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.
Voltage Boosting
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.
Voltage boosters respond by automatically boosting voltage when low levels are detected. As voltage drops, electrical circuits respond by increasing amps. The booster converts the increased amps into volts to keep your connection strong. If volts drop below a usable threshold, it automatically cuts off power.

Ratings & Reviews
It is nice to have an extra level of protection for our coach. So far has worked as described. Would appreciate a slightly longer cord for resorts with higher plugs.
So far, it's great. I can monitor the voltage to my RV while I'm away. This is a great feature. The voltage boost also works great. It's worth the extra money. The only thing I worry about with this Watchdog Power Center is theft.
Very easy setup. Just followed the instructions. Some of the rv parks have old power supply setups. I want to protect my 2003 airstream.
Watchdog Power Center is a great product if you’re looking to protect your rv investment.
It is new and I can't tell you how well it works. The service I received from etrailer when ordering was great. The hook up and wi-fi connection was easy. It is doing what you said it would. I will be going on a vacation soon. I will be checking it out.
Etrailer is very easy to do business with and very helpful. Wish they had price guarantee and free returns but they are way more helpful with everything than (say) Amazon. Good people to do business with.
This is a great device. We are at a park where voltage drops from over 120 V down to 110 V and less. This device “super“ boosts the voltage if it drops to 113 V saving electrical appliances throughout the RV, importantly, including, air, conditioners, and refrigerators and inverters. It is a wonderful device. And recommended strongly as it includes surge protection, and the surge module can be replaced if necessary.
I waited several months for this second generation to be made as first generation sold out, it turns out it was worth the weight of five months no fault of E trailer. This is constantly boosting my camper up shovel volts on both legs, but when people come home in the afternoon and turn their air conditioner on the power in this campground drops dramatically. I have seen it as low as 104 V at times on both legs. This does the trick I am going to add a plug near my auto rolling main wire and mounted permanently inside as I move from campground to campground and really don’t trust it outside even locked on a pole.
So far I love this thing as I have stopped opening the panel and looking to see what voltage I have coming in. With Bluetooth, I can just simply look at my phone and see how it’s working. I was also under the impression that it would temporarily boost the power, but I was wrong. It maintains the power that it generates so you constantly have the boost in voltage.
all good
Great unit if no one steals it. The design is fundamentally flawed that Power Watchdog didn't include ANY WAY to lock it to the pedestal. WTF were they thinking? Go ahead- connect your RV to this, go explore the area, and HOPE its still there when you get back. THIS IS NOT A TRIVIAL EXPENSE!

Hey there, you can certainly use a cable lock like 10' etrailer # e98891 and wrap through the handle of the cable, or the handle of the booster box to secure it to the pedestal. But I agree, would be nice if they had a built-in lock since they are not cheap! Let me know what you think. :)
The very first camp-spot we stayed at had low voltage and it worked flawlessly. Especially like that I can monitor it in real time with the app too. At one point the voltage dropped to 104 and it boosted to 114. Very happy with the purchase.
Nice device
Works so far as advertised. Sturdy construction. Fast shipping and good communication from etrailer.
Works wonderfully and compact. Glad to see combo surge and voltage booster in single model. I did an internal installation inside my Airstream. Tested at 30 amp outlet and it boosted 119 volts to 123 volts. I destroyed my RV refrigerator this summer at a campground with low voltage (107). I’m excited to see how this performs next time I’m in a similar situation.
We were having low voltage issues at our campsite, especially on hot and muggy weekend days when the campground was full. Our Hughes Watchdog would cut the power to our camper multiple times a day to protect our appliances. Since we switched to the power center, we haven't lost power once. It is so nice knowing we can keep our animals and ourselves comfortable on those hot, dog days of summer. It's well worth the price
Product works great at our camp site power goes low all the time and this booster will take 107v to 117v ish would recommend this for anywhere power is low
Shopped for the Watchdog Power Center e-trailer was my go to. Delivery was great a Plus in my book. So far I would say this is unit will give me peace of mind and safety. Plugged the unit in per instructions. The display is digital clear and brightness is adjustable. For the most part the app is nominal. It would have been nice since it is both WiFi and Bluetooth that if voltage goes out of range you would be notified. The app will only let you use it on just one of your devices. Could be why if you try to Use it on another device you will be logged out and then need to log back in. Overall I think it will be a much need safety device upgrade for my 5th. Thanks e-trailer for carrying good gear.
After some research and discovering through my existing gen to power watchdog surge / EMS/EPO protector that I had low voltage I immediately purchased the watchdog power station. Let's delete day one of use and as you can see from the screenshot the improvements provided. Very grateful for this peace of mind and technology. Etrailer assisted me in the decision making process and I received the product next day. The communication that etrailer provided was prompt and helpful.
I was having trouble at my campsite, dropping voltage and my watchdog constantly kept cutting power to my RV. That was happening every 3 to 5 minutes. I was losing power because voltage was dropping below 105v.
There was a lot of research and discovering this through an online forum, I ordered it. Don’t get me wrong. The price was a bit hard to swallow. Received it, plugged it in and immediate fix. It’s still a lot for what it does, but it does replace your surge protector ($350) and gives you the voltage boost. Worth its gold to keep power from fluctuating in my RV.
I purchased the 30 amp version even though my RV is a 50 amp. The park that I’m in for the next couple months is a 30 amp and it seems to be the 30 amp locations are where I usually have problems and this will plug in through a dog bone from a 50 to a 30.
I do still get voltage drops below what the booster can handle. It may happen once or twice a day instead of multiple times an hour.
Do you have a question about this RV Surge Protector?

I am sorry to hear that that happened to your Watchdog unit. Where did you have it installed or sitting on your RV? They don't have a locking feature but that is definitely something I will pass along as something they might want to look into.
