Don't be an ass, start with contacting the seller.

Sure. In fact, the seller does not have any culprit, hundred of shops are selling this. Now the product is imported, only way to get rid of it would be confiscating it (that happens once every now and then, when police makes checks).
But I would be interested to just rectify for the next time who is responsible, i.e. the importer (which is one), which states its CE credential on the product. Because it has proper CE marking, hence is the DoC are false - if such design is not CE compatible. Maybe it is, I am not a legal expert.

You mentioned earlier to warn the importer, but isn't it already aware is doing things in a shady way? Btw, here the importer is not the seller.

I mean, I have nothing wrong by using this product, the problem is when someone not aware uses that. One thing are bad products which I am looking for (looking for cheap stuff to experiment or whatever), another is when someone get that and is sold as a safe device (CE labels etc). This should be limited, in my opinion. Going to the seller will make him/her give the money back, but not stop selling the entire batch because a random guy says its not safe in its totally personal opinion. You know what I mean? I know, I don't want to be an ass, I just trying to understand what would be, at least theoretically, the right thing to do.

I do think the importer is legally responsible here.

My totally personal opinion is, that this is not safe product.

You don't need to reverse engineer this piece of total garbage. Just looking at distance between one of mains tracks and "positive" output that looks like negative terminal makes it very obvious that this "charger" is dangerous.  CE mark means nothing, or as some may say it means China Export.

If you want a cheap torch, don't buy ones with charging port, rather buy one where you need to take out cell to charge it. Buy on AliExpress/Ebay single cell battery charger (something like Liitokala li-100 or similar, there are cheaper ones, but dodgy as heck) and use it with proper usb Charger.

If you are in travel and need flashlight you could get ones that run on three AAA's at least it's safer.
