RV Inverters: A Boondocking Necessity

If your idea of camping and enjoying the great outdoors is going off the grid and forgoing the conveniences of a campground, then you'll have to consider how you're going to power your much-loved and much-used RV appliances and hand-held devices. Sure, most of them have batteries, but they won't last for long. If you're planning to park your rig in an off-the-beaten-path location and enjoy uninterrupted tranquility, you'll want to invest in an inverter that changes DC power to AC power so you can use your microwave, TV, laptop, cellphone, and other things for extended periods of time while not connected to shore power. Let's take a look at RV inverters—a boondocking necessity—to help you determine which type and size is right for your RVing needs.

Inverter Types

There are two types of inverters: true/pure sine wave inverters (PSW) and modified/quasi sine wave inverters (MSW). PSWs use toroidal transformers (donut-shaped) and electronic circuits to transform direct current into a smoothly varying alternating current, one that resembles the genuine sine wave normally supplied to our homes. These are great for charging TVs, computers, gaming consoles, and stereo systems. MSWs, often less expensive but more efficient, use cheaper electronics like thyristors and diodes to produce a more rounded-off square wave that doesn't resemble a sine wave quite as much. These can power large electronics, like a microwave, but they can damage smaller, more fragile electronics or devices, like a laptop or TV, that includes an electronic or microprocessor controller. Also, since they send more power to the appliance than a PSW does, you run the risk of overheating when using an MSW.

Inverter Sizes

Just like RVs, inverters come in all different sizes. You can purchase small, portable ones that plug right into your car or RV's cigarette lighter, or you can purchase a large one that you install inside your RV. The size that is right for you depends on what type of camping you do and what appliances you'll want to charge with it. If your style of camping is more weekend warrior than full-time RVer, you might be just fine using small, portable inverters. As a weekend warrior, you're not going to be working on your laptop for 8 hours or watching a whole season of your favorite show on DVD. You're most likely going to be exploring the beauty around you and enjoying the flickering lights from your campfire, not from your RV. But when you do want to watch TV, charge your camera or cell phone, or use your laptop, simply plug in a portable inverter to your car or RV cigarette lighter, plug your appliance into the inverter, and turn it on.
