The unit was delivered quickly and pointed at his arrival neither damage nor other defects. Connected - tried - works. Displays Conveniently, the charge state of the battery. I've tried all kinds of batteries, even the USB socket. Everything works fine. Unfortunately always need two batteries of the same kind either in the two right jacks or the two left sockets, so that the charging process begins. That will probably have any technical reasons. I've already experienced with other chargers, so there is no deduction for. The product I can recommend in good conscience.
