An electrical power supplying device for supplying electrical power to a group of electrical appliances located in an environment. The electrical power supplying device includes a power supply cord for plugging into a standard power receptacle by way of a supply power plug, and also a base housing portion having a bottom surface. A power-ring subassembly is supported on the base housing portion, has a central aperture defining the boundaries of a 3D interior volume, and is adapted for supporting a plurality of electrical receptacles and one or more electronic circuits, which are electrically connected to the power supply cord. The power-ring housing portion for covering said power-ring subassembly and having a set of plug apertures, aligned with said electrical receptacles, and allowing appliance power plugs associated with said electrical appliances to plug into said electrical receptacles. The power cord portal allows a group of electrical power cords associated with the group of electrical appliances to enter/exit the 3D interior volume in a bundled manner. The cover housing portion is adapted to cover the central aperture of the power-ring subassembly, and conceal appliance power plugs plugged into the electrical receptacles and appliance power cords associated with the electrical appliances. An appliance power cord management structure is supported through the central aperture, and adapted for taking up and managing excess length of each said appliance power cord passing through said power cord portal. The excess length of appliance power cord for the electrical appliance is measured from the power cord portal to the electrical receptacle on the power-ring assembly into which the corresponding appliance power plug is plugged.
