An electronic/electric device is provided to supply a power to each part or element from a power supply unit and to charge a battery from a battery charging unit. An electronic/electric device includes a first power supply unit(220) to receive a power from an exterior and to generate and supply a power of a certain level to each part, at least two power terminals(261,262) contacting a contact terminal of a pad of an external base system, a memory(240) storing information of the device, and a power controller(210). The power controller transmits the information stored in the memory if the controller receives a signal of requesting the information via the charge terminals(271,272). The power controller supplies the power to the power supply unit if the power is inputted through the power terminal.
