    Very legible, easy-to-use, close to pricier Kill-a-Watt machine's measurements, nice design. Photo shows it plugged into our power station, showing the same amount of power output as the Watt meter indicated flowing to an electric radiator set on level 1 (~ 560 Watts). Can show Watts, Amps, KW used during a period of time. Illumination is a nice color temperature, display has large digits that are quite legible even across the room.

    Inexpensive and it works great.

    Reviewed in the United States on November 22, 2024

    Color: GreySize: 1 PackVerified Purchase

    First off, I own multiple Klein and Fluke testers. I still use these for multiple applications. Each of these cost in the excess of $ 100.00. I always need to remove their batteries so that the batteries don't leak and destroy the tool. It's a "best practice" thing.
    Here's the cool things about this tool, it's inexpensive and it doesn't take batteries. You plug into a socket, and it's powered automatically. I checked it for accuracy against both my Klein multimeter, Klein socket tester, and Fluke inductive testers. It was dead on for all measurements: Volts, Amps, Watts, etc.
    Here's the question: Why would I use this if I wave the other meters? Well. this is quick and easy, and I hate reinstalling batteries in each of the other devices.
    If I have multiple circuits to check or troubleshoot, I'll beak out the Klein and Fluke tools, but if I only have a couple of things to check or I didn't have multiple hundreds of dollars to spend, this tool is a very reasonable substitute.
    The only drawback that i can see, is that this tester resets back to W (watts) every time it's unplugged. It's a small annoyance to cycle to one of the other measurements. It only takes a few seconds, but it's an annoyance.
    Note: The directions are a little weak. To cycle what is being measured, you hold down the (M) button for about 5 seconds, the screen will flash, then tap the (M) button again until you see the proper field you want to be measured. It only takes a few seconds.
    I would definitely recommend this tool.

    This works well and isn't intrusive. Easy setup too. Just find what you pay for electricity, per KW/h, enter it and it's ready to go.

    The only thing, which I hope they'll address is that the LED backlight is wsy too bright with no way to adjust the brightness without adding a modification on the PCB itself.

    Other than that, very nice product at a very reasonable price.

    Präziser und benutzerfreundlicher Stromverbrauchsmesser – Ideal zur Überwachung des Stromverbrauchs!

    Reviewed in Germany on August 19, 2024

    Verified Purchase

    Der MECHEER JK-PM01 Stromverbrauchsmesser hat sich als ein äußerst nützliches Werkzeug zur Überwachung des Energieverbrauchs in meinem Haushalt erwiesen. Dieses Gerät bietet eine genaue Messung des Stromverbrauchs und ist dabei einfach zu bedienen, was es zu einem unverzichtbaren Hilfsmittel für alle macht, die ihre Energiekosten besser kontrollieren möchten.

    Die Installation des Stromverbrauchsmessers ist kinderleicht. Man steckt ihn einfach in eine Steckdose und schließt das gewünschte Elektrogerät an. Das große, gut ablesbare Display zeigt sofort den aktuellen Stromverbrauch an. Das Display ist beleuchtet, was die Ablesbarkeit auch bei schlechten Lichtverhältnissen erleichtert.

    Der MECHEER JK-PM01 bietet eine Vielzahl nützlicher Funktionen. Neben dem aktuellen Stromverbrauch in Watt zeigt das Gerät auch die kumulierten Kilowattstunden (kWh) über einen bestimmten Zeitraum an. Zudem können die Kosten berechnet werden, indem man den aktuellen Strompreis eingibt. Dies ist besonders hilfreich, um die Energiekosten für bestimmte Geräte genau zu ermitteln.

    Ein weiteres nützliches Feature ist die Möglichkeit, den Stromverbrauch über einen längeren Zeitraum zu überwachen. Der Stromverbrauchsmesser speichert die Daten und gibt einen Überblick über den durchschnittlichen Verbrauch, was hilft, ineffiziente Geräte oder unnötige Stromfresser im Haushalt zu identifizieren.

    Die Genauigkeit des Geräts ist beeindruckend. Selbst bei Geräten mit geringem Stromverbrauch liefert der MECHEER JK-PM01 präzise Messwerte, was es ideal für die Überwachung aller Arten von Haushaltsgeräten macht – von großen Geräten wie Kühlschränken und Waschmaschinen bis hin zu kleineren Elektrogeräten.

    Das Gerät ist zudem kompakt und nimmt nicht viel Platz in Anspruch, was es einfach macht, es an verschiedenen Steckdosen in der Wohnung zu verwenden. Es ist robust gebaut und fühlt sich langlebig an, was für den täglichen Gebrauch wichtig ist.

    Insgesamt bin ich mit dem MECHEER JK-PM01 Stromverbrauchsmesser äußerst zufrieden. Er bietet eine präzise, benutzerfreundliche und kosteneffiziente Möglichkeit, den Energieverbrauch im Haushalt zu überwachen. Für alle, die ihre Stromkosten besser kontrollieren und Energie sparen möchten, ist dieses Gerät eine klare Empfehlung. Klare 5 Sterne!

    As described, works great for my use

    Reviewed in Germany on April 18, 2024

    Verified Purchase

    We are loving abroad in Germany and brought along some 115v appliances. To power them, we got a couple of voltage transformers, which many told us to use sparingly due to their high consumption, especially when the transformer is idle. I wanted to see how they actually performed, not how others claimed they would. So, I got this. It reads voltage, watts, and kwh, and also times the load. This thing is pretty cool. Not only did it do what I wanted, but I could measure use over time. Power here is expensive, so I wanted to know if it would be less expensive to buy and run 240v appliances. For my case, I think the answer is "no", as the appliances are used for a few minutes a day and the meter verified that the transformer only adds about 26 watts to the usage and pulls the same 26 watts with no load. I expect it would get worse as it warmed up, but that's not likely here and we can shut ours off when not in use. That's another thing we were warned of, that the transformer would pull power even switched off. In our case, at least, that is untrue. Ours pull 0 watts turned off.

    Back to the meter. It's simple to use, and tells me the information that I want to know. The display is simple, logical, back-lit when plugged in to a powered outlet. It works great. Delivery was fast and it was packaged well.

Product Summary: Upgraded Watt Meter Power Meter Plug Home Energy Monitor Electricity Usage Monitor, Electrical Usage Monitor, Energy Voltage Amps Meter Tester with Backlight, Overload Protection, 8 Display Modes

From MECHEER
Multi-function power monitor: Our electric usage monitor can monitor the power (W), electricity(kWh), voltage(V), frequency(Hz), current(A), power factor(PF), unit price($/kWh), total cost($) of your appliances. By switching 8 display modes, you can easily know the various parameters while the appliance is working. The “electricity” mode can calculate and display how much power your appliance uses. And the “total cost” mode will show how much electricity bill it cost in cumulative time
Overload protection: When the loading power of the appliance is over the default overload threshold 1800W, the whole display with backlight and the word “OVERLOAD” will keep flashing to warn the users. Please turn off the appliance for safety concern
Premium Material: The whole body of our energy meter is made of high-quality ABS material. It makes our home electricity usage monitor more long lasting, fireproof and anti-drop. The standard US socket and plug is suitable for all US standard appliances
Backlight Display: With white backlight and black words, the LCD display of our home power monitor can display the data clearer and help you to read the data easier no matter day or night. The backlight will only lights up when the device is connected to AC power. If no button is pressed, the backlight turns off automatically after 10 minutes. You can also press the “UP” button to turn off the backlight manually, and press any button to turn on backlight again
Easy to reset: No reset tool needed, our appliance power usage meter is easy to reset. You can press the “M” button for 5 seconds directly to reset the device. After reset, all cumulative data (electricity quantity, cost) will be cleared, and all settings will be restored to factory settings
Data Memory Function: The watt meter plug in will record your power consumption data when you remove it from socket, or remove appliances from the electricity monitor. All setting data and cumulative data(electricity quantity, cost, unit price) will be saved. You can directly see the last data when you use it next time(NOT including current, voltage, power, power factors). This function can also automatically save the data when there is a sudden power failure
