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.

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.

Inexpensive & works well. Nice to know what things draw for power

Works very well, easy to use. I use it with my midea inverter air conditioners to monitor power usage to make sure I don't overload my generator.

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!

This upgraded watt power meter plug is a very useful tool for checking how much electricity different appliances and devices are using. It is easy to plug in and gives helpful readings for power consumption, voltage, and energy usage. I especially like it because it helps me monitor how much power certain items are using with my solar power system. It makes it easier to see which appliances are pulling the most electricity, so I can better understand my usage and manage my solar and battery power more efficiently. Overall, this is a handy electrical usage monitor for anyone who wants to track power use, save energy, or get a better idea of what devices are costing to run.

I bought this primarily to monitor power draw from an inverter I bought that didn't have a built in meter. If you know anything about inverters, the modified sine wave (square wave) type will read low voltage on a non-true RMS meter. This item actually reads true RMS which is a big plus. This isn't a lab quality instrument but, if you want an idea of how much power an appliance uses, it's a pretty good tool. Display is easy to read. Backlight is a nice feature. Only issue I have, if your trying to set some of the functions on it you have to plug it in. That means you're down on the floor or in another awkward position to set it. Would be nice if it had even a small battery that would charge when you plug it in for a short time and allow you to unplug it to set it. I made a short 12 gauge extension cord to use with mine. Overall, I'm very happy with this unit.

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

The product is pretty good. It helped me figure out which devices were using the most energy, so I could adjust my energy usage by unplugging them and replacing them with ones that don't use as much power. It's a great product for anyone who likes to keep everything under control.
