The Best RV Surge Protectors in 2023

Anyone who owns an RV (recreational vehicle) knows that it’s not exactly cheap to fix it if one or more things get damaged. There’s much more going on in an RV than there is in a car, meaning there are more things to get damaged. Electrical surges are among the most common problems that can occur if not handled with care and necessary precautions.

There are many devices that require power inside this type of vehicle, such as a special RV refrigerator, cooking appliances, even a washing machine, and lots more. That’s why looking for the best RV surge protector out there will save you a lot of money, time, and worries.

We’ve listed some of the best ones in this article and have prepared an RV surge protector buyer’s guide so that you will know which one is best for your RV.

How to Choose an RV Surge Protector

When it comes to electricity and protecting yourself and your RV from it, you should always find the best possible way to protect, as safety should never be overlooked. Look at it this way. If something like a power surge destroyed your RV’s appliances, you would end up paying significantly more than what it would cost in an RV surge protector.

Such a surge could hit anything from the coffee maker in your RV to the battery full of electricity that your RV generator produced at some point. If you want to protect your RV, check out our top picks for surge protectors above and listen to what our buyer’s guide has to say in order to get the best one specifically for your situation.

These are a few of the things you always need to consider before making a purchase.

Amp Rating

The amp rating of a surge protector is actually one of the easiest steps when trying to find the best one for you. All you have to do to get this right is to look at what the pedestal outlet and your RV specify in terms of amps and buy the corresponding surge protector. In most cases, the most common choices are a 30-amp and a 50-amp RV surge protector.

Joule Rating

The most important thing you’re going to need to know about the joules rating is that the higher the joule surge protection specified, the better for you. However, not all RV surge protectors have the same rating, as this generally affects the price and other specifications of the protector.

The joules rating specifies the maximum amount of energy measured in joules the surge protector will be able to absorb and export as heat. This is why higher will always be better. If a surge protector that can only absorb 1500 joules was hit with more than that, then it would give out and possibly do a lot of damage. That’s why you will always want to look for one that protects your RV from dangerous power surges.


When ease of installation comes into question, there are two main types of RV surge protectors out there. They are known as portable and hard-wired. The portable ones are usually a lot easier to set up, while the hard-wired ones will require professional help from someone who knows what they’re doing.

If you want to avoid all of the hassle and risk from setting up a hard-wired one yourself, you will want to purchase a portable one with decent specifications. Luckily, there are many commercial brands that provide easy to set up RV surge protectors that will protect your RV from a significant amount of electricity.

Indication and Notification

One of the best features an RV surge protector can have, besides protecting your RV from surges and other wiring faults, is its ability to notify you when something bad has happened or is about to happen. Most of the best ones will have LED indicators that light up in such a case, but as you’ve seen from one of our top picks above, some surge protectors will even send a notification to your phone, informing you of such a situation.

It’s important that you’re notified when a surge occurs, but some models with LED indicators are hard to read during the daytime. It’s not extremely necessary but try to purchase one that will clearly indicate and not leave you in the dark.


You might have noticed something buzzing loudly at another RV near you. In most cases, this is usually coming from a low-quality RV surge protector that continually emits an annoying sound. This won’t affect the surge protector’s ability to protect your RV from surges in any way, but it will make you and your neighbors very uncomfortable after a while. If you’re seeking at least a little bit of comfort, then look for one that has a low noise level.


An RV surge protector is a necessary tool for preventing any wiring and electricity issues from harming your RV and its appliances. Something such as a surge can affect your fridge, water heating equipment, your RV solar kit, and other expensive equipment. But, deciding to buy one is only part of the process.

You also need to know how to purchase one and what to look for in order to make a great decision that won’t waste any time or money. Follow the tips in our RV surge protector buyer’s guide and definitely consider the choices we’ve researched and showcased above.
