Product Description

Electricity bills are rising. Now you can cut down on costs and find out what appliances are actually worth keeping plugged in. Simply connect these appliances to the Kill A Watt, and it will assess how efficient they really are. Large LCD display will count consumption by the Kilowatt-hour, same as your local utility. You can calculate your electrical expenses 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.

I think this is a tremendous value. So many of us are uncertain how much power some of our appliances are using, even when they are "off" (such as devices with remote controls, which must maintain power to the receiver in case the remote is used to turn the device "on").

My only disappointment was that all the collected info disappears when you unplug the monitor - there's no "memory" feature, and it's sometimes difficult to see the readout if the unit is plugged in behind an appliance or in a floor outlet (just put a small extension cord between it and the outlet). But for $25, this is still a great buy, a great conversation piece, and something your friends and neighbours will all clamor to borrow (if you ever finish testing all your appliances!)

I was trying to find how many Amps some appliances were drawing , so I could decide on the size of a portable generator I needed to purchase to ensure my home was protected when a power failure came upon us .

We needed the sump pump to work & run the fan on the Natural Gas fire place to heat the house . Thanks to Kill a Watt I made an educated decision that a 1200 watt generator would keep our home safe from water damage & give us enough heat with out spending a fortune on a fancy generator . With funds limited we survived a 40 hr, outage .

I used this to measure the usage of my 40 year old freezer, and my 21 YO fridge. I was suprised to see how little electricity they each used. However I will check the freezer again when the weather is hotter.

Can be hard to read when plugged into the wall, and looses all measurements when it is unplugged.

Friends want to borrow it to check their appliances.

Pro:
- Donne les infos de consommation tel que spécifié.
- Le degré de précision correspond aux spécifications.
Cons:
- Il est très difficile de débrancher l'appareil de ce compteur, les ergots de branchement sont très serrés.
- La lecture des informations n'est pas toujours facile car il faut que l'appareil reste branché au mur pour conserver les infos enregistrées. Il faut souvent se contorsionner (par exemple derrière un frigo) pour accéder aux infos. Il serait souhaitable qu'une pile soit ajoutée afin de conserver les infos et qu'un bouton de remise à zéro soit ajouté.

This thing is great. I can tell how much power anything in the house uses, on 120V of course. The ability to estimate costs is fantastic. Friends ask me to bring it to their house for some testing.

Must have for geeks!

No complaints at first. Using it for my sons gaming computer. Worked great for about 5 days until it just flat out died. Has now been three days running through their company maze trying to get hold of Tech Support for "trouble shooting". End result will probably be another $10 -$15 to ship it back for repair. Such a hassle! Anyways, hope others have better luck. Like I said, when it was working it did as advertised. Just wish mine had lasted longer than a week.
