 P3 International P4460 Electricity Usage Monitor July 23, 2007

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 :-)
 Product not working, tech support unresponsive December 28, 2007

The Kill-A-Watt I was shipped was dead on arrival - the LCD display did not work. I tried calling customer support several times but would always get voicemail - I left a message, but never received a callback. Then I tried emailing them, hoping they would be more responsive there - but again, no response to either of my emails. So while this may be a very nice product, be aware that there are some lemons out there and you may not get any help from the manufacturer if you end up with one. Best to buy from a vendor with a good return policy, just in case.
 P4460 is great for electical circuits that loose power. October 18, 2007

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 really like these power meters, but some of them are not very accurate. I have tried 3 P4460s and several of the cheaper models and found that one of the P4460s read 86 watts when it should have been 80. That's off by 7.5% and is way out of spec according to the manual (which says it is suppose to have .5% to 2% accuracy). I am returning that unit (the replacement I bought reads 83 watts which is better). Some of the other units were off too, but not by as much. Otherwise this is a nice unit but could include an optional short power cable which makes it much easier to handle and use. I like the fact that this unit does not lose readings when power is lost.
Works great; fast results. May 4, 2008

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.
