Watt Meter Power Meter Plug Home Electricity Usage Monitor, Electrical Usage Monitor Consumption, Energy Voltage Amps Kill Meter Tester

This works well and isn't intrusive. Easy setup too. Just find what you pay for electricity, per KW/h, enter it and it's ready to go. The only thing, which I hope they'll address is that the LED backlight is wsy too bright with no way to adjust the brightness without adding a modification on the PCB itself. Other than that, very nice product at a very reasonable price.

I am getting VERY HIGH electric bills and have been looking to find out if some appliance I am using regularly is sucking up the juice. This meter is perfect! Just plug it into the wall socket, then plug in your appliance, and within seconds it will show you the wattage used. There are other settings like KW measurements, as well as cycles and voltage, but I bought this mainly to use as a wattage meter. LARGE display, easy to read, and priced right. HIGHLY RECOMMENDED!!

Works well and a lot of fun going from appliance to appliance :)

Absolutely love this device and was only $10 bucks! Has an easy-to-read LCD that is backlit with clear large numbers. A press of the M (mode) button toggles through several different readouts, including Watts, Kwh, Voltage monitoring, and more. Can also enter the price of a kwh in your area and it will readout what the device is costing in electricity. I prefer this design, seeing just one readout at a time (with the mode button to switch if you want), vs screens with multiple readouts on the same screen, making the readouts smaller, cramped and harder to read. It also feels durable, and came with a sheet of instructions that had font you can actually easily read, though it's so simple to use, you probably won't need them. I've only had it a few hours and can't imagine being without it. If something happened to it I'd replace it in a second. Great buy, very happy!

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.
