Suraielec Watt Meter, Plug-in Socket Power Meter, 90V-250V Wide Range, Backlit Large Display, Auto Cost Calculator, Overload Protection, Kilowatt Wattage Voltage AMP Tester, Electricity Usage Monitor

Got this for a few reasons and let me say it works better than I expected. Its very easy to use and easy to read. It has a back light that makes it easy to see when its in a dark space. It has some great uses, definitely good to have.

Man don't think twice. It works and I love it. Shows volts amps and watts at the same time. Plug my coffee marker in to it and was surprised to see 9 amps of draw at 119 volts. Anyway that said that is why I bought. I can now see what and how much is on one circuit with ease.

Amazing product and easy to use!

Great value! Works well. I used this for two purposes: 1) Tested voltage output, the breakers and load put in my little generator. 2) Showed my kid how much leaving the computer on all the time ACTUALLY costs us in Dollars! If you're an information nerd or need to monitor amps/watts/volts, this is great to have in the junk drawer!

This power meter does what it needs to do and seems accurate enough for home appliances. One quirk I noticed with the cumulative runtime counter is that it will not increment when no power is actively being drawn by the plugged in device. For example, I was measuring how much power our kitchen water boiler uses over the course of the day, and was puzzled when the meter only read say 8 hours cumulative time when I know that I reset it over 12 hours earlier, before realizing that the timer does not count when the water boiler is idling with negligible power draw. So the timer will not necessarily be accurate for devices that do not draw power continuously. The other improvement that would make this meter easier to use would be if the reset button wasn't one that required a pin to reset. The meter comes with one of those little SIM card eject pins, but it's a bit too sharp for the rubber reset button, and a thicker plastic pin would be easier to use, or have a raised button that can be reset by hand. It's a balance between convenient reset vs preventing accidental resets, but there are other ways to reduce accidental resets without requiring the pin (eg. put the reset button on the side).
