My commute was 60 miles a day when I bought a used model S 2 years ago and ordered a wall charger at the same time. I have a supercharger 2 miles from my house and the car has FUSC, BUT it is SO convenient to pull in the garage, plug in wall connector, then have car ready to go in the morning. It took me a a couple of months before I finished the wall charger install. The few times I used the mobile connector at 120 volts seemed barely worth it. All night for 40 miles of range added. Driving over to the supercharger was not bad, for a short while, then got old real fast.
I am very happy with the wall charger (40 amp circuit). Did it myself as home breaker panel is right next to the car. Watch a few YouTube videos, $40 at Home Depot and a few hours later to be charging at home. Mobile connector stays in the car for trips.
