ELECTRONIC DEVICE FOR POWER CONTROL, OPERATION METHOD THEREOF, AND STORAGE MEDIUM

An electronic device is provided. The electronic device includes a battery, a first connector to which a first external power supply device is connectable, a second connector to which a second external power supply device is connectable, a charging circuit configured to supply, to the battery, power received using at least one of the first connector and the second connector, and a control circuit, wherein the control circuit is configured to in case that a connection of the first external power supply device is detected via the first connector, identify first power information of the first external power supply device, at least based on the first power information, control the first external power supply device to supply power to the charging circuit via the first connector at a first voltage, in case that a connection of the second external power supply device is detected via the second connector while the power is being received at the first voltage via the first connector, identify second power information of the second external power supply device, based on the first power information and the second power information, determine a power ratio between the first external power supply device and the second external power supply device, and adjust an output voltage of at least one of the first external power supply device and the second external power supply device such that a ratio between a first amount of power supplied from the first external power supply device and a second amount of power supplied from the second external power supply device corresponds to the determined power ratio.
