I've got a 2009 Harley-Davidson Sportster 883 Iron and was wondernig if it was possible to mount a cellphone/mp3 player on the handlebars and power it. Is there a cigarette adapter thing that I could install or a USB powering solution?
Almost anything is possible. I've mounted a 12v power outlet (the cigar lighter thing) on my little Suzuki. Just hit the auto parts store, get the outlet, mount it where you want it and wire it up to a suitable hot, using a fuse of course.
