Abstract: A power supply adapter according to one aspect of the present disclosure includes a power cord, a power-source attachment portion, a working-machine attachment portion, a temperature detector, and an overheat determiner. The temperature detector is configured to detect temperature of the power cord and to output a detection signal indicating the temperature detected. The overheat determiner is configured to determine that the power cord is in an overheated state based on the detection signal from the temperature detector and to output an overheat determination result indicating that the power cord is in the overheated state.

Abstract: An electric device in one aspect of the present disclosure comprises a connector, a power supply unit, a connection-detection unit, and a control unit. The control unit is configured to control electric power supplied to the power supply unit from a battery so as to increase electric power supplied to the power supply unit when the connection-detection unit detects that an external device is connected to the connector.
