Video Transcript for Hughes Autoformers AC Digital Voltmeter Feature Review

Hi there. I'm Michael with etrailer.com. Today, we're going to take a quick look at this dual color digital voltmeter. This is going to measure the voltage coming from your outlet, this is going to be great for monitoring your power on your RV's, boats, in your house or in your office. This will measure between 90 volts and 132 volts with an accuracy within 0.5 volts. Very easy to use and get set up.

Basically just plug it in to any outlet and it will turn on for you. You can see the LED screen is going to give you your volt readout, but then the background is going to have two different colors, but turn off the lights here you'll be able to see that a little bit better. So, green means the voltage is within an acceptable range which is between 108 volts up to 132 volts. If it goes red, that will mean that the voltage is outside of the acceptable range. There we go.

So you can see that red there. When I pull it out that red will indicate that there's something wrong and you need to address it. So really easy, convenient little device here. It is very small. It's only about, about two and a quarter inch just shy of two and a quarter inches wide by just over one and a half inches tall and right about one inch deep.

So it won't take up much room at all. Just put it in one of your outlets and be able to keep an eye on the power coming in to your RV or boat or other outlet. So that's going to complete our look for today. Again, I'm Michael with etrailer.com. Thanks for watching..

@Troy We're glad to hear that you're happy with the # HU28FR digital voltmeter!

Would highly recommend for low voltage issues.
Great
product!!

I purchased 2 of these voltmeters to watch both power legs in my motorhome. I like the red indication because it is a visual reminder there is a potential issue.



by:

This is a simple little "tool" that we plugged in an out of the way outlet above the kitchen counter. It is nice to now what voltage the park is delivering and what voltage the trailer is at. This unit is nice as it is normally lit with a green display but will turn to a red display with very low voltage.



by:

Excellent product, don't travel without one.



by:

I haven’t had a chance to use the product yet therefore I can’t comment on it. But etrailer customer service was great and the sale price was the best I see anywhere. I received the product promptly and well packed for shipping.

  • Questions on Hughes Autoformers AC Digital Voltmeter & Surge Protector
    The Hughes Autoformers AC Digital Voltmeter, # HU28FR that you linked to is for measuring voltage at an operating range between 108 to 132 volts. This is irrelevant of the amperage supply from the pedestal. If I understand correctly that you are wanting to monitor amps being supplied to your RV, I suggest a surge protector. From Hughes, we have the Power Watchdog Surge Protector, # HU97FR for 30 amp and # HU47FR for 50 amp. The 30-Amp or 50-Amp surge protector offers 6,100 joules of...

  • Troubleshooting A Jensen RV Stereo That Randomly Turns On By Itself
    Hey Jeff, The Jensen stereo in your RV can randomly power for a few reasons. Depending on the model you have you could have a setting checked to turn on when there's a NOAA weather alert. If this is happening when there isn't rain in the forecast then we can rule that out but it wouldn't hurt to roll through the settings any way and make sure this feature isn't turn on. You can also check to make sure there isn't a sleep timer/alarm set that's causing the unit to power on. If your unit...
