In the long run, granny charging is better for the battery than fast charging (according to what I read). However, it’s rather inconvenient if you require a lot of charge each time, due to the speed.
If I had an EV, I would install a wall box. Since I’m only getting a PHEV, albeit 34 kWh, I will try using a granny charger only. I will still install the wall box as it comes free with the car.
Sorry, sorry, not free as it’s included in the price of the car already ????
