The invention provides an electronic device, which is electrically connected with a power supply device. The electronic device comprises a display unit and a base unit comprising a housing, a circuitboard and a system connector. The system connector comprises a system input end portion, a system positive electrode end portion, a system negative electrode end portion, a plurality of system positive electrode wires, a plurality of system negative electrode wires and a system detection wire. The system input end portion is arranged corresponding to an opening of the housing. The system positiveelectrode end portion and the system negative electrode end portion are electrically connected with the circuit board. The system positive electrode wires are connected between the system input end portion and the system positive electrode end portion. The system negative electrode wires and the system detection wire are connected between the system input end portion and the system negative electrode end portion. The orthographic projections of the system input end portion, the system positive electrode end portion and the system negative electrode end portion on the housing are not overlapped.
