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.

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.


We love the Watchdog! No problems and great protection.


with many campgrounds still struggling with maintenance of their sites this surge protector gives more than basic protection to our campers electrical system


First trip using Watchdog. Appears to be working as advertised. Very easy setup. Love the smartphone compatibility.

After a year, still very happy with this surge protector. The app works great and its nice to be able to see just how much power the trailer is drawing.

Really happy with this protection. When accidentally overloading a circuit a few times (turning on a portable heater and coffee maker at the same time), no need to crawl down and reset the main breaker on my electrical panel.
Power Watchdog auto tripped the surge and easily restored the circuit using the app reset (now with the heater off and coffee brewing).
I also use a medium size chain and lock, along with a grey plastic grocery bag to cover and keep it from drawing attention to itself while camping.


I have been very happy with my 30A Bluetooth Power Watchdog. We typically camp 9 weekends and one 2-3 week trip each year. We stay a many different campgrounds. Since we bought this I have had it protect us from a few overcurrent situations due to low shore power voltage. The ability to use my phone to troubleshoot is great.

There are only two improvements I would reccomend. First, tone down the LED brightness for the status. The bright white dig face is a bit much. I cover the power pedestal with a co tractor grade trash bag to solve this. Second, I find the leads a bit long. The issue here is the connection to the power cord oftem sits on the ground. I end up using shock cords to hold the box up higher on the pedestal.

Overall, I am very pleased with it.


Watchdog has performed flawlessly over the first year. It is very user friendly and the app is really nice to have. We have used the app to find out actual amps a device uses by plugging it in and watching the app to see how much amps increases by. For example, our camper is 30amp. With AC running we might be using 18amps and then plug in a cooking skillet and amps jump to 28. This we know the skillet requires 10am pjs. This makes it easy to manage our usage. The Watchdog has saved our camper from both low voltage in campgrounds and power surges. As well as times when we tried to run the AC and microwave at the same time. We also appreciate that the device will reset itself after we lower amps to below 30 without us having to walk out to power post and reset. We like the sound when it kicks in and the light assures us it’s working or if there is a problem at the power pole. We feel very good that Watchdog is helping protect our investment.


This has helped us multiple times in the past year with electrical issues in various parks, due to storms, outages and the campgrounds own electrical problems. We couldn’t be happier with our watchdog and are sure it has saved us problems in our camper several times!


Have been using the watchdog surge protector for a year now and am very happy with it. Also love the blutooth phone app so I can easily see what status is or what Just Happened. couple times we had line events and the Watchdog caught it before there was an issue to the RV and reset was a simple app command. did not have to leave the RV.


Works as promised. Annoying feature is that over current trips at a few tenths of an amp over 30amps. 30 amp Circuit breakers normally trip at about 35 amps. So we get over current shutdown every few days from the power watchdog


The power watchdog is a fantastic piece of equipment that everyone should own. It provides piece of mind in rv electrical system malfunctions. A cheap investment to prevent thousands of $ in potential electrical system damages.


The surge protector works great Except on portable generators.
Portable generators have an open ground so the surge protector turns off and will not work.


Recent purchase. Installed/connected to motorhome in storage for the winter. We often have power outages in our rural area and believe this will prove to be a beneficial item to protect the motorhome's circuitry.


I am so happy with this surge protector! Just this morning it prevented a surge at a campground that I am workamping at! Great peace of mind cuz you just never know when/if it's going to happen!


This was the best purchase we have made in years. We've been camphosting for 9 years and heard many horror stories that occurred without a surge protector. Love the features and replacement parts abilities.


Very pleased with the Power Watchdog. Would definitely recommend it. Has shut down twice because of electrical issues. Both times reset, and all good.


Finally got the surge protector.
It was
lost for a while at the campground office since the address was not printed in full on the ups label, part which included the c/o and the camp side was not the label.
Can you please add additional address line to your ordering form, that this will not happen again in the future?

Otherwise thank you for a great service and good product as always

I will let customer service know you would like to add information to your account.
-- Etrailer Expert Heather A - 02/23/2022


Works as advertised. I’ve used a couple of times since purchasing and have had no problems. Having the app on my iPhone is very helpful knowing the amount of amps being used versus what’s available. Great product


Great product. A bit bulky but well worth it because of security it offers.


I have yet to take it camping but did set it up and tested in garage. 4stars because I need more experience with it. I replaced an old unit (different brand) with this one. It Is big but I like the bluetooth feature for monitoring and replaceable surge module feature.
I will give 5 stars to etrailer customer service. Before I received this order I found it cheaper on line I sent an email to etrailer and got an immediate refund. Great customer service. Thanks


Performs as described. App is easy to load and use.

Works like it should. If I try to start up too many appliances that will exceed the 30 amp service the watchdog will cut it off and not allow it on until I reset it. That lets me know I’m overloading the system by having that appliance on while the other appliances are running. AC and electric hot water heater on and turning the microwave on does it every time.
Joseph - 08/08/2022


Works great. I can see my kw on the app and reset to zero when needed.


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.


Works great and relieved to have this safety feature on our new camper. Was shipped very quickly and came 2 days before stated.


Nice unit works great and was delivered a day early
