Charging method and terminal equipment

The invention provides a charging method and a terminal device, which are beneficial to ensuring that the terminal device is charged in a quick charging mode after a special quick charger is switched on again in case of power failure interruption, and can improve the charging efficiency so as to improve the user experience. The method comprises the following steps: detecting whether a voltage bus VBUS has a signal or not; under the condition that the VBUS has the signal, detecting whether the data positive signal line DP and the data negative signal line DM have the signal or not; detecting the type of the external equipment under the condition that both the DP and the DM have signals; under the condition that the type of the external equipment is the charger type, determining whether the port of the external equipment is a special fast charging port or not; under the condition that the port of the external equipment is the special fast charging port, detecting whether the voltage of the external equipment is
