Outlets will ONLY work with shore power or generator power.
Most RVs don't have inverters but all have CONverters.
You would have to wire an inverter into all the outlets.
A simpler solution would be to wire an inverter to the batteries.
I hard wired a 400w inverter to my dual batteries. It has two outlets and USB ports.
I use it for tv/dvd and recharging electronic devices.
But you need at least two deep cycle batteries.
