Empowers You to Save Hundreds on Electric Bills

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.

Kill-A-Watt has become the accepted standard in this type of power monitor meter. It does what it says, and does it well. This P3 has the advantage of having individual buttons for each of the functions. One press gets you to what function you want to look at without having to step through a menu. I just wish it had a backlight to make it easier to read in a shadowed location. Good unit though, and mine was shipped to me quickly.

5.0 out of 5 stars Knowledge is Power: Manage Your Electric Bill the SMART and EASY Way
Reviewed in the United States on May 11, 2015
Item Package Quantity: 1Color: No ColorVerified Purchase
Ever wonder how many watts an appliance is using? I have. That's why I bought this; I was wondering if my "tea machine" Tiger PDN-A50U Electric Water Dispenser, 5.0-Liter was an energy hog or a conservation appliance. Thanks to this, I now know it's an energy SAVER.

This could not be easier to use. Simply plug the meter into any wall socket. Leave it there as long as you like and use this meter like an electrical outlet. When you want to measure an appliance's electricity use, you simply press the "Watt" button & the LCD display will show you the real-time wattage usage. For example, with my "tea machine," when it boils water, it uses about 900 watts. Once it stops boiling, it uses just .3 watts, on average, to keep warm. When dispensing, it uses 62 watts (to power an electric pump), then immediately reverts back to its .3 watt "keep warm" usage.

This can also be used as a voltmeter (measuring the electricity flow INTO the outlet). For American household power, this is roughly around 120 volts (except in "brown out" conditions). Useful to check during brownout conditions, simply because using some appliances during low voltage conditions can potentially damage them (this, fortunately, rarely happens in the US, but some Californians have occasionally experienced this).

There's also a purple KwH button. This will let you measure the KwH usage of an appliance over a period of time. If you have an appliance (say, like a stereo subwoofer) that you suspect might be a Vampire Power Energy Hog (one that uses a lot of power, even when turned off), you can easily confirm this suspicion by plugging it into this meter, pressing the KwH button, & then check in 24 hours and see how many KwH your appliance has consumed. If your subwoofer's an energy hog, just unplug it when you're not using it & you'll lower your electrical bills.

I LOVE this device, because it's helped me logically evaluate actual energy usage, instead of just going by my "gut" feeling. Knowledge is Power!

This is easy to use & well worth every penny of its cost. In just a month, it more than pays for itself, if you've not been paying sufficient attention to your energy use. Now, instead of guessing how much power you're actually using to operate an appliance, now you can know. Great for everything from rice cookers, tea machines, toaster ovens, computers, printers, stereo equipment, battery chargers & more. A+!

I allow my tenants to have an AC unit only if they use a power counter like this. i then bill them for the power used at the end of the month. (I pay the utilities in the building) This works well for everybody.

3.0 out of 5 stars Hard to read in low light.

The ease of use is without question. However, the display is impossible to read in low light. Using a flashlight drowns out the display and is very frustrating. Daytime use with natural lighting, it’s perfect and easy to use. Would recommend a backlight feature.

If you live in the UK, do NOT buy this product. It is not designed for the UK and you will have to return it. The company, so far, has refused to pay the return postage, even though this is entirely their mistake. I have no idea why it is not clearly labelled.

Fantástica compra, cumplió todas mis expectativas y al tener un soporte de hasta 1.8kw me permite medir dispositivos de alto consumo.

Quien iba a decir que mi PC (solo el gabinete) consume 4 veces mas que mi refri de 7 pies. Gracias a esta maravilla, ahora lo sé.

Recomendadísimo, entrega en excelentes condiciones y vino empaquetado con su bolsa antigolpes.

1. Operating voltage is incompatible with Japan's 100VAC.
2. Seller support is poor and maker (P3) doesn't respond to emailed questions.

A waste of money.
