I bought the 2018 Leaf last night. We're having typical December weather here in Minnesota: 20's (F) for highs and single digits for lows. It will get colder. My daily commute is 13 miles round trip. I've been advised by my local electric company that my detached, unheated garage's regular 120V outlet ought to handle the car's charging needs - at least until I see how I really use it. I have a friend in St. Paul who has used Trickle for the entire time she's owned her 2016 Leaf. I'd appreciate other folks' experience with this issue. I think I'm particularly worrying about the car sitting outside all day when it's really cold (windchill of -20's is common) in January and the battery isn't fully charged.
