Question for the more knowledgeable electricity people!

Yeah, just that this is a 1 time use And not sure I want to buy such a EVSE for a one time use or drag one around. If an adapter for 40$ could have worked, then that would have made my day and wouldn't be too big to cary around in those rare occasions I could potentially need one.

If you don't want to invest in an extra 16 or 24A 240V EVSE then you might need to just spend a little extra time charging as much as you can somewhere else before you arrive and then just trickle charge over 110V while you are there. In 5-10 years battery technology and infrastructure will improve to the point where this is a non-issue, but for now there are still going to be a little growing pains with EVs. Maybe someday nema 14-50 outlets will even be required for new home and/or business construction (or at least common practice if there is high enough demand from most people driving EVs).

Actually, here in Quebec, Canada it's now in the house building norm to install a 14-50 outlet in any new homes that are built, so yeah, for now that's what I'm going to do, charge at the nearest high-speed charger (about 50 miles away) and charge the rest at s 110 line at the cottage.

I guess none of us has experimented with that so you might as well be first.
I cannot tell if Ford's charger selects amps based on the plug or based on sensing the voltage. I know that when on 14-50 outlet it takes a minute to ramp up a current. It starts with very low current and goes to slightly below 30 amps. Would it stop before that if it sensed a voltage drop? Who knows. Would it draw above 15 amp from 110v regardless of the plug? Probably not.

Current and wire resistance is what produces heat in wires, not voltage. Therefore, I suspect most EVSEs will just simply deliver the lesser of the EVSE rated max current or the vehicle's requested current, regardless of actual voltage at the outlet. However, voltage could affect charge speed if the vehicle is requesting 100% of the EVSE's current as supply voltage would affect the actual watts being delivered the vehicles ac to DC inverter (and therefore the DC current it can deliver to the battery).
