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%.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.You can measure the following with this meter in real time.VoltageCurrentWattsAccumulated powerCost in dollars and centsIt has three lines of data.The Top Line is time. It's the accumulated time that power has been flowing through the meter or how long a device has been plugged into the meter and that meter has been plugged into the wall.The middle line is power. It will either display the rate of power that's being consumed in Watts or kilowatt-hours and can also display the total accumulated power consumed.The bottom line is accumulated cost. You enter in the amount your power company charges per a kilowatt hour and then it calculates the cost based on that rate and the power consumption.

I am always curious how much electricity each device uses, this seems like a very good way to measure that. It is a little bigger than I thought, but most of the size is in the screen - so you get larger numbers to look at. Display not very good when looking from an angle, but this does not bother me. Overall pretty good product.

The display is difficult to read from any angle except straight on. The backlight makes reading even more difficult. The so called Instruction Manual is very poorly written. The English is terrible and the instructions themselves are pretty much useless. I'm going to give is a go to see if I can glean any useful information from it. I've had this unit less than 24 hours and so far the results have been disappointing. I will probably return this within the next day or two.Update: May 22, 2029 - I returned this meter today. Totally dissatisfied with the display and lack of a useful user manual made using this meter more frustrating than useful.

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. :-)This has nice functions like voltage, amperage, total cumulative kW/h, min & max wattage. Voltage and amperage are definitely in-line with expectations, so I'm thinking wattage is, too. You can enter your kW/h utility rate, but (only downside) it only goes to two decimals. I have a $0.113 rate, so I can only enter $0.11.

The meter seems to read watts correctly and does its job. That being said, the screen is exceptionally hard to read unless you're about directly in front of it, which can be a pain for wall outlets. Also, for a lot of locations energy cost is measured in decimals beyond the hundredths place (e.g. $0.1055 per kWh) but this meter doesn't let you get that refined.For less than $20 it is not bad, but maybe spend a bit more to get a better meter if what I've mentioned above is something you'd have issues with.

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.

As other users have written, the viewing angle for the LCD is set for viewing head on and from below the outlet; not from above it. One would expect that for something that plugs into outlets which are generally situated at knee or waist height the preferred viewing angle should be from neutral and above, right?The LCD screen gets flakey when the buttons are depressed, with LCD characters disappearing as if the LCD screen itself is being depressed.The user interface (keystrokes) to change/alternate functions are also kinda clunky and not intuitive.But, the functionality of the unit and it’s accuracy appear to be OK.As I just received it, I can offer no commentary on its lifespan or durability.First impression: I would try a different brand for my next purchase.

I built a cat shelter and it's about 50ft from my back door. On extremely cold days, I used to go to the shelter to feel the pad to make sure it was warm. I plugged the outdoor extension cord into this monitor and I use it to look at the watts. Because the HEATING PAD HAS A BUILT-IN THERMOSTAT, the display will show the WATTS being used, and other times it will be at ZERO when the thermostat cycles off. I just look to see the numbers occasionally and when it reads zero, I know that it is normal and that the heating pad is working properly.

I use this product to see the exact amount of electricity cost that certain products in my house uses, so I can see where most of my electricity bill is going in my household.
