An electronic device comprises a processor, a charging port, and memory that stores program code. When the program code is executed by the processor, the electronic device charges a battery of the electronic device using the charging port when a charger is connected to the charging port, stops charging in response to detecting that the charging port is abnormal, and displays a first window on a display interface of the electronic device in response to detecting that the charging port is abnormal. The first window comprises a first prompt information and a second prompt information. The first prompt information is used to prompt that liquid intake exists in the charging port, and the second prompt information is used to prompt a user to exclude a liquid intake situation of the charging port.

Charging method and related device

A charging method and a related device are provided. A charge protection apparatus includes a micro control unit MCU, a current detection circuit, a gating circuit, and an I/O interface. The current detection circuit detects an external charging current flowing through a power cable. The current detection circuit transmits the external charging current to the MCU. The MCU transmits the external charging current to a user terminal by using the I/O interface, so that the user terminal calculates a current difference between the external charging current and an internal charging current detected by the user terminal, and determines, based on the current difference, whether to generate a circuit control command. The MCU receives the circuit control command sent by the user terminal, and controls, according to the circuit control command, the gating circuit to be in a closed state or an open state.

The present invention discloses an anti-shedding power cable plug, comprising a power cable and a plug body. The plug body includes a hollow housing, the housing includes a lower housing and an upper housing, and the housing accommodates a lock insert and conductive pins. The lock insert includes an inner sleeve, a stepped groove is arranged in the middle of the inner sleeve, a supporting protrusion is arranged on the outer side of the stepped groove, a first rotating hole is arranged transversely on the inner side of the stepped groove. In the present invention, the anti-shedding hook enables the power cable plug to be locked on the socket, thereby preventing the power cable from shedding during use so as to improve the reliability.
