1. A display apparatus, comprising:
an external input port which is connectable with an external apparatus, the external input port being configured to supply power to the external apparatus;
a power supply configured to (i) generate direct current power corresponding to a power consumption of the external apparatus when using power received from an external source, and (ii) provide the generated direct current power to the external input port;
a display;
a communication interface;
at least one memory; and
at least one processor connected to the external input port, the power supply, the display, the communication interface, and the at least one memory;
wherein the at least one memory includes programs, where the at least one memory and the programs are configured, with the at least one processor, to cause the apparatus to at least:
obtain, from the display, first power consumed in the display based on brightness information of the display,
determine second power suppliable to the external input port based on the first power consumed,
receive information, via the external input port from an external apparatus connected to the external input port, about third power supplying to the external apparatus,
determine fourth power supplied to the external input port, based on the second power and the information about the third power,
determine an over current protection (OCP) value based on the fourth power,
supply the determined fourth power, via the external input port, to the external apparatus, and
stop power supplied, via the external input port, to the external apparatus based on a determination that a current value, which is supplied to the external input port, exceeds the OCP value,
wherein the at least one processor is further configured to determine the OCP value according to a pre-set ratio from the current value supplied to the external input port according to the fourth power, and
wherein the pre-set ratio corresponds to an OCP margin, the OCP value is obtained by applying the pre-set ratio to the current value, and the OCP value is higher than the current value.
