High voltage

High voltage in the context of RVs refers to the type of electrical power that’s similar to what you’d find in a regular house. This is AC (alternating current) power at the standard voltage and frequency for your country. It’s used for running larger or more power-intensive appliances and devices in your RV, like air conditioners, televisions, stereo systems, microwave ovens, electric fridges, space heaters, and water heaters.

This high voltage power also supplies the AC outlets in the RV. That means you can use everyday electrical devices like toasters, hair dryers, computers, printers, and more, just like you would at home. You can get this high voltage power from different sources when you’re in an RV – from plugging into a shore power outlet at a campground, from the RV’s generator, or from a power inverter that converts the RV’s battery power into AC power.

In the RV world, when we talk about AC power, we’re usually referring to this kind of high voltage power, even though AC technically just means that the electricity’s polarity reverses direction many times per second.
