1. A wireless charging device, comprising:
- a first charging unit configured to charge a first electronic device using a first wireless charging protocol, the first charging unit located on a first plane within the charging device;
a second charging unit configured to charge a second electronic device using a second wireless charging protocol, the second charging unit located on a second plane parallel to the first plane;
a shield arranged between the first and second charging units, the shield located on a third plane parallel to the first and second planes, wherein the first charging unit is located on an opposite side of the shield from the second charging unit, wherein the shield absorbs a magnetic field generated by at least one of the first charging unit and the second charging unit; and
a controller that disables power supply to the first charging unit in response to the second charging unit being positioned above the first charging unit and disables power supply to the second charging unit in response to the first charging unit being positioned above the second charging unit.

14. A program product comprising a non-transitory computer readable storage medium that stores code executable by a processor, the executable code comprising code to perform:
-
detecting, via a sensor, an arrangement of a first output coil and a second output coil of a wireless charging device, the first output coil being located in a first plane within the wireless charging device and the second output coil being located on a second plane parallel to the first plane; providing power to the first output coil and disabling power supply to the second output coil in response to the detected arrangement indicating the first output coil is positioned above the second charging coil; and providing power to the second output coil and disabling power supply to the first output coil in response to the detected arrangement indicating the second charging coil is positioned above the first output coil, wherein the first output coil charges a first electronic device using a first wireless charging protocol and the second output coil charges a second electronic device using a second wireless charging protocol, wherein the wireless charging device comprises a shield arranged between the first and second output coils, the shield located on a third plane parallel to the first and second planes, wherein the first output coil is located on an opposite side of the shield from the second output coil, wherein the shield absorbs a magnetic field generated by at least one of the first output coil and the second output coil. - View Dependent Claims (15, 16, 17)
