Abstract

A battery case for charging a mobile device received therein includes a housing having a back portion with a generally planar inner surface and an outer surface, and a side wall extending upwardly from the back portion. A battery is disposed within the housing, and a charging connector is stored within the housing in a stored configuration and in electrical communication with the battery. The charging connector includes a flexible tether having a proximal end connected to the housing and a distal end having an adaptor for mating with a connector of the mobile device. The charging connector has an outer surface and a lower surface, where the charging connector lower surface is bounded by a plane of a lower end of the battery case in the stored configuration.

Claims

1. A battery case for charging a mobile device received therein, comprising:

a housing including a back portion having a generally planar inner surface and an outer surface, and a side wall extending upwardly from the back portion;

a battery disposed within the housing; and

a charging connector stored within the housing in a stored configuration and in electrical communication with the battery, the charging connector including a flexible tether having a proximal end connected to the housing and a distal end having an adaptor for mating with a connector of the mobile device, the charging connector having an outer surface and a lower surface, the charging connector lower surface bounded by a plane of a lower end of the battery case in the stored configuration.

2. The case of claim 1, wherein the charging connector outer surface is bounded by a plane of the back portion outer surface in the stored configuration.

3. The case of claim 1, wherein the side wall has a recessed portion at the lower end of the battery case.

4. The case of claim 1, wherein the housing includes a port receiving an external power input for charging the battery in a charging state.

5. The case of claim 4, wherein the port is a micro-USB port.

6. The case of claim 4, further comprising a flexible flap covering the port when in a non-charging state.

7. The case of claim 1, wherein the housing includes a recessed area receiving the charging connector in the stored configuration and including a storage portion receiving the adaptor and a channel receiving the tether.

8. The case of claim 7, wherein the storage portion includes a ledge which provides a gap between the back portion outer surface and the adaptor when the adaptor is received in the storage portion.

9. The case of claim 1, wherein the housing includes a battery check button operably connected to the battery for indicating a level of charge of the battery.

10. The case of claim 1, further comprising an integrated USB connector in electrical communication with the battery for recharging the battery, the connector having a flexible cable configured to nest within the housing.

11. The case of claim 1, further comprising an integrated AC adaptor in electrical communication with the battery for charging the battery.

12. The case of claim 1, further comprising an audio notification module operably connected to the battery for providing an audio indication in response to powering and charging events of the battery case.

13. A battery case for charging a mobile device received therein, comprising:

a housing including a back portion having a generally planar inner surface and an outer surface, and a side wall extending upwardly from the back portion and including a recessed portion at a lower end of the battery case;

a battery disposed within the housing; and

a charging connector stored within the housing in a stored configuration and in electrical communication with the battery, the charging connector including a flexible tether having a proximal end connected to the housing and a distal end having an adaptor for mating with a connector of the mobile device, the charging connector having an outer surface and a lower surface, the charging connector outer surface generally flush with the back portion outer surface and the charging connector lower surface generally flush with the lower end of the battery case in the stored configuration.

14. A two-piece battery case for charging a mobile device, comprising:

a shell portion having a generally planar support portion with a side wall extending upwardly from the support portion, the shell portion receiving the mobile device therein in a receiving state;

a battery portion releasably connected to the shell portion and having an outer surface;

a battery disposed within the battery portion; and

a charging connector stored within the battery portion in a stored configuration and in electrical communication with the battery, the charging connector including a flexible tether having a proximal end connected to the battery portion and a distal end having an adaptor for mating with a connector of the mobile device, the charging connector having an outer surface and a lower surface, the charging connector lower surface bounded by a plane of a lower end of the battery case in the stored configuration.

15. The case of claim 14, wherein the charging connector outer surface is bounded by a plane of the back portion outer surface in the stored configuration.

16. The case of claim 14, wherein the side wall has a recessed portion at the lower end of the battery case.

17. The case of claim 14, wherein the battery portion includes a port receiving an external power input for charging the battery in a charging state.

18. The case of claim 17, further comprising a flexible flap covering the port when in a non-charging state.

19. The case of claim 14, wherein the battery portion includes a recessed area receiving the charging connector in the stored configuration and including a storage portion receiving the adaptor and a channel receiving the tether.

20. The case of claim 14, wherein the battery portion includes a battery check button operably connected to the battery for indicating a level of charge of the battery.
