6 Best RV Surge Protectors in 2021 Reviews & Buying Guide


If you are the owner of a well-furnished RV or trailer that you frequently use during vacation times, you must have spent thousands on it already. Generally, when you visit any campsite, dealing with electrical surges is pretty common. In that case, the electronics present in the RV, such as refrigerators, ACs, etc., can get heavily damaged.

So, it’s better to stay prepared rather than to regret any mishap. That said, we have come up with some of the best RV surge protectors out there that can help you keep your RV protected from electrical damage. A decent RV surge protector might cost around $100-$350, but you should keep a few things in mind before buying one:

  • Hardwired or Detachable: There are basically two kinds of RV surge protectors, Hardwired and Detachable ones. While the detachable ones are super-easy to install as they simply plugin, and start working. The hardwired models are essentially installed inside your RV, so the one-time installation is complicated, but no one can steal it, so it’s also good in that way.
  • Amps Rating: Depending on the circuitry of your RV, you have to confirm whether your RV requires a 50 Amps connection or a 30 Amps connection. Choosing the right one for your RV is important otherwise, it may make things worse.
  • Surge Rating: When it comes to handling electric surges, each surge protector has its own capabilities. While most 30-amps surge protectors are good to handle up to 2000 Joules of electricity, 50-amps options may survive up to 4000 Joules before showing any signs of failure.

That’s what’s most essential to check before you spend your money on a surge protector for your expensive RV, but there are a few more things that you can consider and make your purchase even more worth it. To know such factors, you can consider reading the “Buying Guide” that’s mentioned below in this article.

Buying Guide for the Best RV Surge Protectors

We understand maintaining a fully-equipped RV is not that easy. That said, if you frequently take your RV out for vacations, power stations present in the parking areas and campsites do not have a stable power output, so there’s always a risk of power surges. However, if your RV is protected with a decent surge protector, you can stay out of the risk and save thousands. In this buying guide, we will discuss some crucial factors that you should always check before buying a surge protector for your RV. Let’s start!

Type

First of all, you should know that there are two kinds of surge protectors available for RVs, Hardwired and Plug-and-Play models. The hardwired models are directly installed in the RV, but the installation is a bit tricky, so you might need to hire a professional for that. On the other hand, the plug-and-play design models attach between the connection line, which is pretty simple, and anyone can do it on their own.

Moreover, they are portable as well, so you can easily carry them, or even lend them to your friends in need. However, the plug-and-play models are more vulnerable to theft as anyone can simply unplug them and steal, which is not the case with hardwired models. So, both types of surge protectors have their own pros and cons.

Build Quality

Once you pick the right type, you should take a look at their build quality. Generally, the hardwired models are better here, since they are installed inside the RV, so they are less prone to damage. However, in the case of plug-and-play devices, you should check if the surge protector is weather-resistant or not. The surge protectors, which are weather-resistant, can be used in rain, storm, etc., while you can relax in your RV on the vacation. Otherwise, you will have to keep an eye on the weather all the time and use it cautiously.

Amps Rating

It depends on your RV, whether it uses a 50 amps connection or a 30 amps connection. So, depending on that, you can pick the right pick for your personal RV. In general, you can distinguish between a 50 amp and 30 amp surge protector by looking at their connection pins. The 50 amps surge protectors usually have a 4 pin connector where 3 of them are flat, and 1 is round. On the other hand, 30 amp devices come with a 3-pin connector featuring only 2 flat pins and 1 round pin.

Voltage Rating

You can easily find surge protectors that support 120V power supplies, as we have already mentioned a lot of good options on the list. However, at some places, you might find a 240V power supply. In that case, your 120V power surge protector might not work properly. Hence, the good choice to make here is to get a surge protector that can deal with both 120V and 240V power supplies.

Surge Rating

Next up, considering the surge rating is quite an essential factor while buying a surge protector for your RV. If you have a well-equipped RV trailer that boasts Air Conditioners, refrigerators, and a bunch of other appliances. You should spend your money on a good surge protector that is capable of handling around 4000 Joules of electricity for proper protection. Although such high spikes are very rare, you should not be playing risky here. On the other hand, if there are lesser appliances in your RV, you can consider other options with fewer Joules, such as a 2000 Joules one.

Warranty

Lastly, we always recommend checking for the warranty for any product you purchase. In the case of RV surge protectors; there are several brands that offer lifetime warranty while the others provide 1 or 2-year warranty. It’s always better to pick a surge protector which has a longer warranty period so that you can get a replacement easily if something wrong happens with the product.

Conclusion

We hope you have liked this list of the best RV surge protectors. As you can see, we have included all kinds of options in the list, which have different prices as well. That said, there’s a surge protector for everyone on this list. By now, we assume you already have a few considerations in mind to get your hands on. However, if you are getting confused between all the good options, we have a few personal recommendations for you:

  • If you are looking for a hardwired model, the Progressive Industries HW50C Hardwired EMS Surge is one of the best options to pick. It’s a 50 amp option that comes with 5-mode surge protection. Moreover, it’s ideal for both 120V and 240V supplies and comes with a lifetime warranty.
  • In the 50 amps category, if you want to choose a plug-and-play design surge protector, there’s no better option than the Camco 50 Amp RV Power Defender Voltage Protector. It features 4200 Joules of surge protection and is completely weather-resistant as well.
  • For those people who are looking for a 30 amp model, pick the Southwire 34930 Surge Guard 30A surge protector as it provides full protection against every wiring fault, and also comes with an anti-theft locking feature.
