Apple Travel Companion
The Kensington iPod/Notebook DC Power Adapter makes it easy to power and
charge an Apple PowerBook, iBook, or iPod from any cigarette lighter or
Empower™ port. The super-sleek supply profile is up to 60% smaller* and
70% lighter than other chargers, making it a welcome addition on any road
trip. With the included tips and socket adapter, power is only as far as
the next DC power supply. *by volume
