The Busch and Muller Toplight rear lights are good. I've got two of them, although they're 6+ years old so I'm not sure which I've got or what the nearest current model is. Check out https://www.xxcycle.com/dynamo-rear-light,en.php for some examples.

Most of my tours are done in the day, so I haven't needed a dyno setup for touring. Perhaps someone else can give you some recommendations for charging phones and GPS.
