This should allow me to charge when I want/need to and shut the generator off entirely when I don't. I can swap it to another bike easily if I'd like to use a different bike on a trip. If I want to add a light into the system later I can. Its also slightly less expensive then a generator hub and a lamp that also charges USB devices.
Looks totally cool! The 90 grams for a mounted unit is really great. Would love to hear a real-touring-world report on how it performs.
My back-of-napkin calculations:
- device rated 6v, 1.5 watts at 15 kph
- charge smart phone = 10 watt hours
- 7 hours of riding should do it
- reality???
