1. A display device comprising:
a power supply configured to supply power;
an external input port;
a display; and
at least one processor configured to:
acquire brightness information of the display,
identify first power information required from the display based on the acquired brightness information,
receive third power information from an external device connected to the external input port, wherein the third power information includes information on voltage and current values required for charging the external device, and
adjust power supplied to the external input port based on the first power information, second power information supplied from the power supply, and the third power information,
wherein at least one processor is configured to:
based on power required from the external device that is calculated based on the voltage and current values not exceeding power available, control supply of power to the external input port at the voltage and current values included in the third power information, and
based on the power required from the external device exceeding the power available, control supply of power to the external input port at specified voltage and current values within a range of values that does not exceed the power available, and
wherein at least one processor of the device is configured to:
based on the display device being in a power saving mode, adjust the power supplied to the external input port based on default power information corresponding to the power saving mode of the display device and the second power information,
adjust the power supplied to the external input port to a threshold power based on the display device switching from the power saving mode to a normal mode, and
control the display to display an image corresponding to the normal mode.
