Protect your investment

If you aren't using a surge protector, you're taking a big risk. While spikes caused by lightning can damage your electrical system and appliances, there are common electrical issues that can be just as dangerous. Choosing a surge protector with advanced features will help you protect your RV.


Smart Surge Protection

Electrical problems are not uncommon at campgrounds, especially ones where wiring was originally installed decades ago. When a campground is full on a hot day and everyone is running their air conditioners, low voltage may cause a brown-out situation and damage your RV appliances. On the flip side, faulty transmission, bad wiring, or spikes caused by other RVers connecting to a shared line can all lead to voltage issues that may not be significant enough to trip a basic surge protector.


Power Watchdog surge protectors with Emergency Power Off are equipped with computers that monitor voltage and disconnect when voltage is at risky levels. Plus, they automatically reconnect power when power returns to normal. This keeps your RV safe from problems caused by low voltage like motors overheating in fans and air conditioners.


In the event of a major spike, you can replace the surge protection module itself rather than the entire unit. The modules are plugged in without soldering, so you don't need to be an expert electrician to make an easy repair. In fact, the only tool you need is a screwdriver.


Information at Hand

The Power WatchDog smartphone app

The Power Watchdog app lets you connect to your surge protector via Bluetooth. You can monitor your energy usage, making it easy to diagnose any ongoing energy issues you may be experiencing. When voltage increases or decreases to risky levels, you will be notified right away. You can also reset your surge protector without stepping outside.

Video Transcript for Review of Hughes Autoformers RV Surge Protectors - 30 Amp Hardwired RV Surge Protector - HU77FR

Hi there. I'm Michael with etrailer.com. Today, we're going to take a quick look at this Power Watchdog, hardwired 30 AMP surge protector with Bluetooth and emergency shutoff. This is going to hardwire into your RV's power system. It's going to protect your RV from power spikes from your shore power hookup. This will offer 2,400 joules of surge protection.

So if the voltage drops below 104 or rises above 132 the smart circuit analyzer is going to shut down the power to your RV so that you're not going to have to worry about any damaging currents coming through. This will turn back on the power after it is, had a safe range for 90 seconds. So it's going to do a good job of protecting all of your electronics in your RV. This does have a hardwired design, so now just going to have to install it once and then you'll be able to hook up your system like normal. Once you get to your campsite, we'll just plug into the sharp power or shore power and it will automatically start working.

It's got about a four second delay but then you'll hear an audible click to let you know that it's on this dog face here, will light up to let you know if everything's going right. So it will wind up white, if the park power pedestal is providing a nice steady source of power. If this lights up red or that means it's not providing steady power there should be an error code that will light up here on this little digital display here that will give you an error code. That lines up with the error code list here on the side. This is gonna check for open ground, open neutral, open circuit, reverse polarity and miswired connections.

So if any of those come up they'll know what's wrong. You'll be able to correct it or what the camp site managers know. This also has the Bluetooth connection capability So very simple to download that free app onto your iOS or Android device. You'll scan the a QR code here to get it connected. And then you'll be able to connect your phone to monitor your volts, amps, and watts as well as your kilowatt hour usage.

And then it will also send you notifications. If there is any problems, if the voltage is outside the acceptable range we'll also let you customize the alerts for or threshold. So if anything is more than you want, if you find out you're using a lot more power than you intended to or something along those lines, you can set up those alerts. They're very easy to get all that set up so that you can monitor and just open up the app and see how much you're using from time to time and then make sure that everything is coming in clean and at the right amount of power. This is gonna store right into your compartment, so it's not going to have to worry about weather or anything like that. It's going to be nice and protected. It's not going to take any extra steps to get it hooked up when you, once you get to the camp site. So it's going to be very easy to use. As far as our dimensions go, this is right about, I mean it's call it six inches wide from our outer points here. It's right about six inches. Then our thickness right about four inches. And then our height, I'm going to say right at 10 inches, sorry, 10 and a half inches tall. So make sure that that's going to fit for your compartment. You're also going to need room for your wiring. Obviously that's not gonna come out at a perfectly straight or 90 degree angle. You'll probably need a little bit of a loop on either side. So to make sure that you've got enough room wherever it is going to put this to store it so that you can get it all wired up properly but should be a really nice, easy project for you. This does have a a unit inside of it that is going to help with that surge. If you we're to get a really big surge and you we're to blow that card, you can take this box apart just simple screws there, open it up and you can replace that card rather than having to replace the whole unit. So, nice little option there. If you we're to ever encounter a really large surge that would blow that card, it is replaceable for you. So overall, this is a really nice option. There is a portable option. That's very similar. It's just got your connection so that you can just plug it into your wiring from your RV and then plug it into the shore power. If you want something like that. If you might, maybe if you're moving from RV to RV but this is a nice hardwired option so that you can just put it in one time and forget about it and just plug it into your shore power like normal. So if you are looking for a 30 amp option this is going to be the right pick for you. We also have 50 amp options available and as well as a lot of other RV supplies. So if this isn't what you're looking for I'm sure we have another option for you. So it's going to complete our look for today. Again, I'm Michael with etrailer.com. Thanks for watching..

Power Watchdog Surge Protector with Bluetooth and Emergency Shut Down - Hardwired - 30 Amp - HU77FR

Average Customer Rating:  4.8 out of 5 stars   (651 Customer Reviews)

Get on-board protection from power surges and low voltage with this hardwired surge protector. Disconnects power when voltage is low to keep your appliances safe. Monitor your connection and diagnose problems with your smartphone.

by:

Wired up and functioning properly. Word of warning choose your location wisely, it has a slight hum when operating. I had to do some soundproofing in addition to the installation.




by:

This surge protector hums very loudly, you could hear it inside the trailer as well as outside. I had to remove it since it made sleeping in the trailer impossible. Neither etrailer nor the manufacturer would replace it or give me a refund.


Comments
I have gotten information back from the manufacturer and they say that typically, you should not hear it from more than 5-6 feet from it, or at least it not being loud at that point. If the humming is too loud past that 5-6 foot radius, this item does have a lifetime limited warranty.

Since installing this thing I’m lucky if I can run my A/C and microwave at the same time because of the damn emergency shutdown feature. Would not recommend or purchase again.


Comments
something to keep in mind is that you would need to be wary of thing like a water heater or a battery charger could be kicking on therefore adding to the amp draw. Just double checking in keeping the total amp draw in mind is key. If those extra things kick on at the same time, that would cause it to use the emergency shutdown.

Just love this onboard version of the Watchdog. No more worrying about my expensive piece of equipment hanging out in the campground, lit up for all to see. Also has protected me a few times from overloading and from a faulty ground at one camp.




by:

Installed on by cargo trailer conversion. The cover seems a little flimsy but it is comparable to what was on my previous factory travel trailer.




by:

The unit works as advertised allowing me to see power usage on individual systems. Being able to see input voltage is good and so far, no huge power spikes.




by:

The Watchdog has taken the guess work out of hooking my RV.




by:

Been working great let’s me know if I am close to a over load and if park power in correct.




by:

I really like this unit. All the other reviews are correct: Yes its huge, yes the bulldog logo is super bright. I installed it in an enclosed area on my trailer (Coachman Apex Nano 194BHS) in the water heater compartment (above/away from any possible water leaks), so the size and brightness are not an issue for me.

The Bluetooth range is really good (maybe too good, it reaches halfway thru the house when parked outside). The app is also pretty cool, because you can use it like a Kill-a-Watt by going around the camper turning things on/off (pro-tip: use the circuit breakers for most accurate readings).

Really appreciate not worrying about this expensive gear getting stolen, or forgetting it during setup, etc. Protected from day 1.




by:

Excellent product that has likely paid for itself several times. Would purchase again




by:

Easy installation




by:

Fast shipping! Easy install on my keystone passport. So far so good. I like this surge protector because it is hard wired inside the rv and eliminates theft of the unit.

promp service thanks

Review from a similar Power Watchdog Surge in RV Surge Protectors


This product saved our toyhauler from going up in smoke ! While Glamping at our friends ranch in Colorado in June of '22 , Lightning struck their main power pole supplying power to the 40 acer property . Our RV was about an eighth of a mile from from the pole . The BOOM and SIZZLE sounds were like none other ! Scared the shizzle out of us ! After the power company restored the service , hit the breaker and the power was back on , no issues . Thank You to our Watchdog !

Review from a similar Power Watchdog Surge in RV Surge Protectors


Well seeing as how it was just purchased ,yes 5 stars, great service , easy to hook up and works great with the Bluetooth with very good range.


Comments
After a year my empower Watchdog Surge Protector is still fantabulous, so much so that I purchased another for the 5th wheel we live in when not traveling with our super c. I can monitor either one from inside the 5th wheel while at home.

Review from a similar Power Watchdog Surge in RV Surge Protectors


Rating is for etrailer, not the Watchdog as I won't be using till January. Communication was beyond a 5 star rating. Never have I had the communication I experienced with this purchase from placing the order to delivery. The Watchdog was priced competively, box undamaged upon delivery, now just waiting to travel to our snowbird destination so I can start using it.


Comments
Excellent product. Never felt the need for one til I started traveling. Was some pretty sketchy power poles out there. The app was easy to pair, nice to have the information at my fingertip. The extreme length of the Watchdog hasn’t been an issue, nor has the amount of light emitted from the unit. I also bought the replaceable surge protector part just in case, but haven’t needed it. Overall this was a wise investment!

Pretty Cool Stuff!
Plugged it in, waiting
for the face to light up, plugged in the camper. Awesome! Everything works, the app works, I can monitor my electrical voltage, current, anywhere. It's pretty cool.

Review from a similar Power Watchdog Surge in RV Surge Protectors


We used the surge protector for approximately 3 months over the past year. Having the ability to confirm the electricity provided by the campground will not damage my onboard equipment is priceless. The power watchdog is the first thing that gets hooked up when we stop, then I turn on the breaker and look to see if it lights up white for normal conditions or red for a faulty condition. If it is red I request another spot.

You people fit that bill for all, sorry to say that is not true for some today, Take Care Have a Great Day, Best to All,

Hello
I like that the app allows me
to keep an eye on the voltage of each line coming to my rig along with the amps.
The installation was easy too.

Review from a similar Power Watchdog Surge in RV Surge Protectors


So far I love everything about this device. It is a bit hefty. But I suspect it is engineered for performance vs.compactness. The app is nice in that I can get an idea how much current any appliance draws when it turns on. I like the bright light because it illuminates the utility side of my trailer if I need to get to something after sundown. If it ever becomes obtrusive, I will just hang a black trash bag over the power box. A 10 dollar cable lock from wallys mart seems to solve any potential theft problem. But you could also put a small padlock on the hasp that seems to be on every power box. (the plug is actually engineered so that you can fully close the door)
i will change my tune if it smokes in the next year. But so far it is the best $xx.xx I’ve thrown at my rv.

Review from a similar Power Watchdog Surge in RV Surge Protectors


We have been using the Watchdog for the better half of the season since we had to replace our power cable. It had a burnt end due to a poor hookup at a campsite. Nowwe can test our hookup before we connect our trailer. There is also an app that helps monitor the connection. The best thing about the Watchdog is that the replaceable surge protector.




by:

Review from a similar Power Watchdog Surge in RV Surge Protectors


I purchased this surge protector after reading other reviews and it has worked flawlessly. Great peace of mind for sure. Fortunately the camp grounds we have stayed at so far were well maintained and had newer style power pedestals with no issues. Also works as a great night light!




by:

Review from a similar Power Watchdog Surge in RV Surge Protectors


This surge protector does the job very well. Plus, the Watchdog is an easy form of alert. Pleased to find it on eTrailer, good price, fast shipping.
