Cheers, I'll have a read of that. I don't plan on stopping, certainly not for any length of time that would let me charge stuff. Where'd you hear about the Revos with USB? Could I create a similar setup using the dyno to either directly charge the Six Pack or the Garmin(s)?
hippy-
Revo USB stuff from people with contacts... I'll see next week if they have any news...
Dynamo > Sinewave Revolution/Cinq Plug/other regulator > cache battery or Garmin will work, I assume it would charge the sixpack too, I'll see if I can test with my Toro at some point.
Wonder if @gabes might be able to offer some dyno/charging electronics advice?

Rob Dean's thought's on the subject...
2) Isn't a dynamo draggy? Well, Please excuse the maths, but if you rode at 20mph for an hour the light would pull about 6W from your legs during this time, this is equivalent to approximately 5.2kcal. There are approximately 72kcal in a McVites Digestive biscuit, enough to power your light for just under 14hrs and that's assuming you pedal down the hills and around every corner! So yes, it does draw a tiny bit of power, but I certainly can't tell the difference and it's a damn good excuse to eat an extra biscuit every few rides ;-)
I use my Revo on and off road, couldn't be happier! Plug-in RedEye rear light is awesome too, no pissing around with batteries. Believe there may be some sneaky prototype Revos with USB-out knocking around, would simplify the charging side of things, at the moment you'd need some other device connected/wired in - Sinewave Revolution, Cinq Plug etc.
Saying that, Mike Hall did TransAm with a 6pack and Joystick as cache-battery, depends how long you're planning on stopping/if you get chance to top up power along the way...
