1. An LED desktop light device having at least one USB charging port, comprising:

  • at least one USB charging port installed in a space within a light device housing, said at least one USB charging port having a DC charging current output voltage of 5V±

    20% and an output current of between 1.0 A and 10.0 A, wherein the at least one USB charging port has a charging function;

    at least one first internal circuit inside the LED desktop light housing to supply electrical currents having at least one first voltage that is different than the USB charging current output voltage for (a) an illumination function of the LED desktop light provided by a plurality of LEDs, and (b) at least one added function of the LED desktop light selected from at least one of (i) image, message, or data display, (ii) an alarm or timepiece function, (iii) a wireless controller function to control the plurality of LEDs, (iv) communications, (v) audio, (vi) a cosmetic mirror with magnification function, (vii) a temperature display or air freshening function, (viii) an airflow, humidifier or fan function, (ix) a multiple color LED accent light function, (x) motion, photo, or power fail sensor-triggered control of the plurality of LEDs, (xi) wireless remote control of the plurality of LEDs, (xii) brightness control of the plurality of LEDs, and (xiii) lighting effects setting, adjustment or control of the plurality of LEDs; and

    at least one second internal circuit that is inside the light device housing for converting said first voltage into said DC charging current output voltage for charging an energy storage unit or assembly of at least one other product via a USB connecting wire with a male plug that is plugged into the at least one USB charging port;

    wherein the at least one USB charging port is a built-in, non-detachable charging port that can receive multiple different USB wire and plug configurations to charge different said other products, andthe light device housing includes a base and at least one of a clip, screw, fixing kit, or non-skid pad for installation on a desk or table surface or edge to prevent the LED desktop light from being pulled off the desk or table by gravity or by a pulling force on an AC power supply cord.
