So I am planning to install a dismantled iBook into my car. And I was wondering if the P2140 would have enough juice to power the old IBook G4. I'm wondering because my AC adapter says it outputs 24v at 2.7A. And I know that the P2140 can Only do 12v, 18.5v o 20v. And I was hoping to also be able to power the lilli off the P2140.

Thanks, Alex
