Hi Cruisers! This is the Kingston Digital MobileLite Wireless Pro. It’s a battery backup for USB devices – iPhones, tablets, Cameras. Let’s say your phone or camera is dying and you can’t get to an outlet – boom! You’ve got this cool little gizmo. And speaking of phones, you can use this to back up your phone. And more importantly for US, you can backup your camera’s SD cards. Of course you can store and stream movies and music, but really the key reason we think you might want this as a cruiser is the photo backup feature.
