It seems every new gadget has a proprietary battery so gone are the days of grabbing a bunch of AAs anywhere along your route. I've read on this forum the virtues of solar panels but I was wondering if anybody has ever heard of rigging up a dynamo hub to recharge electronics. Seems like you could unplug it from the lights and plug it into some converter for a suitable current for small electronics.

I just hate roughing it without my GPS, MP3, hair dryer, military grade Taser and smokeless ashtray.

Thanks everybody.
