You will not need to charge every device every night. Not even every second night.
I'd suggest that a 23,000mAh battery should keep all your devices charged for about 4-5 days (or possibly a fair bit more) and in that time you may well land in a campground/cafe/B&B where you can mains charge it. Unless this battery is substantially different to the Powermonkey Extreme 9,000mAh battery you shall be able to charge it from your e-werk - just slowly. The Powermonkey Extreme gets about 1/3 charged after one full day riding (or one day in the sun with its solar panel), so the 23,000 would probably take about 6-8 days of riding to fully charge it.
The trailer set up is just for icing on the cake.
My bikes front dynamo hub caters to my needs of lights, Edge 800 and phone with no probs so far.
The trailer set up is purely for wants and not needs.
As you say its only occasional usage to keep my camera battery charged up via:

The Nikon battery takes lots of shots in between charges and the ability to recharge is purely a bonus.
Its unclear currently if I'll succeed topping up my macbook air via the 23000 battery but I'll persevere looking into it.
I may end up grabbing a iPad with keyboard which I know the 23000 can charge.
My questions for Daggo was about what voltage and amps to set the E-werk to as all that guff is another language to me and all I'm after is really a fit and forget solution.
I'm unlikely to worry about wind vanes or other methods of turning the trailer wheel.
It just seemed silly to have a spare Son28 and not utilise it when dragging a trailer around.
No one else has mentioned utilising the 23000 with a dynamo hub so I'm in the dark and breaking new ground.
We've gone from people saying it cant be done to now its looking possible.
I just wanted some setting to try whilst limiting the potential of frying pricy (for me) electrical equipment (Ewerk/battery).
I'll be happy keeping the 23000 topped up knowing it'll likely be some days riding from low charge.
