KETOTEK Watt Meter Power Meter Plug Electricity Usage Monitor, Energy Monitor with Backlight, Kilowatt Meter Socket Outlet, Voltage Amps Power Consumption Meter, Overload Protection

Super bright display, really useful
I bought this gadget as a toy but it’s actually paying for itself. My incandescent landscape lights turned out to be the biggest Watt-hog of all, at $100 a year. Switching to LEDs should cut that to $15 per year.Here are my results for other household appliances:Clothes washer – 0.67 cents per loadElectric blanket – 3 cents per dayDesktop computer – 5 cents per dayDishwasher – 7.5 cents per loadRefrigerator – 19 cents per dayA lot of vendors sell something similar to this. I picked this model because of the bright, readable display, and I’m pleased with that. I had to reset the device right away to get it to work, and I’ve had to reset it again since then. And I have to say, the instructions in microscopic print in seven languages are totally useless. But the unit seems to be well-made and it does everything it should do. I recommend it.

Timing starts below 2W
Product information says “When the power of the connected device exceeds 2W, the meter will start timing”. This is exactly why I purchased this product. I have an automatic pump that turns on when the water level reaches 1 inch. The KETOTEK reads 0.013A,0.6W when the pump is idle, and 2A,232W when it is pumping water. I want to know the cumulative time it was pumping, not the total time it was powered on. The TOTAL TIME on unit I received starts immediately and increments continuously at 0.013A,0.6W. Is there any way to adjust this?

Good Quality & Accurate
Very impressed by this AC outlet monitor and meter!For the money, this thing is gold!Helped me figure out why my LED shop lights were flashing every so often. The voltage was varying from 122v down to 116v. And everytime the lights flashed and flickered, it read a low voltage.I haven’t utilized it to monitor how much power it uses over a period of time yet.I did use it to see how many watts the LED lights were using, and it was accurate according to what the lights were rated at.Good product. GREAT value!

It more than a kilowatt meter
It also has kilowatt usage tracking so it counts how many kilowatt hours you use while you time it.It shows the peak draw and the low draw to show you the draw range of the plugged in appliances.It has a light up screen while plugged into the wall.Those are the main ones i used to find out how much draw my appliances were using.has more stuff though.

This energy meter plug operates stand-alone and straight forward to use. It does not depend on any App or Internet connection, unlike smart plugs. It is narrower than many energy meters I’ve used, fitting next to regular UK plugs with most power strips. From going through the menus, it measures the accumulated kWh, running cost (single 24hr tariff only) and runtime in days, hours and minutes. The runtime LED lights up and accumulate the runtime whenever the appliance draws above 2 watts.It has several screens of readouts as shown in the video clip. These include watts/cost, kWh/runtime, estimated CO2, volts/Hz, amps/power factor, minimum watts and maximum watts. It reads all the way down to about 0.1W from my testing, which means it can measure standby power consumption, unlike some energy meters I’ve used that shows zero for anything drawing under 5 to 8 watts. Just 1 watt of standby power left plugged in 24/7 adds up to 8.76kWh annually. It also measures power factor well, such as power supplies, dimmers and LED lamps that have poor factor usage.There is no backlight, however, the screen has a much wider viewing angle than my other energy meters. It can also display the readings while unplugged, even when left unplugged for several days. There are a few user-settable alarm settings for overload, kWh and cost. These alarms don’t make any sound, but just cause the blue LED to blink continuously when an alarm is tripped.There are a few niggles, such as resetting the kWh will also wipe all the other readings, including the cost and alarm settings. There is no ability to reset the minimum and maximum wattage readings either without a full reset. It would also be nice if it could handle multiple tariffs, particularly for measuring appliances that run overnight.

Good product. Does what is says on the box.

This Electric Usage Monitor is a simple enough tool for finding out just how much electricity a particular appliance is using. It can be particularly useful for seeing how much an item on ‘standby’ can leach.Setting up is not difficult with just a few button presses to input the rate your energy company is charging for a unit of energy.There are 7 modes to this device, all listed above in the advert, with perhaps the most pertinent one being (in these days of astronomical energy prices) the actual cost of the power used on a device over a period of time.It fits well on a double socket and does not impair access to any switches. The display is uncluttered and very readable although if looked at from an angle it does become more difficult to read – a backlight might have helped in this respect.I assume this device is accurate. I do have a similar device from another brand that gives pretty similar readings, so I am happy with the read out this unit provides. There is a memory to this device which holds on to any settings while a socket is turned off, although how long this lasts I am not sure as up to now my device has been in constant use. It keeps the input cost per unit, time a particular appliance has been in use and such data, but not ‘on the fly’ data like current voltage.Likes:Not too large and does not overly obscure socket switchesLarge, clear displayEasy to use buttonsEasy to set upGood set of information availableDevice has a basic memory functionDislikes:None, other than there is no display backlight
