I
not so great for what I need
IosifSimon 08.05.2026
I am powering up Mooer Yellow Comp (10mA), Nux Mg30 (≤ 400ma), Nux Queen of Tone (52mA), UAFX Ruby (400mA) and UAFX Enigmatic (400 mA) which totals 1262mA, which is less that what the ISO 1 pro can power, but the ruby and enigmatic are getting rebooted all the time because of current fluctuation I guess. There's something wrong with it and don't know if I can fix it.

Works, if you don’t use Fuzz.
Jinkxmonsoon 28.04.2026
Mine worked fine with all my pedals so far, but recently I got the Fuzz Factory and no matter what methods of separation, grounding and shielding I used, as soon at this power supply is connected, I get a twitchy high pitched noise, that fluctuates. (This is NOT from the fuzz factory, an it doesn’t make this sound when disconnected from the iso pro). So for almost everything it’s cool, but don’t expect it to work with fuzzes.

Avoid
DrKevGuitar 28.01.2021
(Edit) 18 months later: The power unit itself does the job well UNTIL I got a Strymon pedal. It injects noise into other pedals, which suggests this is NOT isolated as described. As they say "your mileage may vary". The extra stars are lost for my the following reasons...

The supplied dc cables are too thick and way too long, and a straight plug is needlessly annoying. No reason for it to be that way as Harley Benton sell much better double right angle cables at various shorter lengths themselves.

The power adapter functions fine, but it's larger and less conveniently shaped than a One Spot, and the cable is too short and too thin. Must be replaced with a 12V adaptor from elsewhere.

Finally, the blue LEDs are stupidly bright.

All in all, the lovely looking output box, does a great job with some pedals but not with others. Everything else requires replacement and therefore extra expense, hence two stars total.

It's not isolated!
vitaliistep 19.03.2018
Ok, I was very interested in this item, because the price is very attractive. I compared it to my MXR ISO-Brick and its build quality, materials, components, soldering, wires are even better than in MXR, but if we are talking about it as a power supply, it's just a noisy piece of power :)

I tested it with several analogue and digital pedals (Bogner, Empress, Tech21, Way Huge, TC...) and there are always some hum, buzzing and clicks. MXR ISO-Brick and separate Line6 power supplies are dead quite. So there is unfortunately no miracle.

Not as advertized.

It does not support modern digital pedals, at least not the ones I use.
