Buyers Tips: Why you need a power supply, and what to look for

If you invest in a dedicated power supply that provides isolated power for each of your pedals, and can handle multiple voltages as well as providing both AC and DC supply, then you’re going to eliminate a ton of problems in one go.

  • You won’t need to keep track of what voltage each pedal uses.
  • You don’t have to worry about having enough power outlets within reaching distance of your cables
  • Never worry about batteries running out halfway through your set
  • Remove unwanted hum caused by daisy chaining
  • If you have Strymon pedals that have huge milliamps (mA) requirements, most of these can be powered much more simply by a good power supply unit.

You’ll need to be aware of both the current and voltage requirements of your pedals, as well as if they’re AC or DC powered. Getting these wrong can lead to... shocking results. (Sorry! I couldn’t resist, the urge was too powerful)

Now that we’ve considered a few aspects of how pedalboard power supply units operate, let’s take a look at some actual units and what separates the best from the rest.

​5 Best Pedalboard Power Supply Units

To make things easier for you, we've added pros and cons for each one, as well as a video demonstration so you can see them in action. So without further ado, let’s take a look...​

1. Voodoo Lab Pedal Power 2 Plus (Editor's Choice)

Voodoo Lab Pedal Power 2 Plus Isolated Power Supply

An extremely versatile power supply that lets you change the voltage requirements so that you can handle nearly any pedal requirements. In addition, purchasing a single Y-cable addon allows you to combine two of the 9V outputs into a single 18V output, or two 12V into a 24V output. It also offers up to 240mA current. Compared to others, this is one of, if not THE best pedalboard power supplies. It’s only real flaw is the cost.

  • 8 isolated outputs, so no unwanted interference
  • Inputs can be switched to provide different voltages (up to 12V and down to 4V)
  • Includes an AC input
  • You’ll need to spend extra to create an 18V outlet
  • A high end purchase, make sure you need it before you buy it
  • Limited to 8 outputs, or less if you need an 18V supply

2. T-Rex Fuel Tank Junior

T-Rex Fuel Tank Junior power supply

A lightweight power supply with a small body that can power up to 5 pedals as long as they don’t need more than 120mA. Like the Voodoo Labs unit, you can use a Y-cable to combine the 9V outlets into an 18V outlet, but 12V and 24V aren’t an option.

  • Cheaper than the Voodoo Labs
  • Small size makes it a good addition for a pedalboard with space at a premium
  • Can be daisy chained from to add more than 5 pedals (but this will bring in a hum)
  • No 12V or 24V pedals
  • Only supports pedals that draw 120mA or less
  • Five outputs makes sacrificing two to create an 18V outlet more painful than on the Voodoo Labs

3. Walrus Audio Phoenix

Phoenix 120V Clean Power Supply

If you’ve got a monster set up that needs more than the 8 outlets provided by the Voodoo labs unit, the Walrus Audio Phoenix provides isolated power for up to 15 pedals at once.

  • Very versatile, with inputs being switchable to handle a huge variety of power needs up to 300mA, 9V, 12V and 18V and an AC outlet
  • Interesting artwork that makes it probably the only good looking power supply (image is everything in show business!)
  • No need to daisy chain pedals and deal with the annoying hum, as you will probably struggle to use more than 15 pedals in one gig
  • Absolutely massive unit, so a pedalboard with room underneath for stashing it will be a good combination
  • All the outlets are cramped together in one tiny space, making it awkward to use all 15 at once
  • Comes in at a hefty price

4. Truetone 1 SPOT Pro CS12

Truetone 1 SPOT PRO CS12 with 12 Isolated Outputs

A true competitor to the Voodoo Labs, perhaps even beating it out thanks to the extra number of pedals it can supply.

  • The 18V outputs can be broken into two 9V outputs with a converter cable, meaning it can compete with even the Walrus Audio Phoenix in terms of capacity
  • Each of the outputs are given plenty of space around them
  • Includes colour coded cables for easier organisation
  • Designed to be used with a Pedaltrain pedalboard, so if you have a different one then you can’t take advantage of the mounting brackets
  • Like many isolated power supply units, it’s not cheap
  • It’s not small by any means, so be prepared to sacrifice some serious space for this unit

5. Dr Tone PSU10 (Budget Choice)


If you don’t have tons of different pedals, and only need to be able to supply 9V for the vast majority of your pedals, alongside one or two 12V pedals, then this is a much more budget friendly option for guitarists that don’t need the versatility of the others mentioned.

  • Supply up to 10 pedals at once2 outputs can switch between 6, 9 and 12V supply
  • One of the smallest isolated power supply units making it ideal for cramped pedalboards
  • One of the cheapest options available
  • Lacks the flexibility of the Voodoo Labs and Truetone units
  • Outputs are arranged on two sides of the unit, which can make it easier or harder to connect to your pedals depending on the layout of your pedalboard

So which should I buy?

You have a choice to make when deciding which is the best pedalboard power supply unit to purchase. If you have the money to burn, it’s going to be either the Voodoo Labs Pedal Power +2 or the Truetone 1 SPOT Pro CS12, hands down.

The only possible exception to this is going to be if you only need to power a handful of Boss pedals or others than only need a 9V DC power supply, and you don’t want to waste a ton of money on versatility that you don’t need. In that case, you can’t go wrong with the Dr Tone PSU10.

As always, comments are appreciated as they can help make the difference to another guitarist that’s struggling to make a final decision, so let us know what your experiences with these power supply units have been!​
