If I had the money I would buy a second one to have as disposel. I think I might have destroyed the charging feature with a Huawei quick charger. Thought I might get 9 volts and 0,2 Amps more out of it - as in total of 9 volts and 2 amps as to say 18 watts. But... I does still somewhat charge, just not really as it should anymore.
I'm going to make a reset and see if it could just be a software issue, but sadly I think it is something in the Hardware. I do have 2 outside chargers so no problem as far as it goes. But I would not like to replace big batteries like the standard batteries to not wear out the plastic cover itself.
The original batteri died out, but I got 2 extra with the 2 chargers I ordered - Not sure how long they will last, but they are at a point where I'm thinking they might give in, in any moment. I have one Perfine 6400mAh and had ordered a 10.000mAh something of Perfine which was somewhat expensive from Amazon as it was impossible to find any other place at the time, but I never got it, and got something else and in end I never got the item and just lost money.
Anyway.... Perfine has been pretty nice, but it tends sometimes to disconnect if you bump it too much. But overall works pretty good beside that issue, and it might be because of wear of the cover. I wanted a 10kmAh so I did not need to think at all on the charging thing, you can quickly use up the batteries using the camera and it helps on the heat of the mobil itself!
