In my limited experience (several days of RAGBRAI and other social tours), the Luxos U's USB charging was enough to slowly trickle charge my iPhone while it was running Strava (a charge-intensive app, because it uses the GPS sensor) and sometimes streaming music via bluetooth to a speaker.
For example, in 6 hours of day riding (while running Strava), the iPhone's power would raise from 30% to 70%, or thereabouts. I presume the iPhone would charge more quickly if it wasn't running apps (especially if you put it in Low Power mode). During the night with the light on standard beam (the Luxos U has a +10 lux high-beam setting), there wasn't enough spare power to charge the iPhone while it was running. When the iPhone was powered off, it would gain a very slow trickle charge with the light on. The Luxos U seems to prioritize the light output over the USB; the light didn't appreciably dim when a device was plugged in. The Sinewave and other separate solutions may be more reliable device-chargers (but more expensive). *One oddity to report*: the Luxos U on my Riv Road 650b NEVER TURNS OFF. Normally, the Luxos U will drop its light output down to a safety/standlight intensity once you stop, and then the safety/standlight turns off within a minute or two. My Riv's Luxos (wired to a Shimano DH-3N80 hub) stays in the safety/standlight mode FOR WEEKS AT A TIME (tested this winter, during fat bike season). I have another Luxos U that has been wired to a Shimano XT DH-T780 hub and now an SP PD-8, and it exhibits normal behavior (turns off after a couple minutes). I'm not trying to fix this "problem" because it doesn't seem to have any ill effect (except maybe burning out the LEDs more quickly; but I think they have million-hour lifespans anyway). But it is an oddity! Drew, since you want to charge a lot of devices, have you considered a double dynamo solution? A front hub for your light, and a Velogical rim dynamo on the rear for USB charging? Riv/BOB listers have done crazier things...
