Are there options that don't limit the output power? Typically the light power is limited, so dynamos only provide around 5 W or so, which already makes them not so attractive even for charging your phone on a bike.
I'm not totally sure about the specifics since despite being an engineer, I cannot distinguish electricity from witchcraft. That said, I do know that if you want to charge your phone from your dynohub you need to ideally have some sort of powerbank in the middle.
I think the problem with having a higher wattage is that you can't have a substantial amount without introducing what would generally be an undesirable amount of drag. It would certainly be useful to be able to engage / disengage a dynamo hub at a higher wattage though.
