Plug Plus / plug

When all plugs are put into the outlets and you have more plugs to put, what would you do?

You would probably busy look for multi-tab or other outlets, right?

Because of the limited outlets, this issue was impossible to overcome without multi-tabs
‘Plug plus’ is designed with flexibility. There are holes at the rear head of the plug,
so users can put plug into the back of another plug. No more searching for the multi-tabs and outlets!
Users can connect as many plugs as they want, the recently connected plug gets same amount of
electricity as it is from the previous plug.
