Patent attributes
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.
