Power comes into your RV as alternating current (AC). To use anything kinds of appliances in your RV, you need direct current (DC). To make that happen, your RV comes with a converter. If you’re dry camping or boondocking and still intend to use power, you’ll want an inverter (which changes DC to AC).
The video above helps explain why these two devices are important and where to find them in your RV.
