a desk top item housing;
at least one LED in said desk top item housing;
desk top item function means in said desk top item housing for providing at least one of the following functions: a display of light beams from the LED, projection of an image, projection of a time image, clock functions, illumination of an area, playing of music, serving as a source of power or electric signals, display of photos, transmission of digital signals, providing air flow at a desired temperature, generating moisture, steam, or smells, dispensing liquid, brewing coffee/tea, preparing food, and displaying charging status;
at least one USB-unit or USB-module installed within a space in the desk top item housing and powered by a DC or AC source, said at least one USB-unit or USB-module supplying electric power of a desired voltage and current to charge USB devices having USB connectors plugged into at least one said USB-unit or USB-module, said USB-unit or USB-module including components selected from circuitry, an integrated circuit, motion sensor means, switch means, sensor means, timer means, time delay means, a timer, resilient conductive means, transformer means, inverter means, adapter means, PIR means, infrared means, and master power control means, for converting a voltage and current of said DC or AC source into a USB charging voltage and current and for supplying power to different said USB devices; and
