Tools and Hardware Reviews of P3 International P4400 Kill A Watt Electricity Usage Monitor
Customer Review: Simple way to monitor electricity usage
Summary: 5 Stars
This monitor is very simple! There is a 3-pronged electrical outlet in the front and a 3-pronger electrical plug in the back. Plug the meter into a wall outlet, then plug in any device into the front of the meter. Simple. You need to stick to items of 120 volt, 60 Hz, and less than 15 amps - but that covers most normal stuff.
It measures volts, amps, watts, and kilowatt-hours (kWh) by the push of a button. A digital display shows the results. The kWh function has a timer so you can see how many minutes it takes to reach one kWh (to calculate monthly cost from your power bill).
You can leave it in for any length of time. I measured my computer/printer electrical usage over several days and was surprised at how much power they used WHEN TURNED OFF (e.g. "vampire" electricity usage in the popular literature).
Simple and easy for completing your own home energy audits.
Customer Review: Best Money I have spent on Amazon
Summary: 5 Stars
I am just so pleased with this Kill A Watt unit. It has been fun to use and and investigate all my power consumption. Some things are just for infomational purposes because I can't unplug them(i.e. Refridgerator) and others are devices where we can change our habits some and start savinfg some real money every month.
Pros: Easy to use, inexpensive, small profile,
Cons: Setting disapear when unplugged, zero directions
I think that the company that made this unit could be more helpful if they were to offer a spreadsheet on their website that people could download and use for figuring out their power consumption. I made one myself but it took a lot of time. Also not everyone is good at math and formulas it would be helpful if they offered a small cheat sheet for people to use to help them get started on the math of KWH and how we are all bileed for our electricity.
Customer Review: Very good product delivers as promised
Summary: 5 Stars
This product performs as advertised. It allows you to collect the total electrical usage of a 120V plug-in appliance. Very handy for appliances that cycle on and off (like a refrigerator). A handy supplement to a multimeter for measuring current and power of 120V plug-in appliances.
You can easily determine how much power a specific appliance in your home is using - then determine if there is a payback to replace the item with a newer more efficient item. You can determine how to manage your electrical usage after monitoring your plug-in appliances.
This product will not measure the power or current of hardwired appliances or appliances that operate on voltages other than 120 (ceiling fans, electric water heaters, central AC). For these things you will need to measure the voltage and current using a capable multimeter and manually log their run time to determine their electrical usage.
Customer Review: Death to the myth of watt usage--our answer is finally here!

P3 International P4400 Kill A Watt Electricity Usage Monitor
No BULL!! This device does everything it claims--and maybe more. It can't reduce your power consumption, but it can let you know EXACTLY how much power a specific device is using. Let the pundents make their bets--then plug this baby in--and prove them worng. I like how it even has an accumulated time feature, so everyone knows the reading is legit.
Gives volts, watts, watt-hours, frequency, etc.
Yes, you do have to do some 3rd grade math to add up the scores, but given the lower cost of this model, you'll probably want two of these in your house anyway.
You can track power consumption of anything from a refrigerator to a power strip. (No knocking down candles at night, just to ocnserve the maximum power possible!!)
Customer Review: Works as expected. And price is good.
Summary: 5 Stars
If you want to find out just how much electricity that new PC is using, in real time, then this monitor works great. I see mine is 135w now, but only 35 when in sleep mode.
The monitor just plugs into a grounded wall socket and then you plug in the device to be measured. (My UPS power supply even let me do this without turning off the computer.) Because the unit is fairly large, tight spaces or crowded plugs may be an issue. I just plugged it into a empty extension strip I had and then just plug the strip into the wall. This also extends the unit to make it easier to see the display. Display is not backlit, so a flashlight might be needed.
The unit does not compute costs, but does capture KWH's over time, so not hard to do the math. But, I use it more to find the real-time watts being used. (My HDTV uses 148w on and <2w standby mode.)
