    Abstract: Disclosed is an electronic device. A wireless power transferring device includes a first interface comprising interface circuitry, a conversion circuit, a coil, and a control circuit. The control circuit is configured to control the device to communicate with the power supply device to identify maximum supply power of the power supply device and set maximum transfer power to the maximum supply power or less based on the power supply device being connected to the first interface, to generate the transfer power based on power supplied from the power supply device using the conversion circuit, to transfer the generated transfer power to a wireless power receiving device using the coil, to determine whether the request is for power adjustment exceeding the maximum transfer power based on receiving a request for power adjustment from the wireless power receiving device, to adjust the transfer power using the conversion circuit in response to the request based on the request not being for power adjustment exceeding the maximum transfer power, and to ignore the request to adjust the transfer power based on the request for power adjustment exceeding the maximum transfer power.
