Another thing I'd like to add. I've got a ChargePoint card and the smartphone app. I have used public charging a few times. Just last Sunday I ran into a Walgreen's and plugged in while I was there. My total charge time was about six minutes. Whoo-hoo, that'll add some miles! Unless you're charging all day at work, or doing a shopping marathon at the mall, public charging stations don't help that much. I am glad to see them because I think they will help to change public perception. But from a practical standpoint, they're not as important as many people think.
