No need for hassle with cables. Just place your device on the wireless charger, and it immediately starts charging.
Qi is a global standard that makes wireless charging possible for your device.
Qi works using magnetic induction, and is currently designed for devices that use 5 watts of power or less, such as mobile phones.
Qi chargers and devices use the same frequency. As long as their charging areas are touching, all Qi products are compatible, regardless of manufacturer or brand.
