Many complain that Sony uses a proprietary power supply, instead of charging via USB to allow. Who knows Sony, knows this power cord or the plug: PSP and eBook Reader for example. There is a simple solution here. I use this cable, for example:;. = 1 psc Although unfortunately mini USB instead microUSB. But either one uses (like me) this an adapter mini / micro USB. Or you can just use only the Sony-specific plug. In any case I just tested it. The best of the PSP connector also works for this box: Charging via USB.
Otherwise: As confirm the other reviewers, we must at this size not expect any miracles, but in the context of what is possible, I am more than satisfied. In particular, the reduced price of 80 there is absolutely no reason to complain.
