Description
- This application claims the benefit of U.S. application Ser. No. 13/682,985, filed Nov. 21, 2012, U.S. application Ser. No. 13/571,992, filed Aug. 10, 2012, and U.S. Provisional Application No. 61/521,815, filed Aug. 10, 2011, which are 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 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 electronic devices to the charger unit via at least one output port.
- In an embodiment of the charger unit of the present invention, multiple 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, thereby permitting multiple electronic devices to be charged by the charger unit simultaneously. Preferably, the charger housing includes multiple cavities in which each connector cable may be stored, when not in use, and from which each connector cable may be removed and flexed when needed for recharging an electronic device.
- In another embodiment of the charger unit of the present invention, a connector cable can be provided with the charger that has two connection interfaces for connection with a respective electronic device in need of recharging. The connector cable can be operatively connected to a power output of the charger unit, permitting multiple electronic devices to be simultaneously charged from a single power output. Preferably, the charger housing includes a cavity in which the connector cable and its two connection interfaces, may be stored when not in use, and from which, the connector cable may be removed and flexed when needed for recharging one or more electronic devices.
- 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.
- An advantage of providing multiple connector cables—attached to and included with the charger unit—is that several electronic devices can be charged at the same time. Moreover, multiple connector interfaces can be designed to be interchangeably used with the connector cable(s), and when used, 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. Still further, each connector cable can be removable from the charger housing and replaced by a different connector cable with a different connection interface.
- 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.

FIG. 12 shows schematically an internal configuration of the portable charger unit ofFIG. 6 . - A portable charger in accordance with the present invention is shown by
FIGS. 1-4 and is generally designated byreference numeral 110. Theportable charger 110 is designed for on-the-go charging of portable electronic devices when a standard power source is not readily available. In this regard, thecharger unit 110 is equipped with a rechargeable internal battery and with connection means that are operatively connected to the rechargeable battery for recharging one or more electronic devices connected to thecharger unit 110 by such means. - The
portable charger unit 110 may have a variety of designs, as discussed further below, and may be provided withconnector cables charger unit 110 and for recharging the batteries of various electronic devices connected thereto. For example, the portable charger kit may be combined with at least one of an adapter unit, such as described and shown in co-pending U.S. application Ser. No. 13/801,338, which is incorporated herein by reference, for connecting the charger unit to an external power source, and a connector cable, for connecting one or more electronic devices to the charger unit, such as described and shown in co-pending U.S. application Ser. No. 13/571,992, which is incorporated herein by reference. - In accordance with intended operation of such a portable charging kit, a user can recharge one or more electronic devices using the charger unit, and can in turn recharge the
charger unit 110 from 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. - Still referring to
FIGS. 1-4 , and also to a schematic of internal components as shown byFIG. 5 , theexemplary charger unit 110 comprises acharger housing 120 with apower input 122 and at least twopower outputs 124, withconnector cables charger unit 110 to include connector cables that are attached to and stored with thecharger housing 120 and thus less susceptible to be lost as is often the case with charging cables that are separate from both a charger unit and an electronic device with which the charging cable is used. Accordingly, as illustrated inFIGS. 2-5 , twoconnector cables power output ports 124 of thecharger unit 110 to connect respective electronic devices to thecharger unit 110 to be recharged from an internalrechargeable battery unit 126. 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. - Referring to
FIG. 5 , thecharger unit 110 comprises arechargeable battery unit 126 disposed within thecharger housing 120 that can be recharged by connecting thecharger unit 110 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 122 of thecharger unit 110. For example, the power connector can be a charging cable having a standard USB interface on one end for insertion into theinput port 122 of thecharger unit 110 and a similar USB interface on the other end for insertion into a USB port of a computer. Alternatively, the USB interface of such a cable can be inserted into an adapter unit included in the portable charger kit of the present invention or separately supplied 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. Still further, a charger unit in accordance with the present invention can include a power input interface, such as a wall plug interface as illustrated inFIG. 6 and described further below. - The
charger unit 110 also can include communications components for sending and receiving data and media. For example, anantenna 138 is provided in connection with atransceiver 140, 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. - In preferred embodiments, the
rechargeable battery unit 126 is preferably a Lithium-Ion battery disposed within thecharger housing 120 and operatively connected with thepower input port 122 for recharging thebattery 126 when thecharger unit 110 is connected to an external power source via thepower input 122. Therechargeable battery 126 is also operatively connected with each of thepower output ports 124—via aninternal switch 130, operable by the on/offbutton 129—for recharging electronic devices connected to thecharger unit 110 via thepower output ports 124 from therechargeable battery unit 126. - Other components of
FIG. 5 are similarly numbered, and similar to, components ofFIG. 12 as further described herein. - The
connector cables charger housing 120 and theoutput ports 124, or alternatively, as further discussed with reference toFIGS. 6-11 , cables may be provided with the charger unit that are removable and interchangeable with other cables so as to permit different connection interfaces to be used with the charger unit. - Referring still to
FIGS. 1-4 ,storage cavities charger housing 120 for receiving theconnector cables FIGS. 3A and 3B illustrate theconnecter cables charger housing 120 in a non-use condition. By comparison,FIG. 2 showsdistal heads 156 of theconnector cables storage cavities respective connection interfaces - Referring still to
FIG. 2 , theconnector cables distal head 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 FIGS. 6-9 , proximal heads of the connector cables may include an interface that complements respective output ports provided in the charger housing for attaching the connector cables to the charger. - The
connector cables charger housing 120 to connect to an electronic device during use of thecharger unit 110. Thestorage cavities channels 152 to receive anelongated cord portion 162 of each of thecables charger housing 120. Thedistal heads 156 of theconnector cables interface receptacle 164 of eachrespective storage cavity charger housing 120. In some embodiments, the shape of thehead 156 complements theinterface receptacle 164 to provide a sleek look to thecharger housing 120 when theconnector cables head 156 andcord portion 162 of eachcable storage cavity connector cables storage cavities - In other embodiments, especially those where the connector cables can be removed and replaced, the interface receptacle receiving the distal head of a connector cable is sufficiently designed so as to accommodate heads with varying connection interfaces, and thus sizes and dimensions. Preferably, the storage cavity still permits the head to be stored within the storage cavity in a manner that provides a sleek look to the charger housing when the connector cables are stored, and thus, where connector cables are interchangeable, the distal heads on each cable are preferably uniform in shape, size and dimension so that they can be snap-fitted into the interface receptacle in the charger housing regardless of the connection interface for the cable.
- Referring to
FIG. 4A , thecharger housing 120 further includes apower connection port 122 that can act as a power input for connecting thecharger unit 110 to an external power source to recharge the internal rechargeable battery unit. As shown, thepower connection 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 a coaxial plug interface. - In an alternate embodiment of the
charger unit 110, thecharger housing 120 can include one or more additional output ports comprising, for example, a USB port for receiving a separate connector cable to attach additional devices to thecharger unit 110. Indeed, a squid connector can be used to connect multiple devices to thecharger unit 110 even when both of theconnector cables connector cables rechargeable battery 126, and theother connector cable power connection port 122 shown inFIG. 4A ) provided on thecharger housing 110 can be used to charge multiple electronic devices simultaneously. In such a situation, the output port requires a separate cable to be connected between the charger unit 110 (via the output port) and the device(s) to be recharged. - In accordance with the present invention, the charger unit is readily portable as a result of the small size of the housing. Despite the small size of the unit, the power capacity is very high (e.g., 5500 mAH or 6000 mAH) so that the charger can accommodate multiple electronic devices at the same time.
- Alternate embodiments of the charger unit are illustrated in
FIGS. 6-11 and particularly includes removable and interchangeable connector cables 225 or 325. As shown inFIG. 6 , acharger unit 210 comprises acharger housing 220 having twoflexible connector cables respective storage cavities respective output ports charger unit 210 to connect respective electronic devices to thecharger unit 210 to be recharged from an internalrechargeable battery unit 226. As noted, it is optimal for on-the-go use of thecharger unit 210 to include connector cables that are stored with thecharger housing 220. The functionality of thecharger unit 210 is improved by permitting the connector cables to be removed and replaced by a different charging cable, especially where different connection interfaces are needed for different electronic devices a user may be carrying. - As further shown, the
charger unit 210 further includes a power indicator means 228 and an on-off button 229, each operatively connected to internal functional components and electrical circuitry similar to those shown inFIG. 5 , for operating thecharger unit 210. - As noted, the

The distal head 256 is joined to theproximal head 260 by aflexible body 262, which houses a flexible conductive element (i.e. a wire). In general, theproximal connection interface 264 is designated for connection with anoutput port 224 included in thecharger housing 220, and as illustrated inFIGS. 6-8 , comprises a standard USB interface adapted to be received in and engage a standard USB connection port. The distal connection interfaces 258 are designed for connection with electronic devices in need of recharging from thecharger unit 210. Preferably, each connector interface uses a different distal connection interface 258 so that thecharger unit 210 can be used with electronic devices having varying charging ports simply by interchanging connector cables as appropriate. For example, as illustrated inFIG. 6 , oneconnector cable 225 a provides amicro-USB connection interface 258 a, while theother connector cable 225 b provides an Apple® Lightning™ connection interface 258 b. Thecables FIGS. 6-11 , two connector cables could be stored with the charger housing for on-the-go use. More preferably, as noted above, thecables proximal heads 260, and proximal connection interfaces 264 while providing different distal connection interfaces 258 so as to permit a user to easily change the connection interface for use with varying electronic devices. - The
connector cables charger housing 220 to connect to an electronic device during use of thecharger unit 210, as shown inFIG. 11 . Thestorage cavities channels 252 to receive anintermediate portion 262 of each of thecables charger housing 220. Each of the storage cavities 250 also comprises aproximal portion 266 that adjoins thechannel 252 adjacent to thepower output port 224 for receiving theproximal head 260, as well as adistal portion 268 that adjoins thechannel 252 for receiving the distal head 256 of the connector cable. - The proximal heads 260 of the
connector cables USB connection interface 264 that is insertable into a respective one of theUSB output sockets 224 that are supplied in thecharger housing 220, adjacent thestorage cavities proximal heads 260 are positioned within their respectiveproximal portions 266 of thestorage cavities USB sockets 224. The distal heads 256 may be removed from thedistal portions 268 of theirrespective storage cavities proximal heads 260 remain in their respective storage cavities and the USB interfaces 264 remain connected to theoutput ports 224. When theproximal heads 260 are stored within the storage cavities 250, they preferably form a smooth continuity with an outer surface of thecharger housing 220 so as to provide a sleek look to thehousing 220 when the connector cable is stored. - Each of the distal heads 256 of the
connector cables distal portion 268 of therespective storage cavity charger housing 220. Preferably, each distal head 256 is snap-fitted into thedistal portion 268 of the storage cavity 250 so that it does not accidentally disengage or otherwise come loose from the storage cavity while also providing a sleek look to thecharger housing 220 when the connector cable is stored. The storage cavities 250 are preferably designed to accommodate distal connection interfaces of varying design, shape and size so that the connector cables can be easily interchanged without detracting from the aesthetics of thecharger housing 220 when the cables are stored within thehousing 220. - In other embodiments, such as that illustrated in
FIG. 10 , at least one of the connector cables 325 can include plural distal heads 356 and associated connection interfaces 358. In this regard, theconnector cable 325 a is split so that eachdistal head charger housing 320 and optimally both connection interfaces 358 a, 358 c can be connected to a respective electronic device in need of recharging. Thestorage cavity 350 a, and more particularly, the interface portion 368, can be designed to accommodate bothdistal heads charger housing 320. Thus, thesplit connector cable 325 a includes two connection interfaces 358 a, 358 c atdistal heads portions - As shown, one interface comprises a micro-USB interface and one interface comprises an Apple® Lightning™ interface. The distal heads 356 are stored adjacent to one another in a common interface portion of the storage cavity. Likewise, the intermediate portions 362 of the connector cable 325 are collectively stored in a common channel 352 along the side of the charger housing. In use, the entire distal head 356 may be removed and flexed away from the charger housing while the proximal head 360 remains connected to the output port. The
distal heads - As further shown in
FIG. 10 , at least athird connector cable 325 d can be provided which has aproximal end 360 d hardwired into thecharger housing 320 as well as adistal head 356 d, carrying aconnector 358 d (e.g., a 30-pin connector as shown) and stored within acavity 368 d indented into the outer surface of thecharger housing 320. Thebody 362 d of the third connector cable likewise is stored within aslot 352 d that is indented into thecharger housing 320. - As illustrated in
FIGS. 6-8 , an entire connector cable 225 may be removed from its storage cavity 250. As discussed above, this allows different connector cables with different connection interfaces to be used so that electronic devices having varying power connection ports can be recharged using a charger unit in accordance with the present invention. In embodiments of the present invention, the shape and design of the storage cavities can be uniform so that connector cables can be attached to and stored within thecharger 210 on either side of thecharger housing 220. In this regard, the size and shape of the proximal heads, distal heads and intermediate portions of each connector cable can be uniform, with only the design of the connection interfaces varying. Thus, one would not need to keep track of connector cables designated for specific storage cavities and could freely interchange connector cables without affecting the look and shape of thecharger unit 210. As noted above, the interface portions of the storage cavities designated for receiving the distal heads of connector cables can be designed to receive a variety of connection interfaces, which facilities the removal and replacement of connector cables as may be necessary. - Additionally, when one of the connector cables 225 has been completely removed from its storage cavity 250, one of the
output connection ports 224 then is exposed and may be used to connect an electronic device using a different connector cable. For example, a squid connector can be inserted into one of theoutput connection ports 224 to connect two or more devices to the charger via a single output port. - The
charger housing 220 also includes a power indicator means 228 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 226 in thecharger unit 210 is. For example, in an embodiment of the present invention illustrated inFIG. 11 , the power indicator means 228 comprises designators that light up to indicate the battery capacity remaining in the power charger. Specifically, an “E” indicates that the battery is close to empty (e.g., about 1% to about 33%), and lights up with a red LED light. The “½” symbol indicates that the battery is about half full (e.g., about 34% to about 66%), and lights u with a yellow LED light. Lastly, an “F indicates a full or close to full battery (e.g., about 67% to about 99%), and lights up with a green LED light. Alternatively, the power indicator means may comprise a series of lights—when thebattery 226 is at full capacity, all the lights will be lit up, and as the battery power decreases, the lights will correspondingly decrease by one as the power is used such that if there is no capacity left in the internal battery, none of the lights will be lit up. Alternatively, the power indicator means 228 can comprise a digital interface that provides a battery capacity level for the internalrechargeable battery unit 226, or another known means of providing battery level information. - In preferred embodiments of the present invention, the charger unit turns on when an electronic device needing charging is plugged into the charger unit. In alternate embodiments of the present invention, the charger unit may include “shake-to-activate” technology, such as disclosed in co-pending U.S. application Ser. No. 13/800,996, incorporated herein by reference, whereby the unit may be turned on by shaking the charger housing. In further alternate embodiments, the charger unit can include an on/off button or switch for activating and deactivating the unit, such as the on/off
button 129 shown inFIG. 1 or the on/offbutton 229 shown inFIG. 11 . - The charger housing 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.).
- Referring to
FIG. 12 , thecharger unit 210 comprises numerous internal components that are similar to, and similarly numbered as, the components described with reference toFIG. 5 . Except as further discussed herein, it can be assumed the internal components of thecharger unit 210 are substantially similar to those of thecharger unit 110 as shown inFIG. 5 . - The
charger unit 210 comprises a controller, including aprocessing unit 232, which is configured to execute instructions and to carry out operations associated with thecharger unit 210. For example, theprocessing unit 232 can keep track of the capacity level of thebattery unit 226, 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 232 communicates with thebattery unit 226 to determine how much capacity is remaining in thebattery 226. Upon determining the capacity level, theprocessing unit 232 communicates with the power indicator means 228 to provide the user with the appropriate signal for showing how much capacity is remaining in the internalrechargeable battery unit 226. 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 210. - The
processing unit 232 also includes a smart interface to determine the total current required for the specific devices connected to thecharger unit 210. For example, if two devices are connected to thecharger unit 210 via each of theoutput ports 224, theprocessing unit 232 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 234 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 the charger unit 10. Similarly, if four devices are connected to thecharger unit 210 via various means connected to the output ports, theprocessing unit 232 will likewise assess how much power is needed to fully and efficiently charge each of the devices. In this regard, theprocessing unit 232 operates in connection with the input/output (I/O) support circuitry to control interactions with devices connected to thecharger unit 210. The I/O support circuitry may be integrated with theprocessing unit 232 or may be a separate component. Generally, the I/O support circuitry operates by exchanging power (and possibly data) between thecharger unit 210 and electronic devices connected thereto via theoutput ports 224. - The
processing unit 232 also preferably implements a timer for automatically turning thecharger unit 210 off if there is no device attached to theunit 210 for a predetermined period of time. In this regard, the capacity of thebattery 226 can be preserved. Upon shut down of thecharger unit 210, the power indicator means 228 will indicate that thecharger 210 is being turned off—for example, the lights will provide a sequential blinking signal. - The
processing unit 232 further includes astorage unit 236 that provides a place to hold data or instructions for operation of thecharger unit 210 andrechargeable battery unit 226, or data exchanged between thecharger unit 210, a computer, and electronic devices connected to thecharger unit 210, or memory needed for further operations of thecharger unit 210. - Referring to
FIG. 9 , thecharger housing 220 preferably includes apower input port 222 for connecting thecharger unit 210 to an external power source to recharge the internal rechargeable battery unit. As shown, thepower input port 222 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. Additionally, or alternatively, an ACwall plug interface 223 can also be provided for recharging the internal battery unit directly from a wall socket. As illustrated inFIG. 9 , thewall plug interface 223 is provided on the back of thecharger housing 220 and is preferably pivotable between a retracted, storage position, as shown, and an extended, use position where the prongs of thewall plug interface 223 project out and away from thecharger housing 220 for engagement with a standard wall socket. In the retracted position, the prongs of thewall plug interface 223 are pivoted to a storage position within the volume of thecharger housing 220 so as not to interfere with use of thecharger unit 210 when the plug function is not needed. The storage cavity for thewall plug interface 223 is designed so that the prongs can be easily pivoted to the extended position to plug theentire charger 210 directly into a wall socket. Where a wall socket is not available, thecharger unit 210 could be recharged via the USBconnection input port 222, where included. - In an alternate embodiment of the
charger unit 210, thecharger housing 220 can include one or more additional output connection ports comprising, for example, a USB port for receiving a separate connector cable (e.g., a USB cable) to attach additional devices to thecharger unit 210. Indeed, a squid connector, such as described and shown in co-pending U.S. application Ser. No. 13/571,992, can be used to connect multiple devices to thecharger unit 210 even when both of theconnector cables connector cables other connector cable port 222 shown inFIG. 6 ) provided on thecharger housing 210 can be used to charge multiple electronic devices simultaneously. In such a situation, the output port requires a separate cable to be connected between the charger unit 210 (via the output port) and the device(s) to be recharged. - A charger unit designed in accordance with the present invention is adaptable to recharge an electronic device connected to the charger unit directly from the internal rechargeable battery unit or alternately from a power source to which the charger unit is connected. Thus, the charger unit 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 the internal battery unit. Indeed, in a preferred embodiment of the present invention, a charge provided from a standard power source can recharge the internal battery unit simultaneously with one or more electronic devices connected to the charger unit. Additionally, the portable charger unit can be disconnected from a standard power source, even when electronic devices are connected to the charger unit, and continue to recharge the electronic device from the internal battery unit without interfering with the recharging process. For example, the charge switches from the external power source to the internal battery unit as necessary.
- As referred to above, the connector cables are removable and interchangeable as desired. The connector cables are preferably flexible so that they can be bent away from the charger housing to connect to an electronic device during use of the charger unit. The flexibility also assists in removing the entire connector cable from its storage cavity when necessary.
- Referring to
FIGS. 6-9 , additional features can be provided to increase the functionality of the charger unit. For example, an LED lightbulb 270 can be included on the charger to provide some light to assist in using the charger or for simple use as a flashlight. - The foregoing description of embodiments of the present invention has been presented for the purpose of illustration and description. It is not intended to be exhaustive or to limit the invention to the form disclosed. Obvious modifications and variations are possible in light of the above disclosure. The embodiments described were chosen to best illustrate the principles of the invention and practical applications thereof to enable one of ordinary skill in the art to utilize the invention in various embodiments and with various modifications as suited to the particular use contemplated.
