The method 200 also includes establishing one of the first electrical device 110 and the second electrical device 115 as the power transmitter and the other of the first electrical device 110 and the second electrical device 115 as the power receiver (at block 220). The first electronic processor 120 and the second electronic processor 150 negotiate over the wireless connection established between the first electrical device 110 and the second electrical device 115. The first electronic processor 120 and/or the second electronic processor 150 determine which one of the first electrical device 110 and the second electrical device 115 is to be the power transmitter and the power receiver. In some embodiments, the first electronic processor 120 and/or the second electronic processor 150 determine the power transmitter and the power receiver based on a user instruction received via a user interface of the first electrical device 110 and/or the second electrical device 115.

The method 200 also includes converting, using a transmitter power conversion circuit, input power to AC power (at block 230). Following the above example, the first power conversion circuit 135 (for example, the transmitter power conversion circuit) converts power received from the power input 180 into an AC power. The method 200 further includes providing, using a transmitter control unit, alternating current to a transmitter coil (at block 240). For example, as described above, the first control unit 140 (for example, the transmitter control unit) provides alternating current from the first power conversion circuit 135 to the first coil 145.
