Does what it says

I bought this for my Boss AD 10 and RC 500 also have a Roland SPD one plugged in.
The 2 Boss pedals required more power than my power supply would give. This works perfectly.
This is an excellent option. I have had no noise from the unit. Fully powered it lasts days. Takes a full 24 hrs to charge up using a regular Samsung phone charger.

Its cover is made of plastic probably not going to take too much abuse. It's a fairly large size. Doesn't fit neatly under my pedal board.

It's a brilliantly designed device. it can work both powered from the socket and on a battery that lasts longer than you are able to play, practice or play a concert. Harley Benton has proven that its power supplies are exceptionally good at such a low price. And in the case of this version, the voltage does not go below the minimum.


They send me a faulty unit, beware if you are in need!

It seems the Mk2 version has not passed properly the quality tests, they send me a unit that does not power on and I was in desperate need of a new power supply.

The design looks very nice, it looks very convenient, but unfortunately the quality checks were probably non existent for Harley Benton in this new version

Die beste Powerbank die ich je hatte :-)

Hatte schon die Version MK1 seit längerem ohne Probleme in Betrieb. Diese Version setzt die Messlatte nochmal höher und das erfreuliche ist, dass ich keinerlei Störgeräusche oder Brummen feststellen konnte.
