This 30-amp voltage protector helps protect your RV from damage caused by low or high voltage and power spikes and surges. It automatically disconnects when dangerous voltage levels are detected and reconnects when voltage levels stabilize.


I have used the surge protector at RV sites and at home. I can be assured my Roadtrek is protected against faulty wiring and power surges. It is easy to use, and ruggedly built.


Hasn't failed yet. Only issue is it is bulky to pack. Status lights a real help.


etrailer has become my new "GoTo" company for my RV needs. My Camco 30 Amp surge protector was here in two days. and we use it this weekend. It worked as advertised, but that is what you would expect from Camco. The etrailer price was lower than any place else, including other sites.

Still very pleased with the Camco surge protector. We use it at every site that we stay. We camp at a lot of COE parks, some of which have been around for awhile. Given the age of some of the COE infrastructure, at least we know our electronics and appliances arent going to be fried.

One year and is working very well.


Great price , no disappointments. This a quality unit. Rather large but after the first time using it got use to it. Works great as advertised. I used a quality bike cable lock to secure this to the RV park post ( for security reasons) this is a investment that I want to protect like my RV and electrical system ,etc. After doing much research about a surge protectors I realized that this would be valuable tool for protection from electronic /electrical problems saving me a ton of money and down time use of my RV. The unit constantly diagnosis the in coming power and has easy to understand led lights. I would highly recommend this product. etrailer prices were great, shipping is as always fast and packaged carefully as with all my purchases from them .


The Camco RV Power Defender has been great for me. Twice it has saved the electrical system in my motorhome so it has more than paid for itself. Contractors get in a hurry and wire outlets sometimes with reverse polarity, unaware to campsite owners and campers. This can cause a short in your RV and a shock potential when you think appliances are turned off and they still have a live current running through them. I would highly recommend this product .
E-Trailer sells these at an affordable price so there is no reason not to have one to protect your RV from costly repairs.


We have used this product now for 30 days in over a dozen different state parks and commercial RV parks. It has worked exactly as advertised. There have been no problems with the product.

This product gives us the peace of mind and reassurance that the electrical system, appliances and electronics in our camper are safe and protected from electrical spikes, surges, and out of range voltage variations.

A quality product and valuable insurance.


Just got back from my first camping trip. used the surge protector, worked great. Had to figure out how it worked in the beginning to turn it on I had a problem with my camper's outlet kicking off to many things plug in at the same time. Once I iron out the bugs, I had no more problems I would recommend this product Thank you


Bigger than I thought it would be...which I judge to be a plus, especially when dealing with electrical power types of things. Looks rugged. I plugged it into my backyard power supply (I keep my camper in my backyard) and everything lit up like it was supposed to. Of course the real test is "under fire" when it is needed in a bad power situation at a campground...which I hope never happens. Fast delivery. Packaging was a bit overkill, but ....


Very easy to use product. Have already put it to use on a camping trip. It shut down once during a voltage drop and restored power when voltage was restored. Well worth the money.

Still working great. I would recommend this product to anyone with a traveler trailer or RV.

Writing a great review for etrailer is so easy. Fast delivery. Great products. Fantastic prices. Everything I have purchased has been terrific. I am completely satisfied and I would gladly recommend etrailer to anyone. The camco rv power defender voltage monitor is just what I was looking for.


As always etrailer is top notch with great service. Have not had time to use the CAM55301 power defender yet ,but will be using for the next two weeks. Sure it will work fine. THANK ETRAILER YOU ARE ALL THE GREATEST!!!!!!


A power surge can happen anytime and you absolutely need to protect your substantial RV investment with the appropriate rated surge protector. I trust CAMCO products and etrailer is an excellent sourcing partner that I've relied on for years.


Works great and the best price and service. etrailer has great customer service so you always get the right parts.

No problems works great

Had another brand that I purchased from [camping retailer]. When it went dead after only 2 years (and only 8 camping trips) I called the manufacturer who said [camping retailer] had sold me a "sitting in the warehouse" old outdated product....which could not be fixed.
Very happy with my new Camco power protector. Will always shop at etrailer first.


This thing is HUGE !! Hope the power pole at the camp grounds will hold it. :) Looks like it is a very well made unit. I won"t know until spring when we start camping. Very friendly and fast service. Have bought from these people before and nothing but good to say. Will continue to in the future also. Thanks eTrailer and Ashley.


Received my product yesterday. I'm excited about using it to protect my 5th wheel camper. Ill be going out in a couple of weeks. Great transaction and quick delivery time (3 days.) Thanks George and the rest of your team for providing great products. I truly appreciate you taking care of us budget conscious consumers.


this was backordered and etrailer did me the favor of expediting delivery just as soon as they received the item because I needed it before departing on a trip with my trailer. THANKS!!! Great customer service!


Works very well. Has gone through several power service interruptions with no issues.
Glad we researched these for the camper. Even though it costs a bit more than others it certainly is worth it for a one time purchase to protect your investment.


Have used it to monitor and protect my Airstream from electrical surges, etc. at campgrounds and private residences across both the USA and Canada without any mishaps or issues. It’s easy to use and does what it’s supposed to at a reasonable cost!


This item has saved my bacon a couple of times at campsites which had problems with their electric service. It is cheap insurance.


Satisfied. Work as advertised.
It is
sturdy, well made, dropped it a few times and still works. Used it near freezing temperatures and kept working. It saved me from a bad campground electric setup once. Doesn't require special care or handling, I keep it in my truck bed.


Worth every penny!. Use it every time power is hooked to TV wether at rv park or at home on generator. Works everytime as it should


very satisfied ,my purchase is excellent quality, and does what is supposed to do lll

works well, very satisfied

received the 30amp. surge protecter 2 days after I ordered it , very fast service.
I went to the Chicago RV show and bought a new Rockwood Mini-lite , which I have not picked up yet from the dealer, because I have not got a call to say that it is in.
I plan on using the surge protecter on this new Rockwood , and I am sure it will do
the job it is intended to do . Thank you! You have great customer service!
