Portable electrical power unit
First Claim
1. A portable electrical power unit configured to be supported on a desk or table, said power unit comprising:
- a housing defining an interior region, said housing comprising an upper region and a lower region, said upper region having a top surface and at least three upper side surface portions extending downwardly from said top surface, and said lower region having a bottom surface and at least three lower side surfaces extending upwardly from said bottom surface;
wherein a first of said upper side surface portions faces in a first direction, and a second of said upper side surface portions faces in a second direction that is angled at least about 90 degrees relative to the first direction;
first and second electrical outlet openings disposed in said first and second upper side surface portions, respectively, and a charge level indicator opening disposed in said third upper side surface portion;
first and second electrical receptacles mounted in said interior region and accessible through respective ones of said first and second outlet openings, wherein said first and second electrical receptacles are each interchangeably mounted in either of said first and second outlet openings;
a rechargeable electrical power source mounted in said interior region and in electrical communication with said first and second electrical receptacles;
a recharging interface disposed at said lower region of said housing, wherein said recharging interface is in electrical communication with said rechargeable electrical power source and is operable to receive electrical current from an external power source for recharging said rechargeable electrical power source; and
a charge level indicator positioned in said charge level indicator opening and operable to provide a visual indication of a charge level of said rechargeable electrical power source.

Abstract
A portable electrical power unit includes a housing defining an interior region that receives a power source, such as a rechargeable battery or capacitor, and one or more electrical connectors that are accessible at or through outer surfaces of the housing. The housing includes a substantially flat base for resting atop generally horizontal surface, and may include a power switch for selectively energizing the outlets. Optionally, a charging indicator provides a visual indication of the current capacity or charge level of the onboard power source. The power unit may receive or convey electrical power via direct-contact electrical terminals or via inductive power transmission, and may include additional features such as a location-detecting circuit operable to detect and generate a signal in the event that the power unit is moved out of a predefined area.

16. A portable electrical power unit configured to be supported on a desk or table, said power unit comprising:
-
a housing defining an interior region, said housing comprising an upper region and a lower region, said upper region having a top surface and four substantially planar upper side surface portions extending downwardly and each sloping laterally outwardly from said top surface, and said lower region having a bottom surface and four substantially planar lower side surfaces extending upwardly and each sloping laterally outwardly from said bottom surface, wherein each of said upper and lower side surface portions faces a different direction; an opening formed in each of said upper side surface portions; at least three electrical receptacles mounted in said interior region, wherein said electrical receptacles are interchangeably mountable in three or more of said openings formed in said upper side surface portions and are accessible through said openings; a charge level indicator mounted in a fourth of said openings and operable to provide a visual indication of a charge level of said rechargeable electrical power source; a rechargeable electrical power source mounted in said interior region and in electrical communication with said power switch and in selective communication with each of said at least three electrical receptacles; a recharging interface disposed at said lower region of said housing, wherein said recharging interface is in electrical communication with said rechargeable electrical power source and is operable to receive electrical current from an external power source for recharging said rechargeable electrical power source; an interchangeable aesthetic cover coupled to said top surface and forming an uppermost surface of said power unit; and wherein said bottom surface of said housing comprises a panel that is removable to expose said interior region and said rechargeable electrical power source. - View Dependent Claims (17, 18, 19)
