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.

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.

Year later with the Watchdog and it is working like a charm. Very happy with this product. I bought an extra module in the event I had incident. Hasn’t been needed as of yet.

Just received the Watchdog Surge Protector yesterday afternoon. Plugged it in and seems to be working fine. Have yet to load the app but I anticipate no problem in doing so. Etrailer has been excellent in their communication and service.

After many months of usage, the Watchdog surge protector has been trouble free and twice saved us from problems due to low voltage. The app works great and helps us evaluate our electrical usage thus avoiding overuse. A little side benefit is that the dog face on it stays lit when there is power. My wife thinks it is a comforting sight to have our watchdog watching over us.

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!

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 !

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

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!

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

Delivered on time, package look like it was handled with care as the surge protector is in perfect condition. etrailer kept me informed from purchase to delivery. Very heavy duty looking product. I will do a follow up review when I have a chance to use the product this spring. etrailer sets the standard for excellence!

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.

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.

has worked as advertised!!! being able to monitor kw usage is a great plus when being charged by kw hour at certain rv parks.

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:

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:

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:

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.

Looks good. Can't wait to use it.

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



by:

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



by:

I haven't used this product yet. I bought it based on the reviews of others, its capabilities and features, and the reputation of the manufacturer.

I like that the surge module is user serviceable and can be replaced. I also like that the Bluetooth app will let me know what's going on with my power systems.

Physically it's heavy duty and built for the job. I don't like the idea that it's so bright and bought the shade from the manufacturer's website.
Until they include it in the kit (why don't they?) It would be a good idea for etrailer to offer the shade right as you are buying it because most people don't realize it's an option. I haven't seen it on any resellers site, yet. There are too many people who complain about light pollution AND I really don't want to advertise that I have a $300 device out in the open, at night.

I was torn between the portable unit and the hard-wired unit. Portable goes with me if I part ways with my RV, but it can be forgotten when packing up camp.
I can use the portable one to test the power pole before even backing in, but it is out in the open and is susceptible to theft.
Hughes sells a kit (you can buy your own parts at any box store for less) that you can use to mount an outlet and plug internally in your RV in between the external receptacle and the RV breaker by cutting the feed wire. If mounted in a convenient location then the best of both worlds can be had.


Overall I like this product and will buy it again.

First trip is in a few weeks, I'll really know then and if I change my mind I'll post an update.
