Electrical power supplying device having a central power-hub assembly supplying electrical power to power plugs, adaptors and modules while concealed from view and managing excess power cord during power supplying operations

1. An electrical power supplying device for supplying alternating current (AC) electrical power and direct current (DC) electrical power to a group of electrical appliances located in an environment, wherein each said electrical appliance has a power cord routed through an environment and into said electrical power supplying device and terminating with an appliance power plug, said electrical power supplying device comprising:

a power supply cord for plugging into a standard power receptacle by way of a power supply plug, and supplying AC electrical power to said electrical power supplying device;

a housing base portion having a central aperture providing access to a 3D interior volume having a capacity for holding a plurality of power adapter modules and/or power adapter blocks associated with said group of electrical appliances located in said environment which can be loaded into said 3D interior volume through said central aperture;

a bottom support surface disposed opposite said central aperture, and on which the power adapter modules and/or power adapter blocks can be supported within the 3D interior volume;

a central power-hub assembly supported generally within a central portion of said housing base portion, extending above the bottom support surface within the 3D interior volume, and adapted for supporting a plurality of internally-disposed alternating current (AC) electrical receptacles and one or more electronic circuits, including an AC-to-DC power conversion circuit, which are operably connected to said power supply cord, and

wherein when the power plugs of said power adapter modules are plugged into said internally-disposed AC electrical receptacles, said power adapter modules can be supported on said bottom support surface, while said power adapter modules and excess power cord are stored and contained within said 3D interior volume;

a housing cover portion for closing off said central aperture and covering said central power-hub assembly and said housing base portion and concealing said power plugs and said one or more power adapter modules supported and stored within said 3D interior volume;

wherein said central power-hub assembly further supports at least one externally- disposed AC electrical receptacle that is accessible and adapted to receive the electrical power plugs of electrical appliances to supply AC electrical power thereto when said housing cover portion closes off said central aperture;

wherein said central power-hub assembly further supports at least one externally- disposed USB direct current (DC) power port that is operably connected to said AC-to- DC power conversion circuit and accessible and adapted to receive the electrical power plug of at least one electrical appliance to supply DC electrical power to the electrical power plug when said housing cover portion closes off said central aperture; and a power cord portal formed in at least a portion of said housing base portion, to allow a group of electrical power cords associated with said group of electrical appliances, to enter/exit said 3D interior volume in a bundled manner;

wherein said central power-hub assembly comprises a central post structure further having a top surface through which said externally-disposed electrical power receptacle and said at least one externally-disposed USB power port are supported;

wherein said housing cover portion includes a first set of apertures for allowing an electrical plug to be plugged into said externally-disposed electrical power receptacle and said at least one externally-disposed USB power plug into said at least one external USB power port;

wherein said housing cover portion further comprises at least one USB power port aperture spatially aligned with at said least one externally-disposed USB DC power port, through which a power plug associated with an electrical appliance can be plugged to receive DC electrical power;

wherein said housing base portion further comprises a first set of air vents for passage of cool air from a first region in said ambient environment into said 3D interior volume; and

wherein said housing cover portion further comprises a second set of air vents for passage of warmed air from within said 3D interior volume to a second region within said ambient environment.

2. The electrical power supplying device of claim 1 , wherein said power cord portal is formed in said housing base portion, allowing the passage of electrical cords through said power cord portal.

3. The electrical power supplying device of claim 1 , wherein said housing base portion is adapted for support on a horizontal support surface.
