Slim Solar-Powered Smartphone Sleeves

Although there have been a few cell phone sleeves that charge up one's batteries using the sun out on the market for awhile, the EnerPlex iPhone case is one of the thinnest of the bunch.

Created by Ascent Solar, the sleeve is ultra-thin and only adds about 2 ounces to the original weight of the phone -- which is next to nothing compared to its bulky, heavy-weight competitors.

The case provides against minimal bumps and jolts to the phone while also using its embedded solar panels to charge up a dying battery by harnessing energy from the sun. The Eco-Friendly charger also leaves the phone's rear camera clear for taking photos and provides unrestricted access to the the phone's other features.
