Kill a watt, how accurate?
Wanting to know just how much power the window shaker uses, I bought a Kill a watt. It's been to cold to test the AC but most things I have tested are under the rated watts. The 1875w hair dryer w...

Let's add to your list of items requiring VA measurement. Virtually all electronics circuits that have an ac plug, have an ac to dc conversion that uses a diode/capacitor to get 170V dc (peak charge). These circuits have a non-linear current draw and therefore require the VA setting on the meter. TV's, converters, power supplies, and ac wall worsts will give an incorrect value when measuring watts.

The VA feature is more useful than watts when trying to determine inverter draw/loads.
VARS incorporated.
Anything with a transformer, a coil, capacitor, meaning a reactive load needs to be measured in VARS and volt-amps is the way to do it.
A nail hit square on the head - amigo. Gracias
