A fast charging method, a mobile terminal (300) and a power source adapter (400). The method comprises: sending, by a mobile terminal (300), a first instruction to a power source adapter (400) through a data line in a USB interface, the first instruction being used for instructing the power source adapter (400) to start a fast charging mode; and receiving, by the mobile terminal (300), a charging current corresponding to the fast charging mode from the power source adapter (400) so as to charge a battery in the mobile terminal (300). Instead of blindly increasing an output current to conduct fast charging, the power source adapter (400) conducts fast charging on the mobile terminal (300) using a fast charging mode after receiving a first instruction of the mobile terminal (300), thereby improving the security of the fast charging process. |
