QUICK CHARGING METHOD, POWER ADAPTER AND MOBILE TERMINAL
First Claim
1. A quick charging method, wherein, the method is applied to a power adapter, the power adapter is coupled to a mobile terminal through a universal serial bus (USB) interface, a power line in the USB interface is used by the power adapter to charge the mobile terminal, a data line in the USB interface is used by the power adapter to conduct a bidirectional communication with the mobile terminal, and the power adapter supports a common charging mode and a quick charging mode, wherein a charging current of the quick charging mode is greater than that of the common charging mode;
- the method comprises;
conducting by the power adapter a bidirectional communication with the mobile terminal through the data line in the USB interface so as to determine to charge the mobile terminal in the quick charging mode; and
adjusting by the power adapter a charging current to a charging current corresponding to the quick charging mode so as to charge the mobile terminal.
