Quoting "miles per hour" for charging is problematic because it depends how far you personally can drive per kWh
Which is why they all give you the kWh or - after that its just the math and knowing what you are feeding your car.
Its the same for any EV.
110V @ 12A = 1200W (1.2KW)
220V @ 30A = 6600W (6.6KW)
etc etc
Leaf with claimed 24KW battery is about 4-5 hour to full from totally empty with a 6.6K charge - substantially longer on 110, hence "trickle" charge
