Just flip the cover open to power-up and make a Bluetooth connection, then set your device into the integrated stand—you'll be typing in seconds. Shutting down is just as fast. Simply close the cover to turn off the keyboard—it's that easy. The rechargeable battery provides up to 6 months of usage on a single charge.
