BALDR U.S. Electricity Usage Monitor for Home - Kilowatt Meter Sockets - Wattage Meter Plug In Appliances to Measure Energy Usage - Home Energy Monitor with Easy to Read Display - Home Power Monitor

I love this electricity monitor. I use it continuously in the garage to record exactly how much juice I am putting into our EV, so I can calculate exact mileage. I have also used it on a temporary basis to measure the power usage of various 110V appliances in the house like printers, computers, router, refrigerator, microwave, CPAP machine, etc. It has various readouts. It gives very interesting insights into how much power the plugged-in item is drawing. It monitors instantaneous peak usage, and gathers usage stats over time. The reset button is small, recessed and therefore impossible to hit accidentally.

Shows current, wattage, max watts when motor starts up, and total energy until you push the reset pin. Works very well

Received promptly and in good shape. Instructions are rather cryptic, written by a non-English speaker, I suspect. However, I managed to get through the language problems and get it working properly. A rewrite of the instructions by a native English speaker, in "American" English would be a great help. Though the unit can calculate energy use and cost in euros and other currency, that isn't very important in the US. Unit seems to have plenty of functions to handle any job required for 120 VAC testing.

Haven’t tried it yet but I’m sure it’ll do what I need it for.

No instructions included in the box but it’s not hard to figure out. Found out my DJ system only pulls about 100 watts with everything plugged in. Looking to buy a battery power station and now I know what watt hours I need.

The unit works well as long as it's plugged in. Any interruption in power and it resets to zero. I replaced the button batteries and it didn't solve the problem.If you need it to hold memory... You may want to look at a different unit

The material and precision are quite premium! It helps me to check the power consumption of some devices before connecting them to my Ecoflow

I bought this power meter after seeing the significant number of purchases on Amazon and ignored the one star reviews that complained about the poor instructions. I should have listened to those one star reviews. The instructions, if you can call them that, are horrible and give almost no directions. They do go into great detail about how to read seconds, minutes and hours for the clock display, but that's about all you get. I am tech savvy and have a BSEE degree in Electrical Engineering and I can't for he life of me figure out more more than setting the clock and the electric rate. There are NO directions to re-zero the readings to start over for a new device you are checking for such things are Min/Max watts, cumulative time on the counter and such. The "Reset" does not do that but rather resets the entire device including the clock setting. There are no good instructions even to be found online, including the few YouTube videos that cover similar meters with the same design (clones) by other companies. This problem is especially true if you buy the two tariff (to rates structure) model. The device is just about useless except for reading the instantaneous Volts, Amps, Watts, and PF. You'll be sorry you wasted your money if you buy this. I am going to send it back for a refund in morning.
