Product Description
From the Manufacturer
The cost of electricity is soaring but you can help reduce your energy costs with the new Kill A Watt EZ. Simply plug it into a wall socket and then plug in your appliance to assess how efficient they really are. The large LCD will display the power consumption by the kilowatt-hour and the built-in memory retains accumulated readings when power is interrupted. Program in your local utility rate and display projected costs by hour, day, week, month, or year. Evaluate the quality of the electrical power provided from your utility company by monitoring voltage, line frequency (Hz), and power factor (VA). Perfect for detecting voltage drops and brownout conditions before they damage delicate equipment. The knowledge you gain from Kill A Watt EZ can save you thousands of dollars.
Product Description
Now you can cut your energy costs and find out what appliances are actually worth keeping plugged in. Simply connect these appliances to the Kill A Watt EZ, and it will assess how efficient they really are. The large LCD display will count consumption by the Kilowatt-hour, same as your local utility, letting you calculate your cumulative electrical expenses and forecast by the day, week, month, even an entire year. Also check the quality of your power by monitoring voltage, line frequency, and power factor. Now you’ll know if it is time for a new refrigerator or if that old air conditioner is still saving you money. With the amazing Kill A Watt EZ you'll know "watts" killing you.

I was amazed at some of the things I found around the house that draw power just sitting there doing nothing. This thing is easy to figure out and program in your cost per Kwh.
A couple of things I found by using this device:
-- the entertainment center costs me $11 a year to have just sit there in standby mode. This is a 32" LCD TV, surroundsound system, DVD player, Wii, and subwoofer all plugged into a Monster HTS 1000 MKIII PowerCenter with Clean Power Stage 2 (8 AC outlet, 2 coax, phone & network). If I watch a DVD or play the Wii, it costs me 40 cents a day, or about 3.33 cents an hour.
-- My gaming computer (Dual Core, 500 watt power supply and 19" LCD) cost me $99 a year to run 24 hours a day, 6 days a week. That includes the occasional laser printing and occasional 2.1 speaker usage. So I turn it off more often.
-- Cell phone charger: .86 cents a year, but when charging it costs me $1.73 a year.
-- New coffee pot costs me between 5-7 cents to brew a pot of coffee and let it sit for a couple hours.
-- Toaster at 350-degrees costs me about 11 cents an hour.
-- Dell laptop charger costs me about $1.70 a year to keep it plugged in. It's about a penny and hour to charge the laptop's battery.
-- NOAA handheld weather radio costs 86 cents a year to run 24/7
In the end, it seems like it is only really worth the trouble to unplug the entertainment center when not in use and turn off the computer more often. Sure, everything draws power, but we factored in the hassle of it versus the cost.
We have been unplugging stuff around the house when we are not using it, and began to wonder how much we are saving. This thing has helped out in deciding what's worth going through the hassle of unplugging each time, and the results are almost instantaneous. I highly recommend using this device to settle the score in the fight against wasted energy usage or even in helping decide which devices/appliances around your house aren't worth owning due to ridiculous power draws.
I'm still testing more items around the house, so check back later for updates.

Amazon Verified Purchase
I currently own two Kill-a-Watt P4460 meters. This usage meter has a memory hold over, so I can use these at circuits that are switched on and off. When the incoming electricity is shut off, the previous hours of use are kept in memory. When the electricity is turned back on, the meter will continue from where it left off. The older P4400 model does not have this hold over circuit. The P4460 is a great addition to the P4400 for studying home electical usage.

I give it **** because it could use a few improvements.
NOT because it didn't perform as expected.
Bottom line - great device. Works exactly as advertised.
I would recommend it to anyone interested in getting a
handle on actual electricity consumption and costs.
Best feature: The ability to enter your own actual cost per KwH
as taken from your utility bill.
Worst Feature: No battery backup for reading the collected data once
unplugged from the wall outlet. You have to plug the unit
back into the wall outlet to read the collected data.
Suggestions to the manufacturer:
1. Add a battery so the display can be read when not plugged in.
2. Include a short 12-14 inch extension cord so that you don"t have
crane your neck when reading the device while plugged into the wall
outlet. Some outlets are only 12-24 inches off the floor.
3. Make it 110/220 capable for 220V appliances.
4. Add a memory feature with a USB port to download and plot the data
over time in a spreadsheet.
5. Keep the price the same :-)

Did not meet my expectation
Does not show watt consumed instantly. It is basically for calculating monthly or yearly cost calculation which takes very long time. Read more

Great When They Work
Overall, I've been really happy with our Kill-a-Watts...when they've worked. The amp rating is a joke, however. Read more

Works, but hard to use
The monitor works as advertised, but it is very hard to use. First, it has to be plugged in in order to read it. Second, it measures every second it is plugged in. Read more
