  • Patent number: 10224734
    Abstract: The present invention provides a charging system that includes a charging adapter and a mobile terminal. The charging adapter includes: a second USB interface; and an adjusting circuit for rectifying and filtering the mains supply to obtain an original power signal, for performing a voltage adjustment on the original power signal, and for outputting a power signal after the voltage adjustment. The mobile terminal includes a first USB interface. P first power wires in the first USB interface and P second power wires in the second USB interface are correspondingly coupled, and Q first ground wires in the first USB interface and Q second ground wires in the second USB interface are correspondingly coupled. Because each first power wire and a corresponding second power wire are coupled, at least two charging circuits can be provided, and the charging system supports charging with a large current more than 3 A.
