I thought it's supposed to take 7 hours on a regular home outlet @ 120v? Why is mine only taking 5 hours? I plug in when I get home but tell it to charge at 11PM when rates drop. I then get an email saying its done at 4AM. This makes it harder for me to decide on Level 2 charging at home, when I can get 12 miles or so in 2.5 hours. Anyone else seeing this? Was the 7 hours a conservative time specified by Ford? BTW, I am not complaining :)
