How it's used
Refers specifically to an extension cord with multiple outlets, which is a common household necessity in Hong Kong apartments where wall sockets are often limited. It is a functional, everyday term that replaces the more formal or technical descriptions used in other regions. When buying one, you might also hear people refer to the number of sockets as a 'three-pin' or 'multi-socket' version.

Common mistake
Do not confuse this with the Mandarin term 插線板 or 接線板, as those are not used in daily Cantonese conversation. Also, avoid using it to describe a simple extension cable with only one socket, which is usually just called a 延長線.
