Abstract

A desktop USB-charger related product has space to receive an AC power-wire, USB-charger wire, or another charging related wire(s). The USB-charger related product is arranged to be installed on a desk top at a hand-reachable distance from a user by attachment means so that there is no need for the user to bend body or knee in order to charge a device using the charger. The USB-charger related product has at least one USB-port that can supply a desired output-current in the range of from 1.0 A to 12 A and 3.5VDC to 8.5VDC by converting input AC power ranging from 110VAC to 250VAC. The USB-charger product may also incorporate at least one additional device such as an AC outlets, sensor, motion sensor, remote control, time display, LEDs, other lights, a power fail device, a smell device, an audio device, a video device, or other electric or electronic devices.

Claims

1. A hand-reachable desk top USB charger device with a wire arrangement, comprising:

a USB charger including a USB-port for receiving and connecting with a plug-end of a USB wire connected to an external electric or digital device, the plug-end of the USB wire including a plug that is inserted into the USB-port to supply charging current for charging an internal energy storage device of the external electric or digital device;

at least one additional device including at least one of another USB-port, an AC outlet device, a motion sensor device, a time device, a remote control device an infrared device, and LED light device, an integrated circuit, a control device, a sensor device, a power fail device, a color changing status-indicating device, a smell device, a motion device, an audio device, a video device, a cable TV device, an Internet device, a wireless device, an electrical device, and an electronic device, said additional device providing at least one additional function;

a wire arrangement means for arranging the USB wire connected to the external electric or digital device while the plug is inserted into the USB-port for charging of the internal energy storage device of the external electric or digital device, or for arranging an AC input wire for supplying an AC input current from an external power source to the USB charger, by coiling or wrapping the USB wire or AC input wire around a pole within a space in the USB charger, the wire arrangement means including a cover or holder for retaining the USB wire or AC input wire in the wire arrangement means and a mechanism for winding and retracting the wire from the space,

wherein the USB charger includes circuitry for converting the AC input current, which has a voltage of between 110V and 250V AC, into a DC output current of at least 1 Amp and between 3.5V and 8.5V DC,

wherein the hand-reachable desk top USB charger device is arranged to be situated in a hand-reachable position on a desk top during use, the USB charger device including attachment means for holding the USB charger device on the desk top, the attachment means including at least one of the following;

glue, screws, a heavy weight, a catch and hook fastener, Velcro™

, double-sided foam tape, a hook and loop fastener, at least one suction cup, a magnetic fastener, and a movement-preventer so that the USB charger can be reached by a user to charge the electric or digital device without having to bend over to reach the USB charger.

2. A hand-reachable desk top USB charger device with a wire arrangement as claimed in claim 1, wherein the USB charger device has only USB-ports and no AC outlet, LED unit, or other electrical device, and the AC input wire has a gauge of less than or equal to 16.

3. A hand-reachable desk top USB charger device with a wire arrangement as claimed in claim 1, wherein the USB charger device has only USB-ports and at least one AC outlet, and wherein the USB charger device further includes outlet safety or convenience parts and accessories selected from a surge protection device, a remote control device, a master power controller, a sensor device, a current leakage warning device, and an auto shut off device.

4. A hand-reachable desk top USB charger device with a wire arrangement as claimed in claim 1, wherein the USB charger device has only USB-ports, at least one AC outlet, and at least one LED-unit, and wherein the AC input wire has a gauge sufficient to meet safety requirements for a device having AC outlets.

5. A hand-reachable desk top USB charger device with a wire arrangement as claimed in claim 1, wherein the AC input wire has a gauge sufficient to meet safety requirements for a device having AC outlets.

6. A hand-reachable desk top USB charger device with a wire arrangement as claimed in claim 1, wherein the wire arrangement includes elastic, roller, or rotating means to enable extension and retraction of the USB wire or AC input wire by rotating or twisting.

7. A hand-reachable desk top USB charger device with a wire arrangement as claimed in claim 1, wherein the USB charger device has a top on which other objects may be positioned during use so as to save desk top space.

8. A hand-reachable desk top USB charger device with a wire arrangement as claimed in claim 1, wherein the USB charger device is included in an extension cord to be hand-reachably attached to a desk surface.
