output voltage for computer
if the output is 18.5v and i hook up only a 16.5v powe cord to the computer, will it be enough to turn it on
Is this a good question?
Though the 60 W MacBook and 85 W MacBook Pro MagSafe connectors are identical, Apple recommends using only the adapter provided with the machine. The MacBook Air has a smaller 45 W version of the MagSafe adapter. (Note: The 13" MacBook Pro use the 60 W Charger, while the 15" and 17" use the 85 W)
The inner large pin is V+ @ 16.5 VDC. Measuring with no load will give 6.86 VDC; the full 16.5 V is provided to the proper load.
The outer large pin is ground.
The tiny center pin appears to be a charge control pin to change LED color and possibly adapter switch off.
