Zusammenfassung:	A charger includes a first universal serial bus (USB) interface; an AC/DC module, a gating module, and a first control module. The AC/DC module is configured to convert an AC voltage to a DC voltage, and output at least two charging voltages. The gating module is configured to selectively connect to an output end corresponding to the charging voltages. The first control module is configured to control, according to level states of a positive data line end and a negative data line end of the first USB interface, the gating module to select an output end.
