CHARGING APPARATUS

This application discloses a charging apparatus, a charging method, and an electronic device, and pertains to the field of electronic technologies. The charging apparatus includes a housing, a first charging coil, a device detection module, and a coil adjusting module. The first charging coil, the device detection module, and the coil adjusting module are all disposed in the housing. The device detection module is connected to the coil adjusting module and configured to detect a device type of a to-be-charged device placed on an outer surface of the housing to obtain target device type information, and send the target device type information to the coil adjusting module. The coil adjusting module is connected to the first charging coil and configured to adjust a size of the first charging coil based on the target device type information, enabling an adjusted size of the first charging coil to match a size of a second charging coil in the to-be-charged device.
