![]() You’ll need to be familiar with your RV’s electrical system, and the number of amperes your 12-volt DC appliances (or at least the ones you’re realistically planning on using all at the same time) put out. That generally means that larger RVs, in which more appliances like lights, phones, and laptops are plugged in at any given time, require larger RV power converters. ![]() So, to look at the very basics, RVs that use more 12-volt DC appliances at the same time will need larger RV power converters to facilitate the use of all these appliances. We’ll tackle the basics first, but if you’re gearing up to buy a power converter for your RV, you will have to do some math to figure it out. What size power converter will you need to make your life on the road as comfortable as possible? There is a technical answer to that question, and a lay person’s answer. Check the current draw on each device in your RV for a more accurate calculation.Īppliances powered by 120-volt alternating current - and which therefore don’t rely on an RV power converter - include AC units, fridges, freezers, and microwave ovens. Refrigerator – on 12 volt mode: 35.0 DC Amps.Digital Satellite Receiver: 2.0 DC Amps.Fluorescent light, double, 30 W: 2 DC Amps.There’s a whole load of RV appliances that rely on 12-volt DC power, some of the key ones include: TV antennas, laptops, radios, CD players, and similar small appliances.Any ceiling or other fans (though not air conditioner units, which run on 120-volt AC power).What is an RV power converter used for? All 12-volt DC (direct current) appliances need one to run efficiently, without draining your RV battery - and some of the most important appliances in your RV run on 12-volt DC power, include: ![]() That’s exactly why newer RVs come equipped with a power converter by default - but if you have an older RV and the power converter is not sufficiently large for your needs, or you believe that the RV power converter is faulty and needs replacing, you may be shopping for a new one. Every RV needs an RV power converter, without exception. ![]()
