Certainly in the UK, we don't have the same issues with terrible Chinese fakes that I hear about from US Amazon users.
Amazon UK these days is definitely full of Chinese reproductions and drop shipped knock offs.
Whether they're dangerous I don't know, I've not tried them.
I don’t know about fakes, but browsing Amazon DE feels like browsing AliExpress when looking for any technology products. Especially cables, adapters and such.
We don’t have the fakes problem but Amazon in the UK has a growing amount of stuff that is just resale of stuff from temu. I suspect if you tested the top 10 chargers on Amazon that weren’t anker, you’d find the same problems.
