Claims

1-5. -5. (canceled)

6. A charger for charging a mobile terminal, wherein the charger and the mobile terminal both have a Type-c port, the charger identifies the type of the mobile terminal and is configured as Power Delivery charging mode or user-defined charging mode according to the identification result.

7. The charger according to claim 6, wherein the Type-c port comprises a C+ terminal, a C−

terminal, a Dp terminal, a Dm terminal and a Vbus terminal, the charger comprising;

an identification processor connecting the C+ terminal and the C−

terminal, configured to identify the type of the mobile terminal;

a protocol processor, configured to execute the user-defined charging mode;

a connection unit, configured to be connected between the protocol processor and the mobile terminal;

a load switch unit configured to connect the Vbus terminal, such that when the identification processor detects the mobile terminal, a bus switch is turned off,

wherein when the mobile terminal is of a first type, the identification processor controls the connection unit to connect the protocol processor to the Dp terminal and the Dm terminal;

when the mobile terminal is not of the first type, the identification processor controls the connection unit to make the Dp terminal and the Dm terminal short-circuit.

8. The charger according to claim 6, wherein the connection unit comprises a first selective switch, a second selective switch and a common node, wherein the first selective switch connects the Dp terminal to the D+ terminal or the common node, and the second selective switch connects the Dm terminal to the D−

terminal or the common node.

9. The charger according to claim 8, wherein when the mobile terminal is of the first type, the first selective switch and the second selective switch respectively connect the Dp terminal and the Dm terminal to the common node;

when the mobile terminal is not of the first type, the first selective switch connects the Dp terminal to the D+ terminal, and the second selective switch connects the Dm terminal to the D−

terminal.

10. The charger according to claim 6, wherein the user-defined charging mode comprises Quick Charge charging mode and Pump Express plus charging mode.

11. The charger according to claim 7, wherein the user-defined charging mode comprises Quick Charge charging mode and Pump Express plus charging mode.

12. The charger according to claim 8, wherein the user-defined charging mode comprises Quick Charge charging mode and Pump Express plus charging mode.

13. The charger according to claim 9, wherein the user-defined charging mode comprises Quick Charge charging mode and Pump Express plus charging mode.
