Claim 11:
12. A method comprising:
detecting, by a wireless charger having multiple power transmission coil segments, two or more devices to be charged that are respectively located proximate different power transmission coil segments of the wireless charger;
determining, by the wireless charger, a charging timeout period for at least one of the two or more devices;
determining, by the wireless charger, timing for alternating between charging the two or more devices so that, when alternating between charging the two or more devices, a time period in which the coil segment for a device is not activated is less than the charging timeout period for the device;
applying, by the wireless charger, a drive signal to the power transmission coil segments, the power transmission coil segments being coupled in series with each other; and
in response to detecting the two or more devices, selectively bypassing the power transmission coil segments, by the wireless charger, to alternate between charging the two or more devices according to the determined timing.
