A couple of years ago the Aussie dollar rose to great heights.
I was able to purchase a Son28/E-werk with cache battery for both my bicycle and single wheel trailer.
The bicycle also sports a single Edelux and Philips Lumiring (tail-light)
I've been extremely happy with both the setups which have proved to be fit and forget.
It was the 5 year warranties on the Son hubs which made the purchase decision for me as at the time the Shimano had a one year warranty and was half the price.
SP wasn't around back then and the Sram and Sturmey Archer units were unproven.
The currency at the time made overseas purchases such a good deal I was also able to afford Sapim Cx-Ray spokes for all my wheels as well as a Rohloff rear hub.
The Aussie dollar had since tanked and I doubt I could now afford to repeat the experiment now.
Certainly no buyers remorse as I love the utility of my lights and charging system.

Any dynohub would be great and a worthy investment, even a vintage Sturmey Archer GH-6 which was my first dynohub for many years.
Supposedly only 1.8w but mine fired up my Edelux until I could afford to get my wheels built. The vintage GH-6 likely wouldn't charge your phone and weighs from memory 1.1kg for the hub alone but still way better than no dynohub at all.
