3-meter copper cable extension for the multi-socket. The outlets are made of pure copper clips with strong elasticity - this ensures the clips do not become loose even after plugging and unplugging over 5000 times. The wire core of the socket conforms to international standards. It also has the overload protector which will cut off the power when there is excessive power to protect household appliances and sockets. An independent switch and power light in each layer, it could help save the usage of electricity. Includes two 2.1amp USB charger ports for charging all USB powered devices.
