a word of caution on charging devices from a 12V cigarette lighter outlet. My experience is with the 14/16 ga wiring and usually pretty long runs in trailers the outlets are good for charging cell phones, etc. Where you can run into trouble is trying to charge a laptop or sometimes run a CPAP. My laptop charger draws 10A on 12V, enough that the voltage drop is enough to turn off the charger. CPAP with humidifier can be the same issue on 12V. So, if these give you trouble, best thing to do is run a dedicated short 12V run to an outlet with some #12 wire.
