10 best pedalboard power supplies to buy in 2019

To save you the hassle of trawling the internet for the best available, we’ve picked out the 10 power supplies we believe are the best on the market today.

It might not be the most glamorous piece of equipment in your arsenal, but your power supply of choice is vital to the performance of your pedals and their marriage on your ‘board. To save you the hassle of trawling the internet for the best available, we’ve picked out the 10 power supplies we believe are the best on the market today.

Truetone 1 Spot CS12


A 12-output powerhouse, Truetone’s CS12 boasts, as you’d expect, 12 fully-isolated outputs with high-draw ones included. It also offers two AC outputs, perfect for making sure you never part with your old DigiTech Whammy to piss off your neighbours with your pastiche of Tom Morello for the umpteenth time. Surprisingly affordable given the level performance it produces, its hard to find any negatives around the CS12.

Price: $269/£195
Type: Isolated power supply
Isolated outputs: 12
Switchable voltage: Yes

Voodoo Lab Pedal Power 2 Plus

Voodoo Lab, along with the aformentioned Truetone, is the company you’re most likely to see on the pedalboards of the pros. Their Pedal Power 2 Plus is rugged, reliable, includes nine isolated outputs and has the versatility to please even the most pedantic of players.

Price: $169/£159
Type: Isolated Power Supply
Outputs: 9
Switchable voltage: N/A

Cioks DC7

Whilst we could have opted for Cioks DC10 or even ADAM, we chose the DC7 simply for impressively compact format, especially given the amount of outputs on board, and its ease of use. It offers recessed dual DIP switches for each output to set the voltage to nine, 12, 15 or even 18V, and the available current per output is 660mA, dropping to 330mA if you set the voltage to 18V. The DC7 has a built-in IEC mains inlet, which can automatically entertain mains voltages from 90-265 Volts AC, at 50 or 60 Hz. It’s not cheap, but for this form factor, seven outputs and a built-in IEC, it might be just what you’re looking for.

Price: $229/£225
Type: Isolated power supply
Isolated outputs: 7
Switchable voltage: Automatic

MXR Iso-Brick

An updated version of MXR’s increasingly popular DC Brick, the Iso-Brick is basically that exact same enclosure, warts and all, but with full isolation. With a variety of different currents on offer via its ten outputs, and also including two 6-15V variable voltage outputs that can emulate voltage “sag,” this silver box is the perfect upgrade to its DC only sibling. It also comes in a five output format too, if you’re looking for something slightly more slimline.

Price: $214/£199
Type: Isolated Power Supply
Isolated outputs: 10
Switchable voltage: N/A

T-Rex Fuel Tank Jr

Perfect for small and medium sized ‘boards alike, the T-Rex Fuel Tank Jr is both a streamlined and wallet friendly solution to your demand for power. The most compact of T-Rex’s four Fuel Tank units on offer, the Jr boasts five isolated 9V DC outputs and also includes all necessary cabling. Each output delivers 180mA and you can also use two outputs simultaneously to power 18V pedals. It doesn’t offer a lot of outputs, but what it does offer is robust and affordable.

Price: $145/£110
Type: Isolated Power Supply
Isolated outputs: 12
Switchable voltage: Yes

Pedaltrain Volto

Now in its third iteration, the Volto is still one of the best emergency power supplies to keep tucked in your gig bag. A revolutionary product when it first appeared, it was widely regarded as the first rechargeable and truly portable option for pedal power. Pushing out 6200mA of power and charged via a USB, this green machine is great for mini pedalboards and for those of you that simply need power for one pedal, but don’t want to have to lug around a power supply and extension lead when you’re gigging. Featuring two outlets and multiple PSUs in the box, the under £100 price tag is almost too good.

Price: $99/£80
Type: Rechargeable power supply
Isolated outputs: 12
Switchable voltage: N/A

Walrus Audio Phoenix

The Walrus Audio Phoenix is an absolute behemoth of a power supply. Offering isolated power for a total of 15 different pedals that can handle power from nine to 18V, it also has four 300mA outlets to hand for those power hungry pedals whilst keeping your noise floor low and your signal squeaky clean. This is achieved by torroidal transformers, apparently, and the unit is also shipped with 15 – 2.1mm barrel black power cables, 2 – 2.1mm barrel red (center positive) cables and a detachable IEC cable. We’re big fans of Walrus Audio’s work at Guitar.com, and this supplier of sheer power is only adding to that.

Price: $279/£182
Type: Isolated Power Supply
Isolated outputs: 15 (plus 4 high-current 300mA outputs, 2 switchable 9-volt/12-volt outputs, 1 switchable 9-volt/18-volt output)
Switchable voltage: Yes

Truetone 1 Spot

The ultimate beginners choice, this compact power supply from Truetone can drive even the most demanding of digital pedals. The 1 Spot’s main selling point is that it’s easily configurable to allow for multiple PSUs on one plug, letting you daisy chain to your heart’s content. Whilst you might balk at the price for what is essentially a simple PSU adapter, note that the ability to power multiple stompboxes all on one strip puts it ahead of your standard adapter. If you’re in desperate need of pedal power and don’t have much dough to spare, you’d be hard-pressed to find a better deal than this.

Price: $24.95/£19.99
Type: Wall socket power supply
Isolated outputs: 1
Switchable voltage: N/A

Pedaltrain Spark

Arguably the best option for those that prefer to use Pedaltrain ‘boards, the Spark has been specifically engineered to fit underneath the company’s Nano and Metro offerings, without the need for any drilling or overzealous modding. Squeezing five isolated outputs into this form factor is a feat in itself, whilst it also includes short circuit protection and output regulation. Despite leaning on the expensive side, it does come with a Pedaltrain mounting kit, and does allow for your mini ‘board to stay lean and clean, letting you ensure none of your precious real estate is taken up by an unsightly chunk of metal.

Price: $199/£188
Type: Isolated power supply
Isolated outputs: 5
Switchable voltage: N/A

Mooer Micro Power S8

Coming in at a more budget-friendly price point, the Mooer Micro Power S8 combines isolated and non-isolated outputs in a sturdy and robust package. Four fully isolated outputs alongside four non-isolated outputs, which all share 400mA combined. Whilst that’s not a particularly large amount, it’s more than enough to cover the majority of digital pedals. If that doesn’t cover your needs however, there’s a handy LED above the output to indicate whether the pedal requires more power than what’s available. It also includes surge protection and a voltage switch to make it usable worldwide. Not bad at all for a box that comes in just shy of 100 bucks.

Price: $98/£79
Type: Partially isolated power supply
Isolated outputs: 4 (plus 4 standard outputs)
Switchable voltage: Yes
