It means you can’t make use of cheap overnight tariffs though. I get four hours of electricity at 7.5p per kWh. That 4 hours is more than enough to fill up when I need it. If I had to use the granny charger I would exceed the 4 hours and end up paying 39.25p per kWh. That would quickly eat into any savings from not having a wall box.Lucky enough to have a small garage to park inside.
My SE is parked at home for at least 15 hours per day plus I very rarely drive over 90 miles in that day.
This means the 3 pin granny charger is perfectly fine.
The £700 saving on a wall box pays for a few years of overnight slow charging once or twice a week.
