Upgraded Watt Meter Power Meter Plug Home Energy Monitor Electricity Usage Monitor, Electrical Usage Monitor, Energy Voltage Amps Meter Tester with Backlight, Overload Protection, 8 Display Modes

First off, I own multiple Klein and Fluke testers. I still use these for multiple applications. Each of these cost in the excess of $ 100.00. I always need to remove their batteries so that the batteries don't leak and destroy the tool. It's a "best practice" thing.Here's the cool things about this tool, it's inexpensive and it doesn't take batteries. You plug into a socket, and it's powered automatically. I checked it for accuracy against both my Klein multimeter, Klein socket tester, and Fluke inductive testers. It was dead on for all measurements: Volts, Amps, Watts, etc.Here's the question: Why would I use this if I wave the other meters? Well. this is quick and easy, and I hate reinstalling batteries in each of the other devices.If I have multiple circuits to check or troubleshoot, I'll beak out the Klein and Fluke tools, but if I only have a couple of things to check or I didn't have multiple hundreds of dollars to spend, this tool is a very reasonable substitute.The only drawback that i can see, is that this tester resets back to W (watts) every time it's unplugged. It's a small annoyance to cycle to one of the other measurements. It only takes a few seconds, but it's an annoyance.Note: The directions are a little weak. To cycle what is being measured, you hold down the (M) button for about 5 seconds, the screen will flash, then tap the (M) button again until you see the proper field you want to be measured. It only takes a few seconds.I would definitely recommend this tool.

Works well and easy to use!

I got this cause i didnt want to spend 3x the price on the name one with the intention to return it if it was not accurate or didnt work as advertised. I tested it with a 65W charger and a usb C cable that will read out the wattage. I was getting 61W out of the cable but 65W from the wall. Even in pitch black environment the brightness on the display makes it easy to read.I was curious about how much wattage my gaming laptop with a 180W power brick would use to game since it can also power itself with 100W USB C. at max settings with a battery charged i was pulling 110W from the wall which wouldnt be attainable with usb C but on silent i was only using 70W. This device helped me learn that i could game even away from an outlet as long as my battery is fully charged and i only game in silent mode since the 100W usb C cable would be able to provide enough wattage. These are easy to use since it just goes over your existing outlet and you use the plug on it like a regular outlet. Try it out if you are curious about how much watts your electronics use.

So far, so good. I'd have given it 5 stars, but you can't rotate the part you plug into the wall so the unit is big and upside down at least in my house. I know they used to install outlets upside down so if the cord started to fall out of the outlet, it would be the ground plug and not the two prongs. That has presented itself with complications for the 30 years I've lived here. Had to use an extension cord and plug that Into the outlet, then plug the meter into the extension cord, then plug the item to be measured into the meter. Has all the essential data points you'd want to measure. Has a nice user guide to explain how to use this. So far I'm very satisfied.

If you're curious about power consumption this is a handy little device. I've used it for space heaters, electric kettles, and various high wattage devices. It may not have a memory but it provides me with information I otherwise wouldn't have. For $10 I'm pretty impressed. It's well made with good fit and finish and it's easy to use. Now if I can just stop myself from measuring everything in the house! ;-) :-)

Does everything perfect. Simple operation. Only thing I wish it had was an hour meter, but they never claimed it did.

Handy tool to read power pulled from the wall. Great for monitoring power usage for my computer builds. The quality is quite amazing for the price and its simple/straight forward to use.
