Review on 💡 Energy Saving Electricity Usage Monitor: Briidea Power Consumption Watt Voltage Amp Meter Tester with 2 Outlets - Analyzing Device for Efficient Power Consumption by Tim Harrington

I tried to use this to control the continuous charge wattage going into the e-bike battery. It turned out to be a waste of time as the accuracy is plus/minus a full watt even though the display looks accurate to within a tenth of a watt. You'll be a lot smarter if you can get something like "Poniie PN1500 Portable Micro Electricity Usage Monitor" with an accuracy of 0.01W. (I checked by simply dabbing Briidea and Poniie in series.) Another flaw is that it lacks some sort of on/off switch that even a simple power strip has. And the display isn't backlit, so it's hard to read. Of course it shows voltage = 120 volts and hertz = 60 hertz. Does anyone really need to see this information? "Of course not, that never changes. strength factor? -- maybe, but to be honest I still wouldn't believe what it says. This is a waste of time and money.
