secondly, the CE mark is only awarded and tested at the start of a product marketing cycle.
After that there is a chance that products get retested. But that's very rarely indeed.
As a hamradio operator we see enough effects of this so-called conformity in light dimmers missing filtering capacitors (yes they were there when the product got so-call CE-certified) because a couple of components less makes manufacturing cheaper.
I've even had a battery pack for my i-devices (IIRC it was the Gum Max 10,400 Mah one) that when charging blurred out so much radio frequency interference that practically all radio signals coming into my house were drowned out (FM broadcast as well as e.g. civil airband frequencies).
And yes it was CE-marked and sold in Europe and I tested two versions of it before advising Apple to stop selling it and returning the 2nd one for a refund.
Similar issues can be found with power line communication (PLC) adapters, plasma tvs etc.
So maybe that powerbar was nicely CE certified and fully correct and afterwards some components were yanked to make them cheaper. ON more then a million units that's making a lot of difference in the costs.
Although this time that trick failed (if true of course).
