Description
ELECTRONIC CHARGING DEVICE
Background of the invention
Field of the invention
The invention relates to devices used for charging portable electronic equipment. More specifically, the invention relates to portable devices used for charging electronic equipment.
Description of the Related Art
In the past, charging devices for portable electronic equipment, notably cell phones and portable PCs and tablets, have been limited to a so-called power supply which at its input receives 110 or 220 V alternating current, and at its output provides 3, 6, or 12 volts or other level DC current for powering the device.
Such devices did not store energy, but merely converted the energy from alternating current to direct-current.
Brief Summary of the Invention
In the past, users of portable electronic devices suffered from the scarcity of power supplies for recharging their devices while they were away from their home or office. Most notably, even at modern international airports throughout the world, there is an acute paucity of areas for recharging portable devices. It is a familiar sight to see many people sitting on the floor of the airport terminal crowded around one or two power supply outlets which are located at the base of a column or hidden behind chairs in the waiting areas, while needy customers eye the few outlets for the moment one becomes available, so they too have the privilege of sitting on the dirty terminal floor recharging their electronic device. Virtually every passenger in an airport terminal has at least one electronic device which is meanwhile constantly discharging. In some cases there are many thousands of needy customers for each power outlet available. The exception would be for the elite group of travelers who have access to the lounge areas. However, even in the lounge areas, there is a scarcity of outlets.
Once in the plane, again, there is a shortage of power supply outlets for recharging devices, although many passengers are literally using their electronic devices for the entire flight.
This problem repeats itself in other areas other than airports, such as in trains, automobiles, and other waiting areas.
It is therefore an object of the invention to provide a solution to the problem of charging electronic devices while away from the home or office.
It is another object of invention to provide a portable power supply which will allow electronic portable electronic device users to recharge their devices without the need for an electric outlet fixed to a building or present in an airplane or train.
It is a further object of invention to provide a portable charging device which accepts 110 V or 220 V as an input at one end of the device, stores the power internally, and then releases the power in the form of 110 V or 220 V to a plug-in power supply at the other end of the device.

The present invention sets out for the first time a portable device which accepts 110 V or 220 V alternating current input on one side of the device, stores the electronic energy in an internal battery, and outputs the stored electronic energy in the form of 110 V or 220 V alternating current.
The device has a convenient shape such that when the input power is connected on one side and the output plug is connected on the other side, the device maintains a generally rectangular shape.
The device is sized to fully charge a variety of different batteries commonly used in portable devices, such as the iPhone®, the iPad®, other tablets, MacBook® or other devices, and other portable computers.
The device circuitry receives 110 V or 220 V alternating current power, and utilizing a microprocessor internally controls and converts the alternating current into direct-current to be stored in an internal battery. A controller controls the distribution of power to an inverter, which changes the direct-current from the battery back into alternating current to be output at 110 V or 220 V.
In operation, the device can be charged by plugging the input into a standard 110 V or 220 V power supply, such as in a building. When the device is charged, it can be removed from the power supply. Thereafter, it can be transported anywhere the user travels. At such time as the user needs to recharge a portable electronic device, the user will plug into the output of the inventive device the so-called power supply from the electronic device, which requires a 110 V or 220 V alternating current input, and which power supply then transforms the alternating current into direct-current to be sent into the electronic device to charge the battery in the electronic device or to power the device. In this manner, the inventive device allows a user to recharge virtually any portable electronic device at any location in the world, as though they had access to the standard power grid.
The inputs to the device can accept virtually any style of plug. Likewise, the output of the device can also accept virtually any style of power supply input leads. In one embodiment, the device accepts the input and output electrical connectors from Apple® devices.
The result is a portable source of AC power contained in a compact device which is transportable anywhere in the world.
The invention (trade name Chug Plug) mobile power for laptop computers such as Macbook Air® and Macbook® consists of a unique mechanical design of input and output that fits to Apple® laptop computers, as well as a battery pack and three novel electrical circuits: inverter circuit, control circuit, and charging circuit.
The mechanical design is illustrated in Figures 13-18.
1. Mechanical Design and operation :
LED 1, 2, and 3 will illuminate green when the invention 1 (Chug Plug) is powered "on". The LEDs will stay lit for 10 seconds after the power button is depressed. To check the remaining capacity of the invention, depress the power button for less than 3 seconds. The green LEDs will illuminate, displaying the remaining battery capacity.
LED 4 will illuminate orange when the invention is connected to an AC power supply and when it is charging a MacBook 6® or other device. This LED will turn off when the invention is out of power or if the AC Power Supply is disconnected. Remove the two-prong adapter tip from the MagSafe® or other Power Adapter. Align the circular metal post on the MagSafe® or other Power adapter with the plastic grooves on the corresponding piece of the invention (the piece with the two plastic barrels pointing down). Connect the invention to the Apple® AC or other adapter by inserting the two plastic barrels of the invention into the similarly shaped receptacle on the Apple® AC or other adapter. Connect the magnetic DC connector to the MacBook® or other device.
To charge the invention or charge the device of the invention and the Apple® or other laptop computer or device simultaneously:
Remove the two-prong adapter tip from the MagSafe® or other Power Adapter .
Attach the Apple® AC or other power cord 7 to the invention.
Align the circular metal post on the MagSafe® or other Power adapter with the plastic grooves on the corresponding piece of the invention (the piece with the two plastic barrels pointing down).
Connect the invention to the MagSafe® or other Power Adapter by inserting the two plastic barrels of the invention into the similarly shaped receptacle on the MagSafe® or other Power Adapter. Connect the magnetic DC connector to the Macbook® or other device .
Plug the Apple® AC or other Power Cord into an AC outlet. The orange LED will illuminate as soon as the invention begins charging and will remain on until the invention is unplugged from the AC power supply and turned off. The remaining LED's will illuminate green as the invention reaches capacity. Once the 3rd LED is illuminated, the invention has finished charging.
1. Electrical Design :
The circuitry consists of three parts: charging circuit, control circuit, and inverter circuit. They are illustrated in the figures below. The charging circuit is responsible for charging the invention battery. The inverter circuit functions to provide power to the MagSafe® or other power supply from the invention battery. The control circuit controls the battery charging and discharging as well as providing battery protection.
It is to be noted that another unique design of the invention is that AC power can bypass the invention battery if charging the invention battery and laptop simultaneously is desired.
Following is a list of key components in the circuitry:
