The ZAGG Sparq Portable Battery and Wall Adapter is the durable, most stylish solution for portable power. It features built-in prongs, eliminating the need for a separate charging cable; and, unlike many other portable chargers, it has an on/off switch to help preserve stored power when it's not in use. Five bright LEDs quickly and clearly show its remaining power supply while its USB port(s) allow for nearly universal charging.
Stored power allows you to fully charge your favorite devices multiple times.
