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.

I wanted to add a surge protector with the emergency shut down after my Hughes Autoformer and this worked great. I chose this one since it had plug ends and could be easily disconnected if there were ever to be a problem with a in my electical compartment.

I am so glad that I added this to our electrical compartment! Last fall we were staying at a place where the voltage ped low enough that even the Hughes Autoformer could not raise it up enough and the surge protector did its job and cut off the power that was dangerously low. As I mentioned in my original review, Im glad I went with this surge protector with the EPO!



by:

Love this protector, does exactly what it needs to do: PROTECT! This last summer we took a 4th month trip in our RV and ran into a lot of sketchy power posts, luckily this protector kept our RV safe. Heavy? Yes. Hard to store as the cable is vey stiff? Yes. Would I still use 100% of the time? YES!

Love this protector! We actually ran into a bad pedestal a few months ago and it caused some internal issue on our Watchdog not the module. I called customer service and they said no problem, covered by warranty, and they sent me OVERNIGHT an entirely brand new unit, with return label for my old one so they could inspect. New unit flawless. I would never buy any other unit!

@Neil Wow, that's great!

Works great. We have a 30 amp also but are upgrading the motorhome and needed a 50. Best on the market.

Still working great. No issues.

Obviously this high standard starts at the top and is embraced by every person associated with this business. Quality products and great customer experience always matters... Way to go!



by:

Just received and put in use. It was as advertised. The app was easy to setup and use. The box the unit came in is designed to also be used to stow and transport the unit, which is a nice bonus!

I look forward to great service from this unit while providing electrical protection for my 5th wheel RV!

Ive owned and used this surge protector for a year now. I have been extremely pleased with this product. It works as advertised. I have found the bluetooth information excellent and use the free app to monitor power levels. The app has been helpful for me to understand what branches of my RV 50-amp are tied to which leg of the service. This has helped me understand a good AC startup sequence. While parked at home I leave my power plugged in, I can monitor how much power my RV is using while it is in parked mode. I would HIGHLY recommend this accessory as a MUST HAVE for your RV!



by:

Been using even at home every day. No issues. Glad I have the protection

Plugged in 24-7 this past year and it’s protected us at the least three times we are aware of with no issues



by:

The Power Watchdog Surge Protector with Emergency Shutdown, did it job with I lost my neutral conductor on the incoming service for the power company. Took me a bit to figure out what was happening. It was showing an overvolt on one 120V leg and an undervolt on the other 120V leg. It would shutdown the power, and then the voltage would go back to normal. But as soon as I turn on anything that was 120V it shut off the power. Power company fixed their issue the next day and it started working normally. Would not hookup to shore power (home or away) without it.



by:

Peace of mind. Used for several months in past 18 months since we travel for periods of time. Easy to read display. The 50 amp can be used when plugged to 30 amp as well, so no need to buy two. Internal parts can be replaced if compromised by surge which is better than finding a new one.



by:

Easy to use. Love the fact you can replace the surge module. I bought an extra to have on hand (about $40). The surge protector being replaced by the Watchdog was a one and done. It was fried and no way to replace a module. Used a little over a year, so $300+ dollars down the drain.



by:

My Hughes Watchdog continues to work great. I love that:
(a) It goes beyond most surge protectors with line voltage monitoring and shutdown, to better protect my RV's electronics.
(b) The Bluetooth connection and app, so I can monitor electric loads plus see total power used.



by:

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 !



by:

It has worked flawlessly and the Bluetooth connection has made it easy to use.

Works great without a hitch! Glad I purchased it and like the ease in checking amperage per leg using app.



by:

Great product & competitive with [online]. Received product on scheduled delivery date. Bought it to replace my 7 yrs old surge protector . Like the fact that not only it protects from surge , it also protects from low voltage from RV park. Auto power shutdown ,Bluetooth compatible & able to see exactly whats going on with park power via phone app. Also like the fact that in event of major power surge the circuit board is owner replaceable vs sending it in for repair .

After 4 months stay @ RV park on Texas. Gulf coast unit performed as expected . Zero issues connecting to bluetooth app on phone. Liked the fact that a could get KW hrs per month via phone app. Great device



by:

The product works according to it's specs. E-trailer was a user friendly way to order the product!



by:

Great product with great tech features.



by:

This appears to be a robust surge and voltage protector. The customer service at eTrailer was super, as always. The Power Watchdog worked great when I connected it.

Still working great after a year. Peace of mind at the campground.



by:

Perfect product for RV!



by:

I like the product very much and would give it 5 stars if it could be viewed on more that one device!! I would like to see it on my phone AND iPad. However, right now you can only do one or the other. Also, with so many pedestals being “short”, the surge protector has to be “bent” and a lot of it is on the ground, especially where it’s plugged to the RV. I do like how you can see the amps and volts on my phone. It’s pricey and I hope it’s worth it!!



by:

Surge Protector is working, I guess. It's always lit up and the RV is plugged in most of the time for the past year. I don't know if there have been any electrical surges but it hasn't affected me if there were.



by:

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.

David

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.



by:

Etrailer shipped the same day as ordered. Very helpful. Etrailer is my "go to" for RV parts. Haven't installed product yet, but it is as advertised



by:

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.



by:

I wouldn’t use any other surge protector for my TT. It’s detected low voltage and open ground at different campgrounds and has done an outstanding job.



by:

First off, it is huge. Bought to protect our brand new travel trailer. Bought this model because of it's reputation and reviews and the fact that the protection modules can be replaced so you do not need to buy an entire new surge protector should you experience a fault. It is bright at night and the optional overlay screen certainly helps. This would be 5 stars all day long if it were WiFi enabled so that you could monitor your power when not at you rig/camp spot. Would buy again.
