kuman KW47-US Electricity Usage Monitor Plug Power Watt Voltage Amps Meter with Digital LCD, Overload Protection and 7 Display Modes for Energy Saving (NO-Backlight), white

To reduce expenses and to help protect the environment, in early 2021 our household started taking a number of measures to cut our energy consumption. Those measures have proven successful: total 2021 electricity consumption in our single-family, detached home in the US SE was about 8,000 kWh (3,200 of which was for HVAC), compared to about 11,000 kWh annual average in previous years. [UPDATE on 1/1/23: our total electricity consumption in 2022 dropped even further to just 5,500 kWh (1,600 of which was for HVAC) for the year. We have HALVED our electricity consumption. Huge savings. This electricity usage monitor continues to operate beautifully. We lend it to friends and family so that they can do their own diagnostics at their homes and see where they can save.]Looking back, we can say that purchasing the Kuman Electricity Usage Monitor Plug has been one of our wisest and most useful moves, and a very inexpensive one at that.The Usage Monitor Plug helped us to gain really eye-opening – and often surprising – insights into our electricity usage, allowing us to identify specific steps we could take to reduce consumption. Most importantly, we learned that “phantom power,” or the energy consumed by things when they are plugged in but not being used, accounted for a lot of our waste. Here are just a few examples:We discovered that our microwave used 64 kWh annually … in standby mode. We estimate that our actual annual use of the microwave takes less than 60 kWh. We now unplug it when we’re not using it.Another big consumer is our modem/router, coming in at 88 kWh/year. We now unplug it when the last person calls it a night. For people with set schedules, a timer switch would also work.Among the other major users of phantom energy are our TV w/ accessories (138 kWh/year when not being used but left plugged in) and our CD player (60 kWh/year in standby).One final example: Our rather old dishwasher is a real glutton, coming in at nearly 700 kWh/year. Newer, more energy-efficient models use less that 200 kWh/year. The next time our dishwasher breaks down, we will replace it rather than repair it.Finally, here are some other products we purchased at Amazon that we can recommend to those interested in cutting home energy consumption:Klein Tools TI250 Rechargeable Thermal Imager: http://www.amazon.com/gp/product/B089QW8R9S This tool, along with the Usage Monitor Plug, gave us a very good picture of where we were wasting energy. It was thanks to this tool that we realized, for example, that our then uninsulated recessed lights were really problematic, prompting us to purchase the following.FF130E Recessed Light Cover: http://www.amazon.com/gp/product/B002XVPUAO If you have recessed lights and they’re not well insulated in the attic, energy wastage can be massive. These were easy to put in, sealed with Great Stuff: http://www.amazon.com/gp/product/B00KSANBTYAcuRite Wireless Indoor Outdoor Temperature and Humidity Sensor: http://www.amazon.com/gp/product/B00T0K8NXC We got two of these to go with our AcuRite weather station. They allow us to monitor temperature and humidity in four places at once: outside, in our living room, in our crawlspace, and in our unfinished attic. Thanks to these readings, we have established a smarter, more energy-efficient way of ventilating our crawlspace. They also helped us see that our attic needed additional ventilation in the roof, prompting us to purchase the following.4 SEASONS Solar Powered Polycarbonate Vent, Weatherproof Design, Quietly Cools Up to 500 Sq Ft, 400 CFM: http://www.amazon.com/gp/product/B01DMSCPJAAootek solar lights 120 LEDs with lights reflector, 270 degree Wide Angle, IP65 Waterproof, Security Lights for Front Door, Yard, Garage, Deck (4 pack): https://www.amazon.com/gp/product/B07NQ4L1SB , as well as Solar Lights Outdoor,WWimy 210 LED 2500LM Motion Sensor Lights with Remote Control, 3 Heads Security LED Flood Lights, IP65 Waterproof, 270° Wide Angle Illumination Wall Lights with 3 Modes (2 Packs): http://www.amazon.com/gp/product/B08T9F2MM1 Purchased in August 2021, these lights continue to work well here in the SE, saving us over 150 kWh/year.

I’ve wanted one of these for a while and I finally bought it. And it’s made a difference. I was able to find energy hogs, and it even helped me determine I had a fridge with a compressor issue. I lent this out to a friend with roommates and she used it to know exactly how much power she used which resolved a dispute and saved her money.

Great power monitor. Battery back up is great as it does not have tp be plugged in to view recorded readings.

It seems like we cannot ever have enough outlets in our house. We have power strips and outlet adapters everywhere to accommodate all of our devices. That being said, I was always concerned about overloading any particular circuit and potentially tripping a breaker or creating a fire hazard.I have a couple of devices that use a lot of power when on (hair dryer, treadmill, room A/C) . Check your breaker box for the AMP rating the circuit you are monitoring is on. At 120V (US standard):20 AMP Circuit = 2,400 watts max15 AMP Circuit = 1,800 watts maxEnter this great device! Plug everything into it and you can see the maximum wattage used over the entire period you chose to monitor.

So my coffee maker has an auto on and auto off feature, but I noticed that if I start it from the off state or already on, it takes the same time to brew, and everything felt cool to the touch which got me wondering if it preheated the water at all or if it was literally a pointless feature. It had an annoying thing that you have to turn it on for it to recognize that you changed the k-cup for it to brew, so if you did things out of order you would have to turn it on, pop it open again, close it, then brew. Anyway, I bought this meter to track power usage… sure enough, no power used with it on 24/7, or off 24/7… it only used power when it was actively brewing. Therefor I shut the auto on-off schedule thing off and now I no longer get frustrated by doing a step out of order while half asleep pre-coffee.Long story short, I’ve measured a LOT of things in my house now and got a better feeling of some of the energy hogs and some of the things that barely use anything. Some of the bigger power eaters are worth replacing with newer ones sooner than later now that I see what it actually costs me to run compared to newer much more efficient things.
