Power Watchdog Hughes Autoformer PWD50 Watch Dog 50 AMP Surge Protector

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

Used mine for 4 years and had no issues enjoyed the Bluetooth monitoring, app worked well, liked being able to check parks power before hooking to rig. Then is paid for itself big time. Had a power outage and when power came back on it sent a surge and "Big Dog" (what I named mine) did its job and took the hit, no damage to RV. It blew its surge protection, and must have taken a big hit, prevented one leg of power coming to RV. I called customer service, and they were very helpful and said even though it blew the surge it shouldn't be preventing power to the RV, asked for pictures. I sent pictures and they replaced the unit. I now have Big Dog 2 watching over my rig. Highly recommend, you don't need it until you need it.

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.
