Hughes Autoformers RV 2130-SP, Voltage Booster with Surge Protection, 30 Amp

Well built quality unit. Works like a charm. One place we often camp is notorius for low AC voltage. This puts a lot of extra load on the AC unit which tends to go into thermal shutdown on really hot days. And here is Southern Arizona we get a lot of REALLY hot days. This unit solved that problem completely. Easily boosts 105 volts to 116 volts which reduces amp load and overheating on the AC unit.Not inexpensive, but a lot cheaper than having to replace an AC unit. Better cooling performance and reliability are a big plus. The extra surge protection is additional peace of mind too.

This product worked great. We went to the same camp with our travel trailer, in the dead of SC summer heat, on a super humid beach, which means our AC is cranking hard. Last year the voltages dropped down even to 108v and our AC was really struggling. We had a similar issue this year before I plugged in the unit, however after putting it inline or voltage jumped to 116-119, which doesn't sound like much but has a bit impact on the AC equipment. Value for the money is hard to explain to everyone. How often / long are you at a park, with very low voltage, where you are using VERY heavy AC draw? If the answer is, yes we have that issue, it really is a no brainer. If you're buying this as a replacement for a surge / line tester unit, you're better served spending your money elsewhere. In our case, we would buy it again in a heartbeat and hope it lasts many years.

Had to use a portable generator for the house. We have had problems with the generator voltage fluctuating and killing some delicate electronics. This unit stabilized the voltage and made a bad situation much better. I’m a fan

I saw the Hughes Autoformer at a camping rally. I thought the concept was interesting, but also thought the price was way too steep. I managed to catch a sale and ordered one. I have not used it much so these are just my observations based on two trips. I will update later as I gain more experience with it.First, this is no lightweight item. It has some real heft. There must be some really heavy-duty items in there. I also like that a locking cable was included in the package. While it is not what I would call a heavy-duty cable, it is like a lot of bicycle cables and will deter the casual, opportunistic thief. I also like that the surge protection is something that can be replaced if needed. It isn't like a cheap surge protector that just gets thrown out.Operation is simple. Turn off the power pole breaker and plug it in. Turn on the breaker. If everything is operating properly, the appropriate lights will turn on. If something is not correct, different lights will turn on and guide you to figure out what is wrong such as bad ground, reversed polarity, etc. If all is normal, turn the breaker off, plug in your RV's power cable and turn the breaker back on.So far, I have not seen the boost LED light up as the RV park were we were appears to have adequate power. It may be that we will observe it in the future. I am not sure how well it would work in conjunction with an inverter-generator. I think it is mainly meant for use with the power poles in campgrounds and RV parks. A inverter generator of adequate size will not have the voltage sags of an inadequately supplied campground power pole. It would have its own overload protection which would shut it down. Hughes would need to answer whether it would work with a generator or not.For the peace of mind, knowing that it will help my AC appliances to operate properly in a situation where the voltage sags. Did I need it? I could have done without it, but I think it will be a worthwhile investment in the long term.

This product is amazing and performs exactly as advertised.I have the Watchdog EMS and keep my RV plugged in while not in use. This is to maintain a stable climate inside to protect the furniture. It worked until I got the Watchdog EMS. When I plugged in the Watchdog, I found that on these really hot days my voltage dropped below 104 volts which caused the electricity to be cut off to the RV to protect the electronics. This happened almost all afternoon due to the grid not being able to keep up with demand in our small town. I plugged the booster in and it immediately gave me a 10% boost. I have not seen voltage drop below 110 volts since I plugged in the booster. Completely Happy with this product!!

This is a lot of money to spend for an RV toy. However, this is more than a toy, it is a great insurance policy for your electrical equipment in your RV including your very expensive batteries. In my mind, this is a small price to pay to have assurance that you will be protected and have ample voltage at parks with little reliable power.Recently a group of us were camping in a Michigan park where the voltage dropped to 104 volts due to all the other RV's running their AC's. This unit protected our RV while others in our group weren't so lucky. They had non-boosting protection and damaged their DC batteries along with some other components.I opened the unit upon receiving it (this is okay as this is what you need to do if you need to replace the surge unit) and examined the parts used to build the device. Hughes isn't gouging the consumer. They are using expensive, certified, reliable parts to provide a quality unit.Because this device does not have the bluetooth monitoring built in, I took the liberty to add some CT clamps on both lags along with connections to monitor the voltage to view remotely. This can also be accomplished by separately purchasing the model that does the monitoring with the Hughes app.
