Just watch for the spacing of the sockets on the cheaper extensions.
Many wall warts are wider/longer than a standard plug.

Not many are wider these day with the demise of the iron transformer.


Longer can be a problem, quite a few have the outlet wire coming from
the end adjacent to the earth pin not from the L & N pin end like a
normal flex.

I have a theory about that. I think the Chinese have the idea that our
13A socket is normally mounted earth pin downwards.

If you are unconvinced, look at the label orientation on these warts.

Perhaps the Chinese mount their OWN 13A sockets that way up? After all,
while far from universal, they are one of the Chinese standards. (So I
have read - never actually been there!)

Insofar as 13A was the Hong Kong standard, they are a Chinese standard.
