Tools and Hardware Reviews of P3 International P4400 Kill A Watt Electricity Usage Monitor

Customer Review: BUEN MONITOR DE CONSUMO
Summary: 5 Stars

I could reduce my electricity consumption using this equipment.

Corrected power factor of my pump, refrigerator and change my video card for another of less consumption.

Save 50-70 kbh monthly and down but when change 2 monitors crt.

Customer Review: Bad design - did the engineers even use this themselves?
Summary: 2 Stars

The concept of this device is great. But the reason for the low ratings is that this particular model is designed in a way that limits where you can plug it into or next to. This is because of the location of the three pronged plug on the back of the device (i.e. it is too far away from the bottom of the device).

So, I cannot plug it in if there is already something else plugged into one of the outlets! Are you kidding me?

You will also have problems with certain surge protectors, depending on how they are designed.

So, my question is, did the engineers even use this product?

I need to research other devices like this, because I know they make ones that fit it more situations. If anybody has any suggestions, I would love to hear them.

Customer Review: Bad documation
Summary: 3 Stars

There is no information on how to use this device. I found some info on the web.

Customer Review: Badly Needs Two Improvements
Summary: 2 Stars

I agree with many of the other reviewers. The electrical prongs need to be moved closer to the edge of the unit so it doesn't block the second outlet of the wall plug. The Kill A Watt also needs a backlight. It's virtually impossible to see if the units are Watt or VA (both operated by the same function button) without getting down on the floor with a flashlight. The device does provide the data it advertises, but it's very hard to read the values and know what function is being displayed.

Customer Review: Best Money I have spent on Amazon
Summary: 5 Stars

I am just so pleased with this Kill A Watt unit. It has been fun to use and and investigate all my power consumption. Some things are just for infomational purposes because I can't unplug them(i.e. Refridgerator) and others are devices where we can change our habits some and start savinfg some real money every month.

Pros: Easy to use, inexpensive, small profile,

Cons: Setting disapear when unplugged, zero directions


I think that the company that made this unit could be more helpful if they were to offer a spreadsheet on their website that people could download and use for figuring out their power consumption. I made one myself but it took a lot of time. Also not everyone is good at math and formulas it would be helpful if they offered a small cheat sheet for people to use to help them get started on the math of KWH and how we are all bileed for our electricity.
