P3 International (Kill-A-Watt) P4400 Kill A Watt Power Meter review

I have not tested the device personally, but asked to read the Paloma Hill review by a friend.\r\n\r\nI read the review in which Hill measured the amps and volts used by a load and found the Kill A Watt meter to be reading low. \r\n\r\nThat is probably because AC power is NOT the product of volts and amps! It is the product of volts, amps and power factor. The power factor of a reactive load like a motor (including refrigerator compressors, AC compressors, furnace fans, etc.) is often 80% (0.80) or so. In other words, the Kill a Watt is accurate and Paloma Hill\'s calculations are wrong.
