In the wireless charger, a control circuit may control a communication circuit of the wireless charger so as to, on the basis that the communication circuit of the wireless charger receives a first request message for requesting the lowering of an output voltage of a power signal outputted to the power receiving device through a coil of the wireless charger, output, to the power supply device through a data terminal of the wireless charger, a second request message for requesting the lowering of an input voltage of a power signal inputted from the power supply device through a power terminal of the wireless charger. The control circuit may control the communication circuit so as to, on the basis that the communication circuit receives a third request message for requesting the raising of the output voltage, output, to the power supply device through the data terminal, a fourth request message for requesting the raising of the input voltage.",
