A current electronic distributing device that can limit maximum output currents of a plurality of input/output (I/O) ports to a first current or a second current. The current electronic distributing device includes a plurality of current detection units, a plurality of current limiting units, a control unit, and a power supply unit. The power supply unit supplies power to the current electronic distributing device. Each of the current detection units respectively detects consumption currents of each of the I/O ports. The control unit calculates a sum of the consumption currents of the plurality of I/O ports, and controls each of the current limiting units to limit the maximum output currents of each of the I/O ports to the first current or the second current according to the sum of the consumption currents of the plurality of I/O ports.
