Customer Rating:
good price, works great. i have solar panels and now i can see what appliance is using the most power. and i can monitor the watts being used,and the timer is great ,i can monitor how long i had my solar system running day and night and calculate the watts being used and the time it was used for,i no how much i saved that weak. all so i had a lot of fun plugging in all my appliance and seeing the watt output and i no what is using energy when item was off,and it will save you some money knowing that. i traded my normal light bulbs for the energy saver bulbs and new what i was saving thanks to this P3 International P4400 Kill A Watt Electricity Usage device.

P3 Kill A Watt Energy Monitor - Excellent Device

Customer Rating:
I had no problems using this energy monitor to evaluate the power and energy consumption of various devices around my house. The main consideration, as has been previously mentioned, is that the energy monitor will block the other outlet in a duplex, so plan accordingly. I also tested the energy consumption of the energy monitor itself by plugging one unit into another and determined that its energy consumption is indeed negligible.

Being employed in power quality for the past 20 years, I know a bit about power monitors. This is a nice cheap device to provide you with your energy consumption. It will also provide you with fairly accurate costs.

It will not provide you with troubleshooting information, such as harmonic, or inter harmonic content. Flicker, or waveforms.

So, if you want to reduce energy costs, this can help you identify devices actual energy cost. If you wish to troubleshoot an electrical problem, you should look elsewhere. A good start would be the Ranger PQ Recorders [...]
