So you end up with a lot of that power going to heating, not charging.
For a PHEV in a heated garage, I agree, a 20A outlet is totally fine. For a full BEV parked outside? Not gonna be great.

Yeah, there are a few factors. The wall charger is more efficient than the 240V plug overall, so that would help. But parking outside at -30 and trying to charge will likely not be great.
