Power Watchdog PWD50EPO, Bluetooth Surge Protector with Auto Shutoff, 50 Amp, Portable

The Power Watchdog PWD50EPO brings smart protection to your RV’s electrical system. This portable 50 amp surge protector combines 6,100 Joules of advanced surge protection with Bluetooth connectivity, allowing you to monitor park power conditions right from your smartphone using the free mobile app.

World’s First Smart RV Surge Protector

Power Watchdog (formerly Hughes Autoformers) was started over 25 years ago when an RV owner and engineer named Robert Hughes set out to solve the problem of low campground voltage that was damaging his air conditioner and refrigerator. He created and patented the Autoformer in 1995, and the company has since served more than 100,000 happy customers. The Power Watchdog Smart Surge Protector became the company’s best-selling RV power protection product on the market, redefining the category with its patented technology and iconic glowing bulldog face indicator.

Emergency Power Off (EPO) Protection

The EPO feature is what sets this model apart from standard surge protectors. The unit automatically shuts down power if voltage drops below 104 volts or rises above 132 volts. Once power conditions are good and stable for 90 seconds, the unit will turn back on automatically. This smart circuit analyzer will shut down power to your RV if a dangerous event occurs, and an alert will be sent to your smartphone. A built-in 90-second power-on delay after a fault protects your AC unit from damage during restart.

Real-Time Power Monitoring

Wirelessly monitor voltage, amperage, and wattage on your smartphone in real time using the free mobile app. The Power Watchdog features the oldest and most reliable phone app in the business, giving you complete visibility into your RV’s power consumption. Plug-n-play ensures a minimal 4-second power-on analysis to determine if power conditions are safe, while other brands can take up to two minutes.

Complete LED Park Power Diagnostics

Complete LED park power diagnostics with wireless fault alerts ensure you are aware of any hazardous park power conditions. The unit monitors for open ground, open neutral, reverse polarity, open circuit, and miss-wired conditions. Customizable alert thresholds warn you when conditions fall outside a specified range that you set in the app.

Replaceable Surge Module

Should you get hit by a large spike, simply order a new surge module rather than replacing the entire unit. This patented feature saves time and money by allowing you to swap out just the surge module after a spike, meaning no need to replace the entire power surge protector. The unit comes with a limited lifetime warranty.

Rugged Outdoor Construction

Built for the outdoors with an IP65 rating, the Power Watchdog is rated as “dust tight” and protected against water projected from a nozzle. This durable, weather-resistant design thrives in any weather conditions you’ll encounter at campsites. The heavy duty construction is built to withstand everyday use at your campsite.

What RV Owners Are Saying

One verified purchaser shared: “Installing the Power Watchdog PWD50-EPO-H paid off on our first camping trip! While staying at a US Corps of Engineers campsite we had an electric event when a camper plugged into the pedestal next to us. I was not there at the time but my wife heard a loud ‘POP’ when they plugged in, then our power went out. A few moments later our power came back on with no damage to any of our equipment. I would say our purchase was money WELL SPENT!”

Another customer noted: “This is my second one of these power monitors to have. My first one was the 30amp Hughes Watch Dog EPO, and it was fantastic, and a great piece of mind. I bought this one because I now have a 50 amp camper trailer, and it works great. To me it is extra insurance to protect my investment.”

A park model RV owner commented: “I have a park model RV that does not move around a lot. Even without changing power sources I have found this to be very useful. It prevents overdrive and it lets you monitor power consumption across both circuits. I use two 25A circuits, the ability to monitor them and move devices to the lighter circuit proved very useful.”

Easy to Use

Simply attach the Power Watchdog to your RV’s power source, download the mobile app, and use it to monitor your electrical system instantly. The app allows you to see the amps being pulled on both legs of your 50 amp coach at the same time, which some units do not offer. The clear display turns red with a specific error code when a problem is detected, and you’ll receive an instant notification on your mobile app with a detailed explanation of the error.

Made in Anaheim, California

Power Watchdog products are manufactured at the company’s 5,000-square-foot facility in Anaheim, California, located near Pacific Transformer’s headquarters. The company is led by President and CEO Pat Thomas, who took over the company in 2010 and has guided its transformation into a leader in smart RV power protection technology.

Protection Against Common RV Power Issues

Power Watchdog solves the common problems RVers face with unstable campground power—like low voltage, dangerous power spikes, and unreliable connections. The patented voltage boosting technology, smart surge protection, and real-time power monitoring are engineered specifically for the demands of RV life. Whether you’re dealing with electrical issues from neighbors plugging in improperly, arcing power lines, or distant lightning strikes, the Power Watchdog provides the protection your RV needs.
