Charging system for mobile device
A mobile device auxiliary battery is disclosed. The mobile device auxiliary battery can supply electric current to the mobile device. A processing device associated with the auxiliary battery may be wirelessly connected to the mobile device, such as with a Bluetooth interface, and thereby control operational aspects of the battery, including for example control over supplying power to the mobile device. The auxiliary battery may be part of a charging system or kit that includes a uniquely designed separate charger or part of a protective case. In yet another aspect, the protective case may include unitary bumper flexible bumper co-molded to the body of the case and a male connector extending from a nested portion that is adapted to tilt outward from the case to facilitate insertion of the corresponding female port on the mobile device into the connector and into the case. The protective case may also include a stand in the form of dock or cradle to allow positioning and/or charging of the battery case and mobile device via external contact terminals correspondingly positioned on the outside of the case and in the cavity of the cradle.
