Quick Charging Method, Power Adapter and Mobile Terminal
First Claim
1. A method of quick charging for a mobile terminal configured for coupling with a power adapter via a Universal Serial Bus (USB) interface of the mobile terminal, comprising:
- sending, by the mobile terminal, a first instruction indicating that the mobile terminal is operable under a second charging mode to the power adapter through at least one data line in the USB interface, wherein the first instruction is configured for instructing the power adapter to adjust an output of the power adapter based on the first instruction, at least one power line located in the USB interface is configured for delivering electrical power from the power adapter to the mobile terminal to charge the mobile terminal, the at least one data line located in the USB interface is configured for establishing a bi-directional communication between the power adapter and the mobile terminal, the mobile terminal is selectively operable under a first charging mode or the second charging mode, and a charging current delivered by the at least one power line when the mobile terminal is operable under the second charging mode is greater than a charging current delivered by the at least one power line when the mobile terminal is operable under the first charging mode; and
receiving, by the mobile terminal, a charging current delivered by the at least one power line and corresponding to the second charging mode from the power adapter to charge a battery in the mobile terminal.
