It's not that simple.  Indoors in the UK it's a BS1363 socket.  Outdoors on
a camp site it will most
likely be a CEE 17 blue single-phase.  But it's possible you might get CEE
17 red three-phase
in some situations.  I've a vague memory there are other connectors used in
marine applications.
Also, although BS1363 connectors are for indoor usage, it's possible to get
weatherproof
housings for external use.  So even in just the UK, if a camp site says
power hook-ups are
available you can't be sure what connector is used.  Most likely CEE 17
blue, but maybe not.

Things get worse in Germany and France, as far as the indoor connectors
go.  See
https://en.wikipedia.org/wiki/AC_power_plugs_and_sockets#CEE_7_standard
and try to guess what you might get in either country.  I expect they also
have weatherproof
housings for external use.

Hence power_supply=yes means there is a hook-up but the mapper doesn't know
what it is.
