 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.
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.
This product is really great! January 8, 2008

This power monitor is really great. I bought a few of them and gave the others as gifts. I think it's worth the extra money for this model to be able to enter your cost from your electric bill and have the unit read out the cost per hour, day, week, month or year! One review complained about it being hard to read when plugged into the wall. Just use it with a short extension cord if the outlet for your refrigerator is behind it. Make sure the extension cord is the proper gauge, 14 gauge for a 15 amp circuit. This thing is so easy to use, you may not even need to read the directions! When you have collected enough data to get the proper accuracy, you can unplug it from the product and plug it in somewhere else to read the data. It doesn't loose the data, just read it out right away so it doesn't count any no energy use time and average it in with your previously collected data. When you are done and reset the unit to start monitoring another product, it clears the data but leaves the cost per kilowatt hour that you entered from you utility bill.
My review of the P4460 Electricity Usage Monitor January 14, 2008

Please read this entire review. There is an eye-opening surprise to the use of the P4460.
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.
If I had only used each piece of equipment's listed power consumption on its label, I never would have known about the power spikes on startup, which, when combined, will absolutely overload a UPS, even though the combined idle power consumption falls within the UPS battery backup tolerances.
The P4460 is a terrific little unit and can even be used for extended periods of time for accurate power readings on equipment that cycles on and off, such as refrigerator compressors.
It's a bit more expensive than its smaller cousin, but worth every penny. Provides several types of readings and comes with very detailed instructions on how to use it so even a complete novice who knows nothing of electricity can benefit from its use.
I give this little unit a solid 5 stars.
A very handy device. January 7, 2008

I actually bought 2 of these, one was a gift. It works exactly as advertised so that is a plus right off the bat. I bought the EZ model which will make the Kilowatt hour/cost calculation for you; the less expensive model gives you the watt usage only and you have to do the math. For the EZ model you just put in the price per Kwh from your electric bill and it figures out the rest. I would recommend getting (2) 3-pronged extension cords, one to go from the plug on the back of the Kilowatt EZ into the wall socket and one to go from the appliance cord your testing into the front of the Kilowatt. This will eliminate having to get down onto the floor to read the thing. For instance my refrigerator plug is on the floor behind the fridge, not too convenient. If I didn't have an extension cord I would have to move the fridge all the way out and use a flashlight to read the screen. But once you overcome this rather obvious design limitation the product is a lot of fun to use. I was always concerned at how much my Christmas lights must be costing me so I tested it out. My big tree which has something like 700 lights costs $0.03/hr. Less than I expected. My outdoor lights cost about $0.10/hr. Not too bad either. My (2) tivo's use as much juice as my refrigerator which was a bit of a mind blower. Using this thing has made me more energy aware and I find myself shutting off things that aren't being used. I put power strips on certain "phantom" devices that suck power even when off like my TV and Stereo and DVD player. Get one, you'll see for yourself.
