Surge Protector RV Buying Guide

Best RV Surge Protector 2017 - 2018

Types of Surge Protectors

The following are the two most common types of surge suppressors, the hardwired and the portable.  They have big differences, so it is important that you select based on the following information and your needs.

Portable Surge Guards

These units do not require installation. They are plug and play surge suppressors that you can connect directly into the pedestal. Just like their hardwired counterparts, portable units ensure that there is no faulty power from the park line to prevent damage to your vehicle and equipment inside it.

They also warn you of potential dangers including incorrect voltage supply or amperage. Many of them are also weather resistant, so they can be used even when it is rainy or windy.

One of the most loved features about these portable devices is they’re convenient to use anytime. You can connect them to the outlet of the pedestal fast without wiring work.

They are built with durable features, including T bar handle or dog bone styles. These portable units also have LED light indicators that warn you in nanoseconds in case there is danger due to spike fluctuations, including when there is high or low energy voltage from faulty electrical wirings.

Hardwired or Permanent Surge Protector for RV Campers

They are permanent surge guards that you need to install inside the RV or in the compartment where the power is coming from.

Hardwired units keep your RV protected all the time because they are always plugged in. Forgetful people should get this one to prevent the risk of forgetting if they have plugged it in their RV.

The protector is always attached to the components of your vehicle, so you don’t also have to worry it being stolen as well.

Which to Buy: Portable vs Hardwired

Best RV Surge Protector 2017 - 2018

Portable units should be physically hooked up to the park’s pedestal before you plug it into your RV. You do not have to do wiring work to hook it up, though.

These devices are also easy to replace than hardwired models are. If one sacrificed itself, you can buy a new portable unit, do the same procedure and you’re good to run again.

On the downside, portable units can be stolen (but you can buy locks to prevent it). Another is you might forget plugging it in or you might leave it behind.

Additionally, portable units tend to drag on the ground such as if you’re plugging it into a short power park pedestal, or if you’re hooking up to a 30-ampere and need a 30-50 amp adapter cable. Finally, some models are rather bulky, so you would need to put it on a bucket to raise it during the rain.

Hardwired models are permanent or fixed inside your RV. Many are hardwired or mounted inside the vehicle or next to the power reel.

For the advantage, hardwired models are less likely to be stolen, as one is fixed inside the vehicle and hidden in view.  Thus, you don’t need to buy a lock to secure it in place and make sure it is still there when you’re about to leave.

With one, you don’t also have to worry about hooking anything up. Users also reported convenience of not having to worry if they forget plugging it in or leaving it behind.

A hardwired best rated surge protector also prevents issues of dragging on the floor even with short power pedestals or contacting with water or rain.

One is also smaller than portable models, so you should go for it if you’re trying to save space. On the not so good side, you need to do some wiring work to mount it.In the event it fried itself for a sacrifice, you need to do another wiring and spend extra work to replace it before you could go running again.

What to Look for When Buying Surge Protectors

Best RV Surge Protector 2017 - 2018

1) Amperage Rating: Buy a 30-amp unit for a 30-amp rig or a 50-amp one for a 50-amp rig. In short, match the amperage rating with the amp requirement of your RV. Doing so will lessen overheating, fire and other electrical concerns.

2) Joules rating: Protection rating is measured in joules. The device will dissipate heat if there is too much energy because of energy spikes. Find one that can protect your RV from potential overheating by looking for one with the proper joules rating.

3) Weight: Another factor when choosing a surge suppressor, weight is important if you constantly travel and you’re buying a portable unit. The same goes for hardwired models. One must not add much weight to what your RV should carry.

4) LED display indicator lights: Some models are hard to read at daytime. Find one with a bright LED readout to avoid any difficulty. Remember the indicator lights act as cautions, so they should be clearly visible even at daytime or when raining.

5) Less noisy operation: Some units make much noise when running, causing distraction and annoyance when your vehicle is parked in a quiet place. Look for one that makes less noise than others do.

6) Protection features: If you need intelligent features, opt for one that also protects your RV from other types of power problems aside from surges.  For one, having an accidental 240-voltage protection is useful especially if you plugged the cord into a pedestal that is incorrectly wired to 240 volts.


Portable surge protectors are your fist line of defense against bad power supply. Portable or hardwired, these devices protect your RV from power sags and surges that would otherwise harm your investment.

These surge suppressors are also sacrificial, cutting off the power if it’s damaging for your RV. In worst cases, such as a big power surge, one will fry itself and cut off power totally.

In today’s RV surge protector reviews, the clear winner is the Progressive Industries EMS-PT30C Surge Protector.

It offers protection both for under and over voltage, has one of the highest rated at 3800 joules and checks polarity. Most importantly, it has smart features, including an accidental 240V protection.
