I find that happens on occasion too. I believe that what is happening is that the device that I am charging is pulling power out of the cache battery faster than the hub can replenish it. So, when this happens I just stop charging whatever I am charging or a while, say maybe a half hour to give it some time to replenish the cache battery and then start charging things again. I use it for bike touring, so I am trying to be self sufficient without having to plug into an outlet.

Ideally all the bikes would have their own lights, but it'd be good if the charger were easily swapped between bikes. I wouldn't want to move my Luxos U between bikes "just in case." I'd only do it if I knew I was going to be using it on the other bike.
I have been accumulating lights/chargers at the same rate that I have been accumulating wheels with dynohubs.
But I have five different forks that I will put a dynohub wheel on, so I have zip tied wires with a Shimano type connector on each of five forks. (SP and Shimano dynohubs use the same connector.) And then I have some quick connect type connectors at the fork crown, so I can easily plug and unplug things. This way I can move a dynohyub from one fork to another fork on a different bike.
I also do not use wired taillights, all my taillights are battery powered. That greatly simplifies my wiring.
First photo, the quick connectors between the yellow wires and black wires make it easy to switch components at that point.
Second photo, the wires at the other end of the fork (on a different bike) plugged into an SP hub. If this second photo looks confusing, I have a Tubus Tara low rider front rack bolted to the fork, plus fenders, and a bolt on type skewer instead of quick release.
