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

However, The below 9 RV surge protectors are reviewed here. They range from a simple plug-in model to a more sophisticated device & good for installing on your RV’s/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. Especially in this condition, a good quality surge protector will be a helpful friend to protecting home devices.

But 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, and brief but have 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 can choose from your needs. The most used types are:

  • Battery-Operated Cordless
  • Wired Indoor Surge Protector
  • Hardwired Indoor surge protector
  • Combination of wired and battery-operated surge protectors

(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 can simply plug your cord into it and 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. 

A cordless surge protector is compact, lightweight, and portable. They are also easy to install & most of them have a simple plug-in indicator light. Also, it can be able to turn off your appliances automatically when it detects an electrical problem such as a voltage surge or spikes.

(2) 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 RV’s 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) 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 RV’s main fuse box or directly into your electrical panel. This device is preferred by RVs that are hooked up to a permanent power source such as campsites or RV parks.

(4) 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 an electrical panel or fuse box.
