All I can add is that it appears to be unclear whether a roof-top photovoltaic array on domestic premises is a "fixed installation" within the EC EMC Directive definition. The UK authorities say it is not - presumably for the common-sense view of John Allen that it is unreasonable to make a homeowner a "Responsible Person". If a PV array is not a "fixed Installation" then it is inconceivable that a humble socket/charger is such. So I do not really believe my original proposal is valid. But then this is a weekend discussion.
It appears, however, that at least some parts of the EC believe that a roof-top photovoltaic array on domestic premises is a "fixed installation" ......unless this list knows better! .... BTW The UK wiring regulations BS7671:20+Amdt. 3:2015 seem to think that all a "Responsible Person" has to do in connection with a "fixed installation" is to check that it was properly installed and keep on file the manufacturer's paperwork, so perhaps the burden of a permanently wired-in USB charger categorised as a "fixed installation" is not too severe.

I agree up to a point.

The CE mark can't be applied because it's prohibited on mains plugs and sockets.

See above; it just raises further unresolvable issues. What we should be pressing for is an applicable standard, not trying to hammer existing standards into applicability. -- OOO - Own Opinions Only. With best wishes.
