I use this
usb adapter
hard wired directly to bike, mounted on my fairing stay. as for the phone mount, I went with a cheap iPhone holder from 5 below, just zip tied it to my triple. it works great, misses the fairing, I have a waterproof case on the phone so don't have to worry about that. and it made it on a 6k mile trip across the country without breaking or anything. all together for under 20 bucks
