> I assume this is a few hours or overnight. Even slow charging from a regular outlet gives enough over night or a 6 hour stay.

Not even close. We don't have a fast charger at home, so just charging from regular outlet. We charge from midnight to 3pm, or 15 hours a day (these are the cheaper hours with PG&E, although still a ripoff).

That's not enough to charge fully in a day. Fortunately my partner only goes to work every other day, so it's ok. If we needed the car every day, it wouldn't work.
