Harley Benton PowerPlant ISO-1AC Pro Modular

This provides enough power for modern, high end pedals. And they're all isolated. 500Ma is easily enough to daisy chain more units if required, and if you choose the right pedals to do this with, won't interfere with the sound quality (and of course you buy the extension unit for a few pounds if you want all isolated).

The unit is solid, well made and silent - no interference in my chain. You can plug it directly in to a UK socket with a standard UK IEC kettle lead. And of course you take it all over the world without difficulty. This is a third of the price of any serious competition. It also looks good. Top notch.

Two minor points: 1) normally Thomann throw in an English kettle lead for EU plugged items coming to England - this time they did not. But they are common leads and I had a spare. 2) If you use velcro/onboard fasteners then it's great but if you don't, no rubber feet are provided.

I was seduced by the small package and that it's packing a small punch for its compact size. (500mAh per output). I am powering a small pedalboard with a Boss looper, a midi controller, a tuner + a booster. Nothing too power hungry really. On paper it looked perfect. When I received it, it looked solid and not cheap, so it was another + and I was confident this was it.
But... the only time I used it live, power dropped on me. Briefly. Rendering my RC5 looper useless with an error message, until I unplugged it and plugged it back.
Maybe I got unlucky and the venue's power was inconsistent, making the juice drop for a second and hindered my live performance, but I couldn't take the risk to encounter this again while playing live. The HB powerPlant was the only new piece in my "pedalboard puzzle" and as I never had this before using PSUs, I had to send it back. I could recommend the solidity, the finish, the practicality of the product. All good. But unreliability was now shadowing all this. Unfortunate. I have to go back and keep looking for a more reliable unit.
