I agree. We live in Phoenix, and the car makes plenty of noise charging in the garage on a hot summer night at 40 amps. Our ChargePoint Flex will do 48 amps (its on a 60 amp circuit) but we found 40 amps works just fine.The Ford Mobile charger is 32 amp and not adjustable.

Reality is theres a few things going against you for a wall mounted charger at this time. There's an issue with the charge port, it's causing EVSE's to derate to sub 40amps. This currently isn't getting fixed.
There's also a matter of heat and waste. The higher charge you run into the car the more heat (read: fans running in the summer in your garage turning it into a sauna) and wasted electricity because of the heat, the fans, pumps and EVSE efficiency go down. Charging around 32 amps usually keeps the fans off or mostly off. This saves you a few pennies a day in power costs, and possibly more if your sauna heats up the house, which triggers your AC to run more.
Get an adjustable on the fly charger (the Emporia was just on sale for $300). I bump mine down in the summer, and probably raise it in the winter if I need to ram some power in for a trip somewhere on a couple hours notice. I thought my Tesla WallConnector was adjustable on the fly but it's not, so it's in a box for some new owner to take off my hands. I have a thread on On the Fly adjustable chargers here.
