...dynamo hubs make increasibg sense the longer you are off the grid. But even then, the power generated over a day's riding isn't enough to fully charge a cellphone with a 4,000mAH battery, much less a cellphone plus GoPro camera, lights, etc. Is the higher cost, increased wiring complexity, and mechanical drag justified?

It is really nice to not have to worry about searching out where the outlets are in a restaurant and hope that a seat near one is unoccupied if you stop for lunch on a tour. I did a two week tour a year ago, first tour where I was self sufficient and did not have to worry about searching for power everywhere.
