I have a new Surly Long Haul Trucker and am busy customising it. I'm keen to add a dynamo hub to power a front light and perhaps charge a mobile/cell phone. I know very little about Dynamo hubs, but have googled and the above combo seems to get good reviews.

I will be getting a Dinotte rear light (Dinotte Quad) .... I'm not sure how a Dynamo would charge that during the day, as it micro USB Charging system

Is there any better combo?
