About this item
- Wide Measuring Range: DROK plug-in voltage monitor measuring voltage range is AC 80-300V(110V, 220V), with a low consumption of less than 1W (about every 1200 hours consume 1 kilowatt-hour).
- Adjustable Potentiometer: There’s an Interior Potentiometer inside the meter for accuracy adjustment. Just use screwdriver to open the outer case and adjust the potentiometer with small size screw driver. Adjust the potentiometer counter-clockwise when it’s excessive voltage; if the displayed voltage is too low, adjust the potentiometer clockwise.
- Flat Plug: Designed as a flat plug, this volt tester can immediately detect and measure the current voltage by connecting to the switch plug or other kind of wall socket, simple and easy to use, it allows you to check on power health of devices for preventing the low voltage damage to your valuable household appliances.
- LCD Display: Built in Premium LCD digital display with blue backlight, this voltage monitor is convenient for you to view the data on it even in dim night. Moreover, it can be used as a voltage meter as well as a night light.
- Wide Applications: It is ideally applicable to measuring the AC voltage in family, office space, industrial and mining enterprises, etc. (Please keep the children away from the product & do not use the product in a damp environment.)

As an electronics engineer let me assure you that the old adage "you get what you pay for" more often than not is nothing more than marketing hype.
Let's be honest AC voltage meters aren't state-of-the-art technology it's actually been around for quite some time.
My only real concern is safety as this particular meter does not appear to have passed any insurance safety standards testing as I did not see any certifications for UL/ ETL/ FCC/ CE..
With that said it's such a simple device that I'm not overly concerned with it.
Be aware that most homeowners and RV insurance policies prohibit the use of non UL for non ETL listed devices.
In other words if the device causes a fire your insurance company can void your insurance and refuse to cover the damage.
As such it's always wise to check with your insurance company and see what their policy is regarding the use of non UL, non ETL listed line-level products..
I really didn't need this device as I have a complete Electronics lab full of very precise equipment but I'm kind of a test equipment junkie and was curious to see what I was going to get for five bucks..
I have to say I'm relatively impressed, its accuracy is as good as anything I've seen at three times the price. As such I have no problem recommending it.
The only problem with digital meters is that they react to slowly to see fluctuations in power levels. As such I always recommend using an analog gauge in combination with a digital gauge.
The analog gauge will show you rapid fluctuations in voltage that can indicate a problem while the digital gauge gives you a reference of the instantaneous voltage. If you ever visit a nuclear power plant you will notice that they use a combination of digital gauges and analog gauges on the same measurements for precisely this reason.
Anyhow the bottom line is it's well worth the money.

I had such a problem in out Park model, and monitored power for a season with this, to identify issues in the suppl lines. Fixed now, and thankful I had this little item plugged in to let me know it was a good time of bad time to use more power. Low power, shut a few things off, and keep the vitals alive.
