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.

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.

Happy Voltage equals a Happy Camper! I have the Hughes transformer/protection on a 45’ class A Motorhome and I am fully aware of the ability to “boost” the voltage 2-4 volts when an RV park or campground is experiencing huge demand. I always have 120-124 volts ac on my monitor and have never experienced any appliance damage. I sleep good every night knowing the Hughes transformer/protector maintains safe voltage on my 50 amp service. Charles Thomas Zellwood, Florida

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.

I purchased this unit 2 years ago and… I purchased this unit 2 years ago and it was in use a total of 10 months ,it is completely dead now ,not sure that it really made any kind of a difference to my RV ‘s electrical performance at all,
