Harley Benton PowerPlant ISO-2 Pro

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

I bought the Harley Benton PowerPlant ISO-2 Pro almost 3 years ago. Since then, it's in operation a couple of hours each day (give or take) in a bedroom setting, powering various effects pedals through all 8 outputs.

The Harley Benton PowerPlant ISO-2 Pro includes everything necessary to get started with using a power supply - no additional purchases are necessary. The power supply unit comes in a sturdy brushed aluminium housing that feels robust in hand. It's lightweight, small, and fits snugly underneath the Harley Benton SpaceShip 60 pedalboard. The included plugs (cables) are typical cables and don't seem of bad quality. The power adaptor looks and feels like cheap plastic, but it has proven to be reliable so far.

The unit produces no noise and introduces no noticeable noise to the signal chain. There is no dedicated power button so it's good to have a switchable power strip on hand if it's necessary to switch the unit on and off on demand.

Overall, the Harley Benton PowerPlant ISO-2 Pro provides great value at a reasonable price point. It's a particularly great purchase for those noodling around at home or at practice, looking for a first proper power supply to replace "daisy chains."

If you only use analog pedals (these tend to draw VERY little current) you absolutely do not need more than this. Being fully isolated under €100 bucks is great. To be that under €70 WITH extra selectable voltage on two outputs? I mean, you could spend more money, but why?

As for digital pedals... it depends. Digital pedals ALOT more power than analog ones and at 300mA max current per ouput, loads of pedals will be out of range. Keep in mind you should always leave some current to account for spikes, so if your pedal needs 280mA and you have 300mA available, it will work, but you might be unlucky if your mains craps out on you. The good news is that since the power supply has all isolated outputs, you'll only blow the one pedal.

Silver linings I guess...

The power supply is fantastic, with some extra daisy chaining I have managed to run 15 pedals off of this supply for numerous gigs with zero issues - one time my bandmate forgot his 9v wall wart and I was able to power his full board, as well as mine from this unit.

It doesn't overheat and doesn't add noise - Very cool!

The wall transformer (plug) however is super fragile, a light accidental kick pulled the wire straight out of mine not longer after ourchasing the unit. Replacements are available straight from Thomann and are less then €10 - so not the end of the world. Just take extra care and you will have zero issues.

Great supply all in all!
