FAQ for DC Power Adapters:

 

Q. What is "efficiency"?

 

A: Efficiency is the ratio between the useful output of an energy conversion device and the input.  For example, if your computer uses 300W, but pulls 400W from the wall, then the efficiency is 300W/400W, or 75%.

 

 

Q: What is "power factor"?

 

A: Power factor is the ratio of the real power used by a device, to the apparent power used by that device. Real power is the capacity of the circuit for performing work in a particular time and is measured in Watts. Apparent power is the product of the voltage and current of the circuit and is measured in volt-amperage.

Usually, the power adapters do not built in power factor correction circuit for the input power less than 70W and the power factor will is around 0.5 at full load.
