There’s many battery cases on the market, but we recently ran across a unique charging case from Prong called the PocketPlug. The phone case features flat-folding plugs that can be deployed with a the flick of a finger, allowing you to easily charge your phone while on the move. It also gives you the option via a micro USB port.
The Prong PocketPlug is available for the iPhone 4, iPhone 5, and Samsung Galaxy S III at the brand’s website for $70.
