Review: Great little item and great value - Measures the power consumption accurately for whatever is plugged in. Unlike what some reviewers have said, when unplugging it, the cumulative readings (cost and kWh) ARE retained. I like the fact that you can turn off the display if you do not want it to stay on for the 10 minutes, 1 hour, 2 hour settings that you select. It seems very accurate. Measuring as small a power draw as 0.5W is a good feature. Many other plugs do not measure so low. The user interface and 'button press' logic are sensible and not complicated at all. Although I reset the overload setting to 2900W as it says you should do this, it is not needed. The plug works and displays at least 4000W (I have my kettle and toaster in the same plug that used in this product). Have now bought a second one. And now a third for my freezer. Addendum: The display is unreadable (black) unless the backlight is turned on. This was not an issue for me as I can turn it on when I need to read it. And if you need to see it without pressing a button then there is a 24 hour on backlight option. But the instructions and website picture are misleading on this function. Addendum 2: There is one (maybe more than one) item available in a double pack which look identical and are cheaper. BUT they are not the same. I ordered a pair but returned them. Differences spotted are: You cannot adjust the maximum power amount from 3680kW. Display stays on for 15 seconds and you cannot adjust this time, nor turn the display off before the 15 seconds expires. Resetting requires pushing the reset button, but no reset tool is provided. The reset also resets the cost per unit, wheresas the item being reviewed only reses the cost and power to date and the high/low power settings. The buttons are spongey and pressing them does not always work. But if price is key then this cheaper alternative is not too much of a downgrade.
Review: Useful bit of kit for monitoring appliance usage - Useful bit of kit, the back light is a must for these devices as often plugged in away from you, this stays on for a full ten minutes which is ideal to pop back and see how things are going. it can be programmed with your tariff cost and work out current usage but as using a spreadsheet I just use the kwh along with minutes used. Good investment and would recommend this model.

## Questions & Answers

**Q: I understand most figures but what is "power factor" ?**
A: As degree qualified electronics engineer, I can say most of the answers here are rubbish. Although, there are several definitions if you look up on the internet, but I will write here the exact mathematical definition for it.

Power factor is a measure of the phase angle difference between the voltage and current.
Concepts of real and apparant power come into it.
Real power is a measure of the power where the voltage and current are in phase. Apparant power is a measure of the power when the voltage and current are not in phase. 

It's to do with resitive and inductive/capacitive loads. Inductive loads are devices which use magnetic fields in their operation such as electrical motors and even heating elements and electrical irons which contain heating elements implemented as coils of wire. A purely resistive load results in the voltage and current being in phase with each other. It is capacitive and inductive loads the which shift the phase of the current relative to the voltage, either forwards or backwards. 

The mathematical definition is:

P=V.I.Cos(theta)
P is the power
V is the voltage
I is the current.
Theta is the phase angle difference between the voltage and current waveforms.
The full stop symbols in this equation means "multiply".

Cos(theta) is the Power Factor. And the Cosine of any angle is a value between 0 and 1.
A value of 1 represents the voltage and current waveforms are in perfectly in phase with each other, where the phase difference is zero degrees, and therefore the cosine(0 degrees) is the value of 1.
 
A power factor not equal to 1, means there is apparant power being consumed.
As residential customer you don't need to worry about it. You don't get charged for the apparant power (not yet anyway although that might change in years to come with smart meters). You only get charged for real power.

The maths involved and true understanding is university degree level, though they will teach the basics to electricians. Don't worry about it. You can ignore it in a residential setting.

**Q: Will it display as low as say 0.2 watt accuratly ?**
A: Yes, the Modes 2 cumulative electrical quantity smallest energy value on the display is 0.001Kwh.

**Q: Is there a way to zero the data (kWh, Lo watts, hi watts) without resetting the entire unit and then having to re-enter the cost per kWh?**
A: Hold Function and Up. That resets the accumulated data but doesn't reset the cost per kwh.

**Q: I'd like to monitor the voltage in a socket for a period of time (24h and a week). Can I do it with this product? How does the memory function work?**
A: It has day functions but I’ve never needed to record the data to that extent.

### ⭐⭐⭐⭐⭐ Useful bit of kit for monitoring appliance usage
*by D***D on 21 September 2025*

Useful bit of kit, the back light is a must for these devices as often plugged in away from you, this stays on for a full ten minutes which is ideal to pop back and see how things are going. it can be programmed with your tariff cost and work out current usage but as using a spreadsheet I just use the kwh along with minutes used.

### ⭐⭐⭐⭐ Accurate and easy to use. Differs from the manual as it does accumulate data if less than 2 watts.
*by R***Z on 19 September 2022*

This was very easy to set up and use and is readable from shallow angles and from a distance. My unit (purchased Sept 2022), is slightly different from the one pictured in the ad as it has white alphanumeric against a blue screen. Accuracy was determined against a professional, calibrated power meter used by electricians and the calculations checked (power and cost). I entered my unit cost in pence to 2 decimal places, so it is calculated as pence, but it doesn’t look like it will cope with over 999.9 pence, so you will have to enter the unit cost in pounds losing some accuracy. (Something like 1.5% on my unit cost of 21.32 pence per KWh), so bear that in mind. Also, it says in my manual that it does not start to accumulate data if it is pulling less than 2 watts. This is not the case on my unit. My unit registers and accumulates time, wattage and cost immediately and calculates accordingly and my fire only pulls 0.8 watts in standby. A very good unit though and I will be buying another.
