Mophie's just released the Juice Pack Air promising it'll do just that thanks to a 1,700 mAh backup battery embedded in the edge-to-edge case, only two weeks after launching the slender Juice Pack Helium with a 1,500mAh battery. On top of an extra 10 hours of 3G talk time and edge-to-edge protection, Mophie's touting lightning pass-through capability, enhanced sound thanks to its speaker redirection, an LED battery indicator and faster charge times thanks to a 1A charging upgrade. You'll be able to grab it in black now, with the red and white color options shipping by March 22nd. For more info, check the video and PR after the break.
