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..

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.

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.

Review from a similar Power Watchdog Surge in RV Surge Protectors


Excellent packaging. All necessary parts included. Easy installation (depending on your situation). Electrical connections couldn’t be easier. I recommend a no-ox type grease to prevent corrosion from moisture and dissimilar metals. Unit worked perfectly. WiFi to phone works great and is very convenient. Mine is mounted in the basement of a 5th wheel so can’t see it readily. Highly recommend the quality device.

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.

I ordered the Power Watchdog at 1019 hours on 7/24/21 from etrailer and they shipped it the same day and I was able to track the package via tracking information which I also received from etrailer awesome service. I received the package quickly and in great condition. The price was also very competitive. What's not to like. I will order more items from etrailer in the future.

Review from a similar Power Watchdog Surge in RV Surge Protectors


Hooked up my watchdog surge protector with blue tooth today. followed directions supplied and blue tooth connection was a snap. was able to tell current draw for each of the appliances in my camper which makes power management much easier. Like the display with voltage, amps and kilowatts used which is resettable. What really sold me was the blue tooth to my phone so you don't have to buy a separate remote meter. Blue tooth on my iPhone was good for over 50 feet. After I ran it off my house power I tested it on my inverter generator. Made a floating ground plug for my generator and everything worked great. Looking forward to camping without the worry of guessing about power quality where I hook up.

Review from a similar Power Watchdog Surge in RV Surge Protectors


etrailer good product good price. I knocked off one star because the dog face light is way too bright and apparently can't be adjusted or turned off(might be better if it just came on with a problem?). i appreciate the idea of an indicator light but it certainly doesn't need to advertise or light up the campsite as well as indicate status, especially with the potential for theft. As to function it seems to work... it did for the few tests i ran and the bluetooth app/connection (though minimal in it's info) worked well, was an easy setup and much appreciated.

Review from a similar Power Watchdog Surge in RV Surge Protectors


Love the Watch Dog! I also installed the AutoFormer and mounting hardware. Easy install for most DIYers and hughes theirselves have great customer service. The only issue is, before you hard wire and mount the Watch Dog surge protector, get the serial number off the back of the unit to register the unit for warranty. Yep, learn from others!

Review from a similar Power Watchdog Surge in RV Surge Protectors


This thing is MASSIVE! It is the big dog on the block or the campsite! It works great and protects all the fragile components they put in campers today. I would much rather replace a 200$ surge protector then replace the 200-400$ Or more circuit boards on the AC unit the fridge, or other electronics that are installed in my camper.

Review from a similar Power Watchdog Surge in RV Surge Protectors


Works right out of the box as described. App is easy to set up and sync. App works as described and is easy to use. It's nice that the surge board can be replaced for $xx.xx after a few surges instead of having to buy a new protector. I don't particularly care for the bright light of the dog face. It's not terrible, but I'd like to turn it off if I could. I also would have liked to have seen some weather protection over the female plug.

Review from a similar Power Watchdog Surge in RV Surge Protectors


We haven’t used it yet but it came on time! Communication with etrailer staff is wonderful! I’m sure it will work great! We wanted a surge protector which was for more than one use. We stayed at an older campground, one we frequent often. There was a power surge there & it wiped out the furnace & AC! Now we will be protected!

Review from a similar Power Watchdog Surge in RV Surge Protectors


This surge protector arrived earlier then was indicated by two weeks! I was very pleasantly surprised when this company had an employee reach out to me to offer and alternative device they noted was in stock. As I was committed to owning a 50 amp protector (instead of the 30 am protector offered) I let them know I was going to stick with my original order and wait for the surge protector I believed was best for my fifth wheel. The employee let me know the status of my order at every stage of my order and I was really pleased to have my new surge protector weeks ahead of the communicated delivery date. This company really went the extra mile and I saved over [XX] dollars on what I would have paid on [online vendor] for the exact same device. I will be shopping here again!

Review from a similar Power Watchdog Surge in RV Surge Protectors


I have bought many of these and they are fantastic. This is the only one to buy, THIS IS NO JOKE these are the BEST and cost less than the others, but the best thing is that they are rebuild able by you on site if they have taken a hit and saved your trailer from a costly repair. It also shuts down, if the voltage goes to low or to high which can damage your electrical devices. It will also let you know what is going on when it shuts down. We recommend Hughes to everyone.

Easy to install, but it’s a strange feeling cutting the power cord. Lost about 8 inches of total length based on mounting location and strain relievers. Bluetooth is a nice addition. Hope it never triggers, but it’s there if needed.

Really like that the Surge board can be switched out. My brother was not so lucky after camping in a private campground this year. By the time they smelled the smoke the Surge protector they had was already beginning to melt.

Ask the Experts about this Hughes Autoformers RV Surge Protectors

  • Does 50 Amp Surge Protector Offer More Protection than 30 Amp Surge Protector?
    The Hughes Autoformers are certainly the deluxe of all the power protection products. On top of all the low-voltage, high-voltage, Mis-wiring protections they offer - the hardwired units offer protection from thieves! This unit goes inside your coach instead of hanging from the outdoor post. However, buying a 50-amp unit offers no more protection than a 30-amp unit IF your coach or trailer only connects to 30-amps. If your camper only plugs into 30 amp then you should purchase the...
