When I head out on an off-the grid tour, I go with my kLite system, my dynamo wheelset, and two Voltaic units - one charged up and stored safely at the bottom of my frame bag and one that's charging from my kLite USB charger and front wheel hub dynamo in my top tube bag. This belt and suspenders battery - dynamo approach allows me to go all-in on electronic navigation and alleviates range anxiety. With this setup, my limiting factor is now entirely related to my fitness.
