Abstract

A portable electronic device includes a first process control unit to send and receive a control signal, a battery electrically connected to the first process control unit to provide electrical power for the first process control unit, and a charging unit to charge the battery. The charge control unit comprises a charging procedure to control a work mode of the charging unit. A switch is electrically connected to the first process control unit and the charging unit to decide whether the charging unit works or not, and a first connecting port electrically connected to the first process control unit and the switch, to transmit a control signal, a digital signal and a power signal.

Claims
