PURPOSE: A charging device and method thereof are provided to gradually amplify an input current value based on time, thereby preventing a voltage in the charging device from dropping at charging start time. CONSTITUTION: A power supply unit(100) supplies power to a charging device(200). A charging managing unit(210) manages the power of the charging device. The charging managing unit includes a charging controller(220), a charging circuit unit(230), and a current adjusting unit(240). The charging circuit unit performs a conversion function and a transfer function in the charging managing unit. A power charging unit(250) stores power transferred from the charging managing unit.
