Key item features

  • Various Monitoring Parameters: The energy meter can monitor appliance power (W), energy (kWh), voltage, amperes, hertz, power factor, cost, minimum and maximum power (W), cumulative days, and time. By switching between seven display modes, you can easily understand various parameters of your appliance's operation. The home energy monitor also calculates and displays how much electricity your appliances use and the cumulative electricity cost.
  • Upgraded LCD Display: With a large 2.36" x 1.85" screen and a clearer display backlight, our electricity usage monitor displays data more clearly and distinctly, day or night. The full 180° viewing angle is perfect for reading and recording data from any angle. No need to stand in front of the display and bend over to read the numbers.
  • Adjustable Backlight Timer: Our upgraded watt meter has five backlight timer options. The default backlight timer is 10 minutes (bL-0). To change the backlight timer, press and hold the "UP" and "DOWN" keys simultaneously to enter the backlight timer settings. Then, press the "UP" and "DOWN" keys simultaneously to select the backlight timer (bL-0 = 10 minutes, bL-1 = 1 hour, bL-2 = 4 hours, bL-3 = 8 hours, bL-4 = continuous). Finally, press the "COST" key to save the backlight timer setting.
  • Overload Protection: When the device power exceeds the overload rating, the LCD will display "OVERLOAD" to warn the user. All buttons will stop functioning until the load power is reduced or removed. The default overload rating is 3680W and can be adjusted between 0 and 3680W. Typically, the overload rating should be set to 1800W before use. Press and hold the "Function" key for more than 3 seconds to enter the settings.
  • Data Storage: When you unplug the meter from the outlet or remove an appliance from the power monitor, the meter records your electricity usage data. The next time you use it, you can directly view the last data. This feature also automatically saves data in the event of a sudden power outage.

Plug in Watt Meter

I ordered this watt meter to check household item wattage requirements when they are running to better plan the items that could be operated at the same time on my backup power generator when an outage happens. The watt meter is back lighted so the digital reading is easy to see. There are multiple settings in addition to watt readings such as cost at price per kwh, usage over a period of time, backlight time out, and others. I will only use as needed to verify the generator is running 60 hertz also. I included some pictures with a quartz heater connected. Each heat level should be 500 watts but the total looks to be 1229 watts on a 1500 watt heater.

Great way to reduce your electric bill!

When I was growing up, my mother had a large deep freezer. Over the years, her electric bill crept higher and higher, and we thought it was just inflation. Then, she got rid of the deep freezer, and the electric bill got a lot lower! She could have afforded to eat every meal at a nice restaurant, for what she paid to "save money by cooking at home!" If your electric bill is too high, and you don't know why, this little gadget will help you figure out the actual cost to keep each thing running. You just plug it into the wall, and plug your appliance into it, turn the appliance on, and push a few buttons. You can compare an electric space heater to an electric blanket, or decide if it's time to upgrade - or just get rid of - that deep freezer. You can even show your kids exactly what it costs per month when they forget to turn off their lamp or video game console ; ) Great tool for saving money!

I bought this power meter to keep track of how much electricity my appliances use, and it has been very helpful. The screen is bright and easy to read, even in low light. I like that it shows different measurements like watts, volts, amps, and energy usage, so I can get a clear picture of power consumption. The controls are simple, and switching between the display modes is quick. It feels well made, works accurately, and has been a useful tool for lowering energy waste around my home.
