name for an electrical product and function

[kwokwai]

It has got a long electrical line and several sockets on it.
It can support all kinds of electrical applications.
Maximum load: 13A, and 250V

Is it called a trailing socket? :confused:

I don't know if it can support PC, Stereo, Scanner, and Printer together. :confused:

Called an "extension cord" here.
