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
Description
WARNING！！！ 1. DO NOT use in wet environment. 2. DO NOT connect the power meter to a multi-plug outlet to measure multiple electrical appliances at the same time, in case the total power exceeds the threshold of 1800W and cause a short circuit. NOTICE: WHEN POWER SWITCHED OFF AND BACK ON, IF THE POWER METER TURNS "0", IT MAY BECAUSE THE TESTING TIME IS LESS THAN 1 HOUR, OR TOTAL KWH LESS THAN 0.1 KWH. THAT'S WHY NO DATA SAVED.

Does well what it’s supposed to do! Needed to ensure a voltage sensitive appliance was receiving adequate voltage. It has other useful functions too that I might utilize in the future but this is what I purchased it for. Good price too, and a quality product.

Great meter for know how many watts a appliance is using and a great addition is it adds up how much the appliance cost to run also , a great feature as I use it for plant experiments, I need to know wattage and cost of a grow from seed to harvest , this is a spectacular product for these calculations

Easy to use, the one-page (double sided) sheet is descriptive and helpful. When used with an outlet where both are used, you can run into a bit of a problem. The unit "intrudes" onto the second outlet's path. Which means if a two prong plug is used in the second outlet, it is likely that it can be inserted with no problem. However, a three-prong lug may be too "thick" to fully mate (see images). And if a USB dongle or power-brick is installed in the second outlet (see images), it is unlikely that all can be plugged in successfully. It can only be plugged into the top outlet without fully masking the lower outlet. The manual is good at hinting at tricks to be used for properly measuring an appliance's power usage, like commenting that the refrigeration compressor being on will engage power measurements, while hinting that when the device is quiescent, no power is consumed, and the clock isn't running. The display is bright and easy to read, even at oblique angles and in bright, indirect sunlight. The reset tool provided needs to have a clip or compartment in which it can be stored. I will guarantee you will lose this; I'm going to attach it with a string through a hole I'll drill in the tool. I think you can safely use a ballpoint pen, although the mfg does not recommend this. My usage of these devices will be to measure the short and long term power consumption of various devices in order to properly size UPS-style battery backups for medical devices. I am pleased with them so far. I wish I could give a 4.8 or 4.9 because of the limitations I've outlined here. Not as bad as a 4, and not perfect either.

I use an Emporia power meter (https://www.amazon.com/dp/B08CJGPHL9 ) to monitor whole-home and per-circuit power usage, but this product really allows me to focus on a single device. The display is clear and easy to read, and the values if displays are just the ones that I want to see. The "Function" button lets you cycle through the different display modes (e.g., Power, Voltage, Amps), and works exactly as you'd expect. Some display modes have a counter feature, which is also very nice - a graph would have been a nice add-on, but perhaps one wouldn't expect it for the price, which I hasten to reiterate is very competitive. The unit is solidly-made, and has no trouble working with relatively heavy-current items, such as a 1500W kettle, shown in the pics. My only complaints about it are the directed to the user interface. They managed to find room enough to put four buttons on the front of the thing, but to clear/reset the counter display you have to push "Function" and "Up" simultaneously. I may be some sort of weirdo special case, but "Function" (mode selection) and Clear are the only operations I'll ever care about, having set up the small set of configuration options. I expect that I'll only use it once a month or so, and I'll never remember the mysterious chord to reset the counter. I expect I'll write the cheat code on the unit with a sharpie!

I feel price informs value and try to include the price paid in all my reviews. I highly recommend everyone do the same. In this case, I paid $19.34 for the 2-pack on 11/4/23. If you are reading reviews of power meters, you already know why you want one. This particular model is a good successor to the old Kill-A-Watt meters. The KW brand still exists, but have priced themselves out of the game. Pros: These meters have a large, bright display, easy controls, and are (within my ability to test, which makes them fine for the home gamer) very accurate. These will track all the usual real-time info: Volts/PF/Watts/Amps/Hz etc. And they have a nice cumulative power consumption option that is missing on some of the other lower cost meters. This feature is great to find how much item x is using over a day or a week, etc. I use them to test battery capacity for my solar system and they work fantastically without the need for uni-taskers equipment like a coulomb meter. Cons'ish: Version - Make sure you get the model that says "Updated". There is an identical looking model that doesn't have a backlight, nor does it have the ability to reset the watts over time count without a "press the button in the hole with a pen" method. If the pictures shows the blue backlight, you are all good, but I find the old version pretty much useless and didn't' realize till too late to return. Size - These are pretty big. Lots of scenarios where they will block the other outlet, etc. Easy enough to work around, but worth noting. Summary - I've got several of these and couldn't be happier. I use them at home and work and have never had any trouble with them. They handle 15 amp loads without any issue as well. I would definitely recommend when on sale around $10/per.

Works great, wish it had a memory or 2. It accumulated power over several days. That's exactly what I wanted.

I've seen this meter used on multiple YouTube channels on power station. I thought was a very useful and since I am a tech nerd/geek it wouldn't hurt to have one of these. Quality appears great. Very user friendly with several features/modes to navigate through. The backlight is a plus for us hard-to-see folks :-).

I give this 5 stars because it does everything in its manufacturers description! I am on oxygen machine 24/7 and was surprised that my Electric O2 concentrator ran at a much lower wattage than I expected. My fridge, on the other hand, sucks. NOT LOL !
