One of the big problems that many iPhone users complain about is that the battery life on the various iPhone models just isn’t that great. One of the ways that I get more use out of my iPhone is with a Mophie JuicePack, but that still needs to be plugged into an AC outlet to charge.

A company called MotionTouch has announced a new iPhone charger that gets power from the sun or some ambient lighting to charge the battery inside the sleeve. The device is called the Powcell sleeve and it slides onto the back of the iPhone much like the Mophie offering.

The rear of the sleeve is covered in a solar panel that charges the sleeves internal battery even when it isn’t connected to the iPhone. The maker says that the sleeve doesn’t block any of the features of the phone. Pricing and availability for the charger is unknown.
