FIGS. 15 and 16 illustrate another embodiment of a portable charging device 300, which includes a housing 301, and a cap 305, under which is a male connector (not shown) similar to male connector 107. In the device 300, there is no lid, and instead earbuds 400-1 and 400-2 are inserted into cavities 323 on sides of the housing 301, and protrude slightly from the housing 301 when inserted as shown in FIG. 15. According to an embodiment, the device 300 has the same or similar internal components (e.g., battery and PCBA) as the device 100 and the same or similar functionality as the device 100 (e.g., recharging of connected devices and inserted earbuds and pass through technology) as described herein above. Similar reference numerals between the devices 100 and 300 refer to the same or similar components.

In an embodiment, the portable recharging devices 100 and 300 maintain portability features such that, in a non-limiting example, the portable recharging devices 100 and 300 are small enough to fit in one's pocket for storage.

Although one male connector 107 and one female connector 113 are shown, the embodiments are not necessarily limited thereto. The devices 100 and 300 may include more than one male and/or female connectors for different types of connections. For example, the devices 100 can include male and female connectors for both Android? and Apple? portable devices.
