ABSTRACT:
A terminal for a power supply system is disclosed. The terminal may have a connection portion, a battery that receives power from an external device via the connection portion, and a detector that detects a data signal from the external device. The terminal may also have a determination unit, a current converter that selectively converts an amount of charging current from a first current to a second current larger than the first current, and a controller that controls charging of the battery on the basis of a determination result. The controller is configured to control the current converter to charge the battery with the first current when the determination unit determines the external device is not a dedicated power supply, and to control the current converter to charge the battery with the second current when the determination unit determines the external device is a dedicated power supply.
