POWER ADAPTER AND TERMINAL
First Claim
1. A power adapter comprising a power conversion unit and a charging interface, the power conversion unit configured to charge a terminal via the charging interface, the power adapter further comprising:
- a communication unit, configured to perform bi-directional communication with the terminal via the charging interface to determine a charging mode of the terminal; and
at least one of a voltage control unit and a current control unit, configured to control at least one of an output voltage and output current of the power conversion unit according to the charging mode determined by the communication unit.

Abstract
A power adapter and a terminal, and the power adapter includes a power conversion unit and a charging interface, the power conversion unit charging the terminal via the charging interface, and the power adapter further includes a communication unit, for performing bi-directional communication with the terminal via the charging interface to determine a charging mode of the terminal, and a voltage control unit and/or current control unit, for controlling the output voltage and/or output current of the power conversion unit according to the charging mode determined by the communication unit. The power adapter negotiates with the terminal about the charging mode through the communication unit, and the output voltage/output current of the power adapter is controlled according to the charging mode determined by the communication unit.
