Abstract: A mobile terminal including a terminal body comprising a battery; an adaptor connector formed at one side surface of the terminal body and to which a power supply adaptor is connected; a plurality of charging units configured to charge the battery between the adaptor connector and the battery; and a controller configured to generate a control signal for controlling each of the plurality of charging units. Further, any one of the plurality of charging units is configured to detect a level of a voltage of the battery, compare the voltage of the battery with first to third threshold voltages, and output first battery voltage data to the controller when the voltage of the battery is lower than the first threshold voltage, output second battery voltage data to the controller when the voltage of the battery is equal to or larger than the first threshold voltage and is lower than the second threshold voltage, and output third battery voltage data to the controller when the voltage of the battery is equal to or larger than the second threshold voltage and is lower than the third threshold voltage.
