Charge speed on plaid with nema 5-20?

A 5-20 is a 120 volt 20 amp plug.

For charging you get 80% of 20 which is 16 amps. No car can go higher than that.
120 x 16 = 1,920 watts
Taking that one step farther, divide by 330 Wh/mile to get the miles of charging per hour. So 1920 W / 330 Wh/mile = 5.8 miles / hour

 
Yes I guess wondering if it’s possibly less on the plaid, like 5 instead of 6. I know the current pull is the same but the mile algorithm per calculation I’m talking.
So your real question is whether the Model 3 or the new Model S Plaid is the more efficient vehicle. Given the weight of a Model S Plaid is greater, overall larger vehicle size than the Model 3, I would expect the Model 3 is likely the more efficient.

The easiest way to get a quick comparison is to look at what is listed as the MPGe values on the respective vehicle fuel economy stickers. I do not know if those values are posted yet to the EPA website, if so you can look them up directly to compare.
