The fast charge power of the wireless charger depends on the specifications of the charger itself and the compatibility of the device for wireless charging. At present, most wireless chargers support 5W, 7.5W, 10W, 15W, 20W and other different power fast charge protocols. Among them, 5W and 7.5W are the more common power, suitable for most smartphones. 10W, 15W and 20W power is suitable for mobile phones that support higher power fast charge. Therefore, the fast charge power range of wireless chargers ranges from 5W to 20W, and the specific degree of support depends on the specific charger model and device model.
