The invention is suitable for the technical field of charging, and provides a charging device and a charging device control method, and the charging device comprises a power supply, a voltage output circuit, a control module, and a USB interface. The detection circuit comprises a plugging detection circuit and an MOS transistor connected in parallel with the plugging detection circuit. When the MOS transistor is in an off state and the control module detects that the voltage at the two ends of the plugging detection circuit is greater than a first preset value, the control module judges that the charging equipment is plugged into the USB interface and controls the MOS transistor to be conducted, and the USB interface outputs charging voltage to charge the charging equipment; and when the MOS tube is in a conducting state, the control module controls the MOS tube to reduce the driving voltage at preset intervals, and when the control module detects that the voltage at the two ends of the plugging detection cir
