What is the difference between DC and AC power?
DC (direct current) power is drawn directly from the battery and will run several types of
RV appliances, like lights and water pumps. AC power (alternating current), is what is
used in your home. An inverter in your RV converts your DC battery power into AC for
AC-powered devices such as TVs, hair dryers or coffee makers.
