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!

1. 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.

2. 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.

3. 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.

4. 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.

5. 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.

6. 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.
