Upgraded Watt Power Meter Plug Home Electrical Usage Monitor Consumption, Energy Voltage Amps Kill Tester with Backlight, Overload Protection, 7 Modes Display

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

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

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

I am using this for UPS installations. I can see in real time the wattage of the load AND I can leave this on site for a week and then get a read on the highest wattage peak. Very useful for selecting a UPS. The peak watt value is great. If you want to know for example your washing machines highest wattage, you would have to stand there through all the wash cycles and keep an eye on the meter. Instead, this thing will hold the value for you. The game changer between this one and the others is the select able backlight times. The display is large enough that I can read the wattage from across the room 8 feet away. It is bright and clear enough to see at night and when the sun is shining directly on it as well. It is easy to read from any angle. Take a look at the photos and see the stand I made. So why 4 stars? No fault of the unit, and it is, I guess, 5 stars as it holds up to all it's advertisement. I just see some features that seem obviously missing to me, that I would like. It would be nice to have the peak watts and real time watts in the same window display. It would be nice to have a small clip on the side or rear to hold the reset tool it comes with. The big one here...In the 3 sections display, it would be nice if you could set the three individual readings to what you want. For example, I would have it display real time watts, peak wattage, and real time voltage in the three sections display. Anyway, it is still awesome!

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 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 !

Worked like it should and very easy to use, very much plug and play and the menus are easy to understand.

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.

I had no idea a tool like this existed, but it takes the guesswork out of wondering why your electricity bill is so high. In this video, I'm using it to measure the current draw of a pool heater. I was in a hurry to set the heater up and tried buying a tool like this at the store, but I could not find one at any hardware store near me.

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.

mide muy exacto el consumo de electricidad

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.

Presto corriente a mi vecino y este me permite de ver exactamente lo que esta utilizando, es perfecto.
