Got a used leaf a couple months ago and love it. Now interested in buying another 2011 with 22,000 miles and 11 bars. BUT it only has the single charging port. My question is can I charge this car with a level 2 evse at home? And is it possible to upgrade to add the quick charge port? It's a great car otherwise. But if you get stuck somewhere and need a quick charge you're out of luck, right?
