10 Best RV Surge Protectors 2022

It has become an increasing challenge to find the best RV surge protector for home use. With so many brands and models available in the market. That’s why it’s difficult for consumers to know which one will work right for them.

However, looking for the best RV surge protector? The 10 best RV surge protectors are reviewed here. They range from a simple plug-in model to a more sophisticated device & good for installing on your home’s electrical panel. You can find one that fits your needs and budget.

What Is RV Surge Protector?

RV surge protectors are devices that plug into a regular outlet and then connect to an RV’s power cord. In the event of a power outage or poorly grounded campsite, they help prevent electrical surges from damaging any appliances or electronic systems. 

When people have full-time jobs and can’t tell their schedule for two weeks, they might not be near when there is an unexpected power outage.

It’s important to note installation should be done by qualified electricians only because it entails dealing with 220-volt circuits. Also, you should understand how electricity works in RVs.”

RV surge protector protects you from these four things.

  • Power spikes: Power spikes are sudden, brief but occear high voltage electrical fluctuations.
  • Sags and brownouts: Sags and brownouts are longer periods of low voltage which can cause damage to your appliances.
  • High electromagnetic noise: High electromagnetic noise is another cause of damaging electrical appliances.
  • Overloads: Overloads are sudden bursts of power that can cause damage to your home device.

Kinds of RV Surge Protector

There are different types of surge protectors that you may need to choose from your needs. The most used RV surge protector types are:

(1) The Battery-Operated Cordless One:

This kind of RV surge protector is the most accessible and commonly used. Many people consider it as a ‘must have’ for their RVs. It’s easy to use because you simply plug your cord into it then plug the surge protector into any standard 120-volt outlet. You can also use it to charge cell phones and laptops while on the road. 

Cordless surge protector is compact, lightweight, and portable. They are also easy to install & most of them have a simple plug-in indicator light.

Battery operated RV surge protectors can be able to turn off your appliances automatically when it detects an electrical problem such as voltage surge or spikes.

(2) The Wired Indoor Surge Protector:

In comparison to a battery-operated surge protector, it’s more complicated to use. When you buy a wired model, you’ve to be aware of rough handling which may complicate its functionality. 

You’ll need an electrician for installation either to your electrical panel or directly to your home’s main fuse box. This kind of RV surge protector is ideal for RVs that are hooked up to a permanent power source.

(3) The hardwired Indoor surge protector:

Hardwired indoor surge protectors are also tricky when it comes to installation. An electrician should be able to connect the device directly to your home’s main fuse box or directly into your electrical panel. This device is more preferred by RVs that are hooked up to a permanent power source such as campsites or RV parks.

(4) The combination of wired and battery-operated surge protectors:

You can combine these two types in order to have the best protection for your recreational vehicle. There will be an easy installation since it only requires connecting the battery-operated surge protector to your RV’s cord while you already have a hardwired one connected to your home electrical panel or fuse box.

FAQs about RV Surge Protectors

Are surge protectors expensive? 

Surge protectors may appear to be expensive at first glance. But they are a wise investment considering that they can help in preserving the useful life of your recreational vehicle appliances.

What can I do with an RV surge protector outlet/plug?

It’s best to use it with power cord management and organizing by plugging all your electronic devices into one outlet.

What is the difference between a surge protector and an adapter?

A converter/adapter is different from an RV surge protector since it changes voltage levels only when power surges occur.

Whereas a surge suppressor can also be used for reducing electromagnetic interference as well as line spikes.

How does a surge protector work in an RV?

A surge protector works by redirecting up to 70% of the power surges caused by conditions such as heavy rain, wind, or lightning strikes from destroying your recreational appliances. It’ll help in preventing electrical sags and interruptions to occur which may damage sensitive electronics.

What’s the difference between a 30 amp and 50 amp surge protector?

The main difference is that a 30 A is 3x more power than a 50 amp. Also, 30 amp RVs can receive up to 3,600 watts and 50 amp RVs get 12,000 watts. This means that the longevity of a unit may be affected if more power than it can handle is drawn from it. The cost difference is about $10-$100 depending on the brand.

Do I need an RV surge protector?

Unless you want to replace your electrical appliances with new ones every year, I’ll strongly advise that you invest in an RV surge protector. This device will help in the prevention of power surges and spikes which are common occurrences.

Why do I need an EMS over RV Surge Protector?

The best use of such a device is to prevent damage and warnings from power surges. If anything does happen then it’s best to have an EMS, as they offer more protection than RV surge protectors.

RV Surge Protector vs. Electrical Management System (EMS)

The main difference between these two is that an EMS provides more protection than RV surge protectors. This is because it can shut off power, reroute voltage and monitor vital electrical components in a recreational vehicle.

Is a RV surge protector worth having?

The Issue with plugging your device into a bunch of constantly changing power sources is that you never know what electricity is coming out of the socket. This means that the more devices you plug into one socket (especially heavy-duty ones), there’s always a risk of things going wrong like blowing fuses, tripping breakers, resetting timers, frying circuits, etc.

So to protect all devices of your home from any spike, you should use a good-rated RV surge protector.

In Conclusion

We hope you’ve found this article helpful in your search for the best RV surge protectors. Given that surge protectors are not a necessity for everyone’s RV, they are an important investment to help you protect your valuable electrical system.

On the other hand, if you don’t already have one in place and want a ground-fault interrupter or a surge protector with even better performance, we highly recommend the Southwire 34930 Surge Guard.

This RV surge protector is designed to work on all types of RVs and with the new ‘Clean Power’ Filtering Technology in place, will help to reduce any interference or unwanted noise for optimal operation of your electronic appliances.

We hope you have found this article helpful in making an informed choice on the right RV surge protector.
