[0071] Understandably, the arrangement of data cable 4 and data cable slot 242 allows users to directly charge external devices via data cable 4 without carrying an external data cable, thus improving the practicality and ease of use of the power bank 1.

[0072] Please see Figure 1 , Figure 5 and Figure 6 Furthermore, the data cable 4 includes a data plug 41, and each data cable slot 242 has at least one locking protrusion 243 on its inner wall; when the data cable 4 is housed in the data cable slot 242, the data plug 41 is locked and connected to the locking protrusion 243.

[0073] Specifically, in this embodiment, each inner wall of each data cable slot 242 has two locking protrusions 243, that is, each data cable slot 242 has four locking protrusions 243.

[0074] Understandably, the locking action between the data plug 41 and the locking protrusion 243 secures the data plug 41 within the data cable slot 242, greatly improving the stability of the data cable slot 242 in storing the data plug 41. This prevents the data cable 4 from slipping out during use and causing accidental damage, thus effectively protecting the data cable 4 and improving the practicality of the power bank 1.

[0075] More specifically, magnetic attracting elements with mutual magnetic attraction can be correspondingly provided in the housing of the data plug 41 and the data cable slot 242 to further prevent the data cable 4 from slipping out of the data cable slot 242.

[0076] Furthermore, each data cable slot 242 has a bevel 244 on the inner wall of the side opposite to the data plug 41.

[0077] Understandably, the bevel 244 provides an extra space within the data cable slot 242, making it easier for the user to insert their finger and remove the data plug 41, thereby removing the data cable 4, thus improving the usability of the data cable slot 242 and the data cable 4.

[0078] Furthermore, a pair of lanyard holes 245 are provided on the side 24; when the data cable 4 near the lanyard hole 245 is received in the data cable groove 242, part of the data cable 4 passes through the lanyard hole 245 and forms a loop-shaped lanyard portion 42 on the outside of the housing 2; when the data plug 41 is taken out from the data cable groove 242, the data cable 4 extends in the removal direction, and the length of the lanyard portion 42 is correspondingly shortened.

[0079] Understandably, the lanyard portion 42 formed on the outside of the housing 2 by the data cable 4 can serve as a lanyard or handle, making it convenient for users to hold the power bank 1 when carrying it, thus improving the portability of the power bank 1.

[0080] Understandably, the lanyard part 42 effectively utilizes the space outside the outer casing 2, greatly saving the length that the data cable slot 242 needs to be opened on the outer casing 2; and when the user needs to use the data cable 4 for wired charging, the data plug 41 is taken out and the data cable 4 is stretched, the length of the lanyard part 42 is shortened and then passes through the data cable slot 242 and is pulled out, thereby realizing the switching of the data cable 4 from the storage state to the use state, which greatly improves the practicality and ease of use of the data cable 4.
