The said USB charger only has charging function no any data transmit and only have one input power source not more than one and charging capacity minimum 1.0 Amp up for quickly charge from USB-Charging-ports by 2 male USB-plugs' USB-wire to the device's female USB-ports.

First claim

I claim:

1. An LED desktop item having at least one built-in USB port to charge an energy storage unit of another electric or digital data device, comprising:
a plurality of LEDs installed in the desktop item and arranged in an array, matrix, or lines, or on a printed circuit board, or in a detachable LED bulb, to provide area illumination;
a power cord with an AC plug for supplying AC power to a built-in AC-to-DC circuit of the LED desktop item, or for supplying DC power to the LED desktop item through an external transformer; and
at least one built-in DC-to-DC circuit for changing a first DC current supplied by the AC-to-DC circuit or the external transformer into at least one second DC current, the first or second DC current including (1) a USB current for a USB charging output by the built-in USB port, (2) a DC current for supply to the LEDs, and (3) a DC current for powering at least one additional function of the LED desk top item,
wherein:
the at least one additional function is selected from:

(i) playing music,
(ii) receiving and delivering audio signals,
(iii) providing, at a predetermined temperature, air flow, moisture, steam, odor, or liquid,
(iv) providing an additional night or accent light,
(v) utilizing at least one additional LED as an indicator or charging status light,
(vi) illuminating a cosmetic mirror, and
(vii) supplying power to additional female plug receiving ports, and
the desktop item is installed near a location where persons stay for a period of time, the location including a desk, table, bed, chair, or lawn,
said USB charging output has a current of between 1.0A and at least 5A to provide a charging function for said another electric or digital data device, a DC current input of said USB port being connected exclusively to the external transformer, the AC-to-DC circuit, or the DC-to-DC circuit and not to a battery, and
wherein the at least USB port has a charging function only and lacks a data transfer function.

2. An LED desktop item having at least one built-in USB port to charge an energy storage unit of another electric or digital data device as recited in claim 1 , wherein the at least one USB charging port includes a plurality of USB charging ports having different output power to charge many different electric or digital data devices.

3. An LED desktop item having at least one built-in USB port to charge an energy storage unit of another electric or digital data device as recited in claim 1 , wherein the LED desktop item has at least one built-in AC outlet-port to supply AC current through a conductive piece or assembly without any additional circuitry or electric controller.

4. An LED desktop item having at least one built-in USB port to charge an energy storage unit of another electric or digital data device as recited in claim 1 , wherein the LED desktop item has space to accommodate a large number of USB ports, AC outlet ports or both USB ports and AC outlet ports to supply power simultaneously to a plurality of users in a public area.

5. An LED desktop item having at least one built-in USB port to charge an energy storage unit of another electric or digital data device as recited in claim 1 , wherein the USB port is arranged to receive a plurality of different types of USB plug.

6. An LED desktop item having at least one built-in USB port to charge an energy storage unit of another electric or digital data device as recited in claim 1 , wherein the USB port is included in a rotating unit which has more than one surface, each surface having a different function.

7. An LED desktop item having at least one built-in USB port to charge an energy storage unit of another electric or digital data device as recited in claim 1 , wherein the said LED desktop item is an LED reading or accent lamp.

8. An LED desktop item having at least one built-in USB port to charge an energy storage unit of another electric or digital data device as recited in claim 1 , wherein the another electric or digital data device has a built-in energy-storage unit or assembly including rechargeable batteries, and is one of an MP3 or MP4 player, a smartphone, a computer, an iPhone™, an iPad™, a video game, digital visual equipment, communication equipment, a consumer electric product, and a power bank.

9. An LED desktop item having at least one built-in USB port to charge an energy storage unit of another electric or digital data device as recited in claim 1 , wherein the at least one USB charging port is supplied with power from said AC-to-DC circuit that converts said AC power into a USB charging output, the AC-to-DC circuit including a transformer or invertor or adaptor.

10. An LED desktop item having at least one built-in USB port to charge an energy storage unit of another electric or digital data device as recited in claim 1 , wherein the USB port or another function of the LED desktop item is turned on or turned off by a switch, sensor, timer, photosensor, motion sensor, time delay, master control power kit, remote controller, infrared controller, or wireless controller.

11. An LED desktop item having at least one built-in USB port to charge an energy storage unit of another electric or digital data device as recited in claim 1 , wherein the USB port has a removable or movable cover to prevent kids, dust, or water from getting into the USB port.

12. An LED desktop item having at least one built-in USB port to charge an energy storage unit of another electric or digital data device as recited in claim 1 , wherein the USB port is included in a UL listed or test-lab approved USB-unit or USB-module having built-in prongs and which is adapted to be detached from a housing of the desktop item and carried away by a user.

13. An LED desktop item having at least one built-in USB port to charge an energy storage unit of another electric or digital data device as recited in claim 12 , wherein the USB-unit or USB-module is adapted to be reassembled to the desktop item's housing by a connector or adaptor.

14. An LED desktop item having at least one built-in USB port to charge an energy storage unit of another electric or digital data device as recited in claim 12 , wherein the USB-unit or USB-module has its own safety certification and as a result is adapted to be sold and used separately from the desktop item without additional safety testing.

15. An LED desktop item having at least one built-in USB port to charge an energy storage unit of another electric or digital data device as recited in claim 12 , wherein the USB-unit is an electric charging unit having USB female receiving ends to receive a USB wire's male-plug.
