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

Does well what it’s supposed to do! Needed to ensure a voltage sensitive appliance was receiving adequate voltage. It has other useful functions too that I might utilize in the future but this is what I purchased it for. Good price too, and a quality product.

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.

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!

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

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.

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

This is the most useful electrical meter I have ever owned. It provides every electrical measurement one would need for typical household use and is very easy to use

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.

I'm really impressed with this power watt meter. I needed to know how much wattage my brand new desktop computer was using but mainly on the start up and this power meter monitors and shows me that type of information. Here is what the unit will display, the time since connected, the total amount of wattage since connected, the current wall voltage with frequency, the current amperage being drawn plus the power factor, the lowest wattage reading, the highest wattage reading and the total cost for running item. In order for the last one to work, I must enter the price it costs me per kilowatt hour which I got off my hydro bill. I like that this unit has two different resets, a factory reset and a soft reset which will only remove the accumulated data like time since connected, low and high readings. The unit comes with two reset tools, these are for the factor reset but any small blunt object will work as a reset tool. The soft reset is done by pressing two buttons on the front panel at the same time. I also like that I can change how long the screen backlight stays on. If I want to see how much energy my PC uses for the month, then I can set the backlight to turn off quickly but if I'm doing readings every few minutes then I can leave the screen on longer. My options are 10 minutes, 1 hour, 4 hours, 8 hours and stay on always. Since my GPS device doesn't say when it is fully charged, I connect my GPS thru the power meter. When the power meter wattage starts to decrease then I know my GPS is almost charged. This power meter also came in very handy as it detected that I was using a USB A to C cable that didn't have the ability to pass more than 2.5 watts. When charging some items, their charge time went from 4 hours to 10 hours so now thanks to the power meter, I checked every USB cable and have rated the cables to their wattage level. Now, I can grab the right cable when charging a device. This power watt meter is outstanding and very useful.

1. It showed me that the TAPO P110 smart plugs I use to shut everything off (eg all the computer gear at night) are not super accurate. EG, Testing a fridge over 24 days, TAPO 23.7kw. The Blue beast, 24.7Kw (TAPO 1.06 Kw out) TAPO plugs use only a few watts and are Wi-Fi linked to an APP on my mobile phone. The APP has just been updated and seems to be more accurate now, and you can add your Kw/£ unit. However there have been some changes to how it displays readings which are taking some getting used to. 2. BLUE You CAN reset the values, by pressing FUNC and UP together for a few seconds. Rather than fiddling with the 'reset' tiny button. Partway through test now, so cannot double check, but I think it keeps price, clears rest. If not, adding price again is no big thing. 3. Bit of a pain that you have to press FUNC to get it to light up, which shifts it to the next page, then you have to cycle through the pages again to get to 'Using NOW' which includes, top, 'run time' (which is the amount of time the item has been using more than 2 watts, ie actual working hours total.) Using Watts 'now', middle, and at bottom, COST 'up to NOW'. You learn fast this page, is right after the page with HI written at the bottom. 4. I can read the screen, sat on top of the counter, even when it is in 'dark' mode with the backlight off. So I stopped having to cycle through all to get the backlight on. 5. Right now, I am testing two fridge/freezers at the same time. A on a TAPO, B on BLUE. Fridge A is old, old, and built into a kitchen as an undercounter fridge freezer, H86,W54,D60. Ave 0.9 Kw a day. My first set of tests on fridge A alone was with a TAPO AND the BLUE. Running the 2 fridge comparison A has just a TAPO (updated APP) on, and the BLUE is on the B, other fridge. Part of the reason A is using so much, apart from being old and inefficient, is that it is jammed in there with no ventilation. It is in effect, heating itself, in a box then having to cool itself back down. The pump peaks at 100w on start up, down to 71w just before it shuts off and it cycles for an hour at a time. Then has a rest, while it soaks in all the boxed in heat, for a bit over an hour... Then off we go again. 24 hour test, runtime 11 hours. Temp varies between 7.4c and 2,6c during this insanity. NOW, I only know about the runtime and pump peak specifics because the TAPO smart plug (Updated APP) gave me that info as a graph (past 24 hours, Power). I had to work out runtime from APP, (APP not clear on this, whereas Blue is specific). BLUE will tell you it peaks(HI)at something like 1560W, because it is so sensitive and for a split second that is the load watts to get the pump to start, but it doesn't really help in this situation. But BLUE will give you a very accurate runtime, from start, to NOW. Not, each day and when, which the APP will. So the best way to use the BLUE is run an appliance for an hour, or, a day (24hours, eg 3pm to 3pm). Or you can just plug something in and see what it uses and take your shoes and socks off and do some maths. 6. Fridge B, Running on just BLUE, this fridge (16 year old, Whirlpool, class A before the codes changed) I dug out of storage. Stood on the kitchen in free air. Uses ave 0.35 Kw a day. Peaks (I had to watch for this when I heard it turn on) 69w and tails to 51w just before it shuts off. Runtime (accurate from BLUE), 6 hours a day. Temp max 5.8c, Min 3.9c. SO the question becomes, (and if you read this far, thank you) is the Blue Beast worth having? ABSOLUTELY! You can very quickly find out what an item, or set of on the same 4way, appliance uses, right at that moment or over a period of time. And for a fridge, or washing machine < 60'C, 2h40m, 1.44Kw, 48p at 33p/unit> (as long as you can get to the plug and plug it in) you can gather enough data to decide to rip out an old built in fridge and put the 16 year old one in instead.... and save £80 a year.
