PowerSkin has just released the PowerSkin PoP’n phone charger. What makes this external battery unique is that it clips around almost ANY existing case you may already have on your phone. Use the extra power when you need it, when you don’t unclip it and throw it in your bag. The hooked rubber bottom connector is flexible to 90 degrees while the slim 2000 mAh battery attaches the back of your phone or case with an array of suction cups, so it fits most phones even with their cases on. Comes in both micro-USB connector or Apple Lightning connector versions.
