Hughes Autoformers RV220-50-SP, Voltage Booster with Surge Protection, 50 Amp

I would highly recommend purchasing along with this the stand that is recommended s as well as the cover. I purchased my first one from a local retailer. Those protective items were not available. After a little over two years out in the elements plugged into my rig and several rolling blackouts and power outages due to freezing, I finally had to replace it.Prior to having this device I could not run my AC on my 30amp rig if I needed to use the microwave. That was the first thing I tested upon installation. The power boost you receive on this solved that issue. Additionally the AC’s seemed to go into shed mode very rarely during our Houston TX summers with this.The only thing I would prefer to have on this that I have on the Hughes surge protector is the ability to see and reset it from my phone.Other than that I would highly recommend this product. We worth the money.

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!!

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 works smoothly!!

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.

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.

My seasonal park has really poor power. 30amp service and my fifth wheel is a 50amp rv. My air conditioner would trip breakers constantly if they park was busy or if it was hot out. I was getting about 106 volts with the aircon off and low 90s with it on. The autoformer bumped me up to 115-120 with it off and kept me above 106 with it running. I ran it this weekend for the first time and never once tripped the breaker.Despite the high cost it was still 1/4 the price of buying a newer more efficient air con.Other than it being quite expensive I was disappointed to hear it wasn’t waterproof. I made a waterproof vented box for it out of plywood and aluminum so it doesn’t overheat or get exposed to excessive moisture

This has completely solved the problem of unstable power at pur park. It was a game changer.

Arrived very quick right to door. We have a voltage drop issue (likely due to small line gauge used to site over general use in campground) whereby we start with near 120v until load is put on. This unit helps the issue but doesn’t entirely correct for it (may be beyond its scope of capability). The unit does boost as required but on our 30 amp circuit, any 2 medium to high draw items (such as hot water heater and portable toaster oven) we still only get 110-112v so we have to be careful what we use (those two items admittedly are fairly high like 9-14 amp each maybe?). However what it DOES provide is peace of mind that it’s being regulated automatically and I don’t have to unplug/plug a raw booster that I used to use when I needed more power... that provided too many Volts when requirements were not needed (like 130+). So this aspect is great!——I should add for extra clarity that without the Autoformer trying to run 2 heavy draw items would be impossible as the voltage would be far too low to be safe.The item comes (as it says) with a great handy plug in volt meter. During the initial test my manual meter and it both read 117v. We turned hot water heater on, briefly dipped to 109v +/- then came back up to 115v so the device is doing the boost as expected. Highly recommend if you are experiencing power issues with your RV!

We have a 50 amp RV parked in a seasonal 20 amp site. Not ideal, but it’s what we have. This thing is amazing! We had voltage dropping to 90 on busy, hot weekends, and it was around 105-110 at its very best. Now we’re hovering around 115-120v. It’s a definite relief to have it, and the surge protection is the cherry on top.It was REALLY nice not to have to order this direct from Hughes because we would have had to “re-ship” it since they can’t legally sell it to us here in Canada. It’s worth noting that it is NOT CSA approved. Not yet. We were all set up to ship it using a re-ship service to get it into Canada, but it would have cost us more to do it. This was an expensive purchase, but it’s worth it for peace of mind.

Hughes Autoformers RV2130-SP Voltage Booster works great
