10-Hour PowerBook Battery
Anonymous Coward writes "Valence has apparently caved to pressure from Mac fans and finally released iBook/TiBook compatible cabling for their N-Charge Power System. The N-Charge is a $300, 10-Hour Lithion-Ion battery that powers laptops and cell phones/pdas at the same time. The next step? How about adapters to power my miniDV camcorder?" There's also a lighter version that has about half the power, for half the price.
Yeah, it's called "The iBook Battery" that comes with your iBook, available for $129 from apple. Mine lasts 5-6 hours now on a charge.
