I have mixed results when trying to charge my car. It's about electrical outlets.
Two prong receptacle without ground (even if used adapter) wouldn't work, and I understand it.
The same outlet with adapter and 3 prong extension simple power cord strip (that is full of other plugged appliances) work just fine.
Two prong receptacle with ground will not work.
AFCI receptacle works fine.
I know nothing about EVs, but what type of connection does the car have? Im just guessing, but it could be something built in to the cars charging system detects no ground and somehow the power strip "tricks" it into thinking the ground is there. Why it wont charge with a regular grounded outlet, maybe the ground wire isn't connected in the box?
The car has an original charger that was supplied by the maker. It seems to me that there is no problem with the charger, but with the outlets in my house. Just trying to figure out why some outlets work better than others.

I am confused...
What do you mean by a two prong receptacle with ground?
The two openings in the receptacle should be a hot and a neutral, where is the ground coming from?
Please hire a licensed electrician and please read your owners manual. It's possible that your home might be old enough to not have a ground, but only a hot and neutral line. Your receptacle and plugs might have 3 prongs, but if that ground "earth" line doesn't connect to anything, then the EVSE might not work. Which EV do you have and does the EVSE have any diagnostic lights. I know many made by ClipperCreek have LED diagnostic lights on them and can hint at what your problem is.
You need an outlet that can handle atleast 15A, if the outlet is too weak or old it won't charge at all. If some of your outlet can charge while some can't it means the circuit has too many devices on it. You need an outlet on a circuit that is not overly used to supply a stable charge. Every home should have multiple circuits. EV chargers will detect whether the circuit has a stable current. This is for standard 120v outlets. For level 2 you need a 240v/40amp circuit at home.
