16. A method of operating a wireless power transmitter comprising (i) an inverter that is operable to produce an alternating current (AC) signal based on a direct current (DC) voltage signal and a drive signal, (ii) a tuning circuit comprising one or more capacitors that is operable to tune the AC signal, and (iii) a transmission antenna that is operable to produce a wireless signal for receipt by at least one receiver antenna of at least one wireless power receiver in accordance with the AC signal that is produced by the inverter and tuned by the tuning circuit, the method comprising:
determining a coupling between the wireless power transmitter and a given wireless power receiver;
receiving, from the given wireless power receiver, a communication indicating a selected power mode for wireless transmission, wherein the selected power mode is selected based on the coupling between the wireless power transmitter and the given wireless power receiver; and
in response to receiving the communication from the given wireless power receiver, causing the wireless power transmitter to begin operating in accordance with the selected power mode.
