Inside a fake "10400mAh" eBay USB power bank.

The most annoying thing about this power bank is that the physical structure of it is great. It supports the four 18650 cells well and has a nice PCB mounting system. The battery wires have good clearance and it's altogether quite rugged. Shame about the capacity and the way the listing assured it was a "Guaranteed 10600mAh capacity". The whole unit is probably capable of being a much better power bank when built with decent components, but in this form it's clearly been made to look the part and cater to the fake specification market. On a plus note the cells do at least appear to be real 1000mAh ones and not a mixture of real cells and weighted cases.

By request, a generic eBay search link for the little plug-in USB flashlight :-
