Power Watchdog Hughes Autoformer PWD50 Watch Dog 50 AMP Surge Protector

Perfect addition to keeping your travel trailer safe when hooked up to power at parks. It only takes one time to fry your rig so why take the chance. This is easy to plug in, feels beefy, and works well. The app is easy to use and you can see your real time data. I like that you can replace the circuit board on the inside if it actually takes a hit rather than replacing the entire thing like cheaper ones.

Needed to upgrade our camper. So happy with it and have not had a problem with it yet.

Works as intended, happy with the unit

I purchased this Autoformer December 2019. This is the 2nd one that I have bought. The first one was around 25 years ago. That one weighs a ton. By the way it still works just fine. It stays at home on the RV pad so when we are there we use it. Now the new one that we carry with us weighs about a pound. This little baby is really awesome. It protects the 5th wheels electronics plus you can also see via the app the power consumption and also if there’s any issues with the electricity. As far as having any issues with connecting it to my phone there aren’t any. It was simple and easy. Oh by the way I’m 70 years old. 😁 Would I recommend this new one? You can bet your sweet tush I would!

Perfect for use on a standby portable generator that doesn’t have wattage or amps meters. Updates once per second over Bluetooth so you can monitor your house load during a power failure. Most important, this provides amps per both 120v inputs so you can better balance loads and avoid generator from tripping both breakers off because only one side exceeded generator breaker rating. Also monitors voltage per each 120v side to also help you lower distortion by you balancing house loads across each 120v leg to reduce distortion and led flickering by managing voltages to be close to equal. A little pricey, but priceless in an outage to let you know how much stuff you can power up to the limit of your generator.
