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:
The consumption and time will NOT be measured and counted when: your device is in standby or not working;the rated power of your device is smaller than 0.5 watt, but energy consumption is always measured since the device was plugged in. What data will be saved? Electricity quantity, cost, electricity p rice, cumulative time. (But NOT save current, voltage, power, power factors)You can access to Mode 7 directly by pressing the button “COST”.Press any buttons to wake up the backlight after it automatically turns off (Backlight time is adjustable).If there is an abnormal display or no response, please reset the electric meter by pressing the RESET button.
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.
The power of electrical appliances can not exceed 1800W.HOW TO RESET: If you only want to clear the cumulative data (Electricity quantity, cumulative cost, cumulative time) and keep the electricity p rice setting, just press button “FUNCTION” and “UP” at the same time over 3 seconds to quickly clear the data.If you want to reset all the settings, you can press the reset button with the reset tool. Don’t use a needle because it may cause the button to get stuck in the device. HOW TO SET THE BACKLIGHT TIME: Press and hold “UP” and “DOWN” button at the same time to enter backlight time setting. Now “bL-0” is displayed on the LCD and flashes for 10 seconds.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).Press the “COST” to save the backlight time settings.When you don’t want the backlight on, press the “DOWN” button to turn off the backlight manually.You can also press any button to turn on the backlight again.

Works well, understand its limits
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.

Great tool to monitor power usage and electrical performance.
Great tool to monitor power usage and electrical performance.This watt meter is excellent for tracking power consumption, voltage, current demand, and power factor in real time. It’s very useful if you want to run your own experiments and analyze what’s actually happening with your electrical load rather than guessing. The readings are clear and consistent, making it easy to understand energy usage and efficiency. A solid choice for anyone interested in monitoring and analyzing power behavior at home or in the lab.

Excellent right out of the box (even with weird UI); great value
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!

These are Great! You won’t regret buying them.
These things are AWESOME! I have 1 for each of my 3D Printers (see pics). They really help with determining the peak wattage, cost of electricity, etc. I would buy again without hesitation. I would recommend to anyone who has a need … or who is just curious about how much a device costs to run.Did I mention that these are EASY to configure?! The instructions are clear and easy to follow.

Neat tool
Works well. I bought it to monitor my coffee bean roaster. Turns out no worries but good to see and know for sure. I haven’t done it yet but I intend to out this online with an older freezer. I’d like to see if I am paying more for electric to justify replacing.

Good basic tool to check power use
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.

Ich habe etwa 9 Energiemessgeräte verschiedener Hersteller. Alle haben den Nachteil, dass die Displays nur aus einem bestimmten Blickwinkel gut abzulesen sind. Oft sind Steckdosen in der Küche, Wohnzimmer, oder hinter Waschmaschinen/Trocknern in Hüfthöhe oder einige Zentimeter über Fußleisten am Boden angebracht. Aus Sichthöhe sind diese Displays nicht oder kaum abzulesen. Ich habe auch Meßgeräte mit obenliegendem Display, aber ich muss nahe herantreten, um die Daten ablesen zu können. Normale frontseitig angebrachte Displays sind aus Sichthöhe meistens nur mittels Taschenlampe abzulesen. Deshalb suchte ich lange Zeit nach einem Meßgerät mit beleuchtetem Display. Diese gibt es, allerdings schaltet sich die Hintergrundbeleuchtung in kürzester Zeit von selbst ab. Das ist nervig, z. B. wenn ich Stromschwankungen beobachten oder Daten notieren möchte. Dieses Energiemessgerät für günstige 12€ bietet genau das, was ich lange gesucht hatte. Das Display ist sehr groß, alle Daten sehr gut ablesbar, allerdings nur bei aktiver Hintergrundbeleuchtung. Ohne Beleuchtung sind die Daten kaum zu erkennen. Mein Meßgerät entspricht nicht der (unbeleuchteten) Abbildung im Angebot. Das Display ist dunkelblau mit schwarzem Rahmen und die weißen Ziffern sind bei ausgeschalteter Beleuchtung kaum zu erkennen.Allerdings schaltet sich bei leichtem Druck auf eine der vier Tasten das hervorragend beleuchtete Display ein und alle Daten können auch aus weiter Entfernung klar und ohne Stress abgelesen werden. Und das für ganze 10 Minuten. Glücklicherweise stimmt dies nicht mit der Bedienungsanleitung überein, hier soll die Hintergrundbeleuchtung nur 30 Sekunden aktiviert sein. In diesem Fall hätte ich das Messgerät zurück gegeben. Meines leuchtet aber nicht 30, sondern volle 600 Sekunden. Die Messungen sind genau, mit den Funktionstasten kann ich alle wichtigen Messwerte durchblättern und die Kosten je kwh einstellen. Das Gerät zeigt Stromverbräuche ab 0,3 W an, erfasst somit auch die kleinen Standbyverbräuche. Ministröme unter 0,3 W werden mit 0,0W angezeigt. Das ist bei den meisten Energiemessgeräten ebenso der Fall. Für diese Miniverbräuche habe ich ein Meßgerät, welches ab 0,01 W misst. Das kann ich aber nur gebückt und mit Taschenlampe ablesen.Dieses Energiemessgerät hat keine Speicherbatterie, löscht also alle Daten (außer dem eingestellten Strompreis), wenn es aus der Steckdose entnommen wird. Dafür habe ich aber Meßgeräte mit Speicher.Alles in allem aber ist dieses Energiemessgerät für alle Normalnutzer, die ein sehr gut ablesbares Messgerät (wenn hintergrundbeleuchtet) mit einem hervorragenden Preis – Leistungsverhältnis suchen, sehr empfehlenswert. Mit seinem dunkelblauen, lange beleuchteten Display ist es auch ein ausgesprochen schönes Gerät.

Very nice meter. Easy to read and work with. Does everything except make the coffee 🙂

Meter appears to work well, but the build quality isn’t great. Removing the thin clear film from the display seemed to almost pull the display out of the casing.

I have only had the meter for a week or so. We bought it to replace a much older unit (different model and manufacturer) that had mysteriously become very inaccurate. Everything so far has been quite pleasingly simple. The massive advantage over the old device is that this meter will integrate the power reading over a period of time to give total energy consumed in kWh. The old meter would only give current power consumption. If the equipment under test has fluctuating demand (e.g. anything with a temperature controlled heater or pump), it is very difficult to get a good idea of energy usage without this feature.I have compared the voltage reading against an accurate digital voltmeter and get agreement with 0.5%. I cannot be sure the current range is as accurate, because I could only compare it with a current clamp working at the lower end of its range, but the readings were consistent so I have no reason to doubt the plug-in meter. I do find it strange that nowhere on the unit is there any mention of the manufacturer or model number, although there is a label giving the electrical specifications.The instructions are very brief, as mentioned elsewhere, but then they’ll get lost anyway! It is obvious how to operate (except I have not used the cost function. I am perfectly capable of multiplying the kWh buy the charge rate using a calculator). The most important point to remember ( I will probably write it on the unit) is that you can clear the readings and restart the timer by holding don the “FUNCTION” and “UP” buttons for a few seconds. For us it is really useful that we can clear the readings without having to interrupt power to the equipment for which we were measuring the power consumption. I have not had any need to press the “RESET” button yet.The price was very keen and it’s doing a really good job for us so far. I have no reason not to give it 5 stars
