Abstract: A power supply terminal, and a charging control method are disclosed. The power supply terminal includes a USB port, a switch, a power source module, and a processor, where the USB port is configured to connect to a power receiving terminal; one end of the power source module is connected to a power source pin VBUS of the USB port and is configured to charge the power receiving terminal by using the power source pin VBUS; a first end of the switch is connected to the data pin D+ and a second end of the switch is connected to the data pin D−; when the switch is on and the processor detects that a drop amplitude of the output voltage of the power source module exceeds a preset value, in a process in which the power source module outputs a voltage to charge the power receiving terminal.
