What's New about Kobo Sage and Kobo Libra 2

An evolution of SleepCovers, the Kobo Sage PowerCover keeps your eReader luxuriously protected, and delivers on-the-go charging. Just slip your Kobo Sage into its PowerCover with easy magnetic attachment, and it will charge from the built-in battery. While PowerCover keeps your HD touchscreen safe, it also automatically sleeps and wakes the device when you open the cover. If you're pairing your Kobo Sage with Kobo Stylus, the PowerCover has a designated slot to keep your stylus close at hand.
