Probably the highest output device so far is the Forumslader, from Germany, it has a lot of trickery so it can maximise the efficiency of the hub at low speeds like you'd find touring, but it's not cheap!
Cycle2charge also claims high output. Price is not bad. I do not have one, only looked at web info.
