I've had no issues with the several "no name, Chinese" EVSEs I've purchased off Amazon and even directly from China, although I've never ordered off Alibaba, I ordered directly from the Chinese mfg, Zencar in my case.
Zencar is possibly the top of the line "Cheap Chinese EVSE mfg" but as they were getting a bit expensive for my tastes, I ordered an even cheaper EVSE off Amazon for my last purchase
I ended up ordering an "Anbull" Level 1-2 adjustable EVSE 16a off Amazon. The price was a crazy cheap $114.99 (currently $145 due to Amazon's Yo-Yo pricing) and I couldn't be happier. Nice cords, nice options, great price. Note as it will max out at 16a and has no "dummy proofing" if you set it to 16a and plug it into a 15a circuit, well you're probably going to see smoke
but that's not the fault of the EVSE, IMO it's an "operator error" but people are always looking to place blame and the mirror is the last place they want to look.
Look, I'm not saying one can't buy crap and possibly unsafe products off Amazon, and to a greater degree eBay and an even greater degree off something like Alibaba or even worse but one just needs to do their due diligence. Looking for my latest EVSE I saw even cheaper EVSEs on Alibaba but they just didn't seem Kosher to me, I'm glad we live in a country where we can mostly purchase what we want(ya I'm talking about "chicken tax"!!) not that I think someone should be able to sell something that is obviously unsafe and dangerous but hey, I've been using no-name EVSEs since '14 and using a little common sense, haven't gotten a shock nor blown up my car
Read reviews but take some with a grain of salt, I seriously believe sellers are starting(and probably have for some time) put out fake reviews, good and bad, which I don't like but again try and gain a consensus and try and sus out ones that are overly positive or negative. It's one reason I like to post my experiences on EVSEs here on MNL, I have nothing to gain if someone purchases something I've given a good review on or the opposite on a negative review, of course with everything YMMV
I have no personal experience with the Mustart EVSE quoted but just looking at I'd probably go with something different.
