The Mini Iso-Brick Power Supply supplies quiet, noise-free DC power to wide range of pedal types while taking up less space than a candy bar. 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.
First, let’s talk outputs. The Mini Iso-Brick Power Supply has five, 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. With a generous amount of current on tap and the ability to handle both negative and positive grounds, these outputs will accommodate almost any pedal, analog or digital.
And don’t let the five outputs restrict you—if you need to add an extra pedal, the Mini Iso-Brick Power Supply has you covered. It comes with a splitter cable that can be used to connect two pedals to a single output, provided they require the same voltage and you don’t exceed the output’s current rating. You can do this with all of the outputs simultaneously—just purchase the extra cables to do so.
Finally, troubleshooting can be a hassle on dark stages, so the Mini Iso-Brick Power Supply comes equipped with LEDs to let you know that all your connections are solid. Combine that with a lightweight housing that's built like a tank, and you can step on stage with confidence that your pedalboard will stay powered from gig to gig.

Cannot handle 300ma draw even though it says it can. I blew 2 outputs plugging in a 300ma pedal.Very disappointing considering it cost over $165.

I like the size of it but after hooking up my four pedals there’s as much noise as my old daisy chain. I literally hear no difference while switching back and forth. I have good cables and using the included adapter. All the pedals are boss or same 9 volt

Dunlop will only cover parts and service. I told them I need a replacement for a gig. They told me I need a backup one in case it dies. I have a backup unit that’s 12 years old and 2 more voodoo labs. I get it if it was a year into gigging, but it’s 3 months old. Zero gigs out of the house and only plugged in a power conditioner. Garbage…

Great product, all the noise from my pedal board is gone. I even have multiple pedals on a couple outputs and it works perfectly

I have the larger brick (more outputs), and have used it, without fail, for many years. This was a fantastic solution for a mini Pedal Train board. I only needed 4 or 5 outputs for a simple minimal board. It fits under the board. I expect this power supply to last a very long time. The additional goodies are a nice bonus.

I've been using this power supply for awhile. It works great and I like the easy to fit compact size. I highly recommend this power supply if has enough outputs to suit your needs.

It's good in that it provides true isolated power for you pedals. But as others have stated, the main power cable in goes loose easily. Also, for some reason it makes my volume/wah pedal buzz (which doesn't happen with my cheaper power supply unit). However, with my higher end pedals that require more current, it works totally fine. So it's good, but not perfect.

The MXR iso mini is great. It fits perfectly under my pedaltrain nano+. The seller, briskdrop, has excellent customer service. I ordered the bundle and my package was missing everything except the power supply. I emailed the seller and they returned my email within an hour. They went out of their way to make sure I was taken care of.
