The present invention relates to a network access device and a method of processing data in a network access device, and more particularly to a network access device which can classify unnecessary packets of data packets transmitted through a communication network and charges electric power by using the unnecessary packets to use the electric power in the network access device, thereby saving energy, and a method of processing data in a network access device. A network access device connected to a communication network includes: a reception unit for receiving a data packet through the communication network, a packet determining unit for receiving the data packet received from the reception unit to recognize a destination address of the data packet, and setting the data packet as a charging data packet if the destination address of the data packet does not coincide with a destination address set in advance after comparing the destination address of the data packet with the set destination address, a power charging unit for receiving a charging data packet from the packet determining unit and charging electric power by using an electrical signal of the charging data packet, and a power supply unit for receiving electric power from the power charging unit and supplying electric power to the network access device.
