The Battery Life Extending iPhone Case

This is the protective case with a built-in battery pack that effectively doubles an iPhone's talk time. The battery provides up to four additional hours of talk time on 3G phones (eight hours for 2G), up to 4 1/2 hours of additional WiFi time on 3G phones (five hours for 2G), and up to 240 additional hours of stand-by time. It provides up to 17 hours of audio play and five hours of video play. The case's battery recharges from AC, a car's 12-volt DC port, or a computer's USB port using its three-way adapter. An additional USB port in the adapter enables charging of a second device. The slim rubberized ABS case protects an iPhone at all corners, providing access to all iPhone switches and ports. Includes integrated LED that illuminates subjects for photographs or videos. Works with iPhone 3G and 3Gs models. 5" L x 2 1/2" W x 1/2" D. (9 3/4 oz.)
