Shore Power
Shore power is an external electrical connection that supplies electricity to an RV at a campsite or storage location. It allows the RV to run appliances and charge batteries without using a generator.
Generator
A generator produces electricity for an RV when shore power is not available. It can power appliances, air conditioners, and battery charging systems while camping off-grid.
Inverter
An inverter converts 12-volt DC battery power into 120-volt AC household electricity inside an RV. It is especially useful for off-grid camping and running standard appliances without shore power.
