Anker Astro3 12000mAh External Backup Battery Charger
The more power, the better. Packed with 12000mAh of energizing juice, and featuring an energy efficiency rate 10% above previous generation, the new Anker Astro3 external backup battery pack charges the iPhone six times and large-capacity phones like the Galaxy S5 almost four times.
Out of the three USB charging ports on the Astro3, one smart charging port powered by Power IQ technology, intelligently identifies each connected device and speaks its language - guaranteeing the fastest charge time for every device. Two additional ports charges Android smartphones at full speed. (Max speed of 4 Amps among 3 ports). 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.
