ZAGG (www.zagg.com) has announced a new line of portable backup batteries for mobile devices. The Zagg Power Amp line features a fast-charging output technology called Quick Charge that instantly recognizes hundreds of devices and automatically delivers the fastest charge to each.
 
Along with the Quick Charge technology, the Zagg Power Amp line features pass-through charging, which lets users charge their devices quickly, even when the Power Amp itself is plugged in. The Zagg Power Amp line has a slim, sleek design, including a built-in LED flashlight and is available in capacities of 3,000mAh, 6,000mAh, 12,000mAh, and 18,000mAh.
