I can't answer that question (although I suppose that the device switches to USB power – and that's also what I get from some usenet posts), but what's the current draw of a running 50g in the worst case? 100 mA? Less? So one hour of operation will consume not more than 5% of the mentioned 2200 mAh. Which leads to the question: how did you find out the power bank "was still full"? Does it have a battery system where you can at least approximately tell the charge level? Let alone discern subtle differences like 100%, 95% or 90%?
