ABSTRACT:
Disclosed is a charging apparatus capable of easily charging a battery of a mobile communication terminal and being portable. The charging apparatus includes a first connector having a power supply terminal similar to a power supply terminal of a data communication connector, the first connector being connected to a data communication connector of a supplying side mobile communication terminal supplying charge power; and a second connector having a power supply terminal similar to the power supply terminal of the data communication connector, the second connector being connected to a data communication connector of a receiving side mobile communication terminal receiving the charge power; a charging controller for charging a battery of the receiving side mobile communication terminal by supplying the charge power inputted from the power supply terminal of the first connector to the battery of the receiving side mobile communication terminal through the power supply terminal of the second connector until a battery voltage level of the receiving side mobile communication terminal reaches a charge voltage level set by a user; and a switch switched by the user's operation for connecting and disconnecting a path of supplying the charge power between the power supply terminal of the first connector and the charging controller.
