Power Meter Energy Monitor Plug, Besvic 13A Electricity Usage Power Consumption Monitor Socket with 7 Monitoring Modes, Overload Warning, Amp Wattage Volt Meter Analyzer (2Pack)

I have ThermPro temp/humidity measurer and these 2 match precisely the temprature read, so I know they are accurate.Very easy to set up. it has START temp - i.e. if the temprature is THIS or BELOW it will activate... and STOP so if the temprature is THIS or ABOVE, it will stop.You can also reverse START/STOP to make it cool the room, it AUTOMATICALLY SWAPS into COOLING mode, so you don't need to do anything, other than set desired tempratures.Super good and Accurate.ps if you are using your hands to set it up and touching the MEASURER, you need to give it couple of seconds (like 30 or so) for it to settle and the metal to cool down, then you get accurate reading. Cause I was super angry, when I saw that it doesn't measure correctly, but then I realised it was ME TOUCHING THE METAL, so you need to wait till it cools down and stabilises. ITS SUPER ACCURATE, I can vouch for it.

A good product, great for checking electricity running costs for my many gadgets. On the negative side, every time I am using it for a different appliance the cost per kilowatt hour has to be reprogrammed, it would be more convenient to be able to clear the data but keep the cost constant. However this is a minor irritation and on the whole I am pleased with the items

I had an old plug-in energy monitor which I have never been able to use properly, The instructions were difficult to read and I could never get it to work. It has inputs for different rates at different times on different days and other menu options I could not fathom, so I bought two of these and another of a different make to see if one was easier to use than the other. The other was a Decdeal energy Monitor and was slightly more expensive than one of these which are branded besvic. I found both monitor types easy to use. you just have to press the COST button for four seconds and it starts flashing for you to input your electricity cost in £ per kWh. I didn't bother with any other inputs, because I just wanted to measure electricity consumption for 24 hours for several different devices. After 24 hours, all three meters gave a cost in £ so I was able to identify which appliances used most electricity and which used very little. I found the appliances on standby and mobile phone chargers used very little, whilst my high-end gaming PC with three monitors costs about £0.50 per day and the tropical fish tank about the same. One of my fridge freezers used £0.48 per day but the other used only £0.22 per day (it is newer). Negative feedback comments around Electricity Monitors mostly centre around an unreadable display and inaccurate measurements. I have to say that a bright, illuminated display would be worth having, but I never had any trouble reading the display on these monitors, although you have to be within two feet and looking fairly square on. In terms of accuracy, when measuring same device, over three days, I found that both besvic meters recorded £0.50 and the Decdeal showed £0.48, so there was not as much variation as I had feared. This does not prove they are giving an absolute accurate figure, but at least they were consistent. In terms of power measurement, the meters showed about 100W of power consumption for my PC on it's own, and 250W consumption with the three monitors turned on as well. That is equivalent to two and a half 100W light bulbs which seems about right to me, so I think they are reasonably accurate. Overall I found these easy to set up and use. With the recent astronomical increase in the price of electricity I think these are worth buying to help reduce energy costs by becoming more aware of the high cost appliances in your household.

One is working fine, the other one looks to be faulty- constantly shows overload from the day one and can't be set at all.

Fantastic device best to use a torch to read display- no issue for meUsing mode 2 top display shows time attached device is drawing power middle gives cumulative KWh third display starts at 0 and once top display reaches 24 it resets to 0 and bottom display moves to 1 - fantasticDiscovered that my old chest freezer was using over 2 units per day replacement uses 0.6My 65” OLED TV hooked up to SONY Hi Fi system was using 1 unit a day in standby and 4 units when on for 15 hours - company for our dog !Fitting a standby saver and using TV sound reduced consumption to around 1 unit per dayWine cooler now used as wine store saving 0.6 units per dayNew 32” TV on order which uses a fraction of the energy for early morning viewing in place of 65” which is excellent for films etcCurrently reviewing consideration of solar panels to reduce our consumption- no longer looking a sensible option !If would definitely recommend these units having had to return an alternative model from a different company which was dead on arrival

I bought these to see what sort of power consumption my appliances use. The problem primarily with these is that the screen is very hard to see at any other angle other than directly on. You might think this is ok, but plugs are primarily in awkward places, for example behind the TV or near the floor, in these cases you need to get your eyes straight and level with the screen to take a reading in normal light. I did find that if a shon a torch in it, I could then see the readout.They have lots of options but I primarily leave it in the watt and cost output after entering the pence per kWh that my electricity company charges me. As someone else reviewed I've primarily found that the TV needed to be on eco mode, which reduces the wattage from 48 to 28. Alexa dot don't take much power at all, so less bothered about that.It's also it's worth mentioning that when you enter the cost it must be in pounds and pence, I originally put in 18.50 taking that value from my bill (18.5 pence per kWh) but that skyrocketed the cost, the manual doesn't make it obvious so I should have just entered 0.18 or 0.19
