A quest we get asked is “What causes a surge or spike?”
Essentially when you’re at an RV park and everybody is plugged in, you have electricity running through the wires from the park pole into your Watchdog or surge protector, into your Autoformer or whatever, going into your coach. Everybody is plugged in, they have a lot of draw or load on the line – their AC units, water heaters or microwaves working – there’s electricity flowing through the wires into that coach. If somebody doesn’t shut down or unplug from the pole properly, you can have a surge or a spike.
Picture electricity like water flowing through a pipe. If somebody goes to the pole and just yanks their shore cord out of the pole, that electricity – that water flowing through the pipe – hits a wall and has to go back through the powerline and can easily have an effect on anybody that’s still connected around that RV. So, a surge can be caused by your neighbors.
Obviously, if there’s a distant lightning strike hitting the ground or power lines, you can have a surge or spike that way. If it’s windy and you have power lines that are arcing, you can have a surge or spike. Even just simply turning on and off large equipment – washing machines, electric dryers, or devices with a high amp load – they can cause surges when they kick on and turn off. You’re essentially changing the flow of electricity. It’s this sudden change that causes that surge or spike. It can either go into your RV or somebody else that is near you if they’re still connected and you’re sharing some wires.
So essentially, you do want a surge protector. It is something that is necessary to prevent damaging surges or spikes.

Absolutely great piece of gear and a must have for your RV, trailer or fifth wheel. Quality is top notch and it’s made in the USA. I highly recommend it.

I first saw one of these at a camping rally. I finally picked one up. I have used it only a few times. I don’t think I have encountered a situation where it needed to perform the boost function yet. However, I like having the peace of mind that it will be there and will work if needed. I also like that it isn’t a throwaway piece of equipment and that if it is needed, the surge protection module can be replaced for a very reasonable price. I did not get the internal hard-wire kit, but may get that and mount it inside so it is both secure and out of the weather. It is much more expensive than a surge protector, but then I expect it to do so much more. As was also mentioned, I am very happy that it is made in the USA.

After watching some videos full time RVers : I was able to talk my wife into the admittance fee of peace of mind… what I mean to say is… before we went on our maiden voyage; I installed the 30 amp Hughes Autoformer: and was I ever glad that I did!
The very first night we experienced low voltage in the very first Park we stayed in! But the Hughes Autoformer took care of us and everything worked!!!
I’m an aerospace Machinist by trade and I like to have my gauges tell me the state of affairs… the voltage dropped to 109 at the pole but we had adequate voltage the run our air conditioner and hot water heater as we left our pet in the 102 degree TEXAS outdoors Heat! We were shocked to see the low incoming voltage… but the Hughes autoformer kept it close to 120 volts ac!!!
Great job! 🙂

After getting “flipped off” several times for undercurrent, this unit comes in really handy. Another expense, for sure, but campgrounds don’t always supply the cleanest power. This unit guarantees you can still run more than the bare necessities. In some places, it’s a must have.

I’ve had to use my Hughes Autoformer in various rv resorts over the past years. It has saved us and kept us powered up numerous times. I will never be without this or the Power Watchdog I’ve recently purchased. Thank you for these wonderful products.
