PowerIQ technology intelligently communicates with connected devices to maximize both compatibility and charging speed (up to 2 Amps).
6000 mAh of capacity and an energy efficiency rate 10% above previous generation Astros and many current standard alternatives charges the iPhone three times and large-capacity phones like the Galaxy S4 almost twice.
A "shake" starts a charge or displays the remaining power level. The ultra-low power consumption (100000 shakes consume less than 1%) 10-LED power meter balances accuracy and aesthetics.
Sturdy construction and matte finish withstand bumps and drops. Grade A cells and premium chips ensure reliability. Input: 5V / 1A; Use a 1A adapter (not included) with the included USB cable for the fastest charging time (6 hours).
