Found of riding an RV? This seems like you don’t need a modern invention right now and want to stay connected with nature. Well, this will not make you backward at all. For those who love driving RVs or planning to have one, we are mentioning the best rv surge protector reviews for RV lovers.


Just a quick introduction for RV (recreational vehicle) is a living apartment but on road. This means mobile accommodation for one person or two. RV surge protector protects the electrical system of RV circuit as it can prevent damage to the circuit from overuse. EMS (electrical management system) is a better option that can provide more protection for the surges.

Here are some best rv surges protectors that can keep your work going on.


How To Choose A RV Surge Protector – Buyer’s Guide 

It’s not easy to keep a fully equipped RV in good shape. However, if you frequently drive your RV on holidays, keep in mind that power stations in parking lots and campgrounds do not have a consistent power output, so power surges are always a possibility. However, if you safeguard your RV with a good surge protector, you can minimize the risk and save hundreds of dollars. In this buying guide, we’ll go over some important considerations you should make before purchasing a surge protector for your RV.

Portable or Hardwired

First and foremost, you should be aware that there are two types of surge protectors for RVs: 

  • Hardwired 

The hardwired ones are placed directly in the RV, however, the installation can be difficult, so you may need to employ an expert. The plug-and-play design models, on the other hand, attach between the connecting line, which is rather straightforward and can be done by anyone.

  • Plug-and-play 

Furthermore, plug-n-play models are portable, allowing you to simply transport them or lend them to friends in need. Plug-and-play devices, on the other hand, are more prone to theft because anyone can just remove them and steal them, whereas hardwired models are not. Both portable and hardwired types of surge protectors come with their own set of advantages and disadvantages.

Amperage Rating 

Whether your RV requires a 50 amp or a 30 amp hookup is dependent on your vehicle.

So, based on that, you can make the best decision for your RV. In general, you can tell a 50 amp surge protector apart from a 30 amp surge protector by having a look at the connection pins. 

Surge protectors of 50 amps usually include a four-pin connector with three flat pins and one round pin.

30 amp devices have a 3-pin connector with just two flat pins and one round pin.

Voltage Rating 

Surge protectors that handle 120V power supply are easy to come by since we’ve previously highlighted a number of solid solutions on the list. However, a 240V power source may be available in some locations. Maybe a 120V power surge protection device may not function properly in this instance. As a result, getting a surge protector that can handle the variable voltage of 120V and 240V power supply is a wise decision.

Surge Rating

Next, while purchasing a surge protector for your RV, it is critical to examine the surge rating. If you have a well-equipped RV trailer with air conditioners and other devices like refrigerators, and a variety of other equipment, you’re in luck. 

For appropriate safety, you should invest in a reliable surge protector capable of taking roughly 4000 Joules of electricity. Although such huge surges are uncommon, you should not take any chances here. On the other hand, if your RV has fewer appliances, you might want to look into other solutions that use fewer Joules. For no or low power-consuming appliances, a 2000 Joules option would be fine to go for.


Finally, we always recommend double-checking the warranty on any product you buy. When it comes to RV surge protectors, some manufactures give a lifetime warranty, while others only offer a one or two-year warranty. It’s usually better to choose a surge protector with a longer warranty period so that you can simply acquire a replacement if something goes wrong.
