The Blaze Dyno isn't too bad for around town with street lights. And it has a binky mode so you can irritate the Germans. I never had a dyno light that worked well on an unlit MUP until I upgraded to the Phillips SafeRide. If I was going cyclocamping and didn't have the cash for a good hub and USB charger, I'd just buy a Planet Bike 2W Blaze (runs from 2xAA) and carry a few extra batteries. Works on the bike and in the tent.
