Tired of low voltage or power spikes, try this I got tired of low voltage damage to my RV components. The last time I replaced the refrigerator circuit board, I got the Hughes 30a autoformer. I haven't had a surge or low voltage problem since. It works flawlessly without constant monitoring. THANKS HUGHES!

I purchased an autoformer… I purchased an autoformer transformer/voltage booster after having low incoming voltage on my 45’ Holiday Rambler Navigator. Before installing the autuformer the Navigator would shut the power off because the voltage at the park was too low. Problem solved and now I would not want to be without the security of knowing that the Incoming power Is correct. Great investment for peace of mind.

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.

I have your 50 amp Watch Dog Surge Protector Thank God I have your 50 amp Watch Dog Surge protector I always questioned why I needed it. I was on holidays on Manitolin Island at a camp ground 30 Amp hookup. My power kept cutting out checked my watch dog app at a total of 10 amp consumption my voltage was dropping to 104 Volts and tripping out. Thank God I didn't need air conditioning at the time I probably would have burned it out. Great product I would highly recommend it.

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
