Description
- This application claims the benefit of U.S. Provisional Application No. 61/521,815, filed Aug. 10, 2011, which is incorporated herein by reference.
- The present invention generally relates to power chargers for electronic devices, and more particularly relates to a portable charger capable of charging multiple electronic devices simultaneously.
- Present day consumers typically own several electronic devices specifically designed for portability and use on-the-go, including, for example, a mobile phone or smart phone, a portable music player like an iPod® or an MP3 player, a tablet, a portable gaming unit, and the like. Each of these devices requires frequent recharging. Such electronic devices typically utilize a cable for connecting the device to a power source, such as a wall outlet, a car charger, an airplane charger, or a computer. However, a separate cable is usually required for each power source. Moreover, different electronic devices often utilize different ports and interfaces such that a single charging cable is not compatible with multiple devices. Accordingly, a tech-savvy consumer, with several electronic devices, will usually have multiple charging cables to keep track of. Even then, the consumer may not always be in a place where a power source is readily available, or even if so, may not have the appropriate cable or adapter available to use with a particular power source.
- With traditional power sources, such as those noted above, it is difficult to charge multiple devices at the same time, especially where each device requires a separate charging cable. For example, a car charger port will only handle a single cable at a time. Adaptor devices are available on the market for connecting multiple devices to a power source at the same time—for example, a two-to-one or three-to-one car charger splitter. However, such adapters are often only compatible with certain interfaces. Moreover, such adapters tend to be bulky.
- Multi-source adapters are also available on the market for making a charging cable compatible with multiple power sources. For example, a charging cable with a traditional plug interface for connecting the cable to a wall outlet could exchange the plug with a car charger interface, or an airplane charger interface, or a standard USB interface. However, for such adapter devices, each of the interfaces is usually a separate piece, and therefore difficult to keep track of when not in use.
- Similarly, interface attachments are also available for adapting a charging cable for use with a variety of devices, each with a different interface. However, such attachments are usually separate pieces, and therefore difficult to keep track of when not is use. Further, use of such attachments does not solve the problem presented by the need to charge multiple devices at the same time, as oftentimes, only one attachment can be used with a charging cable at a time.
- Existing power charger devices also usually cannot charge multiple devices at the same time. Even if multiple devices may be attached to the power charger at the same time, the charger will prioritize how the devices are recharged—i.e., it will charge one device first and then the second. However, this approach risks not having sufficient charge remaining in the charger for fully charging the second device.
- Further, some portable charger devices will not permit recharging from the charger when the charger is itself being recharged or connected to a power source. Such devices require the charger unit to be disconnected from a power source before a charge will be passed on to a device connected to the charger. Also, some such charger devices must be fully charged first before any device connected to the charger unit can be recharged.
- In view of the foregoing, there is a need for a charger that can be used to charge a variety of electronic devices, including but not limited to smart phones, mobile phones, data tablets, music players, cameras, camcorders, gaming units, e-books, Bluetooth® headsets and earpieces, GPS devices, and the like, either individually or collectively in various combinations. Additionally, there is a need for such a charger that is portable and easily used in various conditions and locations to charge one or more electronic devices simultaneously, including but not limited to in a house or office, a car or an airplane. Still further, there is a need for a charger system that is compatible with a personal computer for not only charging one or more electronic device, but also provides a conduit by which data can be exchanged between such devices and a portable computer or an external storage database. Accordingly, it is a general object of the present invention to provide a portable charger that improves upon conventional power chargers currently on the market and that overcomes the problems and drawbacks associated with such prior art chargers.
- In accordance with the present invention, a portable charger is provided for charging one or more electronic devices. In general, a portable charger kit may comprise a portable charger unit combined with multiple connectors for connecting to more than one electronic device, as necessary. For example, the charger unit can include at least one power output for connection to electronic devices via connectors or charging cables, including a squid connector providing multiple connection interfaces adaptable to a variety of electronic devices. Alternatively, the charger unit can include one or more connector cables connected to the charger unit and disposed within the charger housing for connection to electronic devices. Additionally, a portable charger kit may comprise a portable charger unit combined with an adapter unit for recharging the charger unit. Additional cables can be provided in the kit, such as a USB connection cable for connecting the portable charger unit to a computer for recharging or data exchange, without departing from the principles and spirit of the present invention.
- In a first aspect of the present invention, the charger unit comprises a charger housing with a power input and at least one power output. A rechargeable battery is disposed within the charger housing and is operatively connected with the power input (for providing an electrical charge from an external power source for recharging the internal battery when the charge unit is connected to the power source) and the at least one power output (for charging other electronic devices from the rechargeable battery). The charger unit is portable as a result of the small size of the housing. Despite the small size of the unit, the power capacity is very high so that the charger can accommodate multiple electronic devices at the same time. The charger unit further comprises connector means capable of connecting two or more electronic devices to the charger unit via at least one output port.
- In an embodiment of the charger unit of the present invention, one or more connector cables, each having a respective connection interface, is attached to the charger housing and operatively connected to a respective power output of the charger unit. Preferably, the charger housing includes one or more cavity in which each connector cable may be stored, when not in use, and from which each connector cable may be removed when needed for recharging an electronic device. In a more preferable embodiment of the charger unit, the unit includes multiple connector cables each with a respective storage cavity formed in the charger housing, thereby permitting multiple electronic devices to be charged by the charger unit simultaneously.
- In a preferred embodiment of the present invention, the charger unit turns on when it is plugged into an electronic device needing charging. In alternate embodiments, the charger unit may include “shake-to-activate” technology, whereby the unit is turned on by shaking the charger housing. Such technology utilizes an internal switch disposed within the housing that actuates to an “on” position by a quick force - such as the force created by a shake. The switch is operatively connected to a rechargeable battery unit.
- In various embodiments of the present invention, the charger unit may further comprise a controller or processing unit, which can keep track of the capacity level of the battery unit, store data or provide a conduit means by which data can be exchanged between electronic devices, such as between a smart phone and a computer. In an embodiment of the present invention, information regarding the power level remaining in the battery unit is provided by shaking the charger unit.
- In another aspect of the present invention, an adapter unit comprises multiple adapter interfaces for connecting the charger unit or another electronic device to a power source, such as a standard power outlet, a car charger port, an airplane charger port, or a USB interface. In a preferred embodiment, the adapter unit provides an all-in-one charger adapter in a compact, lightweight unit.
- In another aspect of the present invention, a squid connector is provided for facilitating connection of one or more electronic devices to the portable charger unit or another power source. In a preferred embodiment, the squid connector comprises a USB connector adapted to engage a power output port of the portable charger unit or any other device with a USB port; multiple connector interfaces adaptable for various electronic devices; a retractor for extending the length of the cords of the squid connector; and a power indicator for confirming the existence of a power current being supplied through connector cables to the electronic devices to be charged.
- An advantage of providing multiple connector cables—either attached to and included with the charger unit, or attachable to respective power output ports, or provided by a squid connector - is that several electronic devices can be charged at the same time. Moreover, multiple connector interfaces can be designed to attach to and accommodate various types of devices, including smart phones, mobile phones, data tablets, music players, cameras, camcorders, gaming units, e-books, Bluetooth headsets, GPS devices, and the like.
- In another aspect of the present invention, a portable charger unit for simultaneously recharging a plurality of electronic devices, each having a rechargeable internal battery, comprises a charger housing internally storing a rechargeable battery, a power input port operatively connected to the internal battery for recharging the internal battery when the charger unit is connected to an external power source, and a plurality of power output ports operatively connected to the internal battery for charging electronic devices connected to the charger unit via the output ports. The charger unit recharges two or more electronic devices simultaneously when they are all connected to the charger unit via the output ports.
- In another aspect of the present invention, a portable charger kit for simultaneously recharging a plurality of electronic devices, each having a rechargeable internal battery, comprises a portable charger unit and an adapter unit. The kit may further include a squid connector or additional connector cables for connecting multiple electronic devices to the charger unit for simultaneous charging.
- These and other objects, features and advantages of the present invention will become apparent in light of the detailed description of embodiments thereof, as illustrated in the accompanying drawings.

FIGS. 11A , 11B and 11C illustrate planar side views of an adapter unit comprising a part of a portable charger kit in accordance with the present invention. - A portable charger kit in accordance with the present invention is shown in
FIG. 1 , and generally comprises aportable charger unit 10 having a rechargeable internal battery for recharging one or more electronic devices. Theportable charger unit 10 may have a variety of designs, as discussed further below, and may be provided with connector cables and adapters suitable for recharging the internal battery of thecharger unit 10 and recharging the batteries of various electronic devices connected thereto. For example, as shown inFIG. 1 , the portable charger kit may be combined with at least one of anadapter unit 12, as shown inFIGS. 11A-11C , for connecting thecharger unit 10 to an external power source, and asquid connector 14, for connecting one or more electronic devices to thecharger unit 10. Additional connector cables can be provided with the kit, such as aUSB connection cable 16, for connecting theportable charger unit 10 to theadapter unit 12 or separately to a computer for recharging or data exchange, without departing from the principles and spirit of the present invention. - In accordance with intended operation of the portable charging kit, a user can recharge one or more electronic devices using the
charger unit 10, a computer, a wall socket, a car power outlet, or an airplane power outlet. For example, the kit of the present invention can be used to charge smart phones, mobile phones, data tablets, music players, cameras, camcorders, gaming units, e-books, Bluetooth® headsets and earpieces, GPS devices, and the like, either individually or collectively in various combinations. In accordance with another feature of the present invention, the portable charger kit can also be used as a conduit by which data can be exchanged between electronic devices and a portable computer or an external storage database. - Referring to
FIGS. 1 , 2A and 2B, thecharger unit 10 comprises acharger housing 20 with a power input 22 (FIG. 2A ) and at least one power output 24 (FIG. 2B ). As shown inFIG. 2A , thepower input 22 generally takes the form of a mini-USB port, but can take the form of any known interface for connecting a device with a power source, including but not limited to a USB interface, a micro-USB interface, or an AC-to-DC connector interface. As shown inFIG. 2B , two USB ports are provided as power outputs 24. As a result, thecharger unit 10 can be connected to two connector cords and/or devices via the USB ports at the same time. Again, thepower output ports 24 can take the form of any known interface for connecting devices, including but not limited to a mini-USB interface, a micro-USB interface, or the like, and indeed, the twooutput ports 24 need not be the same type of interface. Additionally, thecharger unit 10 can be connected to more than two devices at the same time using thesquid connector 14 included in the portable charger kit of the present invention, as described in further detail below. - In accordance with the present invention, the
charger unit 10 is readily portable as a result of the small size of thehousing 20. Alanyard 25 can be provided for carrying thecharger unit 10. Despite the small size of the unit, the power capacity is very high so that thecharger 10 can accommodate multiple electronic devices at the same time. - Referring to
FIG. 3 , thecharger unit 10 comprises arechargeable battery unit 26 disposed within thecharger housing 20 that can be recharged by connecting thecharger unit 10 to an external power source, such as a computer, a wall socket, a car or an airplane, using a power connecter attached to thepower input 22 of thecharger unit 10. For example, the power connector can be a cable, such as theconnection cable 16 having a mini-USB interface on one end for insertion into theinput port 22 of thecharger unit 10 and a standard USB interface on the other end for insertion into a USB port of a computer. Alternatively, the USB interface of thecable 16 can be inserted into theadapter unit 12 included in the portable charger kit of the present invention, as discussed in further detail below, for connection to a standard power source, such as a wall-socket via a standard U.S. plug or a variety of foreign plug styles, a car charger socket—e.g., a cigarette lighter socket—via a car charger interface, or an airplane charger socket via an airplane charger interface. In preferred embodiments, therechargeable battery unit 26 is preferably a Lithium-Ion battery. - The
rechargeable battery unit 26 is disposed within thecharger housing 20 and is operatively connected with thepower input port 22 for recharging thebattery 26 when thecharger unit 10 is connected to an external power source via thepower input 22. Therechargeable battery 26 is also operatively connected with each of thepower output ports 24 for recharging electronic devices connected to thecharger unit 10 via thepower output ports 24 from therechargeable battery unit 26. - The
charger housing 20 also includes a power indicator means 28 that will indicate not only that an electrical current is being supplied to one or more electronic devices connected to the charger unit, but also what the remaining capacity of theinternal battery 26 in thecharger unit 10 is. For example, in an embodiment of the present invention illustrated inFIG. 1 , the power indicator means 28 comprises a series of four lights, but can include more or fewer lights without departing from the principles and spirit of the present invention. When thebattery 26 is at full capacity, all the lights will be lit up. As the battery power decreases, the lights will correspondingly decrease by one as the power is used—e.g., from four to three to two to one to none. Thus, when thebattery 26 is at half capacity, only two lights will be lit up. If there is no capacity left in theinternal battery 26, none of the lights will be lit up. Alternatively, the power indicator means 28 can comprise a digital interface that provides a battery capacity level for the internalrechargeable battery unit 26, or another known means of providing battery level information. - The
charger housing 20 may include additional indicator means providing separate information for separate functions of the charger unit. For example, separate indicator means can be provided for the power level of the internalrechargeable battery unit 26 in thecharger unit 10 and for the electronic devices attached to thecharger unit 10 via eachpower output port 24. Similarly, the device may use a digital output that provides data regarding the power level of the internalrechargeable battery unit 26 separate from data regarding any electronic device attached to thecharger unit 10 via each of theoutput ports 24. - In a preferred embodiment of the present invention, the
charger unit 10 turns on when an electronic device needing charging is plugged into thecharger unit 10. In alternate embodiments of the present invention, thecharger unit 10 may include “shake-to-activate” technology, whereby theunit 10 is turned on by shaking thecharger housing 20. In further alternate embodiments, thecharger unit 10 can include an on/ off button or switch for activating and deactivating theunit 10, such as the on/offbutton 129 shown inFIG. 4 and on/offbutton 229 shown inFIG. 8 . - As illustrated in
FIG. 3 , thecharger unit 10 includes aninternal switch 30 disposed within thecharger housing 20. In a preferred embodiment, theswitch 30 actuates to an “on” position when a device is connected to thecharger unit 10 via anoutput port 24. In an alternate embodiment, theswitch 30 actuates to an “on” position by a quick force - such as the force create by a shake of thecharger 10. - The power indicator means 28 can confirm that the switch has been turned “on” by lighting up. The
switch 30 is operatively connected to therechargeable battery unit 26. Thecharger housing 20 encloses various electrical components (such as integrated circuit chips and other circuitry) to provide computing operations for the device. The integrated circuitry and other components may comprise a power supply (e.g., the internal rechargeable battery), a microprocessor and controller (e.g., a CPU), memory (e.g., ROM, RAM, flash), a circuit board, a hard drive, and/or various input/output (I/O) support circuitry. The electrical components may also include components for sending and receiving data and media (e.g., antenna, receiver, transmitter, transceiver, etc.). - As illustrated in
FIG. 3 , thecharger unit 10 comprises a controller, including aprocessing unit 32, configured to execute instructions and to carry out operations associated with thecharger unit 10. For example, theprocessing unit 32 can keep track of the capacity level of thebattery unit 26, store data or provide a conduit means by which data can be exchanged between electronic devices, such as between a smart phone and a computer. Theprocessing unit 32 communicates with thebattery unit 26 to determine how much capacity is remaining in thebattery 26. Upon determining the capacity level, theprocessing unit 32 communicates with the power indicator means 28 to provide the user with the appropriate signal for showing how much capacity is remaining in the internalrechargeable battery unit 26—e.g., two out of four lights indicates a half-full battery. In an alternate embodiment of the present invention, the power indicator means 28 can activate to show the power level in theinternal battery 26 using the “shake-to-activate” technology—i.e., information regarding the power level remaining in thebattery unit 26 may be provided by shaking thecharger unit 10. In still further embodiments, indicator means can be provided to show the battery capacity level of one or more electronic devices connected to thecharger unit 10. - The
processing unit 32 also includes a smart interface to determine the total current required for the specific devices connected to thecharger unit 10. For example, if two devices are connected to thecharger unit 10 via each of theoutput ports 24, theprocessing unit 32 will assess how much power is needed to fully charge each of the devices and efficiently allocate an appropriate current to each of the devices at anode 34 so that each device can be charged in the shortest amount of time without interfering with the charging operation of the other device or without overloading the capacity of thecharger unit 10. Similarly, if four devices are connected to thecharger unit 10 via asquid connector 14, theprocessing unit 32 will likewise assess how much power is needed to fully and efficiently charge each of the devices. In this regard, theprocessing unit 32 operates in connection with the input/output (I/O) support circuitry to control interactions with devices connected to thecharger unit 10. The I/O support circuitry may be integrated with theprocessing unit 32 or may be a separate component. Generally, the I/O support circuitry operates by exchanging power (and possibly data) between thecharger unit 10 and electronic devices connected thereto via theoutput ports 24. - The
processing unit 32 also preferably includes a timer for automatically turning thecharger unit 10 off if there is no device attached to theunit 10 for a predetermined period of time. In this regard, the capacity of thebattery 26 can be preserved. Upon shut down of thecharger unit 10, the power indicator means 28 will indicate that thecharger 10 is being turned off—for example, the lights will provide a sequential blinking signal. - The
processing unit 32 further includes astorage unit 36 that provides a place to hold data or instructions for operation of thecharger unit 10 andrechargeable battery unit 26, or data exchanged between thecharger unit 10, a computer, and electronic devices connected to thecharger unit 10, or memory needed for further operations of thecharger unit 10. - Referring again to
FIG. 3 , thecharger unit 10 can include communications components for sending and receiving data and media. For example, anantenna 38 is provided in connection with atransceiver 40, or a receiver and transmitter (not shown), for communication over a wireless communication link. Components of transceivers, receivers, and transmitters are generally well known in the technical field, and thus are not further discussed herein. - The
charger unit 10 of the present invention is adaptable to recharge an electronic device connected to thecharger unit 10 directly from the internalrechargeable battery unit 26 or alternately from a power source to which thecharger unit 10 is connected. Thus, thecharger unit 10 can be a conduit through which a charge is provided from a standard power source, such as a wall socket, a car charger socket, an airplane charger socket, or even a computer. In this situation, the power charge bypasses theinternal battery unit 26. Indeed, in a preferred embodiment of the present invention, a charge provided from a standard power source can recharge theinternal battery unit 26 simultaneously with one or more electronic devices connected to thecharger unit 10. Additionally, theportable charger unit 10 can be disconnected from a standard power source, even when electronic devices are connected to thecharger unit 10, and continue to recharge the electronic device from theinternal battery unit 26 without interfering with the recharging process. For example, the charge switches from the external power source to theinternal battery unit 26 as necessary. - An alternate embodiment of the charger unit is illustrated in
FIGS. 4-7 . As shown, thecharger unit 110 comprises acharger housing 120 having twoconnector cables charger unit 110 to connect respective electronic devices to thecharger unit 110 to be recharged from an internalrechargeable battery unit 26. As shown, thecharger unit 110 further includes a power indicator means 128 (comprising three lights) and an on-off button 129, each operatively connected to the internal functional components and electrical circuitry for operating thecharger unit 110. The internal functional components and electrical circuitry, including the internal rechargeable battery unit and a processing unit, operate similarly to thecharger unit 110 shown inFIGS. 1-3 and discussed above. - Preferably, the
connector cables charger housing 120 and the output ports, although alternate embodiments may include connecter cables that are removable and replaceable so as to permit different connection interfaces to be used with thecharger unit 110.Storage cavities charger housing 120 for receiving theconnector cables FIGS. 4 , 6A-6B and 7B illustrate theconnecter cables charger housing 120 in a non-use condition. By comparison,FIG. 5 shows theconnector cables storage cavities - Referring again to
FIG. 5 , theconnector cables distal end 156 having a connection interface 158. For example, onecable 125 a comprises aUSB connection interface 158 a, while theother cable 125 b comprises amicro-USB connection interface 158 b. Thecables cables connector cables charger housing 120 for attaching theconnector cables charger housing 120. - The
connector cables charger housing 120 to connect to an electronic device during use of thecharger unit 110. Thestorage cavities channels 152 to receive acord portion 162 of each of thecables charger housing 120. - The distal ends 156 of the
connector cables head 164 at the end of therespective cord portion 162 that is received within arespective storage cavity charger housing 120. Preferably, the shape of thehead 164 complements the storage cavity to provide a sleek look to thecharger housing 120 when theconnector cables head 164 andcord portion 162 of eachcable storage cavity connector cables storage cavities - Referring to
FIG. 7A , thecharger housing 120 further includes apower input port 122 for connecting thecharger unit 110 to an external power source to recharge the internal rechargeable battery unit. As shown, thepower input port 122 comprises a USB port, but can take the form of any known interface for connecting a device with a power source, including but not limited to a mini-USB interface, a micro-USB interface, or an AC-to-DC connector interface. - In an alternate embodiment of the
