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. The large LCD display counts consumption by the kilowatt-hour, the 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 will know if it is time for a new refrigerator or if that old air conditioner is still saving you money. Kill A Watt can help you reduce your power bill and will help find power-wasting appliances so you are able to decide whether it is worth keeping them plugged in. For standard 115 VAC appliances only, 15 amps maximum, 125 VAC maximum.

Find Out How Much Electricity You're Using

The U.S Department of Energy reports that 20% of our electric bills come from items that are left plugged in when they are not in use, or items that are in standby mode. With the Kill A Watt P4400 we can monitor the energy eaters in our homes and cut down our electric bills at the same time. Plug whatever item you want into the device and it will tell you the efficiency of that item by displaying the kilowatt per hour. This device will help you determine which items are costing you the most to run. The Kill A Watt also calculates voltage, line frequency, current, and power factor. You can calculate your electric bill before you even receive it from the electric company.

Test The Quality of Your Home's Power

But measuring appliance consumption is just the tip of the iceberg. Because it can monitor voltage (Volt) and line frequency it can also test if an outlet is working, or evaluate the quality of the electrical power provided by your utility company. It can detect voltage drops around the house, help to predict brownout conditions or to make sure a new home's outlets are in working condition before escrow closes.

This is a review of the P3 P4400 Kill A Watt Electricity Usage Meter. (Measures 5.13”h x 2.38”w and 1.63” deep.) Summary – I wanted something that was super easy to use and gave me a lot of feedback as to my electrical uses of certain setups. For me, I wanted to check wattage – amps I was using on a single outlet powering numerous devices to ensure the line is not being over loaded. This thing is great and would recommend to anyone wanting to have a little more knowledge of their electrical device usage. As with all my reviews, I will update this should this develop any issues with ongoing use. Pros LCD is a nice size and easy to read. Has a wide power range. Operates on 115-125vac and handles up to 15A – 1875 VA. Can select to view volts, amps, watts/va, hz/pf and KWH. My needs for this was to identify watts of certain items (to calculate backup generator size), amps, volts as well as to find out KWH to estimate my electrical costs. You would just need to find your recent electrical bill or look up online to identify your particular cost. Ironically, it is also very useful in seeing which items draw the most while inactive as well as which devices take much more of a startup amperage such as laser printers. Design is plug and play and extremely easy to operate. Comes with 6 month warranty. Wish List Backlit display. Increased amperage to approx. 20 to cover newer home wiring and loads. USB output for software based analysis and easy viewing.

    Accurate, Simple, and Addictively Useful

    The P3 Kill A Watt Electricity Usage Monitor is one of those inexpensive gadgets that quietly changes how you think about energy use. I first bought it to see how much power my old refrigerator was pulling—and ended up testing every appliance in the house. Setup is instant: plug it into the wall, connect any device, and the bright LCD display immediately shows volts, amps, and watts in real time. Leave it running for hours or days, and it totals up the kilowatt-hours (kWh), letting you see exactly what that appliance costs you per day or month.

    What makes it so helpful is how accurate and intuitive it is. You don’t need to be an engineer—just read the wattage and multiply by your utility rate. I found a few “phantom” power hogs drawing 10–20 watts even when off (like a cable box and an older UPS). It’s also great for testing PC builds, aquarium setups, or any electronics to ensure your power supply is sufficient.

    The build quality is solid, and the display remains easy to read even after years of use. The only caution: it’s designed for 115V North American outlets only—not for international use.

    Bottom line: A must-have tool for anyone curious about energy use or looking to cut electric bills. Simple, accurate, and surprisingly enlightening—it pays for itself quickly.

    This product works as expected. I purchased this unit to make an analisis about parasit power consumption in my electronic appliances in home.

    I discover the following:

    - the lcd requires 180 ~ 230 watts. After going to standby or shutdown, the tv use 60 watts for 3 minutes. This is to cool down the lcd lamp for protection (fans and additional circuit works for this time). Can be a mistake if I remove the AC cable power or enterely shutdown the tv without allow this process to finish. Good discover. After this 3 minutes, the standby mode on the monitor only requires 05. to 1w.

    - my motorola cable system requires the same ammount of power (27 ~ 30 watts) no matter if this unit is ON or off!!!!... all the time is fully powered (because have an internal hard drive). But I believe (wrong!) this unit must save about 50% if is off.. but no!!!!

    - the blackberry / sony ericson chargers do not drain any power (0W) from AC if the phone itself is not connected. I DON't need to disconect this chargers from the outlets.

    - My APC Smart UPS 1500 drain 30 WATTS! even when is completely turned off!!!Is better to disconnect this unit from the ac cable!!! amazing!...

    - My pc (dimension 9150) is a power hungry pc. Because have pentium D (first edition) who requires a lot of power. This pc requires 230 watts but when I play Command Conquer (3D real time strategy) and because I have a HD2900 ATI High Definition card who requires 650 watts PSU. Interesting: when I play the game the power rise from 230 to 300~320 watts!!!!

    This unit is very usefull to understand how the electronic systems works and if are energy efficient and how you must manage this units to save power and money.

    Highly recommended, is cheap and you can check your ac freq and exact voltage (i have 128 volts from 127 expected in the ac line)......

    Size: Original versionVerified Purchase
    The Kill A Watt Energy Monitor (I have the P4400) can be mighty useful for determining energy usage of plug-connected devices, especially ones with varying usage, such as refrigerators, plug-connected air conditioners, humidifiers and dehumidifiers, and perhaps computers.

    I got mine in 2018, so it may not be quite the same as current models.

    A few things could be improved:

    • It would be mighty nice for the display to have a backlight. But, unlike some others, I have no problem reading it when shining a flashlight on it in a dark location.

    • For some devices (e.g., a refrigerator), it can be mighty inconvenient to read without using at least one extension cord, which is a bit Mickey Mouse. A Kill A Watt Connect (https://www.amazon.com/dp/B0CVS4WXM9) might address this, but some have suggested the 32″ connecting cable is on the short side. I don’t have that model, so I can’t comment from experience.

    • When plugged into the top outlet in a duplex receptacle, it blocks the lower receptacle. Again, a short extension cord could fix this.

    • As several others have noted, the outlet receptacle is mighty tight. Not so tight as to be unusable, but much tighter than a normal receptacle—and it doesn’t have the same feel as a hospital-grade receptacle, which is also pretty snug.

    • There is no battery backup, so acquired data are lost in a power failure. Power failures where I live are infrequent, so this isn’t a big deal for me. There are other models that do have battery backup.

    This model doesn’t calculate energy cost (some others do), but this isn’t a big deal for me; I think it’s probably easier to just put the energy consumption data in a spreadsheet and figure the cost there.

    There are some other brands that cost less and even have more features; I haven’t tried them so I can’t really comment. I haven’t felt the need for most of these features strongly enough to try another model.

    Were it possible, I’d probably give the Kill A Watt a 4.5.

    A Poor Man’s Clamp Meter?
    For devices like a hair dryer or toaster that have relatively constant consumption when in use, I’m not sure it’s necessary to accumulate months of data unless one is a real fanatic—so a quick measurement will often suffice.
    Though intended for monitoring energy use, the Kill A Watt is also an economical substitute for a clamp meter and line splitter. I have a hard time believing that it’s in the same league, but the specifications suggest otherwise—and the indicated values are very close to what I get with a Fluke 87 and i400 current clamp. For someone who’s not an electrician, the Kill A Watt may well be good enough, and it’s easier to use and less expensive. One big convenience: it’s easy to quickly switch between current and voltage under load at the press of a button, which is much harder to do with fancy meter.

    The Kill A Watt also provides watts, VA, and power factor at the press of a button. Results can sometimes be surprising: I have one low-flicker LED bulb with a power factor of 0.7, while this isn’t great, I remind myself that the VA is still a lot less than that of an incandescent bulb with a unity power factor. And it’s interesting just to know this stuff.
    For this purpose, the Kill A Watt seems better suited than some of the newer models with extra features that don’t really apply.

    Works as expected. Just plugged the coffee machine into mine to see what the draw is when it's not running. Make sure you read the manual and set the $/kwh so it calculates it correctly for the cost in your area. It does take some time to come to equilibrium on that so leave it for a bit.

You can calculate your electric bill before you even receive it from the electric company. Test The Quality of Your Home's Power But measuring appliance consumption is just the tip of the iceberg. Because it can monitor voltage (Volt) and line frequency it can also test if an outlet is working, or evaluate the quality of the electrical power provided by your utility company. It can detect voltage drops around the house, help to predict brownout conditions or to make sure a new home's outlets are in working condition before escrow closes.
