90w Car adapter from 75w airplane limit?
07/19/06 20:38 Filed in: Magsafe adapter
There have been some misunderstandings about getting 90w when there is only 75w available from the airplane...
The Car adapter supplies up to 90w of power if demanded; it is impossible to get 90w if there is only 75w available, but there is a tremdus amount of energy wasted converting from DC to AC, then BACK to DC... You've lost several wattage points just simply converting from DC to AC right off the bat. Therefore, there's a better chance that you'll be better performance with a direct DC to DC solution in an airplane as opposed to using an inverter.
This Car adapter has an adjustable voltage output, use can adjust voltage output from 15v all the way up to 24v (I don't recommend using anything over 18v though).
User need not return their old 85w Magsafe Apple adapter, however, it'll cost you $90.00.
