When you measure the power factor, are you measuring it for the device
in question, or are you measuring the average for the neighbourhood?
A plug-in device can only measure it for the load running through it.

Are you suggesting it somehow compensates for the power factor of the
supply automatically?

Is this a trick question? The supply doesn't have a power factor; only
the load has a power factor.
