Almost all RVs come with a power cord to plug into the electrical pedestal at a campground (developed campgrounds with available hookups, anyway). This is also known as a “shore power” connection. These power cords come in two amperages: 30-amp and 50-amp. A 30-amp cord has three prongs, and a 50-amp has four.
How is a camper powered?
RVs use both AC, alternating current, and DC, direct current, to power the components of your electrical system. The 12-volt DC system runs the electrical components of the engine and battery of your ride while the 120-volt AC system runs all the typical appliances and power outlets found on most RVs.
Will a travel trailer work without a battery?
Without a battery, towing your trailer safely (and legally!) is virtually impossible. But even if your travel trailer is permanently parked, youll need a battery to convert the shore power that youre plugged into to the correct current for your appliances to utilize.
