Not bad, but ... 24

I have bought this emergency battery because the battery of my Sony NEX-5R was completely empty and I at the time had no additional external battery with this USB output.
So I wanted a battery, I can put in your wallet, and I really have always with you.
The built-in lamp is nice, and the first tests were good. The Samsung Galaxy Note 2 will be charged at 11%. So I was satisfied. Of course you can not expect miracles because of the small capacity - it is only for emergencies.
Now, however, the disadvantages:
- The micro USB connector is so clunky that I as the protective cover has to be removed until the Samsung Galaxy Note 2, before the plug fits
- The USB charging plug is sometimes very difficult in the USB port
- Although more than one device can be loaded so that Sony NEX-5R can thus not charged, what I bought the battery yes. The camera invites otherwise on any USB port or AC adapter. I do not understand. The camera simply will not charge the battery. There is another point deduction.
