Since these USB battery banks are not that heavy, I opt to size mine so that I can go multiple days on it. But yes, you eventually have to charge the battery somehow. Dynamo hubs are tempting, but my understanding is that they won't really run your lights AND charge your battery and/or your electronic devices at the same time. A dynamo hub might run your lights and keep up with your phone in Airplane and Power Save mode, but it won’t manage lights and a cell phone navigating with GPS, etc. But if you are willing to give up daylight running lights and moderate the power consumption of your other toys, a dynamo hub is tempting.
I still prefer multiple battery lights because of the redundancy. If you go “dynamo only”, a failure of the wiring or the hub could leave you in the dark. Same goes for a single battery light, of course. But with multiple battery lights you have a high degree of redundancy. Dynamo with battery light backup is good, but not much of a weight savings (if any) and you can’t use multiple bikes easily.
