Yes I own one and ran out of power once. It was the day after I got the car and was not fully used to it. We used the car for errands most of the day and I ran out of juice less than a mile from my house. A neighbor was kind enough to let me charge up and I was on the way home soon after. We had bought the car and got home late the night before. It did not have much time to charge overnight and was charging at the slower rate of 110v. That was way back in March 2013, I have never ran out of juice again.
