For example, will it run at 110V 16A if plugged into 20A circuit? WIll it drop down to 12A if connected to 15A circuit? Can it detect circuit amperage? Or is all 110v charging stuck at one voltage like the OEM EVSE?
Looks like both are 12a@120v and maximum amps at 240v, that is maximum of your vehicle or EVSE, it has no idea the amperage of your circuit so in the case of the 40a EVSE if your vehicle can draw 40a you better be plugging it into a 50a circuit.
Note, I believe OP has flown the coupe but it looks like the price of the 40a model has dropped $80 and is currently $350, which for a 40a EVSE is quite low and the 16a has dropped to $219($40 drop) which IMO is more in line with similar 16a EVSEs. Note every other dual voltage16a EVSEs I've seen run the same current at 120v as 240v, that is 16a which if your vehicle can charge 16a @120v means you'd need a 20a 120v circuit, if you only have a 15a 120v circuit then these EVSEs may be the way to go. Personally, I prefer an adjustable EVSE where I can set my own amperage, both on 120v and 240v, but those tend to cost more than either of these EVSEs.
