Other than that, absolutely fantastic piece of equipment. AFAIK no contest in terms of watts you'll get out of your dynohub. May not be robust enough to tolerate frequent disassemblies. I've "pivoted" to the battery bank strategy and minimal energy consumption. But may well reinstall the Forumslader this summer-where-we-can't-ride-far-anyway.
I reckon the way to go is to upgrade the batteries to much bigger ones and have it portable so you can use it as a battery bank with the USB charger. I installed mine with some 18650 batteries into a piece of PVC pipe about the side of a bike pump and mount it on the down tube using SKS pump clips. I got some screw connectors from ebay for the input connection. So I can run it on the bike, then take it into the tent at night, plus charge it from an AC outlet as well as a replacement for a battery bank. At some stage I might upgrade to 26650 batteries for more capacity since I sometime run a phone and a wireless hotspot on tour.
