Detects your device. Delivers the fastest charge.
Not all charging ports are created equal. Standard ports only charge some devices at full speed and others often really slowly. But with PowerIQ™ technology, each port intelligently identifies your device to deliver its fastest possible charge speed. So you save hours of time.

Uber-High Capacity
Packed with power, the 2nd Gen Astro holds enough power to charge most devices one or more times.
