Product details

13A Plug In Energy Saving Monitor

• 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

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 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 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 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.

Rated 1 out of 5 by from Total Rubbish Just bought this today plugged it in and I can hardly read the screen. I have to be positioned 6 inches away and still can hardly read the screen. So I rang Maplins Aylesbury where the young lad was very helpful .... He took one out of the box and plugged it in. He said he and his colleagues couldn`t read the screen either as there was no back light on it ! Don`t Maplins quality control this stuff before selling it .... ??

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 1 out of 5 by from Power monitor N67FU The units display has now got to the point I can not see it, but the unit is over a year old. Not inclined to purchase another & looking for a better replacement. Very disappointed.

Rated 2 out of 5 by from Display not readable It probably reads the consumption correctly, but the display is ridiculously hard to read as it doesn't have any illumination and the characters are quite small. I am getting this device replaced.

Rated 1 out of 5 by from Of Limited Use The display is almost impossible to read, the numeric data is large enough, but the headings indicating what the figures actually refer to , e.g. total price, power factor, Kwh or AMP are just 1mm high and some in reverse, i.e. white on black, also the plastic display screen itself is not particularly clear. It is a painful struggle to work through the instructions sufficiently to operate the device, usual for electrical devices made in China but these are more obscure than average. Most importantly, the Kwh measurement, which is, I would have thought, the main function of the device, only displays to 1 decimal place. This means it cannot be used for calculating the consumption of individual usages of an appliance. E.g. boiling 1/2/3 cups of water or charging a battery can only be determined by reading the wattage and using a stop watch to time the event and even that only works if the wattage is fairly constant throughout the period of use which is not the case for many appliances, e.g. washing machines and indeed any device that heats water and has a thermostat.

I have been using it to measure the consumption of specific items, but have not found out how to zero it between readings. Any ideas? Should there be any instructions with it? There were none in the box.

Asked by: Colin737373
FUNC button for 5 seconds to clear accumulative total electricity usage and total electricity cost while displaying total cost and usage mode or total electricity cost at either price 1 or price 2 10. LCD display ----should your total electric usage in either units or cost exceed the maximum settings, the word OVER will flash

hi, when plugged into a mains socket with no appliance attached does this device tell me the voltage being delivered to the wall socket, the mains ring voltage?

Asked by: stf1967
No, I am sorry but the item will not work for this use.

The "total usage time" is displayed as three sets of two numbers which don't seem bear any relation to any units like days, hours or minutes. What are they showing? Two examples are 35 56 26 and 31 85 26. The instructions don't explain! Thanks.

Can I put in the cost per KWh and does it then instantly show how much the device plugged into it will cost per day/ week etc, as the one I have just received from another supplier needs to be connected for over an hour to show future running costs

Asked by: freddie
Yes this product will do exactly as you require
