You might consider installing a standard 12 volt cigarette style outlet, then you could get a USB insert or if you have items like an air pump for inflatables, you could plug that in to the outlet. I have 2 12 volt subpanels run directly from the battery, in at the back of the camper and one at the front and I would pull power from those. You could find a wire to tap in to, just have to be sure what else is on it.
