1. An electronic apparatus comprising at least one processor and/or at least one circuit which function as:
a connection unit configured to be connected to an external apparatus;
a conversion unit configured to convert an input voltage supplied from a power supplying apparatus into an output voltage that is 1/N times the input voltage, 1/N being predetermined (where N>1), and the output voltage from the conversion unit being output from the connection unit to the external apparatus in a case where the external apparatus has been connected to the connection unit; and
a control unit configured to request the power supplying apparatus for a third voltage that is N times a first voltage,
wherein
in a case where the third voltage has been supplied from the power supplying apparatus in response to the request for the third voltage, the conversion unit converts the third voltage into the first voltage, and the first voltage is output from the connection unit, and
in a case where the external apparatus is connected to the connection unit after the control unit has requested the power supplying apparatus to supply the third voltage, the control unit performs communication with the external apparatus, and requests the power supplying apparatus to supply a fourth voltage that is N times a second voltage in response to receiving, from the external apparatus via the communication, an instruction for setting the second voltage as a voltage to be output from the electronic apparatus to the external apparatus, the second voltage being higher than the first voltage.
