Diagnostic LEDs alert you to problems, and it also comes in a 50-amp version for bigger motorhomes.

Recap: Best RV Surge Protectors of 2019


Things to Look Out For When Buying an RV Surge Protector

Because this device protects your investment, it’s essential to arm yourself with some critical information before buying an RV surge protector. Here are some things you need to know.

Types of RV Surge Protectors

There are two types:

  • Basic surge protectors: these devices do exactly what their name suggests. They protect your RV against unstable electricity at RV parks.
  • Complete surge protectors: these devices offer a higher level of protection and come with a correspondingly higher price tag. Some come with electrical management systems that bolster RV protection. Their protection includes things like faulty wiring, high and low voltages, and open ground.

We recommend complete surge protectors, which (despite being pricier) provide much more comprehensive protection than basic ones.

Amperage

If you only pay attention to one thing when purchasing an RV surge protector, it should be amperage. There are 30-amp and 50-amp versions, and you must get the right one for your rig.

It’s easy to figure out which one you need. Look at your rig’s power cord. If it’s got three prongs, you have a 30-amp rig, which is typical in smaller campervans. If the power cord has four prongs, you’ve got a 50-amp rig, which is generally the case for motorhomes.

Diagnostics

Surge protectors have evolved to be incredibly sophisticated. Modern versions use diagnostics to detect issues in the power supply and alert you if there’s a problem. These capabilities are quite handy when visiting new campgrounds with unknown power supplies.

LED Display

When the diagnostics that we just mentioned detect irregularities, they use a LED display to let you know. It may seem like a trivial point, but the LED should be easy to read. It should also be bright enough for daytime use, which is a problem with some surge protectors. And though it may sound obvious, it’s critical to check the LED before plugging anything in.

Level of Protection

Not all RV surge protectors are created equal. The level of protection they provide will vary from device to device, and this is another critical factor to pay attention to. Some useful safety features include automatic problem detection, emergency shutoff, and indicator alarms. After all, what good do diagnostics do if you have no way of knowing about the problem?

We recommend getting a surge protector with extras like these because they can be key in protecting your electronic devices from damaging high or low voltage that will cost you money.

Joules Rating

You’ll notice a joules rating when shopping for surge protectors. The joules rating essentially tells you how much protection any given device will provide your rig. A surge protector should disperse heat in the event of a power spike. The higher the rating, the more effective the device is at preventing overheating.

Joules protection becomes especially important when you’re looking for devices with a longer lifespan and fuller protection.

Portability

Finally, you must consider portability when purchasing an RV surge protector. These devices are available in either portable or hardwired versions. Portable surge protectors are generally cheaper and weigh less. It’s also quicker to get them up and running since you can install them yourself.

Hardwired surge protectors, on the other hand, require professional installation and cost more. They do have one advantage over their portable counterparts. Because they are hardwired, you won’t have to worry about them being stolen. Though the counterargument is that many portable surge protectors include locks, and you can buy them separately if they don’t.
