I guess I’m doubly smart then… I got a wall connector for my Y and an outlet/TMC (not Home Depot brand… Bryant) for M3SR (because it can only charge at 32A anyhow, so TWC would truly be pointless), both installed as side jobs by a licensed electrician.Why is the "wall connector" better than a standard 220 volt outlet you can buy for less than $20??? OK, so it charges faster. Whoop-de-do! You plug your car in at night and it's full in the morning, same as the outlet. The main difference seems to be that you have to pay 50 times more for the "wall connector", which, of course, makes it better, right? And, as an extra benefit, you can ONLY use the wall connector for charging your car, while I can plug several different things into my outlet. Who are the ones making a profit from these? What's the push? "Ooooh, it's white, and I had to get an electrician to install it for an additional $500, so it must be better!" NOT.
I've been using the same 220 volt outlet to charge my cars for over ten years. I bought it at The Home Depot for about ten bucks and put it in myself, which is allowed in my county. If I sell my house, I just leave the outlet here for the next owner, so he can charge HIS Tesla. No one needs a "wall connector". Even rich Tesla owners are smart enough to spend their money wisely, and this ain't one of those deals.
