Harley Benton PowerPlant ISO-1 Pro

OK, i got this to power a mix of pedals, kenton midi box and some cyclone TT models

so far it is faultless and running a moog minifooger drive, boss rv6 x 2, behringer OD 300, TT303, TT606, kenton midi thru 5, one more pedal to go to reach maximum (don't have it yet lol)

i should say this in case a reader is not aware, some of the above are digital, some are analogue - NO ISSUES, isolated outs - smooth

con #1 and only (haha if you can call it that)
i have had to supply my own polarity reverse cable for my kenton, still no issues

no noise, no issues, no nothing except nice blue lights (very bright) that sit under a laptop stand

wish i had done this years ago - for roughly 50quid this is a steal

built great, stylish, powerful - cannot recommend more I just wish THOMANN would always supply UK plugs especially when they know the country of residence, free adaptors are great but a UK psu would be better, hint cough

i should add that i only learned of these multi psu things this last year or so, what a great way to have one psu instead of 8!!!! Also, I only learned this harley benton gear is Thomanns yesterday - surprised and not surprised, thomann are a quality distributor/shop so why not have quality gear.

The Harley Benton PowerPlant ISO-1 Pro is a compact, fully isolated power supply designed to power a variety of guitar and bass pedals—both analog and digital. With eight isolated 9 V outputs (each up to 500 mA), it delivers clean and stable power while minimizing noise and ground loop issues.

Key Features:

8 fully isolated 9 V DC outputs (max 2000 mA combined)

Short-circuit and overload protection on each output

LED status indicator for each output

Compact metal housing suitable for pedalboard mounting

Includes 8 DC cables and one daisy chain cable

Powered by standard 18 V adapter (included)

In Use:

Users report clean, noise-free operation—even when powering digital pedals that typically introduce hiss or hum. The isolated outputs prevent interference between pedals, and the overall construction feels sturdy enough for regular use at home, in the studio, or on stage.

The bright LEDs are helpful for quick diagnostics but may be a bit too intense for some users, especially on darker stages. Included cables are decent, though all are the same length, which may require some creative cable management for cleaner pedalboard layouts.

Pros:

True isolated outputs for cleaner signal and better stability

Handles high-current pedals with ease

Compact and rugged design

Great value for the price

Easy to use with included cables and power supply

Cons:

DC cables are all the same length and mostly straight

LED indicators may be overly bright in some setups

Power input cable feels a bit thin compared to higher-end units

Not expandable—limited to 8 outputs as is

Final Verdict:
The Harley Benton PowerPlant ISO-1 Pro is an excellent choice for musicians looking for an affordable and reliable power supply. It offers true isolation, solid construction, and low noise performance at a fraction of the cost of similar units. While there are small compromises in cable quality and brightness, the overall functionality makes it one of the best options in its price range.
