When on a bike tour I use my dynohub to charge my powerbank, then use that to charge my NiMH AA and AAA batteries. Have not bought disposables for about 15 years.
The Superflash is on the left, the Superflash 65 is on the right. The dyno powered taillight on the fender is typically off when touring, as I am charging batteries instead.
