Communication procedure, power adapter and terminal

摘要

Provided are a communication method, a power adaptor and a terminal. The method comprises: before a power adaptor charges a terminal, receiving handshake information from the terminal; according to the handshake information, determining, by the power adaptor, an initial charging parameter; and according to the initial charging parameter, charging, by the power adaptor, the terminal. In the embodiments of the present invention, before a power adaptor charges a terminal, the power adaptor receives handshake information from the terminal, and determines an initial charging parameter according to the handshake information, which can effectively avoid a phenomenon of the heating and even burnout of a mobile phone due to the fact that the voltage or current of the power adaptor is blindly increased.
