What is the input voltage range?
Does anyone have (factual) information on what the input voltage specification for the MacBook Air range is?
The powers upplies for the different models vary significantly in output voltage (14..18.6 V) and they have been reported to be interchangeable. How does this work? I understand variable current draws (and therefore variable power ratings). But in order to deal with varying voltages wouldn't the MacBook have to employ some sort of DCDC converter at the input side? If that is true what is the maximum input voltage range, specifically for the 11" MacBookAir?
I am interested in this to understand possible charging options for the MacBook (DIY and or commercial 3rd party)
Is this a good question?
