If you run an RV when traveling, you will need an inverter to translate DC current into the AC that most appliances use. That is why Camping World stocks a line of inverters of various sizes that are meant for the road. Your best choice, especially if you want to be able to power all of your electrical toys, is a multi port unit.
You have a choice between inverters that can handle 600W to those designed to handle 2800W. With pure sine wave technology you get clean, reliable power with little distortion. Many of these units come with a 12 or 24-volt configuration, making them ideal for any size source.
