A friend suggested that a generator hub might be a good upgrade for my bike but I'm going to need some convincing. I'm building a new whilst anyway for on/off-road touring, so now would be the time.

I don't intend to ride on tour during the night. I do see how it could be nice for USB charging my iPhone, camera, etc, while traveling but I can also use a battery pack for that... though the battery itself needs charging after 2-3 days, so switching to a generator would make me more independent for remote areas and guerrilla camping.

This bike does get ridden around town a lot during the non-frozen time of the year, with a different wheelset. I could see a generator and light being useful for that. But of course I'd need 2 generator hubs then.

Ready to be convinced if you can recommend it, but not feeling it at the moment. Thanks in advance for the input.
