Hi Chub ?
I picked up my 3rd electric car yesterday, for most of the time I’ve had the wall box and BP just changed mines last December 2nd from a type 1 to a type 2 in preparation for my new car.
Firstly I’d like to say they were excellent and absolutely no complaints about them or their service ????
I would say you don’t need the wall box, a properly fitted external 3 pin socket will charge your car fine ? ignore the doomsday merchants who’ll tell you it’ll take days and days to charge…. it won’t because you’ll almost never be topping up from zero, even if it was to take 12 hours, most people are home at night and sleeping during this time so unless you’re an extremely busy hyperactive person it’ll be fine (if you are an extremely busy hyperactive person I’d say get a wall box or an ICE ?♂️) I certainly wouldn’t pay a lot of money for something I’m unlikely to get much benefit from.
However a granny charger (a 3 pin plug one) is imperative, not only for you at home but if your ever away visiting people it is very handy so I’d insist on one or order a different car that’ll supply one ?
