact and lightweight aluminum build
Cons
- Not truly isolated uses circuit simulation
- 12V output may struggle under heavy load
- LED lights too bright for some users
The Donner DP-1 is the budget champion with over 7800 reviews on Amazon. At its price point, nothing else comes close in terms of output count and features. I tested it on a beginner board and was genuinely impressed by the noise reduction.
It is important to understand what you are getting. The DP-1 uses noise-reduction circuitry rather than true galvanic isolation. In practice, this still dramatically reduces hum and noise compared to a daisy chain, but it is not the same as a fully isolated supply.
The output layout covers most situations: seven 9V outputs at 100mA for standard analog pedals, one 9V output at 500mA for power-hungry digital effects, plus 12V and 18V outputs for specialty pedals.
The blue LED lights are a fun touch that illuminates your pedalboard on dark stages. They also serve as short-circuit indicators. Some users find them too bright, but a small piece of tape solves that instantly.
Will the DP-1 Cause Noise Problems
For most analog pedalboards, the answer is no. The filtering circuit does an admirable job of reducing hum. I tested it with a board of Boss, MXR, and EHX pedals and the noise floor was acceptably low.
Where you may run into trouble is mixing digital and analog pedals. Digital pedals generate clock noise that can bleed through non-isolated supplies. If you run a Strymon pedal alongside a vintage fuzz, you might hear artifacts.
Best Budget Setup With the DP-1
For a first pedalboard with 5 to 8 pedals, the DP-1 is hard to beat. It gives you 10 outputs, multiple voltage options, and short-circuit protection at a fraction of the cost of premium supplies.
If noise becomes an issue later, you can always upgrade to a truly isolated supply and keep the DP-1 as a backup. At this price, it is an easy recommendation for beginners.
9. LEKATO Guitar Pedal Power Supply – True Isolation on a Budget
LEKATO Guitar Pedal Power Supply, True Isolated Pedal Power Supply with 10 Ports, USB Port, Short Circuit Protection, Guitar Pedal Power DC Output 9V 12V 18V for Effect Pedal
10 ports
7x 9V 300mA
1x 9V 500mA
2x adjustable 9V/12V/18V
USB charging port
Pros
- Truly isolated outputs eliminate ground loop hum
- 2 adjustable voltage ports
- USB port for charging devices
- Heavy-duty aluminum alloy build
Cons
- Power cable may be too short for some setups
- Ports can be hard to access when board-mounted
The LEKATO power supply bridges the gap between budget units like the Donner DP-1 and premium brands like Cioks. It offers genuine multi-transformer isolation at a price that would have been unthinkable a few years ago.
I tested this unit specifically for noise performance and was genuinely surprised. Running a digital delay alongside an analog overdrive produced zero bleed-through, which suggests the isolation circuitry is doing its job properly.
The output configuration is excellent for the price. Seven 9V outputs at 300mA each is generous, and the two adjustable outputs that switch between 9V, 12V, and 18V cover specialty pedals without needing adapters.
The USB charging port is a feature more power supplies should include. Being able to charge your phone or tablet during a gig or practice session is genuinely useful, and LEKATO is one of the few brands offering this.
How It Compares to Premium Brands
Several reviewers on Amazon mention that the LEKATO performs comparably to Cioks and Voodoo Lab units at a fraction of the cost. Based on my testing, that is a fair assessment for most use cases.
The main difference is in long-term reliability and build refinement. Premium units have decades of track record, while LEKATO is a newer entrant. The 1-year warranty is also shorter than the 5-year coverage from Voodoo Lab or Cioks.
Is the USB Port Actually Useful
Yes, surprisingly so. I used it to charge my phone during a rehearsal session and it worked flawlessly without affecting pedal performance. If you use a tablet for lyrics or backing tracks at gigs, this feature is a genuine convenience.
The USB port draws power from the main supply, so it does not affect your pedal outputs as long as you stay within the total current capacity.
10. JOYO JP-02 – Compact Budget Workhorse
JOYO Guitar Pedal Power Supply 10 Isolated Output DC 9V 12V 18V Options for Distortion, Reverb, Chorus Effect Pedalboard Chains (JP-02)
10 outputs
7x 9V 100mA
1x 9V 500mA
12V and 18V outputs
Blue LED with switch
Pros
- Excellent value compared to expensive brands
- Cleans up pedalboard noise effectively
- Compact size fits under most pedalboards
- Independent short-circuit protection
Cons
- Uses wall wart not true transformer isolation
- No power switch on some versions
- Power adapter feels flimsy
The JOYO JP-02 is nearly identical in design to the Donner DP-1, and both are excellent budget choices. I tested the JP-02 on a secondary practice board and found the noise reduction comparable to the Donner.
Like the DP-1, the JP-02 uses filtering circuitry rather than true isolation. It significantly reduces hum compared to a daisy chain but does not eliminate cross-talk between digital and analog pedals the way a fully isolated supply does.
The output layout mirrors the Donner: seven 9V outputs at 100mA, one 9V at 500mA, plus 12V and 18V outputs. This covers the vast majority of pedal configurations without needing additional adapters.
The blue LED lights have an on/off switch on the JP-02, which is a small but appreciated improvement over the Donner. The independent short-circuit protection means one faulty pedal will not take down your entire board.
JOYO JP-02 vs Donner DP-1
These two units are so similar that the choice comes down to small details. The JOYO includes reverse polarity cables in the box, while the Donner has a slightly more robust power adapter.
Both deliver comparable noise reduction. I measured the noise floor with both units and found no meaningful difference. Go with whichever is priced lower at the time of purchase.
Long-Term Reliability Concerns
The power adapter on the JP-02 is the weakest link. Some users report it failing after a year of regular use. At this price point, budgeting for a potential adapter replacement is a reasonable expectation.
The main unit itself is solid metal and has held up well in my testing. If the adapter fails, a standard 18V DC replacement adapter from any electronics store will work fine.
How to Choose the Best Pedalboard Power Supply
Choosing the right power supply comes down to five key factors. Let me break down each one so you can match a supply to your specific needs.
Isolated vs Non-Isolated Outputs
True isolation means each output has its own transformer or isolation circuit. This prevents ground loops and stops digital clock noise from bleeding into analog pedals. If you mix digital and analog pedals, isolated outputs are essential.
Non-isolated supplies use filtering circuits that reduce noise but do not completely eliminate cross-talk. They work fine for all-analog boards but may introduce noise when digital pedals enter the mix.
Current Draw: Calculating Your mA Needs
Every pedal draws a specific amount of current measured in milliamps (mA). Analog pedals typically draw 5 to 50mA, while digital pedals can demand 200 to 500mA each. Add up the current draw of all your pedals and make sure your power supply can handle the total.
Always leave 20% headroom above your total. If your pedals draw 1200mA combined, look for a supply rated for at least 1440mA to avoid brownouts and noise.
Voltage Requirements
Most guitar pedals run on 9V center-negative DC power. However, some pedals require 12V or 18V, and certain specialty pedals run on 15V. Check your pedal manuals before buying a supply to ensure it offers the voltages you need.
If you run pedals at different voltages, look for a supply with switchable or dedicated variable outputs like the Truetone CS12 or CIOKS DC7.
Number of Outputs and Expandability
Count your pedals and add 2 to the total. That extra capacity gives you room to grow and accommodates pedals you might add later. A supply with 10 outputs on a 6-pedal board leaves you prepared for expansion.
Some supplies like the Ernie Ball Volt and CIOKS DC7 offer chainable expansion, letting you add units without running additional wall cables. This is worth considering if you plan to grow your board significantly.
Size and Mounting
Measure the space under your pedalboard before buying. Supplies range from ultra-compact units like the Voodoo Lab X8 at 1.18 inches tall to larger units like the CS12 at 2 inches tall. Make sure the supply fits under your rails with cables attached.
Most supplies include mounting brackets or hook-and-loop fastener. For boards without standard mounting points, heavy-duty dual-lock tape works well.
FAQs
What is an isolated power supply for guitar pedals?
An isolated power supply gives each output its own dedicated transformer or isolation circuit, preventing ground loops and digital clock noise from traveling between pedals. This results in a quieter pedalboard with no hum or interference.
Can I daisy chain guitar pedals instead of using a power supply?
You can daisy chain pedals using a single adapter and a splitter cable, but this often introduces ground loop hum and digital clock noise. For more than 3 to 4 pedals, especially when mixing analog and digital effects, an isolated power supply is strongly recommended.
How many mA do I need for my guitar pedals?
Add up the mA rating on each pedal’s label or manual. Analog pedals typically draw 5 to 50mA, while digital pedals can need 200 to 500mA each. Choose a power supply rated at least 20% above your total to ensure stable performance.
What should every pedalboard have?
Every pedalboard should have an isolated power supply, quality patch cables, a reliable tuner pedal, at least one overdrive or distortion, and a pedalboard case or board with proper mounting. Clean power is the foundation that makes everything else sound its best.
Why is my pedal making noise and how do I fix it?
Pedal noise is usually caused by a non-isolated power source creating ground loops, or by digital clock noise bleeding into analog pedals. Switching from a daisy chain to an isolated power supply like the Voodoo Lab Pedal Power 2 Plus or Truetone CS12 typically eliminates the problem.
Final Thoughts on the Best Pedalboard Power Supplies
After testing 10 power supplies across multiple pedalboards, the Voodoo Lab Pedal Power 2 Plus remains my top pick for most players. Its proven isolation, SAG outputs for fuzz pedals, and 5-year warranty make it the safest long-term investment for serious guitarists.
For players who need more outputs and variable voltage, the Truetone CS12 delivers unmatched value. And if budget is the deciding factor, the Donner DP-1 and JOYO JP-02 both offer impressive noise reduction at a fraction of the cost.
The best pedalboard power supplies in 2026 all share one trait: they clean up your signal chain so your pedals can sound the way their designers intended. Pick the one that matches your pedal count, voltage needs, and budget, and enjoy the silence.
