Having electricity while traveling in an RV makes your every day life convenient. When RVing, we use a power pedestal while staying at campgrounds to power up our appliances, lights, and even laptops in the motorhome. But we also have to make sure that the appliances are not damaged in any way when there’s a power surge or ‘brown-out’ and incidental voltage spikes. 

There’s NO WAY I’m letting our beloved kitchen accessories and appliances get damaged!

This is where the RV power surge protector comes in. It protects your appliances from overloading when power surges occur. It’s usually placed on either a surge protector or EMS before the power cord. It also protects your whole place from any RV electrical system problems.

As vital equipment for full-time RVers ….and ‘anytime RVers’, you have to find the best RV protector surge for you!

​How does a surge protector work for an RV?

Right now you might be asking “what does a surge protector do?”

Surge protectors are basically used for your RV electrical protection. Power surges do happen and these may damage the appliances you have onboard or your entire electrical system. To solve these common RV electrical problems, it’s best to have a surge protector with you.

Do surge protectors work?

Definitely! It is a must-have for every RVer! You’ll never know when power surges happen so to prevent any electrical problems, especially for us full-timers who rely a lot on the limited appliances we have in our RVs, we should have our trusted surge protectors!

We have our Progressive 30amp at every campground and it’s cut the power off to our RV several times during surges and has saved our appliances and electrical system several times over!

Best RV Surge Protector Brands

Which RV surge protector is best for your camper?

Not many brands focus on supplying surge protectors but a lot of companies produce it as one of their many products. Among these companies, 4 have caught our eye with their high-quality surge protectors.

Read on to see which of them made it to our list!

1. Progressive Industries

True to its name, Progressive Industries is TRULY progressive and has been a top brand when it comes to surge protectors for years now. Not only that, they continue to make innovative upgrades while maintaining good prices for their customers!

What makes them appeal to consumers aside from the price is the lifetime warranty that comes with their products. Maybe it’s because the owners are fellow RVers so they know exactly what we want and need. 

Almost every Progressive RV surge protector is worth buying!

2. Technology Research (TRC Electronics) 

As a company that specializes in power supply products, TRC Electronics is able to easily integrate new features to its products. They have been in the field since 1982, so that’s proof that they can be trusted. However, surge protectors do not seem to be the brand’s main product.

Despite this, you’ll see their company name once you search for lists of the best surge protectors EVERY year. They’ve got some fans!

3. Hughes Autoformers  

Hughes Autoformers focus on only two types of products, voltage boosters and surge protectors. And that’s a smart combination because who’s willing to buy and use voltage boosters if they don’t have a surge protector to assure safety?

The company also made a great product by integrating both functions in their Hughes Performance RV22050 Autoformer. This product can boost voltage while keeping it safe with its surge protection.

We can’t wait for more innovations like this from Hughes!

4. Camco 

Looking for a portable surge protector for RV? Camco’s got it!

With their focus on camping essentials, Camco also benefits RVers like us with their products! They may not necessarily focus on innovating their surge protectors but the ones they offer have good quality at affordable prices.

If you’re starting out and want to try cheaper tools that may work for you first, we recommend getting a Camco camper surge protector. Yet, if anyone asks which brand to go with if they want the best we always recommend Progressive!
