Sydnee allows you to store and charge up to four devices at the same time. It simultaneously delivers a full charge to each iPad with 2.1 amps of power per device. Designed for iPad and compatible with iPhone, iPod touch, and other USB powered devices, Sydnee neatly charges and stores up to 4 of your iOS devices. The cable management system keeps cords organized and your iPads ready to go when you are. Sydnee’s “smart charge” feature detects which device is charging and how much power to supply to each.
