The first input terminal 1 is a Type-C interface, which can be used to connect electronic devices for Type-C interfaces, such as mobile phones, tablet computers, etc. The second input terminal 2 is a Lightning interface, which is used to connect electronic devices with Lightning interfaces. When an external electronic device is connected to the first input terminal 1, the control module 5 determines that an external electronic device is connected to the first input terminal 1 according to preset data (for example, the input voltage value), controls the third control unit 43 to turn on, controls the second control unit 42 to turn off, and then controls the S2 pin and D2 pin of the first control unit 41 to turn on through the third control unit 43.

At the same time, the control module 5 controls the gate of the second control unit 42 to be G1 not turned on. At this time, the second control unit 42 is in the off state, and then controls the first MOS transistor of the first control unit 41 to be turned off, so that the device connected to the second input terminal 2 cannot be charged.

[0037] In one embodiment, the charging module 6 includes a voltage conversion unit 61. Thus, the input voltage is converted into a power supply voltage of the control module 5 by the voltage conversion unit 61.
