Yeah - you'll see that I mentioned that - if that is true, then great. But, IMO, it's worth verifying. Even more worth double checking if the building is old, or an extension cord is involved.
It's definitely true on a Tesla using their mobile charger. The car will report on its screen exactly what it's charging at. When I charged at 120v (before getting a hardwire charger installed), the car reported charging at 12 amps.
