The Best RV Surge Protector To Prevent Damage To Your RV

Last Update:

If you are in a hurry and just want to find out what the best rv surge protector is, then we recommend the Progressive Industries EMS-PT30X RV Surge Protector as the best one.

When you are out on the road, the last thing you want to deal with is any form of mechanical or electrical problem. There is a lot that can go wrong, and unless you have a ton of technical know-how, you may find yourself stranded or without power.

A surge protector keeps all of your electrical equipment inside the rig safe in the event of a severe power surge or improper wiring. Unless you are a master electrician, we highly recommend keeping a surge protector with your RV.

We’re going to include the following surge protector reviews:


RV Surge Protector Buying Guide

This product is something that is more difficult to understand than a lot of the things you buy for your RV. There is some technical jargon that you wouldn’t know unless you have experience dealing with electrical, but it’s not as complicated as it seems.


Amps are the amount of electricity that is currently available in an electrical current. This means that every device has a certain amount of power it needs to function correctly. If the item does not have that right amount of electricity, then it may fail or have a hard time performing its job.

This is one of the most important things to consider and be sure to read up on the requirements of your RV and its components. Having the wrong surge protector or one that is not strong enough could put you at risk for overheating and ultimately fire.

Joules Protection

This refers to the amount of protection you get in the event of a surge. Joules is the unit of measurement for electricity so it is difficult to understand precisely how much protection you need because you don’t know what type of surge you may get hit with.

Most units that you buy will describe the protection, and what you have protection from anyway, so you do not have to worry too much about joules, it’s just right to be informed.


You want a surge protector that is easy to read and offers nice bright lights that describe the situation well. If the protector is hard to understand you may not realize there is an issue when there is.

A lot of the time the flashing lights are not well described as to what each light means, and that can be even worse than not picking up a reading at all. You might read it and get confused thinking there is a problem where there isn’t.

Most of the high-quality surge protectors describe what each light means right next to it, that is what you want to get if you can.


How easy is the surge protector to install? It’s a simple device, but it is not something that you want to play around with. You want everything to be straightforward and easy to understand so you can protect yourself and your family from any issues.

It should come with an instruction manual for how to install it and what everything means. Some are more complicated, but most plugs in and you’re good to go.

Power Management

This is not something you get with every surge protector, but some of the more expensive ones offer a total power management system. This is something to consider because you get a lot more for your money with these. Instead of just being notified of abnormal conditions in your RV, the power management system shuts everything off for you when there is an issue.

So if there is a power surge, the device will detect that and kill power to the entire RV. Once the power is off the protector will go on a timer, and it will not turn the power back on until everything has settled.

This offers you a lot of protection and I’m sure you have a lot of money poured into your RV. (as everyone does) Why not get the best protection you can? It’s much better than having to deal with electrical failures and cooked wires.

This one functions similar to the previous brand, but we wanted to include this one as well because it is more affordable and is almost equal in functionality.The company that makes these is highly focused on electrical protection technology and has an excellent reputation.

This surge protector protects against all the urgent situations like lightning strikes, power surges, and improper wiring.

The main difference between this surge protector and the previous is that this is not an electrical management box, so it does not notify you if there is low voltage and it does not automatically disconnect if it detects open ground or neutral polarity.

This surge protector is affordable and functions similar to the previous two. The primary purpose of it is to notify you via flashing lights that there is some inconsistency in the electrical current. This causes damage to the electrical of your rig.This surge protector does not protect you against small variations and is more intended for substantial and significant issues that would cause a lot of damage to your RV.

The protector has a max spike current of 6500 amps so if there is an issue it notices immediately and will notify you via flashing lights.

It does come with a lock too so once you install it you do not have to worry about it getting stolen from your RV.

This is another electrical management system that is intended for complete and total protection against any electrical issues in your RV.This device comes in a 30 amp surge protector or a 50 amp surge protector variation, and does a lot more than notify you of spikes or abnormal readings – if the surge protector picks up something that is not normal, it will shut off power to the entire RV and set itself on a timer to protect any compressors.

Ones the time is almost up it will take another reading, if everything is right it will return power to the RV. This is the ultimate form of protection against electrical surges.

The device itself is kind of bulky, and it also does not come with any theft prevention method. If you are spending money on something like this, you want to ensure your protection. We recommend looking into a surge protector lock that will fit over it.
