7. A terminal, characterized in that the terminal comprises the reverse wired charging circuit of any of claims 1 to 2, the terminal comprising:
the prompting module is used for responding to the wired connection between the connector of the reverse wired charging circuit and the charged equipment and displaying prompting information, and the prompting information is used for prompting a user to select a data transmission mode or a reverse charging mode;
and the circuit switching module enables the switching circuit to be switched to the data transmission line or the reverse charging circuit of the reverse wired charging circuit due to selection based on a user.
8. The terminal of claim 7, wherein the circuit switching module enables the switching circuit to switch to the data transmission line or the reverse charging line of the reverse wired charging circuit based on a user selection in the following manner:
judging whether a user selects a reverse charging mode or not;
enabling the switching circuit to switch to a reverse charging circuit of the reverse wired charging circuit when the user selects a reverse charging mode;
the switching circuit is not enabled when the user does not select the reverse charging mode.
9. The terminal according to claim 7 or 8, characterized in that the terminal further comprises:
the reset module enables the switching circuit to recover to a state before switching due to the fact that the connector of the reverse wired charging circuit is in response to the fact that the wired connection with the charged device is terminated.
10. A terminal, comprising:
a memory to store instructions; and
a processor; instructions for invoking the memory store perform the reverse wired charging control method of any of claims 3-6.
11. A computer-readable storage medium storing computer-executable instructions that, when executed by a processor, perform the reverse wired charging control method of any one of claims 3-6.
