摘要： A portable electronic device includes a system chip, an enabling switch, a signal conversion circuit, a power switching circuit, a storage medium and a synchronous processing module. The enabling switch is triggered to issue an analog signal. The signal conversion circuit converts the analog signal into a digital control signal. The power switching circuit selects one of multiple power sources to be outputted as a voltage signal. The storage medium receives the voltage signal. The synchronous processing module is electrically connected to the system chip, the storage medium, the signal conversion circuit, the power switching circuit and the transmission line. In response to the digital control signal, the storage medium is communicated with an external electronic device through a transmission line, so that the storage medium of the portable electronic device is used as an external storage medium of the external electronic device.
