Best RV Surge Protector Reviews (Stay Plugin’ In)

Getting a short or having your electricals damaged is always a possibility when camping out in your recreational vehicle. Just like most of us invest heavily in surge protectors for our homes, you should consider doing the same for your RV.

Most RVers often ask that all too familiar question, “do I need a surge protector?” Initially, it often seems like an unnecessary purchase until you have to replace several damaged electronics or even have to replace your RV power supply points.  It is obvious, having even the most basic of surge guard is better than never having bought one in the first place. However, it is still better to go for the best of the best as a long-term investment.

We sought to find the best RV surge protectors out there and came up with this comprehensive guide to help get the right one in your motorhome.

An RV Surge Protector Buying Guide

The primary role of a surge protector is to keep your electrical system as well as plugged in electronics safe from electrical inconsistencies.

When researching these units, there is always selections that feature the surge protector tag while others get the EMS branding. That is not the only confusing aspect because just at a glance these products come with quite the hefty price tag going as high as $1000 or more. Therefore, buying an RV surge protector becomes one of those purchases many people put off for a while.

Why don’t we figure out just why you are better off making this worthwhile investment early enough.

What does an RV surge mean?

An RV features several electrical components tasked with keeping your air con running, charging batteries, powering computer-driven elements, and even operating your entertainment systems. The RV needs access to a clean supply of power which is not always possible.

A surge refers to power inconsistencies brought about by several factors. For starters, natural events that are beyond our control such as a lightning strike hitting a transformer can cause surges. When tree limbs or small animals come in contact with power lines, it can also affect electrical consistency. In any of these instances, there might be an outage, and when the electric supply gets restored, it causes a surge.

However, most spikes originate from within when devices that use motors start up and power off several times which keeps diverting the shared electricity between appliances.

Beside surges and power inconsistencies, brownouts and incorrectly wired circuits can also cause costly damage to a recreation vehicle’s electrical system.  That is where the aftermarket devices come in handy to take care of these spikes and surges.

Also, worth mentioning is that RV camping sites have by far the most inconsistent electrical supply. It is often due to a number of issues and therefore without a surge guard you risk the possibility of damaging electronics.

Surge protector or an EMS?

The way a surge protector works is to prevent surges and spikes from passing through to your motorhome. The units typically feature a portable plug-in design that you can place directly on the pedestal before plugging your rig shore power cord.

An EMS (energy management system) does what a surge guard does and more. They come bundled up as advanced computer-aided tools that can control, optimize, and monitor the performance of your electrical system. Like surge protectors, some come in plug-and-play designs while others feature hardwired models that require some form of installation.

To go a little more in depth, an EMS can identify any number of electrical issues and disconnect the power coming to your coach to prevent damage. It then keeps monitoring the situation and only restores the supply once the problem gets corrected. They even go the extra mile to protect you from shock in the case of hot skin conditions due to incorrectly wired outlets or other reasons.

A surge guard cannot monitor or offer protection against fluctuating voltages, revere polarity, and open grounds/neutrals. In any of these cases, it is up to you to check the indicator lights and manually shut down the power supply.

Naturally, the power management systems cost more than your regular surge protector, but when you consider the long-term value, it pays off to invest in an EMS.


It is crucial to match up the wattage of the power guard unit to that of your motorhome’s system. Several elements can create spikes and brownouts.

In brief, when electrical energy temporarily rises beyond the acceptable level on any given circuit, it causes a spike. Brownouts refer to a voltage decrease below the designated level. Either of these possibilities can affect your RV system negatively.

Surge protectors also shield hooked up electricals from voltage fluctuations. The units detect when the source power falls below 104 volts or rises beyond 132 volts. It then shuts down the power and the time indicator flashes to indicate when the AC source goes back up above 104V or falls below 132V. Most EMS units feature a 136-second delay, but it usually varies from one brand to another.

Protection rating

Joules refer to the rated measurement of an energy surge, and you always want to go for an EMS with the highest possible score.

The rating refers merely to the maximum energy levels the device can absorb and then dissipate as heat. In the midst of a power surge or voltage spike, the unit’s protection rating matters a lot because it determines its ability to withstand the excessive supply of power hits and maintain its primary function.

Also, worth mentioning is that surge protectors do not last forever. While you may become aware of some electrical faults early enough and fix them, some may go unnoticed. Eventually, the unit wears out after receiving too many hits from energy overloads beyond its protection rating. Therefore, you should be ready to replace the devices eventually.

Power Strips

Several power strips also provide surge protection in addition to offering extra outlets to plug in your electronics. Despite the cost, not all these electrical extension cables offer the needed protection from power issues.

Therefore, the recommended approach is to use a power strip collaboratively with a surge protector and not in place of the valuable gadgets.

Installation and Configuration

Going back to electric management systems, they often come in two configurations including plug-and-play and hardwired models. The hardwired models require permanent installation, and after that, it gets rid of the need for future setups.

The hardwired models can include remote digital displays inside your camper to enable you convenient access to the power management system. These units also tend to be smaller in comparison with surge protectors.

Naturally, you must have some level of experience with RV electricals to hook one up correctly. Otherwise, you would need the services of an electrician but on the upside is that it only requires a one-time installation.

Is there a difference between 30 amp vs. 50 amp RV

Each motorhome comes with an amperage rating with most Class As and Cs being 30 amps. The motorhomes that have two air conditioners are often 50 amps. The amperage matters a lot when determining the voltage it can handle from a power source.

For instance, 30 amp RVs run on 120 volts and hooking anything above that spells doom. If you are not too sure about your RV’s amperage the first way to tell is by considering the number of air conditioners you have on board. With two air con units, your RV is undeniably a 50 amp. You can also tell by checking the power cord for the number of prongs it has. Three-pronged models are 30 amp, and the four-pronged ones are 50 amp.

The rig shore power running to your RV should never go into a standard home outlet. It all starts with wiring your RV, and you must get the services of an electrician who know what they are doing.

If you are on a budget should you still get a surge protector?

At this point, the consensus is that you are much better off with the least amount of surge protection than throwing caution to the wind. Power strips and mini plug-in adaptors that feature surge protection work as a good in-between for the budget shopper.

The bottom line is to make sure that you have a power guard in place before plugging valuable and expensive electronic devices into your RV’s power outlet.
