Best Pedal Power Supply

I will try to single out the best pedal power supply at the end of the article with a pedalboard power supply comparison followed by the buying guide.

1) Donner DP-1 Cheapest Isolated Power Supply for Pedals

Donner DP-1 Cheapest Isolated Power Supply for Pedals
TypeIsolated Power Supply
Output Voltage9V, 12V, 18V
Number of Outputs8
Switchable VoltageN/A
Dimensions6.5 x 6.2 x 2.4 inches

When I first came across DP-1 Cheapest Isolated Power Supply for Pedals, I was soon fascinated by its aesthetics. It has 8 individually isolated outputs that exceed the output numbers of similarly priced units. It has advanced protection features such as short circuit protection and all LED indicators for each output that separates it from other competitors.

Build and Aesthetics

The LED lights on the Donner power supply ensure that you always have information about the channel’s status, whether they are on or off. The lightweight construction and portable design ensure that you can take it anywhere you want for live performance.

Independent Power Interfaces

Another selling factor was that the individual power supplies in Donner DP-1 were wholly separate and used a unique power interface (18b). With this particular voltage regulator circuit, which I believe provides us musicians with a sense of security, we can be confident that the Donner DP-1 will keep running whenever we need it.

No Isolation

There are seven 9V 100mA outputs, plus one each 9V 500mA, 12V 100mA, and 18V 100mA, for 10 outputs and 13.8W. All the 9V outputs connect to the same voltage regulator, so they’re not isolated from each other. The higher current 9V output just has a larger filter capacitor.

Practical Indicator Lights

Donner DP-1 comes equipped with blue LEDs that ensure that you are aware of the connectivity. A switch lets you turn on and off the lights to operate the pedal power supply at your ease.

Affordable and Budget Friendly

The DP-1 is the best budget pedal power supply that provides eight isolated outputs and is suitable for powering up to eight high current devices. It’s also one of the few units able to power up to 18V-rated devices and comes with a 5-year warranty.

  • A durable and compact metal case offers good protection.
  • Inexpensive power supply with various pedal connectivity.
  • It has ample outputs to cater to your needs.
  • The lightweight build makes it suitable for carrying around.
  • Outputs are not entirely isolated for the 9-volt ports.
  • Internal circuits are not comparable to the fully isolated power supplies.

Voodoo Lab makes such fantastic devices that they can help you get the best of your pedal power. The Pedal Power 2 PLUS is their most popular model because of its versatility and quality features.

I recommended it to the fellow guitarists who complained about the noise and hum they received when using other power supplies. They claimed to get a noise-free experience for the guitar performance.

Isolated Regulated Outputs

I find the location of DIP switches attractive as a block of these switches sits at the bottom of the unit. These switches let you control the isolated outputs. When the button is in the normal position, it does regulate 9V. The presence of 250mA output as 5 and 6 number output is perfect for high current pedals while rest outputs are 100mA.

Highly Practical Pedal

The Voodoo Lab Pedal Power 2 Plus is a highly efficient power supply that includes isolated outputs. Its practical size and design appealed to me, and the fact that it contains eight 9V outputs helped me make my decision. It can power any compatible pedal, and each of its outlets is isolated, ensuring the highest quality sound for your pedal effects.

Short Circuit Prevention

Voodoo Lab has incorporated a series of clever protections into the design, and I was glad to learn that all outputs have protection from the potential issue of short-circuiting.

In addition, each output is regulated and highly filtered so that electronic hum doesn’t make its way into your equipment. It helps ensure your pedal will deliver the cleanest sound possible when plugged in at home or on stage.

Huge Versatility

The Voodoo Lab Pedal Power 2 Plus provides adequate power for nearly any pedal setup. It even has more than enough room to support up to 10 pedals. This unit should be sufficient unless you have an extensive collection of effects pedals to connect.

  • Every output carries a dual-mode operation.
  • There is no ultra-low noise.
  • The voltage is variable for diverse compatibility.
  • It has clean power.
  • Cable length seems short for live performances.

Best Pedal Power Supply Purchase Guide

If you want to get the correct power supply for your guitar, the pedal power supply guide will let you make an informed decision. Keep the following features in mind when buying the best pedal power supply according to your needs.

Voltage Requirement

One must consider the power source required by their equipment. Most pedals, for example, will need at least 9V to run, while others might be able to function with either 9V or 18V, depending on the model in question.

Similarly, some pedals allow you to vary the voltage within specific ranges meaning that you’ll effectively have enough room to customize your experience and tailor it to your liking. Make sure your power supply has all the proper voltages available so you don’t damage the pedal and cause dangerous mistakes on stage.

Isolated Power Supplies

When searching for the best pedal power supply, it is vital that you first determine whether or not you need isolated power. Outputs that are not isolated share a standard ground connection, and as a result, your board can pick up on electrical interference. The board will pick up hum interference from each source with multiple paths to the ground.

An isolated power supply has individual outputs separated from the others by a transformer, voltage regulator, optoisolator, or integrated circuit with an internal LED. They cost more because they contain additional components, but they solve all the mentioned problems. If you want your device to work reliably, choose one of these.

Size & Shape

Power supplies come in different shapes and sizes, and it’s important to know that one might not fit your needs exactly. Using a smaller power supply may mean you will lose valuable space on your pedalboard because it won’t be under-mounted. However, some power supplies happen to have the ability to fit underneath.

Number of Outputs

If you want to power your pedals for years to come, you must buy a power supply with enough juice. Smaller power supplies are used to power 2-4 pedals, but larger ones can handle up to 12 pedals. Make sure you get one with enough space for your future upgrades.



Whether you like to perform guitar solo at home or a party, the best pedal power supply is to provide the best experience. While testing and evaluating the performance of the power supplies, I have found some significant improvements.
My personal favorite for flawless performance is Donner DP-1 Cheapest Isolated Power Supply for Pedals which is best for its aluminum finish and high build quality. It has 9V, 12V, and 18V outputs to help you connect each pedal with different voltage demands. Overall, it is a solid performer with fully isolated outputs that makes the power supply stand out in the competition.
