ok, i'm about to undertake my longest adventure yet, to bike from the Arctic in Sweden to Africa.
one area of concern is how am i going to keep all of my electronic gear fully charged and ready to use?
solar power is great but why not harness the pedal power, after all, your on the bike all day right?
i've heard of dynamo's but have only seen them used for lights, not really for hooking up to a battery (to charge) or to a mobile phone, laptop, camera etc.
does such a device exist?
what do you do for power when your out touring?
all advice is welcome and appreciated, thanks
