The multipurpose Spare Battery Charging System is the perfect way to charge your battery while exploring the capabilities of your Galaxy Note™ handset. As the supplied spare battery charges (standard 2500 mAh battery included), your phone can sit snugly in the stand at an optimal viewing angle in horizontal/vertical orientation. Whether you are watching a movie or reading the news, your handset is perfectly positioned. When you are on the go, the charging unit closes, converting to a compact, carrying case for your spare battery so you're never left stranded with a dead battery.
