Best RV Surge Protector for 30 and 50 Amp RVs

Updated May 17, 2023

Investing in an RV surge protector won’t break the bank either; they’re actually quite affordable. In fact, buying one could save thousands of dollars in repairs down the road. As far as electrical components go, RVs can be downright scary.

The lack of reliable grounding, multiple wires packed into small spaces, and many other elements make them a prime location for power surges to occur.

So while you might not be traveling through super storm areas and other weather conditions that can damage your RV, it still doesn’t mean that a potential electrical threat won’t happen while you camp and travel.

An electrical surge protector is the best defense against such incidents, which is why many good surge protectors are on the market. These nifty devices will help protect your electrical system from harmful voltage spikes that might otherwise cause considerable damage.

This article will describe the top 5 RV surge protectors on the market and why we think they’re great options to have in your RV.

Do RVers Require an RV Surge Protector?

The answer is yes, and we’re going to tell you why!

RV surge protectors are designed to protect your appliances from power surges, which can damage them or even start a fire. While most people think about their televisions and computers when they think about power surges, appliances in your RV are also susceptible.

Because RVs have so many different types of appliances, it’s crucial that you use an RV surge protector to protect them all.

A Surge Protector Protects Your RV Against 3 Things

As we’ve explained above, a surge protector is your first line of defense against damage to your RV. And while it isn’t a complete solution to keeping your electrical system safe, it will help protect you from three major problems: power surges, incorrect wiring, and low voltage.

Power Surge

Power surges are one of the most common causes of damage to electrical appliances, and they can also cause serious problems in your RV.

So it’s not uncommon for a surge protector to protect your RV from surges up to 1,000 volts—which means they’ll protect against the kind of surges you might experience in a thunderstorm or when your car battery dies.

Incorrect Wiring

Improper wiring can cause a fire in your RV, which can be very dangerous if you’re camping or traveling on the road. Improper wiring can also cause problems with your electrical devices, including lights, TVs, refrigerators, and more.

A surge protector will help protect against improper wiring and prevent fires from occurring in your RV.

Low Voltage

Low voltage can cause lights to flicker or go out completely when there isn’t enough power being supplied by the generator or solar panels installed on top of your RV roofing system.

This problem can also cause appliances such as refrigerators to stop working correctly due to lack of electricity available for them during periods where there isn’t enough sunlight shining down upon them during daylight hours (when most people are sleeping).

30 Amp or 50 Amp: Which is My RV’s Connection?

You might have heard that two different types of electrical connections are used in RVs: 30 amp and 50 amp.

Smart Surge Protector

You may be wondering which one your RV needs or whether you need an adapter if you have a 30 amp connection but want to use something that requires a 50 amp connection.

The end of your RV’s power cord contains the number of connector prongs, and by looking at this prong, you can determine your RV’s connection type.

If your RV has three prongs on the end of its power cord, two of which are larger than the third, it is a 30-amp connection. If it has four prongs on end and two larger than the others, it is a 50-amp connection.


If you are planning a road trip or living in an RV, it is highly recommended that you have some protection for your electrical equipment.

The power surge on coach buses can cause serious damage to the electrical equipment in your RV, and having the proper protection is crucial to minimizing problems down the line.

Night In A RV


It isn’t just a trip to the hardware store either—you shouldn’t skimp on price. Instead, choose a reputable brand, such as the Technology Research Surge Guard or the Hughes Spike Power Watchdog. And remember that paying more upfront will save you money in the long run.
