Here’s a clever addition for Mophie, one of the longstanding battery case makers, which is now a part of the same smartphone accessory conglomerate as Zagg, Braven, iFrogz and InvisibleShield. The Juice Pack Connect is a modular take on the category, with a battery pack that slides on and off. For $80 you get a 5,400mAh battery (that should get you plenty of additional charge time) and a ring stand that props the phone up.
