even if every home plugged in one or two on 110-120 volt lines, it would be too much.
those transformers need down time
plus they are not designed for all homes to be putting such a heavy constant load on them
which is why you fridge or a/c in all homes is ok, because they switch on and off, and only have surge demads on startup, then taper down
these chargers charge constantly high for multiple hours, no breaks or rampdowns
