General Discussion / Charging iphone for maps while touring
« on: March 25, 2015, 03:00:01 pm »I am getting ready for a 3 week bike trip. I have hard maps but I think I would like to have access to my phone for directions everyone once in a while. I do not know how often I will have access to an outlet so I want to know how people here power their GPS/iphone/phone on long rides.
Should I invest in a dynamo, solar or just some spare battery packs?
Thanks!
