A mobile terminal is provided that includes a body to be mountable to a first charging apparatus, a current generator to generate an induction current by using a current of the first charging apparatus, and a wireless charger between the current generator and the battery to charge the battery by converting the induction current into a direct current. The mobile terminal may also include a connection port to be electrically connected to the battery and being connectable to a power supply terminal of a second charging apparatus, and a power charging controller to disconnect an electrically connected status between the wireless charger and the battery when the power supply terminal is electrically connected to the connection port.

Mobile terminal

A method of determining a charger of a mobile terminal, and which includes receiving, via a controller of the mobile terminal, a connection signal indicating the charger is connected to the mobile terminal; setting, via the controller, a charging current of the charger for charging the mobile terminal and increasing the set charging current in predetermined current units; measuring, via the controller, an actual current received from the charger and applied to the mobile terminal; comparing, via the controller, the set charging current with the measured actual current; determining, via the controller, a charging sector of the charger when the set charging current is larger than the measured actual current for a first predetermined amount of time; and calculating a charging current capacity of the charger using the determined charging sector.
