Abstract: The disclosure discloses a mobile terminal, a DC-charging power source adaptor, and a charging method, where the mobile terminal detects whether two communication pins of a USB interface thereof are shorted, and if an inserted external device is a power source adaptor, then the mobile terminal communicates with the power source adaptor, so that the mobile terminal identifies automatically the type of the externally connected charging device. Also a specialized rapid charging mode is designed for a DC-charging power adaptor, so that a battery being charged routinely is DC-charged at large current using charging voltage output by the DC-charging power source adaptor, and a volt value of the charging voltage is adjusted dynamically to the varying voltage of the battery core.

Abstract: This disclosure relates to a DC-charging power source adaptor including a charging interface, an AC to DC converting unit, and a controlling unit; and the DC-charging power source adaptor is timed to communicate with a mobile terminal which is a charging object, to acquire a change in voltage of a battery in the mobile terminal and further adjust dynamically a volt value of charging voltage output by the DC-charging power source adaptor according to the change in voltage of the battery, and DC-charges the battery in the mobile terminal using the charging voltage.
