TERMINAL WITH TWO CHARGING CIRCUITS

A terminal (10) is provided, which comprises a charging interface (11), a first charging circuit (12) coupled with the charging interface and receives an output voltage from an adapter and applies the output voltage to both ends of multiple cells (13) connected in series in the terminal to charge the multiple cells, and a second charging circuit (61) that comprises a step-up circuit (62), the step-up circuit coupled with the charging interface and with the multiple cells, the step-up circuit receives the output voltage of the adapter via the charging interface, steps up the output voltage of the adapter to a second voltage, and applies the second voltage to both ends of the multiple cells for charging, wherein the first charging circuit is operable in a quick charging mode, the second charging circuit is operable in a normal charging mode, and the terminal further comprises a control unit (71) performing two-way communication with the adapter to determine a charging mode, and switching between the first charging circuit and the second charging circuit upon determining whether the terminal will be charged with the quick or normal charging mode.
