Features
- Various Monitoring Parameters: The power meter plug can monitor the power (W), energy (kWh), volts, amps, hertz, power factor, cost, minimum and maximum power (W), cumulative days and time of your appliances. By switching 7 display modes, you can easily know the various parameters while the appliance is working. The home energy monitor can also calculate and display how much power your appliance uses and how much electricity bill it cost in cumulative time.
- Upgraded LCD display: With large screen size 2.36 inch x 1.85 inch, clearer monitor backlit, our electrical usage monitor can display the data clearer and more visible no matter day or night. 180full wide viewing angles is great for reading and recording the data in any angles. No need to stand on the front of the display and bend over to read the numbers.
- Adjustable Backlight Time: Our upgraded watt meter has 5 options of backlight time. The default backlight time duration is 10 minutes(bL-0). If you want to change the backlight time, you can press and hold "UP" and "DOWN" button at the same time to enter backlight time setting, then press "UP" and "DOWN" to select the backlight time (bL-0 =10 minutes, bL-1=1 hour, bL-2=4 hours, bL-3=8 hours, bL-4=always on), finally press the "COST" to save the backlight time settings.
- Overload protection: When the power of the appliance exceeds the overload power, the LCD will display OVERLOAD to warn the user. All the buttons will quit working and can only be workable when you lower or remove the load power. The default overload power is 3680W and is adjustable from 0 to 3680W. In general, you need to set the overload power to 1800W before using. Just press the "function" button for more than 3 seconds to enter the setting.
- Data Memory Function: The wattage meter will record your power consumption data when you remove it from socket, or remove appliances from the electricity monitor. You can directly see the last data when you use it next time. This function can also automatically save the data when there is a sudden power failure.
- Monitor Your Energy Usage:Our watt meter power analyzer lets you track electricity consumption and manage power usage to help save on bills. It works as a voltage, kilowatt, current, and electricity meter. If you have any questions about your meter socket, feel free to contact us.

I had always wanted one of these to help understand power usage through my home. This one has good good features, works well and is easy to read at a distance. All you do is plug it in and then plug in whatever device you're interested in getting insight into. Quick and easy to use! I've now gone through my home checking to see what the power usage is of various devices, such as our trusty coffee maker, lamps, TV, Internet and other such things. All this in preparation for knowing just how much power we'll need in a power loss scenario, so we can adaquately plan for a solar generator. If you're interested in finding out where the energy vampires are in your home, this is your tool!

Got a pair of these to use for monitoring/measuring wattage consumption for various appliances and devices in our house, prior to having a generator switch installed in our house. In order to determine the branches to power through the generator switch box and how much each branch will consume for the total wattage and capacity of our generator, these two plug in monitors are proving to be worth their weight in gold! The display is crisp, the text sharp and easy to read and the backlight display, when needed, is a huge plus. The assorted options available for settings and view of volts, amps, watts, watt-hours, electrical cost factor, etc, are also excellent. Delighted with these and I might be ordering one more to monitor another major appliance we'd be using during a power-outage and generator use. My only regret is not being able to monitor 240 volt appliances like our oven/range and dryer, but, I'm searching for one specifically for this and if they're available, I'll consider getting one of those as well. As for these wattage monitors, delighted with their performance and the reasonable cost per unit. 5 Stars all around!

Simple to use, works as advertised, and delivered as promised. I now know how much load the Christmas lights outside are adding to a recently added landscape lighting system. I now have peace of mind.

Nice, inexpensive device. Very useful. 4-5 stars except for these negatives: 1. Some controls and settings are virtually impossible to access unless you have the instructions. Not intuitive at all. 2. If you want to know how much power your device uses in an hour, day, week, month, etc you must write down when you plug it in and when you unplug it. The meter will not give you that information. It only tells you how many minutes, hours, days, etc. your device is running. e.g. If your fridge, AC, or heater cycles on and off, it will tell you how many minutes, hours, days, it's been running, not how many days the appliance has been plugged in. You might have it plugged in for a week and the meter might say "3 days" because that's how long your appliance ran since you plugged it in. I've been using two of these every day for a couple months. I love the large bright blue display. You can have the screen on all the time or turn it off. By default the screen turns off after 10 minutes. Good purchase if you want to measure electricity usage.

Power meter works better than expected. Love the features including the ability to set your local cost of electricity my kWh enabling you to quickly see "How much is this thing costing me!".

The Mecheer Upgraded Power Meter is one of many available on the market. I own three power meters—one for each of my homes—and find them very useful, whether for reducing energy consumption or checking if an electronic device is actually working and drawing power. When I bought my first meter years ago, I opted for an expensive model. The second was mid-priced, and this time I decided to try a budget option—the Mecheer currently sells at about $12 on Amazon. Interestingly, all three perform the same, and I haven’t noticed any meaningful differences. While I haven’t yet tested this model’s long-term durability, it works as advertised and seems reliable. I’d certainly recommend it for home or DIY use. Disclaimer: I am a regular paying customer and did not receive any incentives from the seller or manufacturer.

This watt meter is fantastic! I used it to track down high electricity usage in my home, and it was incredibly helpful. The display is easy to read, setup is simple, and it provides accurate measurements that helped me identify which appliances were using the most power. It’s a must-have for anyone looking to monitor and reduce their energy consumption. Highly recommended!

Simple to use and gives you lots of data would recommend this product. Purchased this item to tell me how many amps a fridge was drawing. You can use this item for many things like checking the power draw when your TV is turned off.
