Video Transcript for Review of Hughes Autoformers RV Surge Protectors - Voltage Booster - HU57FR

Hello everybody, this is Jeff at etrailer.com. Today, we're gonna take a look at this Hughes Autoformer 50 Amp Voltage Booster with Surge Protection. Now, this will give you complete RV protection, all in nice one box. This will help prevent any low voltage, which could damage your RV. Basically, your box, right here, will plug into your short power, and then your RV cord will plug right into the box here. And how this Autoformer works, basically, as you're in the RV park and then the visitors begin turning their air conditioners on, their TVs and other appliances, the park voltage will drop.

Now, this will create a dangerous situation, where appliances will draw more amps, and create more heat, because they're not getting the voltage that they're designed for. And this overheating results in premature death of your appliances. So, what's nice, is this box here, will constantly monitor the park's voltage, that's entering your RV, and when it drops to 113 volts, the boosting will begin, and now you're subtly getting your 123 volts. And you'll notice the big difference in your air conditioning airflow, and even your brighter lights. Now, this voltage booster increases the volts going to your RV to protect the electronics from low voltage damage.

It'll boost the voltage by about 2%, while in the standby mode, and it begins boosting your voltage by 10%, when that voltage is 113 volts or lower, and it will shut off when the unit receives 90 volts or less. Does have a built-in surge protector, which will protect the unit and your RV from power spikes. It does offer about 48 hundred joules of surge protection. I did wanna zoom in, just to show you the front of the box. That front of the box will, pretty much, tell you everything you need to know.

It uses LED diagnostic lights, right here, and it'll show if the park power pedestal is providing stable power to you. The boost indicator signals, right over here, there's two of them. They will stable signal when the unit is boosting voltage. Over here, when you first plug it in, there's four LEDs, and if all of those, all light up green, that means you're all ready to go. If any of them are red, you don't wanna go any further, means the power is unsafe.

Now the cord will let you place the voltage booster in a nice safe spot. Let me zoom back out here. You see it's a long enough cord, that you can put it where you want to. It does even come with this nice cable lock, that you can actually lock it, so nobody tries to take it. The copper and wire will provide excellent conductivity. And this part in made in the USA. Few dimensions on this, the length of it, in the center's about eight and half inches wide. Height of it, is gonna be right at about, including the handle, about 12 inches tall. And the width of it, is right at about five and a half inches. The cord length, we mentioned, is gonna be about 54 inches long, amps is 50 amps, and the wattage is 12,000 watts. But that should do it, for the review on this Hughes Autoformer 50 Amp Voltage Booster with the Surge Protection..

Order was delivered days before anticipated. Products arrived exactly as expected. Easy installation I could do myself. Within 30 minutes had Autoformer installed within RV and all electric working properly. Thank you for the prompt response to my order. The video of the install and product features eTrailer provide are excellent.

Replaced Progressive device which constantly dropped out due to low supply voltage. Huges Autoformer instantly corrected that problem.

Have not used but from other reviews it appears to be a quality piece of equipment. Great pricing and very fast shipping from etrailer. It often seems as if items have already shipped before the order is complete (LOL) as they are very fast.

Review from a similar Voltage Booster in RV Surge Protectors


The product is fine however I would like to mention Kristina* over at etrailer, had an issue and not even 10 minutes later she got on the horn and another call came in letting me know it was fixed. It’s hard to get anyone to do their job at all. Girl needs a raise!
