The only issues with that is 120v charging is less efficient, and if you are doing it outside in the winter it starts to really make a difference.

How can the charging losses be minimized? Higher-voltage charging equipment is one way. Our long-term 2019 Tesla Model 3 Long Range Dual Motor test car is currently averaging 95 percent efficiency from a Level 2 Tesla 240-volt wall connector. Staffers charging at home using a typical 120-volt wall outlet saw efficiency of, at best, 85 percent, and it dropped to as little as 60 percent in very cold weather, when charging the battery requires expending significant energy to keep it warm.
