My ultimate goal would be install dynamo USB charger to charge USB power bank to turn on lights and cell phones, etc.
there have been a few articles/papers written about the drag of various hub dynamos, both with and without the light turned on. There usually is more drag with the light on, but it's usually just a few watts, and most people don't notice it (myself included).
