Are you seriously trying to lead us into the totally unrealistic misapprehension that one would in any way be able to plug 334 4 way extention leads into a socket and expect it to work with reliability and safety?
not into a socket. Into each other.
though your room might not have enough space,
the fuse in the first plug that goes into the socket will be no more than a nominal 13A
the effects would be not different to have a single multiway adaptor, and plugging several things into it. Say, a kettle, a toaster, a washing machine, a tumble drier, a phone charger, and a fan heater. What will happen if you turn them all on together?
Why do you think that spreading them over more than one multiway will be different?
And what if you just plug a lot of phone chargers into it?
