OUTSTANDING! Don't waste your time with thise cheap power strips. It gives me the best peace of mind when connecting at a RV park. A must have.


Purchased this after first purchasing a surge protector that only protected against surge not low voltage.
Works well at this time!


So far, so good. Took about a minute to run through it's diagnostics, then all good to go.
Bought this because the last army corp campground we stayed at, had problems with the power going on and off.
Will feel a little more protected now.

Works great, and with the 30 amp adapter, can use it with 30 or 50.

The CAM55306 looks well made. Received the item in a couple days plugged it in and in a couple minutes camper powered up. Every thing's working fine. While away from the camper had power outage everything came back on no problems. One less thing to worry about. Thanks for a great product at a better price than competition.


Great product for RV protection. Gives you a piece of mind knowing that your rv has this electrical protection


Yes I would purchase again. It's comforting knowing I don't have to worry about surges to my RV. For me it's no problem but it could be a little heavy and cumbersome for some older folks. I devised my own cable locking system to the elect. box just incase Im in a park where I don't trust everyone. This is such a nice item to have someone else may want it more than me.

Still working great, would purchase again.

Put the product to work the weekend after receiving it in the mail from etrailer. Worked immediately to protect our electrical system. Only saw the green light during our stay in the RV resort but having it gives me peace of mind.

Still working fine protecting our electrical system. Also have found the loops on the handles make it easy to cable lock my power cord and the voltage protector to the RV site power box.

The Camco RV Power defender has worked well for me over the last year of ownership and full-time RVing. On the exterior: generally it’s held up well, but has shown some wear.

It has caught many low voltage situations where power has been unsteady.
It has brought a lot of piece of mind knowing the electrical system is protected.

Slow to boot up on first plug in or after power issue detection.
Much larger than the competition.

Since the unit is so large often it will be on the ground and not hanging vertical. Technically, it’s only water resistant if hanging vertically. Keep out of puddles and use a trash bag in rainy conditions to cover the unit in this situation.


I have had this for about a year now. I RV quite often and this surge protector is awesome. I have a 42' 5th wheel 2019 and as you know loaded with electronics. We have had a few occasions where the protector absolutely saved us. When there is an issue it powers down then reboots slowly to prevent a surge. Highly recommend it.


i have not had the chance to use the product yet but etrailer got it to me very quick. 2 days. very easy web site to order from. Great customer service with followup emails letting me know it shipped and follow up for product satisfaction.

I have had no issues with our surge protector. we leave our camper plugged up full time and to my knowledge we have not had any issues with power. we are not in the camper full time but use it on most weekends.

Excellent product. Simple to use. Very quickly runs through voltage checks. Provides peace of mind that camper electronics will not be fried.

Product is trouble free with no issues. It was tested when power went out during a thunder storm. It worked as designed.

Well made. Gives me peace of mind.

Very Happy after a year of daily use!

Camco RV Power Defender Voltage Protector gives me peace of mind when we are traveling the country and etrailer is the BEST online company to do business with.


This is my 4th or 5th experience with etrailer and they have yet to disappoint. Not much to evaluate on the 50 amp surge protector. I did find there is a delay while it searches for faults. Seemed to be about 2 minutes before the air came on in the motor home but its not even an issue. Works fine though I haven't had a surge so ill assume all is well.


So far so good you should always protect your RV from power surges but this takes it a step further so you can monitor your power. We have had power pedistial problems at 2 RV parks in the last year it's good to know before you connect your RV and possibly cause any damage.


After almost burning out the wiring in my new RV at a camp site. I purchased this item and feel very comfortable in the protection it provides me.


The only place I have used this product is at my home. I plugged it into my 50 amp service that I had run to check the circuit as well as to see if it worked. After a few seconds it showed all was good. We are fixing to go on back to back camping trips in a couple of weeks so I will give it a good work out then.


I used this product for 20 weeks last year without any issues - I made connection is some 40 different sites. I feel well protected with this product

Yes - the device is working well - just finished a 4 week trip visiting 4 different campgrounds. The only issue is waiting after you plug it in for it to do its necessary checks before giving the green light. I feel good with the protection
Mr A - 04/24/2019


I’ve been using this product for the past 2 months in various campgrounds and RV parks. I like that it analyzes the incoming current before connecting the RV and I have confidence that my electrical system protected.


I knew I had to have a surge protector. The functions on this covered all my wants. I've only used it at the house so far. Time will tell on the actual quality.
It seems well made.


Great unit two mouth after purchase at campground one power leg went down to the campground and it shut down the camper. Which save the A/c and other equipment. Help to in joy camping when you don’t know when a power problem may come up.


I have had refrigerator trouble I was told it was voltage surges shutting down my refrigerator. that's why I bought the defender . usually the plugins are not always wired correctly at the parks,


Yes, it took about 140 seconds to provide power to the Motorhome after the diagnostic routine. Great service from Danny T. Thank you,



I haven't had a chance to use this yet but it seems to be a well built product. I like the large pull handles to assist in unplugging.


Extremely fast service, product came packaged excellently and is just what I needed, would highly recommend etrailer.
