We made it work for several months with our EV and a Level 1 charger cable ran out the back door before I could get the time to install the level 2 charger. For regular commuting around town, the wall plug would keep up. For longer trips, we would have had problems and had to have sought out level 3 chargers until we got the level 2 install finished. Level 2 charging at home was a game and cured range anxiety for us.
