That's true, but now you need to spend the night.

A model 3 realistically gets 4~4.5 mi / kWh, US 16A@120V is rated for 1500W continuous, so that's about 6.5 miles per hour of charging. 20A@120V is close to 2000W continuous, so that's about 9 miles per hour.

Were blacksmiths open 24 hours?

You did not need to stay at the blacksmith’s for hours to get a can of gas which would carry you to the next supply location.

Unless they were closed of course. Then you’d be waiting hours or even days for them to reopen.

In that situation you might start knocking on doors.

If the comparison is to buying an emergency gallon from a "town blacksmith", then let's get those numbers too: a (Ford) Model T was said to get 13 to 21 miles per gallon. So if you managed to buy a full gallon from your hypothetical blacksmith in history, you'd need two to three hours on a boring wall plug to get the equivalent charge in your Model 3. That's quite a bit more time than you might want to spend in a small town, but that's "a lazy afternoon" amount of time (or a good four course meal with all the fixins depending on whereabouts in the country you find this stop and the hospitality of local restaurants) and still not "spend the night" amount of time.

I know this thread is entirely about comparing apples and oranges, but the historical examples weren't getting a full tank from a small local Blacksmith back then and so it doesn't make sense to worry about getting a full charge in this situation either.

Are you suggesting people steal electricity from private homes or businesses?

Are you suggesting blacksmiths weren’t compensated for providing solvent?

Are you suggesting that there exists a large nationwide network of chargers that is as convenient and as easily accessible as the electricity grid?

Yes they are called wall outlets. There’s even more of them now than there ever were blacksmiths.

There are zero wall outlets in the middle of the desert.

Same as the number of blacksmiths, then.
