Abstract:
An apparatus for receiving wireless power is provided. The apparatus a communication circuit configured to transmit a first indication of a first wireless charging category associated with the apparatus. The communication circuit is further configured to receive an indication of a wireless charging class of a power transmit unit (PTU). The communication circuit is further configured to transmit a second indication of a second wireless charging category associated with the apparatus based on the wireless charging class of the PTU being compatible with a higher wireless charging category than the first wireless charging category. The apparatus further comprises a coupler configured to receive a level of wireless power corresponding to the second wireless charging category. The higher wireless charging category indicates an ability to receive a greater amount of wireless power than the first wireless charging category.
