First thing is how old is this leaf?
Does it have type 1 or type 2 connector as this will determine which type of tethered charger you can go for or if untethered it makes no odds. As all are type 2 to type 1/2 other end of leas.
If he's happy with the granny charger, then fit a 13A switch socket, suitable for outside use, near where the car is parked. Needs to be the type of socket that maintains its IP rating when a plug and lead is plugged in.
What happened in the end mate? Has he still got it I wonder?My Dad is picking up a Nissan Leaf. He is planning to charge it using the granny charger as we have a socket in the porch. Can anyone recommend a decent fast charger and what would I need to install one?
