Electricity Usage Monitor Power Meter Plug Backlight Energy Monitor Plug Watt Meters 8 Modes, UK Socket Power Monitors Large LCD Display Consumption KWH Amp Volt Meter Outlet

Use it on a narrow boat to monitor power usage over winter, worked fine, very easy to read, gives lots of information.

Excellent device for checking electricity usage. Easy to use.

Seems to work OK, monitoring, calculating and accumulating several factors eg voltage, wattage, even cost. But in the absence of any user instructions it’s difficult to tell what some of them are and how to set them. If you just want to know how much power a particular device is using at the present time it seems to work. The display is clear, the design and the build quality good.

The plugs are working well and helping me to detect what is using a lot of electricity 😁

Cheap and simple, I just want to know the power draw of my PC and other things. Good enough

Ordered this to install on my hot tub so I could figure out the cost over a monthly period in differing weather conditions and temperatures. Enter pence/kW and it provides insight into immediate energy usage or cost per hour. Very useful.

Mine is difficult you insert a 13 amp plug the last few milimeters into the front socket of this device. At first It was so stiff I thought I would damage it. It has improved a bit with use but it shouldn't be like that. Otherwise it seems to operate as described.

so far so good.... practical, friendly and very helpful to identify the "vilans" of my energy bills

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.

mide muy exacto el consumo de electricidad

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

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.

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