The PocketPower is a 6.4W folding solar charger with an "intelligent" voltage regulator that ensures devices will auto-restart the charging process in the event of an interruption in direct sunlight hitting the unit (due to cloudy conditions or the shading of the panels). The device weighs in at less than half a pound, and measures 3.98" x 5.59" x .59" when folded up, yet when open for use, it measures 15.63" x 5.59" x .05", so it's still small enough to clip to a backpack or other location, while delivering a 5V, 1.3A output for charging mobile devices or a battery pack. The laminated solar charger is said to be dustproof, completely waterproof, and "super durable," while the surface of the solar cells features a "deep embossing" that is said to improve the light absorption rate by adding a micro-texture that increases the solar conversion efficiency of the PocketPower.
