I know that the Chieftan and RoadMaster have cigarette lighters for power ports. However, the Classic and Vintage do not. So, I was checking out my bike the other day trying to decide what I was going to do for power for charging my phone, when I found a Battery Tender style connector hidden in the forks. So, I ordered a Battery Tender thingy that converts to a USB connector. I've attached some pictures here.
