Reliable voltage at RV Parks After having a heatpump/airconditioner fail in my motorhome due to low voltage at an RV park, I purchased the Hughes Autoformer last year. I have had good voltage as we travel from RV Park to RV Park and I feel comforted knowing that I am now also protected from surges and spikes.

Intermittent False Errors and Poor Product QA/QC It worked well for the first day then it started giving error codes E7 or E1. I thought I had an electrical problem at first, but then realized that a slight movement of the surge protector fixed it. I’ve done it several times so I’m certain there is a defect inside the surge protector. It also doesn’t wait the 90 seconds like it is supposed to. Just lightly tap or move the protector and the error immediately goes away.

Not knowing exactly how this thing… Not knowing exactly how this thing works, I still have a level of comfort knowing that its doing its job. The issues I've had are with the ground connection and the neutral connection. At my house, I have a 50 amp hookup. These regularly illuminate red when I first hookup. Hours later I'll check, and theyll be green. Dont know what to think about that. I like the weight of the device but I'd like it to be a little more weather proof as mine is starting to show sun fade and maybe even a little rusty in places.

Don't Leave Home without It! One of the first things we purchased before taking possession of our first Travel Trailer was buying the 30A Autoformer. This decision was based on reviewing online recommendations about possible electrical problems you can encounter while traveling and staying at different RV campgrounds. We have been very fortunate during our many stays over the last 3 years to have only encountered one campground that had a bad electrical problem that the Autoformer detected. We were able to bring the problem to the office and they immediately repaired the problem. We feel this device can and will assist us any time we pull into a new location or even during long stays. My recommendation Don't Leave Home without it.

PWD50-EPO-H not working I bought a PWD50-EPO-H and installed it correctly in my 2023 Airstream. When plugged into a 110 outlet in my storage area, I get a E6 error message. E6 is "Line Two Neutral Reversed" - it isn't wired wrong. I checked the electrical outlet and it is wired correctly. I tried two different 110 to 50 Amp connection adapters, one new and one I've used and had for 10 years. I have called Hughes 5 times, and noone ever answers. I have left a message, three days later no returned call. Apparently they have NO technical support. I am super disappointed, and can't use my RV. Update.............. 5/2/2023 After posting this review, Hughes called several times and were very nice. As it turns out, after leaving my RV plugged in for about eight minutes and the WatchDog resetting 2 or 3 times, the error magically disappeared, without me making any wiring changes. I then unplugged and replugged in the RV several times, and still no errors. I pray it stays this way forever. I am looking forward to the Bluetooth connectivity. Being optomistic here.
