Or, if we are getting fancy, 240V/20A, which can be run with just a single 12/2 Romex, provides around 3x the "range" per hour, since there is some fixed overhead losses to heat the battery pack, turn electronics on, etc.
In new-ish (but not new enough to have EV charger prewiring) construction, garages sometimes have a dedicated 20A receptacle circuit for a garage freezer. If its a dedicated circuit with one outlet, you can rewire the 120V/20A to 240V/20A to get 3.8kW vs 1.4kW on a 120V/15A. The cost to do this (to code) would be about $150, or $50 if you don't care about GFCI. Could also buy a used, cheap, hardwired EVSE rather than making it an outlet.
- neogodless 1y agoWhile it's not cost effective, I've been debating getting a $300 smart switcher that plugs into my dryer's 240V / 30A, and includes an adapter to the 50A plug my home charger users, while preventing charging while the dryer is in use. Dryer is next to garage, still need to make a "fancy" hole in the wall, but definitely like the idea of the faster, more efficient charging option. In the meantime, slow-ass 120V/15A charging is plenty for my needs.
