What is the charging rate (miles per hour) for a Model S60 being charged with a regular 110 volt outlet?

Four is very good, two or three is more typical. If you have a 20 amp dedicated 120, you might get six.

Accurate unless it is cold outside and some of the energy gets used to heat the pack. To get the most from a 110 20 amp circuit you need the 5-20 adaptor.

MikingCO, when charging on 120 do you hear the coolant pump running continuously? 4 hrs of charging at 120vac meets most of my daily needs, but I'm concerned about coolant pump wear. 4 x 7 = 28 hrs per week of pump run time. Anyone else concerned with coolant pump wear, while slown charging?

I used to get about 4 (I'm sure it was like 3.x rounded up). Never had the coolant pump run on while charging on a 120V circuit.

I have had zero, when the car was plugged in during very cold weather (below freezing temperatures) and had 5 mph with a strong circuit and comfortable outside temperatures. I view 120v as essentially covering passive losses. Anything better than that I feel quite good.

Isn't the limit 12 amps while charging on 120V ? In that case you would add 1.44 kw per hour minus about 12% heat loss . So 1.27 kw . If you average 3 miles per kWh , you get 3.8 miles . However , if you are only averaging 2.5 miles per kWh (400wh per mile) you get 3.17 miles .

The limit is 12A when plugged into a 15 amp circuit. With a 20A circuit and the UMC 5-20 adapter you can draw 16A.

Those are real miles, when the car charges it shows you the charge in rated miles which are independent of how you drive.

You can also convert a dedicated 5-15 outlet to 6-15, which is 240 V (15 A maximum). This would double the charging rate to about 8 miles / hour and I don't think you would need new wire, only a new outlet and a reconfigured circuit breaker. Link for the 6-15 Tesla adapter: Tesla — NEMA 6-15.

Incorrect. Charge rate in mph is dependent on consumption, if you look at miles of range. Model X P90D would charge the slowest out of the Tesla fleet, Model S 60 would charge the fastest.

I said of any Model S. The difference in consumption among the various Model S is not significant enough to materially change the charge rate. 120V 20A is 5 miles/hr plus or minus a fraction of a mile regardless of Model S. 240V 40A charging is 29 miles plus or minus a mile.
