Just wanted to add my experience.........
I've had my 2018 leaf for a month now. Originally, I was just going to stick with the 120V Level 1 option. However, being that 240V Level 2 seems to be at least 4 times faster, I decided on that option.
It's awesome that Nissan provides a charging solution that negates the requirement for a charging station. (Providing that you have the model and/or options that include the cable!!!)
I am lucky that:
1. I have a newer home with a 200 amp panel
2. The panel is located outside, on the garage wall!
So, the electrician installed the 14-50 receptacle in the garage wall, and ran around 1 foot of the thickest cable I've ever seen, to the breaker box. There, he installed a 50 amp breaker.
Haven't received the bill yet, but the quote was a maximum of $225. I've used him before, so I think it's actually going to be a little bit cheaper.
I think that for $200, the convenience of the L2 charging is well worth it.
Looking forward to seeing pics of the new LEAF!
