So with the fact the Fusion only charges 3.8kw (see below) The car will only accept 16a (3.8 Kw) charging (I am told) but you can safely use the larger 30a (7.7 Kw chargers) you just will not get a quicker charge. Does it just make sense for the future to get the 7.7kw charger or is it just a waste of money?
