About this product


  • Monitor energy consumption from any appliance plugged into a socket
  • Great for seeing how much power your appliances are consuming
  • Can display the cost of electricity and power used

Product overview

• Monitor energy consumption from any appliance plugged into a socket
• Great for seeing how much power your appliances are consuming
• Can display the cost of electricity and power used
• Large LCD display
• Set up in less than 2 minutes
• Up to 9 different types of data displayed
• Memory function
• Maximum current 13 A / maximum power 3120 W

By simply entering the unit cost of your electricity and plugging an appliance or extension lead into the power monitor, the LCD screen enables you to easily see the cost of the plugged in appliances. It allows you to see useful data such as: cost generated by a socket, tariff, power factor, kilowatt hours used (as found on your electricity bill), active watts consumed, apparent power, voltage from the socket, amps used and frequency of the electricity (mains power is normally 50Hz).

Once you have input the unit pricing of your electricity the total cost will be displayed on the energy saving monitor in pence.

Rated 2 out of 5 by from I found this to be a useful piece of kit for seeing exactly how much electricity my devices use - particularly a computer which I tend to leave running all the time. I tested a number of devices over a period of a few weeks, however when I tried to use it again a few weeks later the screen was blank and the unit unresponsive. This could be a fault with it however on further investigation I suspect it could be the internal LR44 which have run out of juice and there doesn't appear to be any way of changing these without completely taking the unit apart. Quite ironic that a device made solely to measure mains power usage requires batteries to function!

Rated 4 out of 5 by from For anyone who still has this monitor (and for the price it's pretty decent / accurate) and is having battery issues, you can replace the original Ni-MH rechargeable cell (3.6V / 40mAh / 14 hour full recharge at 4mA) with item BN22Y, which has the same 3.6V rating but has twice the storage capacity at 80mAh although a full recharge will also take twice as long as it's input rating is 8mA. Tool-wise you'll need a small spanner-head screwdriver and either a soldering iron or a pair of small wire snips and a glue gun. Took me about 20mins.

Rated 5 out of 5 by from Having purchased a new type of electric heater that was supposed to be much cheaper to run than other types, we wanted to check the electrical usage. We chose this model as you can imput your exact kwh cost and it also tells you your actual cost you are using. It tells you that much information should you need this, and is easy to program, even 2 seperate prices should you need to. I was only going to use it to check the useage, but it is that good I have left it on so I can monitor the cost over time, day/week/month/winter. I am that pleased I am going to buy another heater tomorrow and go to Maplin for another monitor so I will know just what bills I have to pay with no nasty surprises. GREAT PRODUCT, very highly recommended, thank you Maplin for your service and prices.

Rated 3 out of 5 by from I purchased two of these so I could monitor two different appliances at the same time. For example, I monitored my tumble drier and freezer for a week and was suprised to find the freezer used up a lot more electricity. Unlike the devices which monitor your home consumption, this can be used to home in on one particular appliance. Besides energy consumption, the device also displays mains voltage, current and power, so you can compare the actual power of a device with the manufacturer's figure. However, the device is quite fiddly to set up. It has a small display that I find difficult to read - especially in a dark corner (which is usually where my power outlets are). You'll need a torch. The device can only monitor appliances that plug in, so it can't monitor my oven or fitted washing machine. I tried to use it to monitor the power used by my computer but it kept triggering the RCB circuit breaker next to my electricity meter. I don't know why. So it's a reasonable good device if you have good eyesight and need to monitor simple appliances which plug in.

Rated 2 out of 5 by from I plugged in this monitor and was unable to set it up because I could not read the very small and dark display screen. How could this be described as having a large LCD display? I only need glasses for reading and my eyesight is not too bad, but I could not see this with glasses and a magnifier! Will return it to the store.

Rated 3 out of 5 by from Great Gadget but ... Great gadget but ... they decided to print all the instructions on one sheet of A4 and they have used every inch of it - margins / header / footer and line spacing / leading set too small. Instructions on use not written in the most informative way but written to save space. The display requires torch and I needed a magnifying glass. No Back-light. Once you've worked out how many "func" clicks you need from what display you're on to get to what you want not too bad - great information available on it hard to see what is what - days of week and price tariffs not intuitive but I think I got the hang of them - Shame these marred a great gadget at a competitive price.

Rated 4 out of 5 by from 13amp energy monitor I am currently using one of these to monitor power consumption in my greenhouse. As the heating is thermostatically controlled and therefore dependant on weather conditions there is no other way of keeping a check on heating costs. Well worth the small cost of the product. I will be buying another.

Rated 4 out of 5 by from Just to add to my last review posted. It has a built in rechargeable NiMH battery to store the settings when unplugged. I used it to monitor my PC power usage and it worked fine.

Could you tell me what the power factor is please?

Asked by: Brian
The ratio of the actual electrical power dissipated by an AC circuit to the product of the r.m.s. values of current and voltage. The difference between the two is caused by reactance in the circuit and represents power that does no useful work.

Has this product now been redesigned so the screen is readable? Most of the poor reviews point out the poor screen display. I have two of the previous version which were good but require a couple more but I am not going to buy them looking at these review

Asked by: Robert
We have acted on the poor reviews, so the screens are more readable, but in the spirit of complete honesty, they can still be a bit hard to read in the dark.
