This is the case that enhances an iPad’s utility with a wireless keyboard and a battery pack that extends the duration of unplugged performance. The keyboard connects wirelessly via Bluetooth, and is built with responsive “island-style” keys that supply the crisp spring-back essential to touch typing. Designed for second- third- and fourth-generation iPads, the case has an integral 4,000 mAh lithium polymer battery that lasts 90 hours on a full charge. An iPad connects to the battery via its 30-pin to USB cable, while the battery recharges using the included USB charging cable. Made of sturdy ABS plastic.
