And you can charge a lot in 12 hours at 120v. A tesla can add 3-4 miles of range per hour of charging, so overnight, you get 3.5*12 = 42 miles added. Teslas can charge at higher power, but it's often not necessary. Other cars, like the leaf can charge similar or slightly larger range at that amount of power because they are generally lighter. 120v outlet and daily range use of less than 40 miles and you are set. In the winter, if you run a heater, you will of course use more power (gas cars get almost free heat because they are ICE). So you need a spot to charge, at least a 120v outlet. The next limitation is quick recharge. If I want to drive somewhere at the range of my car (say 80 miles with a leaf or i3, or 250 miles with a model s), and then I want to do my business, quickly recharge and go back home right away, you need a faster recharge, like an hour. Chademo can do this for leafs, supercharger handles that for teslas but they are rarer. Tesla can use chademo with an extra cost adapter, but they can also use high power ac (80 amps 220v) and charge 60+ miles of range added per charging hour.
