Abstract

A portable battery DC charger includes a DC power storage having a charging terminal and a discharging terminal, a docking station outfitting the DC power storage to retain the DC power storage at a predetermined orientation, and a utility device integrally provided at the docking station, wherein when the DC power storage is docked at the docking station, the DC power storage is selectively operated to charge the DC power storage at the charging terminal thereof and to discharge the DC power storage at the discharging terminal for charging an internal battery of an electronic device.

Claims

1-22. -22. (canceled)

23. A portable battery DC charger for an electronic device having an internal battery, comprising:

a DC power storage having a charging terminal and a discharging terminal;

a docking station outfitting said DC power storage to retain said DC power storage at a predetermined orientation; and

a utility device integrally provided at said docking station, wherein when said DC power storage is docked at said docking station, said DC power storage is selectively operated to charge said DC power storage at said charging terminal thereof and to discharge said DC power storage at said discharging terminal for charging said internal battery of said electronic device, such that when said electronic device runs out of battery, said DC power storage is adapted to provide electricity to said electronic device through a power transfer cable electrically connecting between said discharging terminal of said DC power storage an said electronic device, so that said electronic device is provided with backup power for operation when said internal battery of said electronic device is exhausted.

24. The portable battery DC charger, as recited in claim 23, wherein said charging terminal and said discharging terminal are provided at top and bottom sides of said DC power storage in such a manner that when said DC power storage is slid into said docking station to electrically couple said charging terminal with said power adapter, said discharging terminal of said DC power storage is available for electrically connecting with said electronic device to charge said internal battery thereof.

25. The portable battery DC charger, as recited in claim 24, wherein said utility device comprises a power adapter extended within said docking cavity of said docking station to electrically couple with said charging terminal of said DC power storage when said DC power storage is docked in said docking station, and an AC adapter outwardly extended from said docking station for electrically connecting an AC external power source so as to charge said DC power storage through said power adapter.

26. The portable battery DC charger, as recited in claim 25, wherein said utility device further comprises an AC-to-DC converting circuit enclosed in said docking station to electrically connect between said power adapter and said AC adapter for converting an AC electrical power to a DC electrical power from said AC external power source to said DC power storage.

27. The portable battery DC charger, as recited in claim 25, wherein said docking station has a top opening and a docking cavity slidably receiving said DC power storage through said top opening so as to retain said rechargeable power storage at an upstanding position.

28. The portable battery DC charger, as recited in claim 26, wherein said docking station has a top opening and a docking cavity slidably receiving said DC power storage through said top opening so as to retain said rechargeable power storage at an upstanding position.

29. The portable battery DC charger, as recited in claim 27, wherein said DC power storage comprises a power indicator indicating a DC power level of said DC power storage.

30. The portable battery DC charger, as recited in claim 28, wherein said DC power storage comprises a power indicator indicating a DC power level of said DC power storage.

31. The portable battery DC charger, as recited in claim 23, wherein said utility device comprises a power adapter extended within said docking cavity of said docking station to electrically couple with said charging terminal of said DC power storage when said DC power storage is docked in said docking station, and a DC vehicle adapter outwardly extended from said docking station for electrically connecting a power outlet of a vehicle so as to charge said DC power storage through said power adapter.

32. The portable battery DC charger, as recited in claim 31, wherein said utility device further comprises a DC-to-DC converting circuit enclosed in said docking station to electrically connect between said power adapter and said DC adapter for converting a vehicle DC power to a DC electrical power from said power outlet of a vehicle to said DC power storage.

33. The portable battery DC charger, as recited in claim 32, wherein said DC power storage comprises a power indicator indicating a DC power level of said DC power storage.

34. The portable battery DC charger, as recited in claim 23, wherein said utility device comprises a power adapter extended within said docking cavity of said docking station to electrically couple with said charging terminal of said DC power storage when said DC power storage is docked in said docking station, and a hand crank power generator rotatably coupling with said docking station for manually generating a rotationally mechanical power so as to charge said DC power storage through said power adapter.

35. The portable battery DC charger, as recited in claim 34, wherein said utility device further comprises a power converter enclosed in said docking station to electrically connect between said power adapter and said DC adapter for converting mechanical power to a DC electrical power from said hand crank power generator to said DC power storage.

36. The portable battery DC charger, as recited in claim 35, wherein said DC power storage comprises a power indicator indicating a DC power level of said DC power storage.

37. The portable battery DC charger, as recited in claim 23, wherein said utility device comprises a carrying clip provided at said docking station for being carried at the same time when said DC power storage is discharged for charging said internal battery of said electronic device.

38. The portable battery DC charger, as recited in claim 37, wherein said utility device further comprises a device holder having a size-adjustable holding cavity positioned in front of said docking cavity for holding said electronic device in said holding cavity, such that said DC power storage is docked behind said electronic device to charge said internal battery thereof.

39. The portable battery DC charger, as recited in claim 38, wherein said DC power storage comprises a power indicator indicating a DC power level of said DC power storage.

40. The portable battery DC charger, as recited in claim 23, wherein said utility device comprises a power adapter extended within said docking cavity of said docking station to electrically couple with said charging terminal of said DC power storage when said DC power storage is docked in said docking station, and a solar energy collector integrally provided at a rear side of said docking station for collecting solar energy so as to charge said DC power storage through said power adapter.

41. The portable battery DC charger, as recited in claim 40, wherein said utility device further comprises a solar energy converting circuit enclosed in said docking station to electrically connect between said power adapter and said DC adapter for converting said solar energy to a DC electrical power from said solar energy collector to said DC power storage.

42. The portable battery DC charger, as recited in claim 41, wherein said DC power storage comprises a power indicator indicating a DC power level of said DC power storage.
