These appliances are powered by a power pedestal but sometimes they may cause damage to your electrical appliances.

This is why you will need the best RV surge protector to provide you with protection during your trip. This article is here to give you information so that you can choose the right model. We will be discussing all the things you need to know about RV surge protectors. Not only that, we’ll also feature the five great picks for your RV.

What is a Surge Protector?

Before we proceed with the discussions, let us first define what an RV surge protector is and its benefits. A surge protector is basically an electrical device you use to protect electrical appliances from sags and surges. In case an unwanted power voltage supplies your device, the surge protector blocks it. To define power surge, it is the instant increase in the power supply, which can cause overwhelming damage to your appliances.

The surge protector is a device, which acts like an electrical gatekeeper. They monitor many aspects of the power supply, and it provides protection from destructive electrical issues. You may lose hundreds of dollars, especially if you have a high-end unit, in the event a power surge occurs. They are considered most useful in cases of electricity spikes. Depending on the model, this device is simple and very easy to use.

Normal electrical sources and outlets do not have the appropriate protection from power surges. If you have surge protectors fitted to your power plugins, you don’t have to worry about its security in your RV. One great thing about surge protectors is that they protect your appliances from spikes caused by lightning and short-circuiting. They also act as bridges between the appliances using the power and the incoming power.

Types of RV Surge Protectors

In this section, we will discuss the two most popular types of RV surge protectors: the hardwire and the portable. There are big differences between the two, so it is important that you will be able to set them apart. This section might also help you decide according to your needs and preferences.

  • Hardwire: The hardwire RV surge protector is firmly attached to your RV’s internal components. You can find them in the compartment where the wiring that draws power is. It is always on when you are connected, so you don’t have to worry about it being safely protected. Lastly, you don’t have to worry about it being stolen, as it is directly wired into your RV.
  • Portable – The portable RV surge protector is very convenient to use, because they do not require installation. It is also connected directly to the outlet of the electrical pedestal. The portable ones are specifically designed to warn you about any potential dangers from spike fluctuations. This type will give you caution in case there is low and high-energy voltage due to faulty wiring.

Essential Factors to Consider in Choosing the Best RV Surge Protectors

Before we conclude, we will talk about what properties make a good RV surge protector. You may assume that all of them are great, but there are features that make one stand out against others.

  • Amp Rating: It is indicated in the surge protector the power you will use when you plug your RV. You should choose a surge protector that is appropriate for your use. Doing this will lessen the risk of fire, overheating, and various electrical problems.
  • Joules Rating: You also need to check the protection rating, which is measured in joules. If there is too much energy due to spikes, the surge protector should dissipate the heat. You should look for a unit that can protect you from dangers that can occur due to overheating.
  • Ease of Installation: You should choose a model that is easy to use and install. We can all benefit from the instruction manuals but for beginners, installation should always be easy.
  • Weight: Weight is also a very important factor especially if you wish to transport your RV surge protector. You should choose a unit that is lightweight and must not add significant weight to your RV.
  • Price: A good RV surge protector should not always be expensive. There are lots of cheap ones that also perform well. You just have to weigh your options so you can evaluate better.
  • LED Display: Almost all of the models presented above have displays that also act as indicators or cautions. Some of them are hard to comprehend during daytime and nighttime. You should choose one that has a bright display so you won’t have any difficulty in reading.
  • Plug and Play: Ease of use is very important, especially for beginners. Plug and play is preferred by more experienced RV enthusiasts, as it does not require much time to operate.
  • Noise: Some models generate noise when it is being operated. It can be distracting and annoying especially if your RV is parked somewhere quiet. Choose one that creates less noise compared to other models.
