The World Travel Adapter Kit includes a set of six AC plugs with prongs that fit different electrical outlets around the world. For world travelers, this is the perfect kit to ensure power connectivity in most countries you may travel to. The Kit is designed to work with (and requires) the white portable power adapter that ships with iBook, MacBook, MacBook Pro, and PowerBook G4, and it also works with the iPod USB Power Adapter and iPod FireWire Power Adapter (available separately). The AC plugs included in the World Travel Adapter Kit directly support outlets in North America, Japan, China, United Kingdom, Continental Europe, Korea, Australia, and Hong Kong.
