With all the accessories that drain a phone’s battery life, it’s always nice to see one that actually prolongs it. Cabin is a slim, ergonomic attachment for the iPhone that uses the magnetic connection to lock into place and charge without obstructing any of the pivotal iPhone features or even the handheld size of the phone. While this makes for great on-the-go charging, it also works with a custom dock that allows data synchronization and charges both iPhone and Cabin simultaneously. This looks like a convenient way to add more battery life without making the iPhone clunky, but the requirement of a whole new dock just to charge both at once seems a bit much. Cabin will be out in November for $99.
