Probably all the power you'll ever need
albertotp, 20.05.2019
It's incredible what they achieved with this design, including many features of more expensive products in a relatively compact format and for a decent price. Quality-wise I cannot complain about it and I had no issues and no noise powering 6-7 pedals including digital tuner, modulation, looper, and using 12V and 18V options.
Many other reviews already mentioned that the power adapter could be more robust. Other thing is that all DC cables have 1 straight and 1 angled connection, which may not fit everyone's need. All DC cables have the same length and are too long, which is better than being too short, but for small boards plenty of cable management is required. I had to buy 2 additional short DC cables for it.

I've made a full review and isolation test here: youtu.be/NZqCcpu81rY

I've also managed to fit it under the Spaceship 50c by making slight modifications to the board: youtu.be/h8Lkg5a4ahg

OK but somewhat noisy
georgebranekov, 12.10.2020
Bought this unit to accomodate more pedals, including some digital quite hungry ones. While it powers everything just fine and there is no lack of power, it is somewhat noisy and "sounds" dirty. Definitely some noise goes through and as a result you get a suckier tone. Tried removing pedals from the chain and changing cables and wall sockets, problem leads always back to the power unit. I am dissapointed, although if you play in a place where electric installation is perfect maybe won't be so much of a problem. I switched back to the Harley Benton Junior brick, which works perfectly well and there is no noise whatsoever, and for the hungriest digital pedal just opted for a Boss wall adapter. Done, no noise. I wrote in my HB Junior review that if I needed more power, I would get a second one - I wish I did instead of buying the ISO-2 Pro.

A Clear Choice
Sebastian_T, 09.07.2018
I bought this power supply on a whim, because I had a Powerplant JR and around 9 pedals that needed powering. Coming from the JR, I had to use ABY cables to create sort of a daisy chain to power multiple pedals from a single output, so that's why I bought this - more outputs, isolated, promising looks and features.
I do not regret that decision. This supply is the real deal - it's truly isolated, it has no hum, no noise, providing stable power to my pedals (even better than the JR, which sometimes had fluctuations).
It is way smaller in reality than it is in the pictures - I was expecting a bigger power supply altogether, since the JR is quite tall and wide, but this one is thin and small. Albeit small, it feels solid, made of metal.
The only complaint I have about it is that I have had a hard time fitting it in my Harley Benton pedalboard, because on the JR, I used the angled ends of the cables in the pedals and the straight ones in the supply. Now I have to go angled in supply because otherwise they wouldn't fit in the pedalboard, so keep this in mind if you have a tight space there, you'll probably have difficulties fitting the cables.
Oh, also, the JR came with way more cables than the ISO-2 did, which was a bit disappointing.
Other than that - this supply is golden. Comparing it to my T-Rex Fuel Tank Classic, I see no reason to go the extra miles and throw the difference to go for the T-Rex, now after using both the Jr and the ISO-2 Pro.

Excellent power plant for pedals
H. Gabor, 19.07.2020
I bought this unit for my pedal board.

It's a very well designed power plant for an ubelievably reasonable price. It's small, practical, durable, good-looking, reliable. Adapter and a set of plugs are included that is a big pro. With eight outputs plus daisy chain possibilities, it can supply a whole pedalboard. In my experience It works without adding up extra noise.

The two adjustable outputs can be very useful. For example I have an old Boss pedal, still usable, that requires 12V when it runs on an adapter and not on battery. With this powerplant I could easily organise that old pedal into my signal chain containing more modern units with 9V power supply.

Cons: The adapter looks a bit vulnerable, particularly its cable. I guess it should be a bit more heavy duty unit for travelling or working on stage.

I definitely recommend it.
