Powerspring iPhone battery case

powerspring battery case_60MiLi has announced what it claims is “the thinnest iPhone battery in the world”.

Powerspring is a dual-purpose mobile battery case for the iPhone (currently 3G and 3GS only). Not only is it a protective case for the iPhone, it's also a battery charger that MiLi claims doubles the life of the iPhone battery, without needing to plug the iPhone into a wall socket charger.

It is a one-piece case with a thin rubber hinge connecting the main bottom part, and the top part that flicks back to allow the user to slide the iPhone into the case and then flips back to its original position to secure the iPhone in an all-round case.

The £44.95 Powerspring is compatible with the iPhone 3G and 3GS, with an iPhone 4 version planned.
