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.

Very good watt meter, and it has the level of accuracy needed to test power stations and battery solutions. It has an internal rechargeable battery as well.

This device works very well, with display showing Amperage, Voltage, or Watts. Only thing I didn't like, my receptacles are upside down (ground on top) as is currently advocated by the NEC, and the device has to be "upside down" to plug into my receptacles. I made a very short extension cord that allows me to turn the device "right-side" up after plugging into my receptacles. With that small modification, I'd give a 5-star review to this device, and would purchase again.

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.

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).
