It's alright

Its a great supply, very quiet etc but theres a major problem for me and that is anything that needs more than 500mA cannot be powered which makes it kinda useless for me to an extent, I can power my DS-1, Rocktuner Pt2 and my Germanium 4 Bigmuff but I can't power my Hardwire CM-2 and SC-2 because they draw 1.3A I also can't power my Small Clone because the supply isn't high enough ampage, came with the adapter for it though which I'm happy about, just can't power it haha. Gunna probably upgrade to a much more powerful supply like the MXR DC brick but till then this supply and batteries will work.

Morale of the story? Always see what current your highest current pedal needs so you have adequate power

Got lucky, apparently

Now I've seen other reviewers on the Internet saying this power bank was prone to dysfunctioning, sometimes even dangerously! I could not say this of mine however ; I've had it for 7 years and not a single damn problem! I don't know if it was from a better batch than those they make today, or just that they're all made with less quality control, but anyway, very satisfied indeed not to have had to shell out huge amounts for a power bank.

Heavy for 500mA

Really heavy unit, only 500mAm unfortunately i did not know that at the time of purchase or i wouldn't have bought this, but i use it to power a smaller pedal board, though it adds a lot of weight to it, but it does the job. really cheap as well
