Hughes has combined its amazing voltage booster and Watchdog surge protector into one single unit. The Power Center will keep your RV protected against electrical issues you're likely to encounter at a campsite.

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
Easy to set up. Works as advertised. No more dealing with poor quality electricity at the campground.
It is a very nice product, but no place to lock it down. All one has to do is cut the plastic handle and it is gone. It would hardly take any effort for someone to steal it, but it does work very nice.
Excellent product, rather heavy but works well.
Great for bumping voltage if you get low voltage plus full ems capabilities. Normally raises 2 to 3 volts on normal and ten if drops below 114 or so. It also has Bluetooth and wifi monitoring through their phone app but note wifi connection is 2.4ghz Only and doesn't work on 5.0 ghz at all
Great product. Easy setup
It works exactly as described!
Got this to replace the first-generation Hughes autoformer and its performance is better. The ability to check the voltage from your phone is a game changer. Definitely recommend if you are a full time RV'r and want to protect your electronics in your RV.
So so good. Easy to setup and get going. Had to turn off the neutral detection, I am not missing a neutral, so not too sure what is wrong with that. I have the hardwired power watchdog wired in after the power center and have never received that error on this same setup. Other than that working good. Boosted voltage from 110v to 121v.
In the summer when everyone's ACs are running you will often find your pedestal is providing <104 volts. This will kill your AC and other sensitive equipment. This is your best insurance policy for this and many other voltage related hazards. Get it!!
This is my second unit. The other went 10 years without a single issue and kept all the appliances in the RV (fridge, computers etc.) safely humming along. This new, upgraded unit is really impressive for its features. I can't imagine full time RV'ing without it given the poor state of electrical supply in many RV parks. Great piece of kit.
My Watchdog was delivered a couple of days early and arrived in good condition. Great communication from the folks at etrailer. It's easy to hook up - I've only had it in operation a few hours, but so far so good!
These autoformers have been on back order for a few months, but worth the wait. It’s nice to be confident in your electrical supply, especially in many older parks with varying power distribution systems. Hughes also provides great customer service and support.
Easy install inside my motorhome power cabinet!!!
We work camp at a park that has low power issues. We currently use a hardwired progressive Industries 50 amp unit. We ordered the Watchdog unit to assist with this. We put the progressive industry unit in bypass mode which required us to use the “RV neutral detection E8” in the disabled mode. We really enjoy this unit. It also provides useful information when you are away from the coach, being able to view the consumption/voltage.
I attached the neutral disable screen since it’s not intuitive.
Works really well. Connected to Wi-Fi and checked in-line voltage and exit voltage amperage and wattage. It absolutely does voltage correction if you’re confident it will protect my Electrical Components
Works good so far. Dipping down to 103 volts at my trailer park during peak heat, 2 acs running drawing 36 amps. Boosting voltage up to 113 reliably. Have only had the unit for a week.
Great experience, fast shipping, product arrived on the day they said it would...Product works as advertised .
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.

Thanks for the nice shout out Keith! I normally don't let the "A" word on the site, but I will let it slip this time =) As for the returns, call in to check fitment, if we get it wrong we pay for the return shipping.
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.

Glad to hear you are liking it, Jimmy! The wait was a bummer, but I don't think I have heard a single person that was unhappy with the upgrade as of yet. Definitely sounds like it was worth it! : ) Are you traveling around the country or do you have a few spots you tend to always go to?
Info for this part was:
At etrailer we provide the best information available about the products we sell. We take the quality of our information seriously so that you can get the right part the first time.

Glad to hear it was an easy set up, Anthony! RV parks are definitely starting to show their age, which can make them very cool, but it's definitely a good idea to be protected! : ) Where are you typically taking your Airstream? What has been your favorite spot?
