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.

by:
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.

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.

by:
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.

by:
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.

Pros:
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.

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

Tip:
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.
by:
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.

by:
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.
by:
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.

by:
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.
by:
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.
by:
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.
by:
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.
by:
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.
by:
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.
by:
Purchased this after first purchasing a surge protector that only protected against surge not low voltage.
Works well at this time!
by:
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,
by:
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.
by:
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.
by:
Extremely fast service, product came packaged excellently and is just what I needed, would highly recommend etrailer.
by:
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

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

Did a lot of research on this product. Will work well with my new RV. Solid production and craftmanship. Worth the costs.

Do you have a question about this RV Surge Protector?
  • Troubleshooting Camco 50A Power Defender Not Allowing Power to Go Through
    I reached out to my contact at Camco who said that if you didn't give the Camco RV Power Defender # CAM55306 2 minutes to run through diagnostics after plugging it into the power source then that would cause the lights to act like what you described. If you plug it in and let it sit for at least 2 minutes it should then either give you one of the different light indicators and/or will work properly. If this doesn't solve your problem let me know and I can help you troubleshoot further.

  • Troubleshooting Open Neutral Reading Only When Air Conditioner Is Running
    The Camco RV Power Defender Voltage Protector - 50 Amp # CAM55306 is reading correct when you are in basic use. So we know the shore power is not the issue. We know that AC units do pull a lot of power, so the momentary open neutral wouldn't be a concern but if it says that way the entire time you are running your AC, I would have the wiring looked at to confirm you are safe in its use.

  • Troubleshooting Sidewinder Pin Box that Angles When Backed Up
    If when you back your trailer up straight the Sidewinder arm turns at a slight angle then you have a wedge issue. Since you have a B and W Patriot the correct wedge is the part # SWW-06 which you'd want to verify is the one you have and is installed properly. Make sure it's facing the correct direction and that all of the install bolts are torqued down to spec. Could you send a picture of the jaws of your hitch and the wedge as well possibly?

  • Recommended Surge Protector for 50 Amp 5th Wheel Trailer Connection to Shore Power
    For your 50 amp system, you will want the Camco RV Power Defender Voltage Monitor - 50 Amp # CAM55306. This voltage monitor disconnects when dangerous voltage levels are detected and then reconnects when it stabilizes. This is much better than the cheap surge protectors that need replacing and are only good for one surge and then leave you disconnected or vulnerable. You won't need a different surge protector for your 50 amp RV wiring. For sites that won't have a 50 amp service, I recommend...

  • What is the Difference Between a Power Analyzer and a Surge Protector 50 Amp Adapter
    An analyzer such as # CAM55313 has diagnostic lights to indicate faults so that you can avoid damage to your RV. This model also offers surge protection. A model that offers only surge protection would not have any diagnostics. But some have both. There is also the Power Defender # CAM55306 that takes surge protection a step further by having the ability to detect too much AND too little power and disconnect and reconnected as needed.

  • Camco Power Defender Showing Open Neutral When Plugged Into RV
    If you are plugging the Camco RV Power Defender Voltage Protector # CAM55306 directly to the shore power outlet and only getting the "Open Neutral" fault when plugging in the RV then there is an issue either with the outlet itself or your RV cord. The reason the error is only showing when plugging in the RV is because it will only detect it when power is being sent back to the RV/trailer. It is basically needing a bigger load placed on the circuit to identify this fault. I recommend inspecting...

  • Recommended Adapter and Surge Protector for 50 Amp System to 30 Amp Shore Power
    With your 50 amp camper system, I recommend using the Power Grip RV Power Maximizer - 50 Amp Female to 15 Amp Male and 30 Amp Male # CAM55025 to allow you to plug into 30 amp power supplies. Then you will use a surge protector like # CAM55306 for multiple surge protection or # CAM55313 for single time surge protection. Many people use the Camco Power Grip Cable with Lock # CAM44290 to protect their investment. Unless you convert your entire system to 30 amp, I don't recommend using a...

  • Connecting 50 Amp RV to 15 Amp Outlet At Storage Facility for Keeping Batteries Charged
    For your particular setup, starting at the RV's 50 amp plug, I recommend the Camco RV 50 Amp Voltage Protector # CAM55306 followed by a power adapter cord like the Mighty Cord # A10-1550D90VP that will plug into the surge protector and give you a 15 amp male plug on the other end. Then from there you will just need an extension cord like the 25 foot # A10-2514E that will reach to the shore power hookup at the storage facility. This extension uses 14 gauge wire so that would be my recommendation...

  • Connecting 50 Amp Electrical of 2019 Thor Challenger to Regular Electric Outlet for Storage Power
    From your outlet, you will first use the Mighty Cord Dogbone RV Power Cord Adapter - 50 Amp Female to 15 Amp Male - 12" # A10-1550VP or the Power Grip RV Power Maximizer # CAM55025 and then the circuit protector # CAM55306 to protect your RV electrical system followed by the 50 amp power cable to your RV. There is nothing you need to do differently inside your RV as it is already designed for your refrigerator and other appliances to function.

  • Troubleshooting Low Power from Shore to Transfer Switch
    It sounds like you have a short in your Power Cord wiring as there isn't anything between the power cord and the Go Power Transfer Switch # 34270278 as they are directly wired. I've attached a video of the Go Power Transfer Switch - Quick Connect - 30 Amp # 342GPTS which shows these connections. If you don't use and in-line circuit breaker like # CAM55306 then there has to be an issue with the wiring or the ground on the transfer switch itself.

  • Differences Between Camco Circuit Analyzers and Power Defenders
    You are correct. The 30 Camco RV Power Defender Voltage Protector # CAM55301 is like a circuit breaker and automatically resets if there's a surge whereas the 50 amp Circuit Analyzer part # CAM55313 is like a fuse and it only can handle one surge. For a 50 amp breaker style you'd need the part # CAM55306.

  • Joules of Surge Protection for the Camco Voltage Defender
    I spoke to my contact at Camco and he informed me that the Camco RV Power Defender Voltage Analyzer # CAM55310 that you referenced offers 1,050 joules of surge protection but it's primary function is to determine if a power outlet/pedestal is wired correctly. For more voltage protection you may be more interested in the # CAM55301 that offers 2,450 joules of protection or the part # CAM55306 that provides 3,850 joules of protection. Review videos for all three products are attached.

  • Comparison of Camco Circuit Analyzers and Voltage Protectors
    Camco Power Defender voltage protectors, parts # CAM55301 and # CAM55306, have a bit more protection than the circuit analyzers, parts # CAM55310, # CAM55312, and # CAM55313. Both the analyzers and protectors have diagnostic lights for faults but beyond that the analyzers are just surge protectors. The voltage protectors go a little further by detecting the voltage and shutting off if the voltage level falls below 102V or goes over 132V. The voltage protectors also reset themselves...

  • Comparing the Camco RV Power Defender Circuit Analyzer and Voltage Protector
    The Camco RV Power Defender Circuit Analyzer part # CAM55313 and Camco RV Power Defender Voltage Protector part # CAM55306 are similar in that they both work to protect the trailer from power surges and have diagnostic lights to help with troubleshooting. However, the Voltage Protector goes a bit beyond this as the voltage detection system is much more sophisticated sensing both high and low voltages in addition to surges. The Circuit Analyzer can only detects power surges, not high and...

  • Surge Protector When Using Adapter to Connect 50 Amp Camper to 30 Amp Service
    In order to plug a 50 amp camper into a 30 amp hookup at a campsite you will indeed need an adapter, for which the Mighty Cord # A10-3050FHVP will work perfectly. With this particular setup you would still want to use a 50 amp surge protector like # CAM55313 for one time surge protection or # CAM55306 that will automatically reset and can be used again and again. Since your camper is rated for 50 amps you just have to protect against surges over this, so you wouldn't need to lower the...

  • Recommended RV Power Monitor/Defender for 50-Amp Service
    No, instead you will want to use the 50-amp version of the Camco Power Defender, which is their part # CAM55313. This provides the same circuit analyzer and voltage monitoring functions along with surge suppression but in the 50-amp capacity you need. A similar but better option is their RV Power Defender Voltage Monitor # CAM55306 which provides those functions but adds the ability to automatically disconnect when dangerous incoming voltage levels are detected. It will automatically...

  • Can 50 Amp Surge Protector be Used with 30 Amp Power Source
    A 50 amp surge protector like Camco RV Analyzer 50 amp # CAM55306 won't do anything unless you exceed the 50 amp rating of the product. If you need surge protection for 30 amp it won't stop a surge relative to a 30 amp setup. It basically would let anything through till it exceeds 50 amps.

  • Does 50 Amp RV Need 30 Amp or 50 Amp Circuit Protection When Using 30 Amp Service
    Surge protectors are designed to protect the RV's circuits and accessories so even if you were using a 30 amp service your RV would be safe up to 50 amps so you'd want to use a 50 amp surge protector like the # CAM55306 which automatically disconnects when there's a dangerous voltage level and reconnects when voltage stabilizes.

  • Surge Protectors for 30 Amp and 50 Amp Power Sources for RV
    I wish there was a circuit protector that could cover both amperage ratings but you'd have to have a 30 amp protector like the part # CAM55301 or the # CAM55306 for a 50 amp setup. For a 30 amp female to 50 amp male adapter you'd want # A10-5030FHVP.

    You want circuit protection to protect your RV's wiring which is rated for 50 amp....so you'd want to go with 50 amp circuit protection. For that we have the part # CAM55306 which automatically resets or the part # CAM55313 which is more like a fuse and is internally damaged and needs to be replaced in the event of a surge. To adapt this to a 30 amp power source you'd want the part # A10-3050FHVP and you'd be set.
