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.Read more ›
In my particular case the receptacle on the Kill A Watt began to melt and turn brown when attached to a device that draws about 1,311 watts (117 Volts at 11.5 Amps ) which is below the maximum ratings of the Kill O Watt.
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 :-)
My office has been experiencing frequent partial power outages. Although we have a couple of uninterruptible power supplies (UPS) that are supposed to power the servers, telephone system, and a couple of administrative work stations in the case of power outages, we are finding that the battery back up supplies are simply shutting down without providing any power whatsoever to the hardware. We soon realized what was happening was that we had each UPS unit completely overloaded with too much equipment, so when the UPS battery was supposed to kick in, the UPS units would simply shut off completely, and we would lose all power.
Accordingly, I ordered the P4460 to take power readings of each piece of hardware so I could evenly distribute the power requirements over three different UPS units, thereby not resulting in overloading any one UPS.
Although each piece of equipment had a power consumption rating on its label, what I discovered with the P4460 completely shocked me. When each piece of equipment is powered up, there is a VERY sharp spike in power consumption, and the hardware's use of electricity reduces when the unit is up and running. For example, the phone system's video monitor power use was rated at 6 Volt Amps (VA), but when it powered up, it spiked to 85 VA. Likewise with Amps. Idle power was rated at 3 Amps, but spiked all the way to 68 Amps on startup. I found this to be the case with every piece of equipment. One server's idle power rating was 0.97 Amps and 90 VA, but on startup it jacked up to 1.92 Amps and 247 VA.Read more ›

So awesome to finally have the visibility into what various devices in my house cost to operate. I recommend this for every household!Published 4 days ago by Tony
Works great...would have been nice with a back light _ but still a very nice gadget to
Check out consumption.
Has no backlight and no battery so the only way you can read it is to leave it plugged into the wall and get down on your hands and knees and read it with a flashlight. Read morePublished 17 days ago by B. J. Rosen
Works as described. I should have spend a little more and got the one that doesn't lose all data when power goes out.Published 18 days ago by T. McClanahan
Worked just great! EVERYONE should own one! Surprising just how much electricity small items around the house can use. The entertainment center was the big shocker! Read morePublished 23 days ago by Kevin
This meter does exactly what it's supposed to do but it has a HUGE flaw that I haven't seen anyone mention. It's obviously designed to be plugged into your home AC outlet. Read morePublished 29 days ago by Jason A
