1. An electronic device that is operable in a wireless charging system with at least first and second additional electronic devices, the electronic device comprising:
a coil that is configured to receive wireless power signals from the first additional electronic device;
rectifier circuitry that is configured to convert the wireless power signals to direct current power; and
control circuitry that is configured to:
while the coil is inductively coupled to the first additional electronic device without the coil being inductively coupled to the second additional electronic device, assign addresses to the first and second additional electronic device; and
using the coil, communicate with the first and second additional electronic devices using the addresses.
