Want an inexpensive external battery for your iPhone 4 or 5? There's a great deal you should know about that's running this weekend only.
Battery case maker PowerSkin is offering a special one cent deal this weekend on their PoP'n, an external battery case that works with some iPhones and Android phones. The deal is open to anyone in the U.S. and saves you about $48. You'll still pay $10 for flat-rate shipping, but even then it's a pretty solid bargain, especially if you're looking to get more life out of your smartphone.
