QYG-power FC5 is an incase Power Slider: By far, the Power Slider had the best design. The three-part design completelyencases the iPhone, increasing the dimension only slightly. It's a little wider, a little longer, a little thicker, and a little heavier. But it's a very natural look, and most people wouldn't even realize it's also a battery pack. It's pretty easy to put on and take off, and feels like a second skin in the end without impeding the camera. Real 1900mAh built-in battery,  double the time you have to Rock, Talk, Surf and Send with your iPhone 3G or 3GS. Also with built-in USB cable for data transmission at your very convenience.
