Flat US Plug AC 80-300V LCD Digital Voltmeter Voltage Measuring Monitor, AC 110V 220V Voltage Panel Power Volt Test Monitor Gauge Meter for Household Plug into Outlet to Measure Voltage (1)

After experiencing low voltage (105) only realizing it after equipment failure.. 10-15 volts low may not seem like much but after prolonged period it does damage to your appliances… our power company confirmed low voltage and corrected the issue which affected everyone on our line although they never were aware.

Bla bla

When there is high demand in your grid say super hot days or super cold days, your line voltage may drop.

These are exactly what I need. New construction and I was wondering if the electrical was up to snuff. And I found out that it is! No brain power needed to install - just plug it in! Once our house project is finished I plan on using in the RV to check on voltages as we travel.

This is great for rvs to make sure the park has proper voltage.

These are great little electric testers. I use all the time at work. Love the led reader which gives me the correct voltage when I plug into a wall outlet. Highly recommend them. Thanks.

I liked the simplicity of the product - simply plug it in. It only takes up one outlet slot, and the readings are large enough to be read at a distance. Although I did not measure the absolute accuracy of the reading, all three units had the same reading. Haven’t had the devices long enough to assess longevity. For me the value was worth the price.

Use in my RV to monitor use. Easy to read.

Easy to use - just plug it in and verify the ups and downs of the AC voltage. My utility was pumping a 5 to 6 volt varying voltage (119 - 125 volts). It also a nice to have voltage indicator for the portable generators. Its also a nice Nite-Lite.
