I have yet to use a supercharger but I am itching to go on a trip that uses them. I wonder how often people have come to a supercharger and found it to be down or not working. With a gasoline car I would never have any worries about finding another gas station if one was closed, but if I was planning a trip and needed a 30 minute supercharge I would be really upset if it turned into 24 hours on a 115v outlet. Has anyone come to a supercharger and been unable to charge? What did you do?
