P3 Internatoinal P4400 Kill A Watt Energy Monitor

Model %234400. Durable construction. Case color is a little different than the one I bought 13 years ago, but is otherwise the same product.I don't think this model is made any more, as it is not found on the company's website. They do make similar products now, but I like the familiarity of this one.

Our local utility company has a number of these units that they lend out. I was so impressed that I bought one to have around the house. Easy to use but I had to write to the company on "how to" calculate the actual $$$ cost. They replied promptly. I also found a website that had an easy to use table. I found a couple of "energy hogs" in my house that should save me the cost of this device in 2 months. This unit does NOT have a battery backup so you might need to use a SHORT extension cord of the correct gauge wire so you can read it. Once you unplug it from the wall, the data is GONE. No big deal. I just had to do this with the refrigerator.

Bought this instrument to determine what kind of electrical load was being put on individual electrical circuits. I live in an old, old house that has some 14 ga. wiring along with 12 ga. wiring so it is essential to know how much of an electrical load overall is being put on individual circuits and how much power individual appliances are drawing. I am using it on mostly portable appliances right now. I was surprised to find on two different space heaters that are rated at 1500 watts each, one draws 1350 watts and the other draws 1630 watts. I certainly would not recommend either of these two heaters on 14 ga. wiring. I also have a wood insert stove with 4 fans. Again, I was surprised. This appliance draws only 1 watt of power. I was sure it drew more. Most people are not concerned with the electrical power portable appliances (or permenant ones) draw. That is why they will try operate a microwave and a toaster at the same time on the same circuit. This instrument can tell you quick how much load you are putting on a circuit. This instrument has 5 different settings: volts, watts, amperes, amp hours, and kilowat hours. No better educated than I am in this area, I can moniter my appliances and understand what is a better setting and placing for them and how to keep from overloading a circuit.

I've used these for years, both to learn what an appliance actually uses in electrical usage, and to teach people of all ages about electricity and power usage. The label on the appliance is often just an estimate; this is the simplest and least expensive tool for assessing its actual usage. They used to be $40 each and hard to find, to it's great to see them readily available and selling in volume!

Totally happy with kill-a-watt.Performs to expectations. Just what I was looking for. Its amazing your electronics are still using electricity even when turned off. No complants here.

I used this to compare led lights to fluorescent and cfl lights. Led was at least 1/3 of the watts as fluorescent of same lumens and about 1/2 the cfl. However, the led did not disperse the light as well, led cast a more distinct shadow. now going to try multiple led lights of a smaller lumen for better shadow fill.

I borrowed a P3 International Kill-A-Watt Electricity Usage Monitor from a friend 2 years ago. I recorded electric use on my refrigerator for a month, and then calculated that it costs me $0.14 per day to run it. Some web sites and magazine articles tell you that you should replace an old refrigerator every 10 or 15 years. I think this very easy to use meter proves them wrong and saved me hundreds of dollars. Also, my large 15 year old chest freezer costs $0.09 per day to run. My mother asked me if she should unplug her TV when she isn't using it. Since anything that has a remote uses some electricity when it's not in use I thought it would be good to test the TV for her. I finally bought my own meter. Her TV costs $0.02 per day when it is not in use. It's not worth unplugging it. The reason for the slightly less than perfect rating is the display is not backlit. I needed a flashlight to read it when it was plugged in behind the TV or refrigerator. When you unplug it, it loses its info and starts counting again. Why doesn't Walmart carry this in the store? Lots of people could get good usable info from it.

Received the Kill-A-Watt a few days ago. Simply plug into the wall outlet and plug the appliance into it - voila'; easy to use with simple instructions. Settings for voltage, amps, hertz, and Kilowatts per hour with a duration clock. I've set it to measure KWh and continue to monitor the daily usage of the appliance. This will help me determine if the appliance is a power hog or not. Recommended for those who want to understand their household's electrical usage and those who want to reduce their power consumption.

I found leaks electrical "leaks" all over the house. My FIOS HD box uses ~19 watts even when it's off! This isn't a DVR, just the box you need for HD. It only takes shutting down a few leaks like that to save the price of this Kill-a-Watt.

This device is so easy to use to find the power hogs in your house. I was amazed at how much power was used by each device plugged in an how easy it is to save power and $$$.
