Thinking about my order. I don't need rapid charging in the evening and can't really anticipate when I would. However, I want to look to the future as I consider what to put in my garage. It is a detached garage, so I will have to pull wire. I am deciding between 1 14-50 plug with 50 amps, 2 with 100 amp service (in case, at some point we have 2 electrics), or an HPWC. The HPWC will cost extra in the car and - I think - extra to install. I am wondering also whether the dual chargers will eventually allow more rapid charging on the road. Haven't seen anything yet, but in the future? BTW, I am in the Northeast. Any advice?
