You don't have to go with a Tesla wall connector for your Tesla, you can use a third party home charger with the included Tesla adapter. I have a Chargepoint Flex at my previous house that I haven't set up yet. I bought it because you can configure the amperage based on connection (and unknown to me at the time there are ways to set its amperage via software as well) and my old wiring was, shall we say, "suspect". But if wired correctly it will go all the way to 50 amps, which is a pretty good rate for a home-based charger. Mine is currently set at 30 amps which gives me roughly 11-15 mph in my Lariat ER.
