1. An electronic apparatus comprising:
a connection unit that connects to a power source device and an external apparatus;
a power control unit that controls power input from the power source device and power output to the external apparatus;
a voltage conversion unit that steps up or steps down voltage of the power input from the power source device;
a setting unit that sets a path through which the power input from the power source device is output to the external apparatus; and
a control unit that acquires attribute information of the power source device and required voltage of the external apparatus and, performs control, based on the attribute information and the required voltage, to switch between a path through which the power input from the power source device is output to the external apparatus via the voltage conversion unit, and a path through which the power input from the power source device is output to the external apparatus not via the voltage conversion unit,
wherein the power source device includes a first power source device and a second power source device,
wherein the connection unit includes a first input terminal connected to the first power source device, a second input terminal connected to the second power source device, and an output terminal connected to the external apparatus,
wherein the voltage conversion unit includes a first voltage conversion unit that converts first input voltage of the first input terminal into voltage required for operating a component of the electronic apparatus and converts second input voltage of the second input terminal into voltage required for operating a component of the electronic apparatus, and a second voltage conversion unit that converts the first input voltage of the first input terminal into output voltage of the output terminal and converts second input voltage of the second input terminal into output voltage of the output terminal, and
wherein the control unit performs control to switch to a path through which the first input voltage of the first input terminal or the second input voltage of the second input terminal is output to the output terminal via the second voltage conversion unit, or to a path through which the first input voltage of the first input terminal or the second input voltage of the second input terminal is output to the output terminal not via the second voltage conversion unit.
