Powerskin has introduced Pop’n ($80), an external 2000 mAh battery charger that affixes to the back of an iPhone 5, using a dangling Lightning plug for connectivity. Pop’n can adhere to iPhones and some existing iPhone cases by using small, flexible suction cups; the size of the Lightning connector will determine whether it works with a given case.
As one of the first Apple-approved external battery chargers for iPhone 5, Pop’n uses an LED light strip to indicate how much battery charge remains in the case. It extends power by up to 70 percent, and is available now in black and white, with red and pink versions to come.
