I bought the Power Bank and it was just after 3 days break (1 they could not turn back; 2. the for charging the Power Bank provided connection has fallen apart). I thought to myself, can happen at any time, they have returned and ordered again. Since I have a new phone (S3 mini - previously galaxy Wonder), the Power Bank has also no longer reliably loaded. Eight months later, the connection is broken again .. this time definitively away with the thing. Too bad, but just not good.
