Packing Content UK power meter plug x 1 User manual x 1 Reset tool x 1 Review: Easy to use and set up - Good quality, easy to set up and use, the screen is easy to see right amount of brightness, and functions are easy and provide you with what you require,and was good value for money Review: Works fine though voltage reads 2.2V low in mine. Backlit display good. - I’ve had 2 similar meters over a number of years but the display of the second one, never good, is now difficult to read so bought this. The display is nice and clear with the additional advantage of being back-lit, which my other ones were not. Disappointingly, it has NO BATTERY BACKUP. It never occurred to me to check, just assuming it would have, like my older ones. That means that if you want to record the power use of an item of equipment over time you must ensure that the power is never switched off. Without any mains power everything returns to 0. (SEE EDIT) However, would only have been a problem for me 2 or 3 times over the last 15 years or so. Accuracy is ok but the voltage is 2.1 to 2.2 Volts low, which will have a small, though for most purposes unimportant effect on the other parameters. My old power monitor and a professional quality multimeter read 2.2V higher and another less expensive multimeter reads 2.1V higher than this new power monitor. The instructions are poor for anyone who might be unfamiliar with monitors like this. At £12.88 the price is ok and comparable to other similar products. EDIT: Although initially it did revert to zero when disconnected, it later kept its memory. Not sure if there might be a built-in rechargeable battery that was originally flat or a non-volatile memory that was somehow defective but fixed itself, but whatever the explanation, it is no longer a problem even if disconnected for days. ## Features - [Various Monitoring Parameters] The energy monitor can monitor the power (W), energy (kWh), volts, amps, hertz, power factor, cost,minimum and maximum power (W), cumulative days and time of your appliances. By switching 8 display modes, you can easily know the various parameters while the appliance is working. These power monitors can also calculate and display how much power your appliance uses and how much electricity bill it cost in cumulative time for energy saving - [Overload Protection] The default overload of the energy monitor plug is 2900W. When the power of the appliance exceeds the overload power, the LCD will display "OVERLOAD" and emit a "beep" sound to warn the user. All the buttons of wattage meter will quit working and can only work again when the overload alarm has been cleared by raising the setting value or removing the appliances - [Data Memory Function] The energy monitor will record your power consumption data when you remove electric meter from socket, or remove appliances from the power meter. All setting data and cumulative data(electricity quantity, cost, unit price) will be saved. You can directly see the last data when you use the electricity usage monitor next time(NOT including current, voltage, power, power factors). This function can also automatically save the data when there is a sudden power failure - [KWH Alarm Settings] You can set a power consumption limit, and when the accumulated power consumption reaches the set value, the energy monitoring plug uk will emit a "beep" sound, and the "KWH" alarm will flash continuously to alert the user. If you want to silence the alarm, you can set a higher power consumption limit or reset the power consumption limit (Note: resetting will clear all settings) - [Adjustable Backlight Time] Our watt meter has 5 options of backlight time. The default backlight time duration is 10 minutes(bL-0). If you want to change the backlight time, you can press and hold "UP" and "DOWN" button at the same time to enter backlight time setting, then press "UP" and "DOWN" to select the backlight time (bL-0 =10 minutes, bL-1=1 hour, bL-2=4 hours, bL-3=8 hours, bL-4=normally on), finally press the "SET" to save the backlight time settings - [Backlight Display] With white backlight and black digits, the LCD display of our power monitor plug uk can display the data clearer and help you to read the data easier no matter day or night. The backlight will only lights up when the power meter plug is connected to AC power. You can set the time for the screen to turn off automatically, or press the "DOWN" button to manually turn on and off the backlight - [Premium Material] The whole body of our power consumption plug is made of high-quality PC material, which makes our energy meter monitor more long lasting. The standard DE socket and plug is suitable for all DE standard appliances ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DNT3ZZ54 | | Best Sellers Rank | 3,444 in DIY & Tools ( See Top 100 in DIY & Tools ) 1 in Power Monitors | | Brand | MECHEER | | Colour | White | | Country Of Origin | China | | Customer Reviews | 4.4 out of 5 stars 2,067 Reviews | | Included Components | Power meter*1 User Manual*1 Reset tool x 1 | | Item Dimensions | 14 x 7 x 3 centimetres | | Item Weight | 200 Grams | | Item dimensions L x W x H | 14 x 7 x 3 centimetres | | Item weight | 200 Grams | | Manufacturer | MECHEER | | Manufacturer Part Number | JK-PM07 | | Model Number | JK-PM07 | | Number of items | 1 | | Style | White Backlight | | Style Name | White Backlight | ## Product Details - **Brand:** MECHEER - **Colour:** White - **Item dimensions L x W x H:** 14 x 7 x 3 centimetres - **Item weight:** 200 Grams - **Style:** White Backlight ## Images ![Power Meter Electricity Usage Monitor 8 Modes, Energy Monitor Plug with LCD Backlight Overload Sound Alarm.Energy Meter Power Consumption Monitors Socket KWH Amp Volt Watt Monitoring Meter Plug - Image 1](https://m.media-amazon.com/images/I/61mqPooOqhL.jpg) ![Power Meter Electricity Usage Monitor 8 Modes, Energy Monitor Plug with LCD Backlight Overload Sound Alarm.Energy Meter Power Consumption Monitors Socket KWH Amp Volt Watt Monitoring Meter Plug - Image 2](https://m.media-amazon.com/images/I/71D4nifSgZL.jpg) ![Power Meter Electricity Usage Monitor 8 Modes, Energy Monitor Plug with LCD Backlight Overload Sound Alarm.Energy Meter Power Consumption Monitors Socket KWH Amp Volt Watt Monitoring Meter Plug - Image 3](https://m.media-amazon.com/images/I/71FD-ZT4-PL.jpg) ![Power Meter Electricity Usage Monitor 8 Modes, Energy Monitor Plug with LCD Backlight Overload Sound Alarm.Energy Meter Power Consumption Monitors Socket KWH Amp Volt Watt Monitoring Meter Plug - Image 4](https://m.media-amazon.com/images/I/71iqOfif30L.jpg) ![Power Meter Electricity Usage Monitor 8 Modes, Energy Monitor Plug with LCD Backlight Overload Sound Alarm.Energy Meter Power Consumption Monitors Socket KWH Amp Volt Watt Monitoring Meter Plug - Image 5](https://m.media-amazon.com/images/I/713x5uWE6ZL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to use and set up *by P***J on 24 November 2025* Good quality, easy to set up and use, the screen is easy to see right amount of brightness, and functions are easy and provide you with what you require,and was good value for money ### ⭐⭐⭐⭐ Works fine though voltage reads 2.2V low in mine.
