Just wanted to pass along a great product I found. I use my Iphone to listen to music while I ride and on long trips it tends to drain the battery. And since I also use to navigate a dead phone means I cant find my way home. I found this great power outlet that I just installed and it works great. Waterproof, easy to install, comes with handlebar mount (which I didnt use because I mounted it in the tail section) and its relatively cheap.
