I've had good luck with a Kensington set of adapters for a G4 15" Al Powerbok and an old G3 Pismo. The Kensington comes with a bunch of adapters for ac and car/empower along with changeable tips for various powerbooks. I have used this on several 15 hour flights to Tokyo or Hong Kong just fine. Check the product description to be sure your PBook and Empower are both listed. I think it was under $50 3 years ago, but there must be new versions. Froogle Empower Kensington Powerbook. Aloha!
