The new kit that Apple's selling no longer includes a 30-pin to USB cable, and rather than adding a Lightning to USB cable, Apple has instead opted to ship the kit with no cable and drop the price by $10.
Apple's updated World Travel Adapter Kit includes seven pieces (up from six plus a 30-pin cable) and specifies that it supports outlets in Brazil in addition to North America, Japan, China, United Kingdom, Continental Europe, Korea, Australia, and Hong Kong. Apple has also updated the language specifying which devices the kit is compatible with to reflect its newest products.
The kit is designed to work with iPod, iPhone, and iPad, and is compatible with Apple MagSafe and MagSafe 2 Power Adapters (for MacBook, MacBook Pro, and MacBook Air), 10W and 12W USB Power Adapters, and Portable Power Adapters.The updated World Travel Adapter Kit can be purchased from the online Apple Store for the new lower price of $29. It's also available in many Apple retail locations.
