UK Plug Power Meter Energy Monitor Plug Max 13A Electricity Power Consumption Monitor with 7 Monitoring Modes and Large LCD Display

Screen is clear to read in normal light conditions.Easy to set up and has the functionality I was looking for, including low and high Watts kept.Doesn't have a back-light for the screen so if used in dark places, use the torch on your mobile smartphone or a normal torch to shine on the display.I've used it to track how many Watts were used boiling a kettle. Showed the Watts been drawn, scroll through the options revealed the amps voltage in real time then once the kettle had finished can scroll to see the highest and lowest Watts drawn.I then reset the device and tested the next appliance (don't have to reset if you want to let it continue adding up Watts consumption and days taken etc)With the fridge freezer plugged in and left for 24 hours give its usage plus high and low values.Plugged my EV 'granny charger' into it for my electric car to monitor the kwatts been drawn from mains 3 pin socket and at what rate.Other things I've tested are microwave, washing machine, toaster, slow cooker.It was useful to see that some appliances draw a but more power that is said on the label and others are within the label specifications. Useful to know if you have more than one item plugged into say an extension cord eg computer, monitor, printer, cooling fan or heater etc

I bought this prior to speccing a UPS (uninterruptible power supply) for my office at home. Although I had notional current usage figures for each of the devices I want to run, I'm aware that some of the devices I'm powering have variable current requirements, in particular the desktop pc.This simple, cheap device validated my notional figures and, because it also captures minimum and peak current, allowed me to factor these in to specify the right capacity UPS (too small and it may not last long enough to power down the pc safely, to large and it won't work efficiently with the smaller loads from the BT Home Hub, IP phone and portable phone).Money well spent for this alone, although I'm now going to use it to check some of the "on standby" current draw on other devices to see if it's as negligible as the manufacturers state!

This meter does exactly what I needed.The screen has a narrow angle of readability, but I just use a simple extension lead whenever I want to measure somewhere that it will be difficult to read. Problem solved :-)

Great for monitoring devices in house and workshop. Easy to do the math on cost of running something - just know your cost per KwH.

Just received this and for the price it is an excellent device which will help me a lot. However, could you have spent more than 30mins writing understandable instructions? They read like a machine translation from the original Cantonese, complete with inexplicable spelling mistakes and nonsensical phrases. It would take just a day to write something much more useful, which would be a much better companion to the device and allow users to actually explore the full functionality. Bung me £150 and I'll do it for you.

Recently after moving to my new house I was fitting multiple LED lights and wanted to check few wattage whether it par with what manufacturers are saying. Bought this product to measure the wattage and it seems working great for each of the electronic or LED lights that I have tested with it so far.

Very disappointed with this product. The kwh reading does not work at all so it makes it impossible to track the usage of an applicance over a period of time. You can key in the electricity cost per kw/h but this is irrelevant because the kwh reading doesn't work so neither does the 'toal cost' display.With regard to display quality, the meter could do with backlighting to make reading it easier.All in all I wasted my money.

It was well packed and delivered on time
