I have found the E-Werk interesting - here's a review of that:

The reviewer was using it with a sidewall dynamo, but it would work equally well, I think, with one of the hub dynamos. I find this very interesting, since in the past discussions about charging your gadgets from a dynamo have always seemed to end up with people talking about DIY solutions that involve wiring and learning about voltages and diodes (or whatever) which I have absolutely zero interest in spending time on. So something like the E-Werk, which sounds like a ready-made package that makes the world of charging from a dynamo much more "plug-and-play", is very attractive to someone like me.
You might reconsider looking at the dynamo hubs - from what I've heard, they really are very good. Never used one myself, but charging gadgets is such a hassle on tour that I may well try it out at some point.

The E-WERK, needs a "buffer battery" so with the hub or dynamo it works out to be quite expensive. It's nice that you're self contained, but you can pick up a 1st generation Hypermac mini for $50 and it'll charge your iPhone 6 times. As I tend to duck into a Motel about once a week it seems like the most convenient solution for my style of touring.
My lights run off AAA batteries which are easy to buy and I carry a spare set. My best bit of electronics is a small Sony radio which will run continuously for a week on a single AAA battery and provides lots of entertainment.
