The answer to this is probably obvious to most. My 7kw home charger is finally due to be installed next week. I have been using a mix of granny and public faster chargers in the interim. In terms of cost of electricity, to get the same level of charge, is there any difference cost wise between using the 3kw granny and the 7kw charger, assuming the charge is stopped in both instances when the same, required level of charge is achieved. Thanks
