This ATT Fast-Charge Wireless Charging Pad (10W) charges up to 20% faster on select devices than standard wireless chargers thanks to its fast-charge adapter. For example, this device delivers a full charge after 3 hours and 30 minutes while others take 4 hours and 5 minutes. We all have days where half an hour feels like a lifetime. The Qi-certified wireless charging pad lets you simply put your phone on the pad for cable-free charging. Qi, pronounced "chee," is a universal wireless charging technology. The charging pad doesn't take up a lot of room, but it does deliver a lot of speed. It has an input of 5VDC/2A; 9VDC/1.67A with an output up to 10W on select devices and a charging distance of 6–8 mm. This powerful product comes complete with the Qualcomm Quick Charge 3.0 adapter charging pad and a 4.92 ft. (1.5-meter) micro USB power cable. It also comes with a 1-year limited warranty for additional peace of mind.
