0.14 ohm ESR, 0.3% Vloss. I suppose that ESR is OK considering the accuracy of the meter. At least they are "real".

I read that scam emails purposely misspell words to ward off those who are paying attention. Though I suppose it's more likely that they simply don't know or care

I have a bag full of various values of small capacitors from AliExpress. Almost every value is a different brand. I have Jwco, HuaHong, JNC, ChangX, JEC, JackCon, Chong, MHC, HongKai, Fujicon and United.
I see that Fujicon is especially well-known on this forum. I wonder how many of the others are marques of the same manufacturer(s).

I think with any component of questionable provenance/veracity it's a good idea to significantly de-rate it, if using it at all. Though I'd always prefer stuff from reputable sources.

Good point! Would be funny if the original power adapter used fakes/rejects though.
