Whether you need a space-saving solution for your downsized travel board or you just need to power a small, carefully curated selection of tried-and-true staples, this little box has what you need—all while taking up less space than a candy bar.

The Mini Iso-Brick Power Supply has five outputs, and each is fully isolated to eliminate obnoxious, gig-ending ground loop noise. Four of the outputs supply 9 volts of power at 300mA, while a fifth can be set to provide either 9 volts or 18 volts at 800mA depending on your needs.


  • Includes - 5x DC cables and 1x Y-splitter cable to allow two 9V pedals to be connected to the 18V output. Also includes 18V 2000mA mains power adapter
  • Features - 5 isolated outputs (max output 2000mA): 4x 9V/300mA & 1x switchable 9V/18V 800mA

As above, fast, accurate and knowledgable

If you're running more than 2 pedals, particularly 18v, this is the very dab. All mysterious noises cease. Your guitar sound improves massively because your overpriced pedals are actually getting enough current to work properly. Bit of an epiphany. And it's so tiny.

Joseph N. - 15/4/2022

Very convenient and so easy to set up.

Perfect for my home pedal board setup. Clean power and clean sound. Still can?t believe how small it is.

Christopher S. - 6/10/2020

Powers my pedals perfectly and noise free.nice and compact.

Stephen S. - 31/8/2020

Really tiny power supply that would fit any pedal board. Easy to use and hum free.

Mark S. - 26/7/2020

Needed to upgrade the power supply for my pedalboard. Saw some reviews for this product and decided to give it a try and was not disappointed. The unit is very small but is excellent quality and slotted onto my board perfectly and now there is no noise from my board at all. Great unit.

Keith H. - 25/7/2020

Compact and robust.

HUGH L. - 13/2/2020

Not much to say about this other than it works fine and keeps signal noise down. Very dinky size, so ideal for a small pedal board. 18v option on one input is useful.
