The irony is that it uses even more electricity to tell you how much electricity you're using on everything else.
Rather than spending money on this, just turn things off PROPERLY when they're not being actually used, and you'll save money anyway.

good tool bought my one from maplins last year

Hot from me. I think mine was a tenner, and I think the outlay is well worth it considering the savings it can help you make when you can actually see what the effects of enabling powersaving features on your TVs and computers and stuff are. Plus, if you're at all geeky like me, you'll find the numbers of various devices kinda interesting in their way.

Btw, my Samsung 40" TV goes from around 220w to 160w by enablign the lowest level of powersaving. And my laptop's 17" screen consumes 7w at full brightness. I like knowing these things, anyway.

Why not save some money and use the existing mains meter,,,The power usage of an appliance is usually in the instruction booklet you got with the appliance,,,

Using a similar gadget I found out that my Virgin tele box consumes 13 watt on STANDBY. And they (Virgin, that is) have the nerve to tell you to keep the box on standby FOREVER as otherwise you don't get updates. Of course I now switch all the stuff off when not in use; any updates happen when you turn the box back on. Good investment.

A complete and utter waste of money

This is probably a Micky Mouse calibrated device made from Micky Mouse Chinese components in a Micky Mouse Chinese factory which is as accurate as sticking your JT into an inflated balloon and trying to guess how much air you've displaced.

Still, if a green placebo eases your enviromental conscience then go for it.:-D

Have some heat :)

So do these give proper readings and how much power do they suck?

Range of the measuring voltage: 90V - 250V (tolerance: (1%+1))

Range of the measuring current:0A - 13A (tolerance: (1.5%+25))

Range of the measuring frequency: 50 - 60Hz (tolerance 1)


Seems pretty accurate to me. Have you been practising to achieve the same accuracy in your elected pastime?

Hmmm, might grab one of these tomorrow.

It's probably nice to play with these for a few days so you can get to know what your gear is consuming, but to be honest, doesn't save you any money unless you switch off things you don't use and not leave them on standby. I bought a surge protected power strip to plug in my tv, sky box, wii, dvd player etc.. fixed it neatly on to the wall just behind my cabinet, so to save power when no using them, all I do is flick the switch on the power strip to cut the power and not have them on standby. Probably a more worthy investment getting a power strip with a switch and locate it for easy access if you intend to save power.

I bought one from Wilkinsons in Farnborough for £2.25 last week. I found the display read out very poor and difficult to read so returned it for a refund.

I cant understand why people diss this product.

We bought one a couple of years ago and 'audited' all out electical appliances and so far have saved £100's in electricity simply by switching off the energy eaters or buying newer more efficient products.

The main surprise was out dvd-vhs combi, 72 watts in standby! = about £60 quid a year not using it :O

People have known for decades that leaving things in standby consumes power and wastes money.
You dont need a gimmick like this to remind you.
