SPECIFICATION

RELATED APPLICATION

The present invention relates to portable chargers for mobile devices having a light source readily available, and more particularly to multi-functional portable chargers for powering and charging all devices using any and all types of DC or AC electrical sockets and plugs found throughout the world.

FIELD OF THE INVENTION

The present invention relates to portable chargers for mobile devices having a light source readily available, and more particularly to multi-functional portable chargers for powering and charging all devices using any and all types of DC or AC electrical sockets and plugs found throughout the world.

BACKGROUND OF THE INVENTION

Mobile charging cords are designed to be inserted in a cigarette lighter outlet. Cigarette lighter outlets provide a 12+ volt maximum, 15 amp power supply within a vehicle. 12V power fluctuates from 12.5V when not charging to around 14.5V when the alternator is charging and can drop to 5V-6V when the engine is started. DC to DC converters compensate for the fluctuations. Trucks use a 24V electrical system. Aircraft use a 28V electrical system. Most vehicles have only one cigarette lighter outlet. DC charging cords use this power supply to power and charge mobile devices, portable electronic devices, PDAs, lights, fans, heating devices, coolers, motorized tools, music players, cell phones, vacuum, etc.

U.S. 12V automobile plugs use the “UL2089” standard. Sockets and plugs are defined in the ANSI/SAE J563 specification. Spec J563 describes the socket as a cigar lighter. The “cigar” lighter plug’s contact point has a positive voltage and the outer part has a negative voltage. The U.S. size A 12V cigar lighter socket has an inside diameter of 20.93mm - 21.01mm and the plug has a diameter of 20.73mm - 20.88mm. The European size B 12V cigar lighter socket has an inside diameter of 21.41mm - 21.51mm and the plug has a diameter of 21.13mm - 21.33mm.

Different mobile devices have different charging voltages and different charging tips, plugs and sockets. When charging different types of cellular phones or mobile devices, a different charging cord is usually required for each device. An exact charging voltage and charging connection (plug or socket) is required for each specific device. When connecting a charging cord to a device at night, it is difficult to see the connection port while inserting the plug into the device and the orientation of the plug end for insertion into the device. Charging cords are used often in a vehicle and are usually left in plain sight. Flashlights are usually left in the glove box or trunk. At night, if a right-handed driver, when seated in the driver seat, uses the overhead light to illuminate the car interior while they are writing something, the right hand produces a shadow over what they are writing, making it difficult to see what they are writing. Changing a tire or performing some other type of action alone at night requires a third hand to hold a flashlight. The multitude of electric outlets found throughout the world in residential or commercial locations use different voltages, different hertz current (cycles per second) and require different adapter plugs for a device to work using a voltage or hertz current it was not designed to be powered or charged with.

The present invention addresses the above identified problems by providing multiple embodiments which independently or all together eliminate these problems.

SUMMARY OF THE INVENTION

Accordingly, the present invention comprises methods and apparatuses for providing an illumination source while using a multi-functional charging cord or cigarette lighter charging cord to power and charge all devices. The preferred charging cord includes a cable with at least two wires, a standard voltage or multi-voltage regulator cigarette lighter plug on one end for insertion into a cigarette lighter power supply outlet for converting the supplied power voltage into the required DC voltage, and a socket connecting means on an opposite end with preferably at least one illumination source preferably facing outward on or in the socket housing. The standard voltage or multi-voltage regulator plug end also can also include an AC outlet DC conversion plug socket for plugging the charging cord into any AC voltage power source. The multi-voltage regulator embodiment provides DC voltages ranging from 1 volt to 12+ volts, depending on the continuous and maximum voltage output of the cigarette lighter socket or the AC voltage plug outlet DC voltage conversion socket. Some of the standard battery voltages for mobile device batteries are 1.5V, 2.4V, 2.5V, 3V, 3.6V, 3.7V, 4.5V, 5V, 6V, 7.2V, 7.4V, 7.5V, 9V, 9.6V, 10V, 12V, 12-24V, etc. Batteries are usually charged with a 1V to 2V increased voltage than the voltage output of the battery. A 3.6V or 3.7V cellular phone battery is usually charged at around 5V. A vehicle alternator charges a 12V battery at around 14V to 15V. A cigarette lighter socket may provide more than 12V of power produced by a vehicle’s alternator. The illumination source on or in the socket end housing can be turned on or off and may be powered internally or by the connected device. In the multi-voltage regulator embodiment, a third wire can power the illumination source independently. Multiple types of plug tips or socket tips for insertion into the illumination source socket end housing can be interchanged for powering and charging every type of device. Charging plugs and sockets include and are not limited to a two or three prong AC outlet plug (only U.S. 110V-120V shown), a secondary illumination source plug, a two or more cigarette lighter socket splitter plug, a male charging tip plug, a female charging tip plug, a communications charging tip plug, a communications socket plug, etc. Another embodiment includes an illumination source located on the outer housing of the cigarette lighter plug, letting a user know when it is plugged in and when the charge is complete. Further, exemplary embodiments include an illuminated multi-voltage regulator display for showing the voltage supplied to the illumination source socket end connecting means.

Using the preferred embodiment shown in Fig 1B, allows replacing either end of the charging cord with any type of powering or charging means. DC voltage to AC voltage converters or AC voltage to DC voltage converters include Type A, Type B, Type C, Type D, Type E, Type F, Type G, Type H, Type I, Type J, Type K, Type L and Type M plugs or outlets including 110V, 115V, 120V, 127V, 150V, 160V, 175V, 220V, 230V, 231V, 240V, 250V, 280V, etc. AC voltages and 40Hz, 50Hz or 60Hz AC power frequencies. The disclosed embodiments will allow any type of device or any type of power source to power or charge any type of device.

A multitude of modifications and enhancements can be made to the methods and apparatuses for providing an illumination source while using a multi-functional charging cord or cigarette lighter charging cord for powering and charging all devices without departing from the spirit and scope of the invention as a whole.
