The CE mark has become a "CCCe" mark.

"Chinese Copied Ce" perhaps ?

Not quite. It is the certification required for selling products in China.
The standards are very similar to CE however, with just enough difference
to add some friction to trade.

It's very clear that many items on Ebay from China costing a couple of
quid (incl postage) and have a CE mark have never been near any
certification process.

True enough. However, the Chinese are very strict about certification
of products exported from Europe to China, hence the requirement for
CCC marking on such goods. In other words, you would not be allowed
to re-import many Chinese electronic products sold in Europe back into
China.

I have also seen Chinese power supplies sold by a reputable UK supplier
where the internal design changed substantially from one batch to the
next without any evidence of re-certification. There was no change in
part number.

One automotive USB charger I looked at had conducted emissions more than
20dB above the allowed limit. It had component footprints for filtering
capacitors on the pcb but they had not actually been fitted. This was
bought from a major UK supermarket. The first batch of samples might
well have been certified and then subsequent production "cost reduced".
The savings would have been one or two pence in a product sold for
around £10 at the time.
