Are your electric bills costing you a fortune? Cut costs and take control of your electrical appliances with the Kill A Watt Graphic Timer.

This advanced timer has the ability to monitor 2 tasks at once. First, it serves as a catalyst to turn your household appliances on and off as it simultaneously monitors its energy consumption so you can have total control of your electricity usage even when you are not at home. With up to 96 different programmable power on/off event settings per day, and 7 different combinations for the different days of the week, makes this device the smartest, and easiest to use, timer out there.

Not only is it a thrifty device, but the Kill A Watt GT P4480 is also the perfect tool to ward off would-be thieves by turning on and off a connected lamp at random times, giving your empty home the appearance of being occupied. The Kill A Watt function helps you save money and protects your appliances. Now, you can save energy by using lights and electronics only when you need them. The built in surge protector also guards your appliance from voltage spikes. With the simple press of a button, you can read the consumption by the kilowatt-hour and calculate electricity expenses by the day, week, month, or year.

The Kill A Watt Graphic Timer is a 3-in-1 product. It is a graphic timer with a power meter built-in that serves as a surge protector. It presents the information to you in a simple, easy-to-understand format.

Easy to Use, with Many Practical Applications

Large LCD display counts consumption by the kilowatt-hour
This is one of the most sophisticated timers on the market and yet is very easy to understand. It’s a digital version of a straightforward mechanical timer with a visual interface. It is easy to program the quarter-hour on/off periods for 7-days and 24-hours as you would program traditional mechanical timers. Unlike other timers, the graphic timer is not limited to one day of programming--the unit allows unique programs for each of the 7-days of the week. Measurements and programming are stored in memory and retained during power outages. A backup battery allows armchair programming before you even plug it in.

This fully loaded surge protector doesn’t just guard your electrical devices from voltage spikes. It also provides protection against over current, over voltage, and under voltage delivering clean safe power to your expensive equipment. When the voltage presented at the wall outlet is over or under the normal voltage range, the unit will switch to Abnormal Voltage mode shutting off the power at the outlet. Similarly when the current load presented by the connected appliance exceeds the maximum current (15A), the unit will switch to over current mode and the power will be switched off to the outlet. The GT also helps prolong the lifespan of your appliances by gently applying start-up power via its zero power crossing spike-free switch.

The power meter once connected to your appliance will assess how efficient they really are. The large LCD display will count consumption by the kilowatt/hour, same as your local utility. You can track minute-by-minute changes in electric consumption as major appliances are turned on and off. It lets you track the amount of electricity that your household uses in real time. It helps you reduce your energy consumption and decrease your monthly bills while helping the environment. Also check the quality of your power by monitoring line voltage. The unit displays the total cumulative appliance power consumption in kilowatt hours (KWH). The unit will display KWH from 0.01 KWH to 9999 KWH.

Examples of the Different Uses of the Kill A Watt Graphic Timer

Test your energy usage, set up a 7-day timer, and more

You can plug your entertainment center’s power strip into the GT and program it to turn off when you are not home to avoid any standby power from flat-panel TVs and cable boxes that suck up huge amounts of electricity even when not in use. If you need to use a connected product, the conveniently located on/off control allows a temporary override without changing the timer settings. You can go back to the timer mode very easily by hitting the "auto" button. This neat feature allows you to use power only when needed, and gives you total control of your appliances. According to the Lawrence Berkeley National Laboratory a surprisingly large number of electrical products--TVs to microwave ovens to air conditioners--cannot be switched off completely without being unplugged. These products draw power 24-hours a day, often without the knowledge of the consumer. We call this power consumption "standby power."

Use the Kill A Watt as a 7-day timer with up to 96 on/off cycles per day. You can conveniently program your Christmas lights to go on/off in a wide variety of programming options set differently for each day of the week. e.g. stay on longer in the weekends or go on earlier on Wednesdays.

Plug your lamp into the unit and use it as a security guard. It wards off would-be thieves by turning a connected lamp on and off at random times, giving your empty home the appearance of being occupied.

Test for Yourself and Observe the Results

Put the GT to the test and see how you can save money on your electricity bill. Program the GT and plug your entertainment center’s power strip but keep the timer function off. Measure one week’s cumulative power consumption in KWHs and retain the information in your records. Now turn on the timer function the following week, which will eliminate any standby power that will otherwise be used by the appliances in your entertainment center. Compare the 2-week records and see how many KWHs you have saved. Multiply the KWHs saved by the rate your utility provider charges for electricity and it will give you the total money saved that week by using the Kill A Watt Graphic Timer.

    A lot of the reviews here are for the P3 International P4460 Kill-A-Watt Monitor. I purchased the P4480 on a gold box special and am writing this review under the P4480's review page.

    I received the P4480 and opened the package and the first thing that I noticed is that it has a battery door. I opened it and saw that it takes 3xAAA batteries. These allow you to program and review the unit with it being unplugged from the wall. The backlight is orange and bright. It can be set as a night light to come on during the evening hours. The unit needs to be set with the correct time and day before it will function correctly.

    This model is not exactly what I was expecting. I thought it would be a kill-a-watt monitor with all the functions of analyzing your power consumption of an appliance or device. It turns out that it is mainly an advanced on/off timer that happens to measure voltage, amperage, and watts too. You push the volts or amps or watts buttons to scroll between measuring those values respectively. You can not enter your utilities companies KWh pricing and have it calculate your daily, weekly or yearly spending. It doesn't have a high and low points review or and kind of data logging. It only provided real time feedback of current energy conditions. This is not very helpful in analyzing the overall cumulative energy use of something.

    I recently had a lightening strike and my electrical panel needed changing out according to my electrician. The lights would dim and brighten depending on what appliances would turn on and off (ie. the A/C unit). I was interested to use the P4480 to test amps and voltages of things as the fluctuations occurred until my electrician could get out and change out the panel.

    I will say as an electrical timer, this product does work but I'm not reviewing overall usage of the product. Instead trying to point out for other potential buyers that this product is inaccurately being depicted in the description! It is missing a key feature that is available with almost every other Kill-A-Watt product yet the decription says it has this feature -- WRONG! Amazon's Technical Details say, "...Calculates electricity expenses by the day, week, month, or year... ". This is a great feature on other Kill-a-watt products (which I own) but not this one! As noted by a few others, this product does NOT have this function !!!! I have several other Kill-A-Watts that I use for this, so I can use this product as a simple timer but isn't that a little overkill, considering the price! Once again, this DEFINITELY DOES NOT offer the basic features of the other Kill-A-Watt products. I will say as an electrical timer, this product does work.
    Amazon, Please change misleading description! Thanks!

    I had the original Kill a watt and enjoyed it very much. I was excited for this one because of all of its bells and whistles. Unfortunately the safety feature is a bit annoying. The product is rated for 15 amps, as are all of them. But this one has a safety feature that will shut the whole thing down if you exceed the 15 amps. Which I guess keeps me safe but there are a lot of things that suck a lot of power that, especially on start up, will suck more than 15 amps for a short period of time. This thing freaks, shuts down and just sits there beeping at you. I never got past this before I sent it back so I did not try the programming features. I would not recommend this one unless you are only interested in "vampire" power.

    I've now gone through 6 of these P4480 timers in 2 months, and every one of them has what I think is a software problem. The clock will reset itself (blinking 12:00am) when the timer automatically shuts off (killing any future schedule you have set). Does not matter if you have new batteries in the device or not. In ADDITION, 2 of the 6, part of the display quit functioning after a few days, and this last one, the clock froze randomly, and no longer kept time. If only it always was 3pm forever! So of course yet again the timer doesn't work!!! The company did warranty replace 4 of these for me, but I've given up since every one has been the same. I had bought a 2nd unit from Amazon, thinking that maybe it would work, but again, same problems, and now I've sent that back for refund. I think this model P4480 has great potential, no other timer on the market that I can find offers a 15 minute on/off schedule every 15 minutes for every day (unlimited schedule). But they just don't work. If you do buy one of these, be sure to use it right away for a few weeks so that if it fails you can return in the warranty period. And don't use for mission critical functions. I have dead fish thanks to this timer.

    The UI is a little clunky, but this device does everything it claims to. Unfortunately, on day 5 it said my device was over current (45A) and failed to turn on. The appliance I had it on slowly ramps up when powering on (as opposed to something like a motor that spikes on power up) so I believe there is a design flaw in the P4480.

    Update: Bought the P4460 EZ model and a separate timer. No problems when used on the same appliance.
