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

This unit does everything I need. It is well constructed, easy to program and the digital readout is easy to read. Shipping was fast and cost was very competitive. I rate this a GOOD BUY.

Worked great. I was able to see how much energy space heaters and other appliances were using, some of which were surprising. Definitely worth buying.

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.

Item is versatile and easy to use, and overall I’m satisfied with it. However, one star was removed because the plug itself is kind of large, so you cannot plug something into the other outlet when using it.

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.

The upgraded watt meter power meter plug works exactly as advertised. It is plug and play very responsive and accurate. and I have used it to gauge the draw on many of my appliances. It has helped me track down the source of many tripped breakers since I bought it. it's already paid for itself in my time saved and I consider it very useful. I have had my computer plugged into it and it has been durable enough to handle long-term draw under heavy load

Works great! Using it to monitor my car's battery maintainer / trickle charger in an effort to see if I could use it via a power station. It's giving me all the info I need.

Excellent product! Fast readings of watts, voltage, etc. Very helpful to see power usage of appliances to see where I can reduce power costs.

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.

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!

They work perfectly.

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.

Works as expected and good price , seems accurate. Reacts quick enough on appliance start up.
