     DETAILED DESCRIPTION 
     The disclosure involves a device  100 , as shown in  FIG. 1 , configured for wireless charging. The device  100  may be, for example, a writing instrument such as, for example, a pen, mechanical pencil, stylus, marker, and combination thereof, as depicted in  FIG. 1 . While a writing instrument is detailed herein, the device  100  may be any portable device such as, for example, a correction tape, a shaver, a lighter, etc. In other words, the exemplary embodiments herein may not be limited to implementation in writing instruments, but may also be implemented with other portable devices, machines, systems, components, or in any other similar context in which the contemplated embodiments may be applicable. 
     In general, the device  100  may include a first housing  110  and a second housing  150 , which may together form an elongated body  115  of the device  100 . In one embodiment, the first housing  110  and the second housing  150  may initially be separate components, and may be joined together to form a uniform, continuous elongated body  115  by snap-fit, twist-screw connection, or any other similar connection that is now known or later developed in the art. In some embodiments, the elongated body  115  may be a unitary or single component. The elongated body  115  may also include a clip  112 , enabling the user to attach the device  100  to an object. The clip  112  may be formed as a part of the first housing  110  as shown in  FIG. 1  but may also be formed at any suitable location on the outer sidewall of the elongated body  115 . In general, the shape of the elongated body  115  may be cylindrical. However, the elongated body  115  may be of any suitable shape capable of accommodating the various embodiments disclosed herein. 
     The device  100  may be configured to wirelessly charge other devices, such as, for example, portable electronic devices, in close proximity. Such wireless charging device  100  may not include any mechanical link subject to breakage, such as connectors, cables, or other parts necessary for a physical connection. For example, the use of charging cables and electrical connectors, which might break or wear out easily, would not be required in wireless charging embodiments. The wireless charging device  100  may also avoid exerting stress and/or causing burnouts on the charging port of a receiving electronic device, as power transfer would occur without any physical connection. As alluded to above, wireless charging also removes the need to use electrical connectors, which can create electrical spikes or shocks that might damage the device or hurt the user. Therefore, the wireless charging device  100  may provide an overall safer way to transfer power to electronic devices. Furthermore, the wireless charging device  100  may eliminate the need to have different cables and electrical connectors for different types of electronic devices, providing a more convenient charging experience to users. 
     In one embodiment, the device  100  may be configured to wirelessly charge other portable electronic devices within a radius of approximately 2-3 feet. However, the radius may extend farther than 2-3 feet such as, for example, up to approximately 30 feet, or more. The wireless charging feature may utilize a power transmitter that emits a low wattage (W) charge. The power transmitter may be installed inside the elongated body  115  of the device  100 . To that end, the elongated body  115  (e.g., the first housing  110  and the second housing  150 ) may have a horizontal diameter and/or a vertical height that are large enough to host the power transmitter or components thereof. The components of the power transmitter may comprise a printed circuit board (PCB)  130 , an induction coil, and a battery, which will be described below in greater detail. 
     To activate or deactivate wireless charging, a switch  135  may be added on the outer surface of the elongated body  115 . The switch  135  may be an on/off switch that is labeled accordingly, and may be used to activate or deactivate the wireless charging feature of the device  100 . In one embodiment, the switch  135  may be positioned on the outer sidewall of the first housing  110  such that the likelihood of inadvertently pressing the switch  135  may be minimized. For example, the switch  135  may be positioned a certain distance below the top of the first housing  110 , and a certain distance above the second housing  150 , such that the switch  135  might not be inadvertently pressed when the user is utilizing the device  100 , such as, for example, during a writing activity. More specifically, the switch  135  may be positioned a certain distance below a series of actuation mechanisms  120 A,  120 B located near the top of the first housing  110 , and a certain distance above the top of the second housing  150 . However, the switch  135  may be positioned at any suitable location on the outer sidewall of the elongated body  115 , depending on the use and corresponding characteristics of the device  100 . 
     In one embodiment, the device  100  may be configured to produce multiple colors. Hence, the actuation mechanisms  120 A,  120 B may be, for example, buttons disposed on the outer sidewall of the elongated body  115 . The actuation mechanisms may allow the user to select and use from multiple colors during a writing activity. While only the actuation mechanisms  120 A and  120 B are visible in  FIG. 1 , there might be additional actuation mechanisms on the other side of the device  100 . In other words, the number of actuation mechanisms may be customizable. Each actuation mechanism  120 A and  120 B may be colored and configured to connect to a writing instrument, such as, for example, an ink cartridge or lead pencil that is disposed inside the elongated body  115  and that has a color which corresponds to the color of the actuation mechanism  120 A and  120 B (The ink cartridge and lead pencil are not shown in  FIG. 1  but are detailed more herein below). An end of the writing instrument may be a felt tip, ball point tip, lead tip or any other tip well known for writing, drawing, etc. A user pushing down on an actuation mechanism may facilitate partially ejecting, extending, or deploying the end of the corresponding writing instrument to slide out of the second housing  150  such that the end of the writing instrument protrudes through an opening  152  formed at a distal end of the second housing  150 . Although the actuation mechanisms  120 A and  120 B are shown to be located near the top of the elongated body  115 , the actuation mechanisms  120 A and  120 B may be positioned at any other suitable locations on the outer sidewall of the elongated body  115 . In some embodiments, the device  100  may be configured to produce a single color. In such a case, the device  100  may comprise a single colored actuation mechanism disposed on the outer surface of the elongated body  115  and a corresponding writing instrument disposed inside the elongated body  115 . However, in some embodiments, the device  100  that is configured to produce a single color may also include multiple actuation mechanisms, all of one color or all of the same color, and that correspond with writing instruments, all of just one color or all of the same color. In yet another embodiment, the device  100  may be configured to produce a single color and may not comprise any actuation mechanism. Hence, the writing instrument in such a device  100  may be fixed, and the end of the writing instrument may be exposed permanently outside the opening  152  and is not capable of being extended or retracted into and out of the elongated body  115 . In yet another embodiment, device  100  may include exactly one actuation mechanism at a top-most portion of the first housing  110  for deploying the end of the writing instrument through the opening  152  and outside of the elongated body  115 . The actuation mechanisms, either multiple or single, may be used to facilitate movement of the end of the writing instrument between a deployed position outside of the elongated body  115  and a retracted position inside of the elongated body  115 . 
     The device  100  may include an indicator  140  positioned at any suitable location on the outer surface of the elongated body  115 . In one embodiment, the indicator  140  may be positioned at an end of the elongated body  115  opposite to the opening  152 . In other embodiments, the indicator  140  may be positioned at any suitable location on the outer sidewall of the elongated body  115 . The indicator  140  may signal to the user that the device  100  is in a wireless charging mode. The indicator  140  may also be configured to signal whether an internal battery acting as a power source for wireless charging is low and needs to be replaced or recharged. In order to signal various conditions associated with the wireless charging feature, the indicator  140  may be a light source such as, for example, a light-emitting diode (LED) light, or any other suitable light source that is now known or later developed. The light emitted by the indicator  140  may be color-coded, may be turned on continuously, and/or may flash at a predefined rate, in order to distinctively signal various conditions. For example, a first color may indicate that the device  100  is wirelessly charging another device; a second color, different from the first color, may indicate that the device  100  is being charged itself (by wired or wireless mechanisms); and a third color, different from the first and second colors, may indicate that the internal battery of the device  100  is low. 
     The device  100  may also include a PCB  130  disposed inside the elongated body  115 . The PCB  130  may include the circuitry required to enable the wireless charging feature (e.g., a wireless charging circuit), and to activate or deactivate the wireless charging feature based on the input received via the switch  135 . To that end, the PCB  130  in the device  100  may include a wireless charging circuit. However, the PCB  130  may include other circuitries configured to perform the functions of the device  100  described herein. Further, the PCB  130  may control the light emitted by the indicator  140  to signal various conditions associated with the wireless charging feature. In one embodiment, the PCB  130  may be a flexible PCB, and may be bendable to fit within the elongated body  115 . The PCB  130  may include certain components that are not bendable (i.e., solid components), but those components may be small enough to allow the overall PCB  130  to flex or bend to fit within the elongated body  115 . For example, as shown in  FIG. 1 , the PCB  130  may be bent or rolled along an inner wall of the elongated body  115 , in order to not obstruct or interfere with other components of the device  100  associated with writing or drawing (e.g., ink cartridge(s), lead, etc.). The PCB  130  may thus be positioned between the inner wall of the elongated body  115  and the writing instrument(s). When rolled along the inner wall of the elongated body  115 , the PCB  130  may extend over a circumferential distance spanning approximately between 25% to 33% of an inner circumference of the elongated body  115 . However, it is contemplated in other embodiments, that the PCB  130  might span other suitable distances of the inner circumference of the elongated body  115 , such as, for example, more or less than 25%, more or less than 33%, more or less than 50%, or more or less than 75% of the inner circumference of the elongated body  115 . In the case of a device  100  comprising four writing instruments, the PCB  130  may extend over a circumferential distance spanning approximately one or two of the writing instruments. However, as noted above, the PCB  130  may cover more or less of the inner circumferential distance of the elongated body  115 . 
     Although not shown explicitly in  FIG. 1 , an induction coil and a battery may also be disposed inside the elongated body  115  and may be connected to the PCB  130 . The induction coil (e.g., coil antenna) may enable wireless inductive charging such as, for example, Qi charging, for wireless inductive charging-enabled devices. Wireless inductive charging uses a resonant inductive coupling between a sender device and a receiver device, to transfer energy from the sender device to the receiver device. The sender device may use an induction coil to create an electromagnetic field. The electromagnetic field created by the induction coil may induce a current flow in another induction coil in the receiver device, facilitating electronic power transfer between the sender device and the receiver device. In other words, an induction coil disposed in the device  100  may create an electromagnetic field, and an induction coil in the receiver device may take power from the electromagnetic field and convert it into electric current. The electronic current may then be used to charge a battery included in the receiver device. 
     In contrast to a wireless charging methodology which requires the receiver device be in a specific location and/or direction (i.e., orientation) relative to the sender device, the device  100  may allow for omnidirectional wireless charging by placing one or more induction coils in one or more locations inside the elongated body  115 . The placement of the induction coils may be optimized such that the receiver device may receive power from the device  100  in any direction and in a three-dimensional space all around the device  100 . The induction coils used for such omnidirectional wireless charging capability may comprise, for example, crossed dipole coils. The receiver device may also comprise induction coils that are similarly configured as those of the device  100 , in order to facilitate the omnidirectional wireless charging. In some embodiments however, the induction coil may be placed in a single (i.e., only one) location within the elongated body  115 , and may require the receiver device to be positioned in a certain location and/or direction relative to the device  100 . The induction coil(s) may be placed inside the elongated body  115  such that the coil(s) may not interfere with or obstruct the components associated with the disclosed writing/drawing functions. 
     As alluded to above, a battery may also be disposed inside the elongated body  115  and connected to the PCB  130 . In some embodiments, the battery can belong to an external device, such as for example, an external portable charging device disclosed in U.S. Pat. No. 10,374,449, the content of which may be incorporated herein by reference. The PCB  130  may receive AC power from the battery and provide a source current to the induction coil(s) for creating the electromagnetic field. In one embodiment, the battery may be a disposable battery such as, for example, a lithium or Ni—Cd battery. In other embodiments, the battery may be a rechargeable battery such as, for example, a lithium-ion battery, and the device  100  may have means to charge the battery in a wired or wireless manner. For instance, the device  100  may include a port that can be used for charging the rechargeable battery, such as a universal serial bus (USB) port, a micro USB port, a lightning port, an AC adapter port, or any other port that is now known or later developed for charging a device or a battery therein. An appropriately-sized battery may be selected to fit inside the elongated body  115  without significantly impacting the portability and/or usability of the device  100 . The battery may be a standard cylindrical battery with a charging capacity of approximately 300 mAh (milliampere hour), 500 mAh, or any other suitable value, and may be approximately 8 mm (millimeter) in diameter and 57 mm in height, although other suitable dimensions are also contemplated. In some embodiments, the battery may be embedded in the PCB  130 . In some embodiments where the PCB  130  is flexible, the battery may be spaced apart from the PCB  130  and may be coupled to the PCB  130  by, for example, a lead or other suitable structure that electrically couples the battery and the PCB  130 . 
     In another embodiment, as shown in  FIG. 3A , a battery  360 A that is cylindrical-shaped with a hollow center may be embedded in or may form a part of the first housing  110  or the second housing  150 . In yet another embodiment, as shown in  FIG. 3B , a battery  360 B that is arc-shaped may be embedded in or may form a part of the first housing  110  or the second housing  150 . The battery  360 B may thus extend only partially around a circumference of the first housing  110  or the second housing  150 . Instead of being embedded in or being formed a part of the housing  110  or  150 , the battery  360 A or  360 B may be formed on the inner wall or outer sidewall of the elongated body  115 . In one embodiment, the battery  360 A or  360 B may have a charging capacity that is less than or equal to approximately 200 mAh. The charging capacity of a battery is usually proportional to the size and/or weight of the battery. For instance, batteries with a higher charging capacity are usually bigger and/or heavier. Thus, the dimensions of the battery (e.g., diameter, thickness, circumference, length, etc.) may be adjusted in order to increase or decrease the charging capacity, based on the charging needs, dimensions and characteristics of other components of the device  100 , and/or such that the writing/drawing experience is not substantially degraded by negatively impacting the weight, center of gravity, and other relevant characteristics of the device  100 . 
     It should be noted that, although an induction coil is presented as an exemplary component configured to transfer power wirelessly from one device to another (i.e., a power transmitter), other types of components may also be used to transfer power wirelessly. For example, electronic components in plastic materials such as, for example, plastronics components, may be used to integrate one or more antennas with the device  100 . In such a case, the one or more antennas may be installed inside the elongated body  115 , or may be formed on the outer sidewall of the elongated body  115 . As another example, one or more ceramic antennas may be integrated with the device  100  to transfer power wirelessly. Similarly, the one or more ceramic antennas may be installed inside the elongated body  115 , or may be formed on the outer sidewall of the elongated body  115 . Therefore, it will be apparent to one of ordinary skill in the art that a component configured to transfer power wirelessly from the device  100  to a receiver device may not be limited to the exemplary components discussed explicitly herein, but may be any suitable device that is now known or later developed for transferring power wirelessly. 
       FIG. 2A  shows an exemplary context in which the device contemplated in the present disclosure may be used. In  FIG. 2A , a user may utilize the device  100  for writing/drawing. However, the device  100  or sender device  100  may be positioned within the designated accessible wireless range of 2-30 feet of a receiver device  200  such as a mobile phone that may be low on power, and may provide power wirelessly to charge the receiver device  200 . The user may activate the wireless charging feature of the device  100  by pressing the switch  135  and may either resume writing/drawing or rest the device  100  on a desktop or any other surface. As long as the device  100  and the receiver device  200  are within the wireless charging range, the receiver device  200  may start charging by using the power received from the device  100 . While a mobile phone is discussed, it is feasible that the device  100  may also be used with other portable electronic devices such as, for example, a laptop computer, electronic reading tablets, earphones, speakers, microphones, and other audio devices. 
       FIG. 2B  shows another exemplary context in which the device  100  of the present disclosure may be used. In  FIG. 2B , a user may be in possession of the device  100  but may not be actually using the device  100  for writing/drawing. For instance, the user may have the device  100  close to his/her body such as, for example, in his/her shirt pocket, and may have the receiver device  200  in his/her pants pocket or hand, or vice versa. If the device  100  and the receiver device  200  are within the wireless charging range, the receiver device  200  may start charging by using the power received from the device  100  once the wireless charging feature of the device  100  is turned on via the switch  135 . It will be apparent that the uses of the device  100  as illustrated in  FIGS. 2A-2B  are merely exemplary, and that the device  100  and its wireless charging capability may be used in a variety of contexts. 
       FIG. 4A  shows a side view of an embodiment of a device  400  configured for wired charging. The device  400  may be a portable device. The device  400  may also be used for writing or drawing.  FIG. 4B  shows a partially exploded view of the portable device depicted in  FIG. 4A .  FIG. 4C  is a top or end view of the portable device depicted in  FIGS. 4A and 4B . In the description below, reference will be made to  FIGS. 4A-4C . 
     In lieu of the wireless charging capability illustrated in reference to  FIG. 1 , the device  400  may also be capable of charging other electronic devices, but in a “wired” manner. Such wired charging device  400  may have a relatively high charging efficiency and may be compatible with a relatively high number of electronic devices. In general, and similarly to the device  100 , the device  400  may include a first housing  410  and a second housing  450 , which may together form an elongated body  415  of the device  400 . In one embodiment, the first housing  410  and the second housing  450  may initially be separate components, and may be joined together to form a uniform, continuous elongated body  415  by snap-fit, twist-screw connection, or any other similar connection that is now known or later developed in the art. In some embodiments, the elongated body  415  may be a unitary or single component. The elongated body  415  may also include a clip  412 , enabling the user to attach the device  400  to an object. The clip  412  may be formed as a part of the first housing  410 , as shown in  FIG. 4A , but may also be formed at any suitable location on the outer sidewall of the elongated body  415 . In general, the shape of the elongated body  415  may be cylindrical. However, the elongated body  415  may be of any suitable shape capable of accommodating the various embodiments disclosed herein. 
     In one embodiment, the device  400  may be configured to accommodate a wired charging function, as well as may be configured to produce multiple colors. Hence, the device  400  may include multiple actuation mechanisms  420 A,  420 B,  420 C,  420 D. Actuation mechanism  420 A may be configured solely to the wired function of the device  400 , while actuation mechanisms  420 B,  420 C,  420 D may be configured to facilitate the use of multiple colors during a writing or drawing activity. The actuation mechanisms  420 A,  420 B,  420 C,  420 D may be such as, for example, buttons disposed on the outer sidewall of the elongated body  415 . 
     As noted above with the previous embodiment of  FIG. 1 , the actuation mechanisms  420 B,  420 C,  420 D allow the user to select from and use multiple colors during the writing activity. Each actuation mechanism  420 B,  420 C,  420 D may be connected to a corresponding writing instrument  425 B,  425 C,  425 D such as, for example, an ink cartridge or lead pencil that is disposed inside the elongated body  415 . The actuation mechanisms  420 B,  420 C,  420 D may be a color that corresponds with a color of ink contained in the writing instruments  425 B,  425 C,  425 D. An end of the writing instruments  425 B,  425 C,  425 D may be a felt tip, ball point tip, lead tip or any other tip well known for writing, drawing, etc. A user pushing down on the actuation mechanisms  420 B,  420 C,  420 D may facilitate partially ejecting, extending or deploying the end of the corresponding writing instruments  425 B,  425 C,  425 D to slide out of the second housing  450 . The ejection, extension or deployment of the end of the writing instruments  425 B,  425 C,  425 D may cause the end of the writing instruments  425 B,  425 C,  425 D to protrude through an opening  452  formed at a distal end of the second housing  450 . Although the actuation mechanisms  420 B,  420 C, and  420 D are shown to be located near the top of the elongated body  415 , the actuation mechanisms  420 B,  420 C, and  420 D may also be positioned at any other suitable locations on the outer sidewall of the elongated body  415 . In some embodiments, the device  400  may be configured to produce a single color. In such a case, the device  400  may include only one actuation mechanism disposed on the outer surface of the elongated body  415  that is specific to a corresponding writing instrument disposed inside the elongated body  415 . However, in some embodiments, the device  400  that is configured to produce a single color may also include multiple actuation mechanisms, all of one color or all of the same color, and that correspond with writing instruments, all of just one color or all of the same color. In yet another embodiment, the device  400  may be configured to produce a single color and may not include any actuation mechanism. Hence, the writing instrument in such a device  400  may be fixed, and the end of the writing instrument may be exposed permanently outside the opening  452  and is not capable of being extended or retracted into and out of the elongated body  415 . In yet another embodiment, the device  400  may include exactly one actuation mechanism at a top-most portion of the first housing  410  for facilitating deployment of the writing instrument between a deployed position outside of the elongated body  415  and a retracted position inside of the elongated body  415 . 
     Differently from  FIG. 1 , the device  400  of  FIGS. 4A-4C  may include a wired charging feature. To enable the wired charging feature, the actuation mechanism  420 A of the device  400  may be specific to a charging cable  425  A disposed inside the elongated body  415 . When the user pushes down on the actuation mechanism  420 A, the charging cable  425 A may slide out of an opening  454  located in the outer sidewall of the elongated body  415 . It is also perceivable that an embodiment may involve the charging cable  425 A being configured to project out of the opening  452  formed at the distal end of the first housing  450 . In this instance, the opening  452  may be configured with dual ports, one to accommodate at least one of the writing instruments  425 B,  425 C,  425 D at a time and the other to accommodate deployment of the charging cable  425 A. Here, individual cylinders or tubes (not shown) may be connected to the actuation mechanisms and extend to the corresponding opening to assist with guiding and to ensure an appropriate deployment of either the writing instruments  425 B,  425 C,  425 D or the charging cable  425 A. In other embodiments, the first housing  410  and the second housing  450  may simply be separated from one another exposing the charging cable  425 A, as shown in  FIG. 4C . In this embodiment; however, use of the writing instruments  425 B,  425 C,  425 D while charging the receiver device  200  may not be permitted. The charging cable  425 A may include a power connector  427 . The power connector  427  may be inserted into an appropriate port of the receiver device  200  such as, for example, a mobile phone, laptop computer, electronic reading tablets, earphones, speakers, microphones and other audio devices to enable power transfer from the device  400  to the receiver device  200 . For example, the power connector  427  may be a USB connector, a micro USB connector, a lightning connector, or any other connector that is now known or later developed for charging a device or a battery therein. 
     The charging cable  425 A may be connected to a PCB  130  similar to the one described in reference to  FIG. 1 . The PCB  130  may in turn be connected to a power source such as a battery similar to the one described in reference to  FIGS. 1 and 3A-3B . The PCB  130  in the device  400  may include a circuitry required to enable the wired charging feature, and to activate or deactivate the wired charging feature. To that end, the PCB  130  in the device  400  may include a battery management system (BMS) circuit. However, the PCB  130  may include other circuitries configured to perform the functions of the device  400  described herein. In one embodiment, the power transfer may be initiated upon the power connector  427  being inserted into the port of the receiver device  200 . In some embodiments, the power transfer may not be initiated immediately upon the power connector  427  being connected to the receiver device  200 . For example, a switch  135  similar to the one described in reference to  FIG. 1  may be formed on the elongated body  415 , and the power transfer may be initiated upon the switch  135  being pressed by a user. An indicator  140  similar to the one described in reference to  FIG. 1  may also be included on the device  400 , to signal the status of wired charging. 
     Therefore, although not explicitly shown in  FIGS. 4A-4B , the device  400  may also comprise an indicator, a switch, and a battery, all of which are operatively connected to a PCB. The indicator, switch, battery, and PCB of the device  400  may operate and be configured in a similar manner to that described in reference to  FIGS. 1 and 3A-3B , in order to control wired charging and signal the status of the wired charging. Thus, for the sake of brevity, the operations and configurations of these components will not be repeated in this section. Since the device  400  is configured for wired charging, the induction coil discussed in reference to  FIG. 1  may not be needed. However, in some embodiments, the device  400  may comprise induction coil(s) to additionally provide the wireless charging capability as described above. In such a case, the device  400  may be capable of both wired and wireless charging. 
       FIG. 5A  shows a schematic side view of an embodiment of a writing device  500  configured for wireless charging. In particular,  FIG. 5A  illustrates an exemplary configuration (e.g., placement) of a writing instrument  525 , a battery  560 , a PCB  530 , and a power transmitter  570  implemented in the device  500 . Other components of the device  500  such as, for example, a housing or a body, a cap, etc. are not explicitly shown in  FIG. 5A  for the purpose of clearly illustrating the configuration. Notably, the device  500  may use an appropriately-sized writing instrument  525  (e.g., ink cartridge) that allows for an adequate space for a battery  560  and a PCB  530 . It will be apparent to one of ordinary skill in the art that certain components and configurations thereof of the device  100  explained above may also be applicable to the device  500 . For the sake of brevity, detailed description of these components and configurations thereof will not be repeated in the following sections. 
     The device  500  may be configured to charge other electronic devices wirelessly, such as by using a power transmitter  570  installed on the device  500  as shown in  FIG. 5B , In one embodiment, the power transmitter  570  may be installed between the inner wall of a housing (not shown) of the device  500  and the space occupied by the PCB  530 , battery  560 , and writing instrument  525 . In other embodiments, the power transmitter  570  may be embedded in the housing of the device  500 , or may be installed on the outer sidewall of the housing of the device  500 . In such a case, the housing of the device  500  may just enclose the PCB  530 , battery  560 , and writing instrument  525 , and not the power transmitter  570 . 
     The writing instrument  525  of the device  500  may be an advanced ink system such as, for example, a cartridge-less reservoir. Such writing instrument  525  may form a reservoir as part of the housing of the device  500 , and may not be a separate, detachable ink cartridge as those depicted in  FIG. 4B  (herein referred to as a “standard reservoir”). For example, the housing of the device  500  itself may store ink, with the inner wall of the housing being in direct contact with the ink. Because such writing instrument  525  usually has a diameter larger than that of a standard reservoir, the writing instrument  525  may be able to store at least an equal amount of ink as that of the standard reservoir while having a shorter length. For example, when compared to a standard reservoir of equal length, the ink capacity (i.e., a storable amount of ink) of the writing instrument  525  may be approximately three times the ink capacity of the standard reservoir. Therefore, as depicted in  FIG. 5A , the writing instrument  525  may be substantially shortened to make space available for other components needed for wireless charging (e.g., a battery  560 , a PCB  530 , and a power transmitter  570 ), without substantially impacting the mileage or usable life of the writing/drawing function of the device  500 . In one embodiment, the use of the writing instrument  525  may free up the space inside the housing to approximately two thirds (⅔) of the length of the device  500 , in which the components associated with wireless charging may be installed. However, the writing instrument  525  can be adjusted to any length, depending on the dimensions and characteristics of other components including those associated with wireless charging. In some embodiments, to preserve space inside the housing, the power transmitter  570  can be disposed in the clip of the writing instrument. 
     As depicted in  FIG. 5A , a battery  560  may be installed adjacent the writing instrument  525 . That is, when the device  500  is in an upright (i.e., vertical) position with the end of the writing instrument  525  pointing downward, the battery  560  may be installed above the writing instrument  525 . The battery  560  may be cylindrical-shaped. As explained above, the battery  560  may be a disposable battery such as, for example, a lithium battery, or a rechargeable battery such as, for example, a lithium-ion battery. In one embodiment, the battery  560  may have a charging capacity that is less than or equal to approximately 500 mAh. However, the charging capacity of the battery  560  may be adjusted to a lower or higher level, depending on the charging needs and space available in the device  500 , and/or such that the writing/drawing experience is not substantially degraded by negatively impacting the weight, center of gravity, and/or other relevant characteristics of the device  500 . In an alternate embodiment, the battery  360 A or  360 B in  FIGS. 3A-3B  may be installed in the device  500  in a manner similar to that explained in reference to  FIGS. 3A-3B . 
     A PCB  530  may be installed adjacent the battery  560 , towards the other end of the device  500 . That is, when the device  500  is in an upright (i.e., vertical) position with the end of the writing instrument  525  pointing downward, the PCB  530  may be installed above the battery  560 . As explained above in reference to  FIG. 1 , the PCB  530  may be bendable or flexible, and may include a circuitry operatively coupled to the battery  560  and the power transmitter  570  to enable wireless charging. 
     Continuing with reference to  FIG. 5A , a power transmitter  570  may be installed within the housing of the device  500 , between the inner wall of the housing and the space occupied by the PCB  530 , battery  560 , and writing instrument  525 . As explained above, the power transmitter  570  may also be installed outside the housing of the device  500 . In one embodiment, the power transmitter  570  may be installed substantially toward the top end of the device  500  as shown in  FIG. 5A . However, the placement of the power transmitter  570  is not limited to this configuration and the power transmitter  570  may be placed at any suitable location along the periphery of the space occupied by the PCB  530 , battery  560 , and writing instrument  525 . As explained above, the power transmitter  570  may include induction coil(s), plastronics antenna(s), ceramic antenna(s), or any suitable power transmitter that is now known or later developed to be capable of transferring power wirelessly. 
       FIG. 5B  shows a schematic side view of an embodiment of a writing device  550  configured for wired charging. In particular,  FIG. 5B  illustrates an exemplary configuration (e.g., placement) of a writing instrument  525 , a battery  560 , and a PCB and power connector (together referenced as  537 ) implemented in the device  550 . Other components of the device  550  such as, for example, a housing or a body, a cap, etc., are not explicitly shown in  FIG. 5B  for the purpose of clearly illustrating the configuration. Notably, the device  550  may use an appropriately-sized writing instrument  525  (e.g., ink cartridge) that allows for an adequate space for a battery  560  and a PCB and power connector  537 . It will be apparent to one of ordinary skill in the art that certain components and configurations thereof of the device  400  explained above may also be applicable to the device  550 . For the sake of brevity, detailed description of these components and configurations thereof will not be repeated in the following sections. 
     The device  550  may be configured to charge other electronic devices in a “wired” or “wireless” manner, such as by using a power connector installed at a distal end of the device  550 . As shown in  FIG. 5B , the power connector may be installed at a distal end that is opposite from the end of the writing instrument  525 , which may be a felt tip, ball point tip, or any other tip well known for writing, drawing, etc. The writing instrument  525  of the device  550  may be an advanced ink system such as, for example, a cartridge-less reservoir, same as the one described in reference to the device  500 . As depicted in  FIG. 5B , the writing instrument  525  may be substantially shortened to make space available for other components needed for wired charging (e.g., a battery  560  and a PCB and power connector  537 ), without substantially impacting the mileage or usable life of the writing/drawing function of the device  550 . In one embodiment, the use of the writing instrument  525  may free up the space inside the housing to approximately two thirds (⅔) of the length of the device  550 , in which the components associated with wired charging may be installed. However, the writing instrument  525  can be adjusted to any length, depending on the dimensions and characteristics of other components including those associated with wired charging. 
     As depicted in  FIG. 5B , a battery  560  may be installed adjacent the writing instrument  525 . That is, when the device  550  is in an upright (i.e., vertical) position with the end of the writing instrument  525  pointing downward, the battery  560  may be installed above the writing instrument  525 . The battery  560  in  FIG. 5B  may be configured in the same manner as, or in a manner similar to that described in reference to the battery  560  in  FIG. 5A . 
     Continuing with reference to  FIG. 5A , a PCB and power connector  537  may be installed adjacent the battery  560 , towards the other end of the device  550 . That is, when the device  550  is in an upright (i.e., vertical) position with the end of the writing instrument  525  pointing downward, the PCB and power connector  537  may be installed above the battery  560 . More specifically, the PCB may be installed between the battery  560  and the power connector, and may include a circuitry operatively connected to the battery  560  and the power connector to enable wired charging. As explained above in reference to  FIGS. 4A-4C , the PCB in the device  550  may be bendable or flexible. The power connector in the device  550  may include any of the connectors described above with respect to the power connector  427 . While the PCB, battery  560 , and writing instrument  525  may be disposed within the housing of the device  550 , all or a portion of the power connector may be exposed via an opening at a distal end of the housing. The exposed power connector may be inserted into a corresponding port of a receiver device  200  for charging, as explained above. In some embodiments, the exposed power connector may be concealed by attaching a removable cap over the opening at the distal end of the housing. The removal cap may be attached to the housing by snap-fit, twist-screw connection, or any other similar connection that is now known or later developed in the art.
