Abstract
This disclosure provides a mobile terminal, a DC-charging power source adaptor, and a rapid charging method, which are proposed for a power source adaptor outputting dynamically adjustable voltage, where core voltage of a battery is divided into several intervals, and further in a segmented constant-current-like charging mode, a volt value of charging voltage output by the power source adaptor is adjusted dynamically according to the interval in which the core voltage of the battery in the mobile terminal while the battery is being charged lies, and the battery is DC-charged directly using the charging voltage output by the power source adaptor.
