This is the iPhone4 case that recharges from the sun to extend phone operation. Providing up to five additional hours of talk time, eight hours of Internet use, or video playback and up to 32 additional hours of MP3 playback, the case's built-in battery can be charged in the sun by turning the case onto its back to expose its solar panel. It can charge by itself or when slipped onto an iPhone4 as a case, connecting to a phone's 30-pin connector. The battery fully charges when in direct sunlight. Leaving the case's power switch off retains its charge until switched on; four blinking LEDs indicate the battery is transferring its charge to power an iPhone4. The case can also charge via a micro-USB cable (not included) when sunlight isn't plentiful. 5" L x 2 1/2" W x 3/4" D. (6 oz.)
