iPhone 3G users have been complaining about the iPhone's battery life ever since it launched in the market. It manages to run for just one whole day, that too with 3G turned off, says Mobile Fun.

To combat this problem, Mobile Fun has come up with a solar-powered case for the iPhone 3G. In addition to protecting the device from scratches and damages, this case also charges it. The case comes with a large high capacity 1500mAh battery, allowing users to charge from a solar source and store the power for one full charge of the iPhone.
The case recharges itself through the solar panel mounted in front of the case, or via mini USB if in a badly lit area. The mini USB can also be used to charge other devices from the case.

Charging time for case: 3 hours approx

Stylish and practical carry case for your iPhone 3G

Flip style carry case for quick and easy access
