Review on Poniie PN2000 Plug-in Kilowatt Electricity Usage Monitor Power Consumption Watt Meter Tester with Extension Cord by Isaac Samal

Interesting Why did they choose this to show the cumulative time and not the absolute time? In other words, for example like my fridge, which I'm checking consumption now, if it's not working, the consumption is 0.00 watts. Big. However, the cumulative timer counts minutes ONLY during power-up. So. While it's great to know how long the fridge has been on, this unit of measurement doesn't reflect the time that has elapsed in real time. So I have to log exactly when I start and stop the 24-hour test and calculate the consumption myself. The official Kill-a-Watt meter will do better for you. Otherwise the device works perfectly, the display is sharp and easy to read, the short extension cable is handy (could be longer!) and that's all there is to say. It is very interesting to observe the variable consumption of a computer switching power supply depending on what you are doing.
