IMNEED 3200mAh Mini External Battery Portable Power Bank battery charger Charger for Smartphones Iphone 5S, 4S, 4, Samsung HTC MP3 Player (Pink) (Wireless Phone Accessory)
I have already tested a number of mobile chargers (with friends), but they were sometimes larger than the phone itself. Finally, here is one in lipstick format that fits in your pocket. The charge means this Power Bank, however, has not kept long, but back home you should do it already.
