RV Surge Protectors: What They Are & Why They Are So Important

RV Surge Protectors What They Are & Why They Are So Important

It’s no secret that having an RV is a big investment. Whether you purchase one that comes with all the necessary amenities or you build your own custom version, you’ll want to do everything you can to keep your RV safe. And one of the easiest ways to do that is to have an RV surge protector, an adapter that helps protect your mobile home from electrical issues such as power surges, popped breakers, blown fuses, electrical fires, and any other electrical problems you might possibly encounter.

What Is An RV Surge Protector?

Believe it or not, a surge protector does exactly what it’s expected to do: protect your electronics from electric surges. Whether it comes from a lightning strike or a faulty wiring system, having one is actually an important, basic safety measure to take. Not to be confused with your basic at-home surge protector, an RV surge protector plugs into the outlet you plug your RV into. When you connect your RV to a power source (a shore power, generator, vehicle engine, or solar panel) at an RV park, you’ll want to make sure that the connection doesn’t burn out your auto electrical system or even go as far as to fry your electronics.

An RV surge protector will serve as a buffer so that your motorhome will have a lower chance of sustaining electrical damage when plugging in. Depending on what kind of your surge protector you get will determine how well your travel trailer can handle surge failure and power issues, and generally, you get what you pay for. Nevertheless, they all work to keep your RV’s electronics safe.

Surge Protector vs. Electronic Management System (EMS)

There are two types of surge protectors, differentiated by their range of protection. While a surge protector can only offer protection from high voltage, an electrical management system can offer protection against high voltage, low voltage, reverse polarity, open neutral, open ground, reverse polarity (incorrectly wiring issues with the power pedestals), power spikes, and many other costly issues. So if you’re RVing somewhere, you’ll start to realize that investing in more expensive, more quality surge protection can actually save you so much more money in the long run.

There’s also a difference between a 30 amp RV and a 50 amp RV electrical hookup, based off how many prongs your camper’s power supply plug has. So while looking for the proper power defender voltage protectors, you’ll have to make sure you buy accordingly, otherwise you might run into even more problems. Below, we’ve constructed a list of some of the best RV surge protectors, so that you won’t have to worry too much about electrical protection while on the road.

1. Hughes Autoformers RV220-50SP Voltage Booster

The Hughes Autoformers RV220-50SP Voltage Booster is both a voltage booster and surge protector, making it a perfect all-in-one purchase.

With LED indicator lights to help you know if the unit is running correctly, you will never have to guess if you’re having problems. Although it’s on the heavier side, it’s also the only U.S. patented voltage boosting solution available, and it can be hardwired into your RV’s ventilated compartment.

2. Camco 55301 30 Amp RV Power Defender Voltage Protector
