Public chargers usually have very low power (e.g. 11kW), are as of now not common enough and typically limit the parking time to a few hours (that are not even sufficient to fully charge), requiring one to go back again and find another parking space after that (which, later in the evening/night, is even harder).

In addition, in many countries and charger networks, there’s often a surcharge past 5th hour or so plugging in, charged by the minute, resulting in a prohibitive cost overnight. So 11kW peak power times 5 hours times efficiency of .8-.9 gives you like a half of a recent Tesla Model 3 or Y battery capacity.

A few hours at 10kW recharge several days typical use.
