Claim:
1. A charger for charging a terminal, comprising: a power supply device configured to output a direct current (DC) charging current by rectifying and reducing a voltage of an input alternating current (AC), the power supply device including a voltage output port and a feedback receiving port, the voltage output port being configured to output the DC charging current, the feedback receiving port being configured to receive a feedback signal to adjust the output DC charging current; a charging port configured to connect to the terminal, and to output the DC charging current from the power supply device to the terminal, the charging port including a power supply port and a data signal port, the power supply port being connected to the voltage output port and configured to output the DC charging current to the terminal; a charging control device; and a switch device provided between the feedback receiving port and the charging port, and configured to connect the feedback receiving port to the power supply port or the data signal port according to control of the charging control device, wherein: when the charger is in a proximal feedback state, the switch device connects the feedback receiving port to the power supply port according to the control of the charging control device; and when the charger is in a distal feedback state, the switch device connects the feedback receiving port to the data signal port according to the control of the charging control device.
