Power Watchdog DVM1221 Digital RV Volt Meter, Plug-in, LED Display | Clear LED display gives accurate, real-time RV voltage readings, plus a built-in night light.

Easy to read. Works great. Very pleased. Going to order two more shortly. Very good product

Works as it should. If you need a quick reading of your voltage, this will definitely do the trick.

Great way to monitor the voltage in your home or RV. It’s “plug and play”, backlit for easy reading.

Wonderful Display!! Very bright easy to read.

I’ve only given 4 stars as after using for a month the reading seems to fluctuate a tiny bit. Otherwise great product and the most reliable I have found out there.

This was just what we needed shows exact temp and is great for night light also

The item works as described. I thought I ordered the one that charges color when the voltage drops dangerously low.

We bought this to go with the Hughes 30 amp autofomer for our full-time RV living. I love that it lights up at night for a little night light and I love being able to read the voltage on the wall when plugged in. The numbers are nice and big as well! Thank you!

easy to use and acurate very good tool for rv,ers

Use for my RV. This will help save appliances to now that power is not right

It’s good to have this little monitor visible in the Rv as it’s tracking the voltage

The display shows the voltage as it said it would?

This thing is a life saver when it comes to debugging any electrical abnormalities around the house.
