(Sold Out) P3 Kill a Watt Electricity Usage Meter for $17.99 Shipped

"The Kill A Watt P4400 - P3 International Electricity Usage Monitor - Bulk Package (Free Ground Shipping) is not currently available. Please contact us for availability of this item. "

I didn't really want to spend the money on this anyway :( Although, I think it would ultimately save me money as I have a few items that I know I should turn off more often :) to save a bit!

These are pretty handy. Its interesting to like check your unloaded laptop brick and see how much power it wastes plugged in.

It also does cumulative analysis. Like for a fridge. The real power use there can only be calculated over long cycles to understand how often it runs, etc. This device does that too.

But the biggest thing was that it convinced me to turn off the gaming systems when not in use. They were pulling like 450w quiescient. More when hammering. So I now turn them off if Im not going to be on in more than 2 hours.

:boogy:

I have the EZ version of it, pretty good
I found out my Core 2 Quad system uses about 130 watt in idle, 160 when busy
My xbox uses 150 in indle, 180 when playing games

It is a good tool for you to know exactly how many power the device uses.
 
yup

What makes you think that it's accurate?

Better ones cost more than $100,

If you want an electrical engineer's take on that...

I'd say these are VERY accurate, at least to the degree a consumer would need. Very accurate Digital DVM's are now like $10. The only measurements this thing has to take is current and voltage; both very easily sampled and generally the measurement are highly linear within household ranges (voltages maybe 110 to 120, and current maybe 10ma to 10A, and consistent temperatures).

Who cares if its even off 5%- it still tells you (Im wasting power) or (I can leave this plugged in its negligable.)...
