The plug on your RV is a large three-prong, heavy duty 30 Amp, 120-volt plug. If you go to a campground that has a regular house type outlet there are adapters that you can use to go from your RV plug to the house type outlet. When you do this you are plugging into a 15 Amp or 20 Amp power source.

Do RV outlets work on battery power?
