Although the iPhone 3G can provide up to 5 hours of talk time on a single charge, that’s really not much of a feat. Most (okay, a few) geeks get outside with their iPhones anyways, so why not charge it during everyday use? The solar-powered iPhone case calms your battery woes with (you guessed it) – a solar panel! The case comes with a small 1500 mAh battery, which can be charged to a usable amount in 3 hours. A full charge will take 10 hours.
The case also comes with a mini USB adapter to charge via your laptop – in case you happen to be in a dimly-lit place. The case will be available in mid August, and will retail in both black and white versions for $54. Could be a worthy investment.
