2000mAh Battery Backup External Power Pack for iPhone 4G
The 2000mAh battery backup external power pack is specially designed for charging Apple iPhone 4G that can power your iphone 4G at anytime and anywhere.
The sleek power pack snaps inconspicuously onto the back of your iPhone, adding only a few millimeters of thickness, but more than doubling the battery runtime. It prioritizes consumption, pulling power from the power pack first, maximizing the iPhone's internal battery.
Moreover, it is very simple to use. Just plug your iphone into the external battery, then you can operate your iphone as usual. But you can use it for a long time. Because it first consumes the battery backup power and then your iphone internal battery, so you can use for longer.
