"COMBO TOUCH for iPad Air (4th generation)" is a protective case for the iPad Air that integrates with a detachable keyboard featuring a precision trackpad. It has a backlit keyboard that automatically adjusts brightness to suit the working environment, a Japanese keyboard layout, and a larger trackpad than previous models, enabling efficient work like a notebook PC. ＜Product Features＞ ■ Trackpad Included The trackpad is precise and larger than the 2020 model. It's easier to operate for those with larger hands, as well as for swiping, scrolling, and double-tapping. Highlighting spreadsheet cells and copying text is easy, and editing documents, operating apps, and creating presentations can be done as quickly and accurately as on a notebook PC. ■ Detachable Japanese Keyboard and Case that Protects Both Sides The Japanese keyboard has a full-size layout with 18mm key pitch for comfortable typing. Using the iOS shortcut keys at the top, you can quickly adjust screen brightness and volume, and launch search tools. When reading, sketching, or watching videos, you can detach the keyboard and adjust the stand to a comfortable viewing angle within a 50-degree range. The soft fabric-covered case protects the front, back, and corners of the iPad Air from impacts, scratches, and liquids. ■ Auto-Adjusting Backlight The keys have a 16-level backlight, allowing you to type clearly even in dark places. The brightness can be automatically adjusted to suit the working environment, and can also be manually adjusted using shortcut keys. ■ Connects with Smart Connector It connects to the iPad Air via Smart Connector, so there's no need to charge the keyboard or pair it. There's space on the side to store and charge the Apple Pencil (2nd generation). When the case is closed, the iPad Air and keyboard automatically go to sleep, and when opened, both turn on.
