Digital Voltage Wattmeter Electricity Analyzer Monitor

Simple to operate, well built, nice features and, most importantly accurate. I tested accuracy by using it with devices with known wattages. I would highly recommend this product.

I got this to monitor my PC's wattage while mining ethereum on the GPU. The theoretical wattage for my custom system is 318W. The meter shows 210-215W while mining at ~31 MH/s on an overclocked GTX 1070 (memory speed +600MHz). I don't have any other way of measuring the wattage, so I'm going with it. :-)

I purchased to prove to my wife that our electric vehicle was not the cause of our electric bill skyrocketing. Five stars for working perfectly, zero stars because sometimes proving your wife wrong isn’t always the best idea ;) Very good recommend ....

I purchased this device to try and figure out how much power I was using for various circuits in my house. It’s easy to use to determine how many kilowatts your using for things like TV and Satellite box, etc. well worth the money!

These things are most informative. Most appliances use far less power, on average, than their label would indicate. Label shows Maximum possible draw for an instant, not the average.

Would be perfect if it would handle up to 20 amps. at 15 amps it's in overload. I did, accidentally hit it with 25 amps from my RV once for a couple minutes, and it's still working fine.

I purchased this item with the intent to use it on my desktop computer since it has a fairly high end CPU and GPU along with multiple monitors, so that I could see how big of an impact my computer system is having on my electric bill. Once you know what the electric rate charge is for your location per kilowatt-hour, you can enter that information in to the meter and it will automatically calculate in dollars and cents how much it costs.

I got nothing but an empty plastic bag in the mail. Will update when i have the actual product that I should have gotten the first time around Update: its now arrived and everything works. Pretty legit. Would be nice if the light stayed on longer tho. testing requires pressing a button over and over to wake up the light so you can read it. oh well, it was cheap.

I haven't tested this for accuracy, but it's close to what I would have calculated. It's easy to use just plugging it in to read wattage, or it has other features that can be explored more deeply.

I love this, it gives me that wattage I'm using and the amount of money I'm spending. It also lights up for dark environments which is a plus. So far I've had no issues with it.

Worked well to find the AC unit that was drawing too many amps.

Product works perfectly and as advertised. I compared the results with a voltmeter that has a built-in AC current meter and the results were extremely similar. The differences were less than 1%.

This power meter has helped me identify which electronics use the most electricity, helping me lower my electricity bill and even replace some outdated electronics.

My son-in-law seems to think it is a great thing to have.

Just plug it in and plug your device in--see the power being used--EASY!. I used this to add up wattage on the solar setup in my barn. Definitely helped.

This vendor was excellent. I had an issue with the product several months after purchase. They supported me long past the purchase. I would recommend 100%. Well Done, Thank you!!

When I was living with room mates and had a crypto mining computer I kept in the basement, I bought this to calculate how much electricity I was using to keep things fair when it came to the electric bill. This thing did the job perfectly.

great idea for this design. you can monitor your home electricity usage easily. it is worth for this price. i bought it for my mom's house.

This is so useful! I like that the display is lighted whenever pressed any of the buttons. Definitely makes reading easier. Didnt think so but youd realize once you look at it. Glad I didnt go with the pricier but better known brand that doesnt light up and looks archaic as well, lol. It really shows all the info although I wonder how do I see how many kW have my appliance consumed in $ since I added the price per kW in the system. It just wont show :( Either way, its good to see the consumption of anything I plug into it.

Worked well for my needs! Recommend

Like many others, my P3 P4400 Kill A Watt electricity usage meter started showing high voltage after plugged in for about a week. So wanted to have a try on this one. The large screen and backlight help to read easier. The viewing angle is around 110 degree, I guess. Not too bad, but can be improved. It’s able to check voltage, current, frequency, wattage, power factor, cost, and so on. I measure power and power consumption often so that I’m only concerned about these two items. I tested it by my low power led light. It read 0.5W while the defective Kill-A-Watt read 0.8W. I knew the correct value should be 0.4~0.5W, so it seems to work. Also I found it could record the minimum and maximum wattage in the process of measurement. Such function will be really useful for me. I usually check devices under 100W. This meter should work for me, I think. Give it five stars for now.

Works exactly as advertised. We got a couple of units from different manufacturers and I prefer this one. Nice display.

It works but the display I had a hard time to see the display in an angle. That I really need it to see the numbers but I need to come closer to see it. Otherwise it works Update. Excellent customer service. After a month of use still working strong. The display issue is not an issue anymore since I need to be closer on my pc to get a reading on the meter.

This is another really cool device to add to my gadget collection. I have my Dell laptop connected so I can keep track of how many Watts my laptop needs to build a homemade battery pack .....

Excellent energy meter, expanded functionality and intuitive use. Standard energy meter, comparable to the established/trusted brands on the market.
