[0024] Please see Figures 1-5This utility model provides a portable power bank, including a housing 1, a battery cell 6, and a charging cable 3. The battery cell 6 is placed inside the housing 1, and one end of the charging cable 3 extends into the housing 1 and connects to the battery cell 6. The housing 1 includes a front panel 11 and a rear panel 12 arranged opposite to each other. The other end of the charging cable 3 passes through a side 5 along the length of the housing 1 and extends. The rear panel 12 has a groove 34 along its length to accommodate the charging cable 3. The groove 34 passes through the side 5 of the housing 1 near the point where the charging cable 3 passes through and forms a side hole 4. The charging cable 3 can be detachably placed in the groove 34 after passing through the side hole 4. The charging cable 3 includes a wire segment 31 and a charging cable. The interface 32, the overall size of which is larger than the side hole 4, is used for charging. Here, the battery cell 6 is typically connected to a control board for the power bank's electronic control and for charging and discharging. The charging cable 3 is used to connect to external electronic components for charging. Traditionally, the charging cable 3 is only used for charging and has no other additional purpose. In this application, after the charging cable 3 is inserted through the side hole 4, the charging interface 32, being larger than the side hole 4, is secured to the side hole 4. This creates a ring-shaped hook 35 on the side 5, allowing the user to hang the power bank when storing it, preventing loss, or allowing the hand to pass through for easy daily carrying. When not in use, the charging cable 3 can be stored through the cable groove 34.

[0025] In other usage scenarios, the hook part 35 can be used as a hanging part, such as hanging on a backpack, keychain, or handbag, or carried by passing fingers through the hook part. The hook part 35 can usually withstand a weight of up to 10-15kg, ensuring safe use.

[0026] In one embodiment, the length of the portion of the charging cable 3 located outside the housing 1 is greater than the length of the cable groove 34. When the charging cable 3 is completely placed inside the cable groove 34, a first annular hook portion 35 is formed on the side of the charging cable 3 located away from the cable groove 34 at the side hole 4. Here, this state is the state when the charging cable 3 is stored. At this time, since the length of the portion of the charging cable 3 located outside the housing 1 is greater than the length of the cable groove 34, the first annular hook portion 35 formed can also provide a smaller hook portion, which is suitable for hooking keychains.

[0027] In one embodiment, when the charging cable 3 is placed outside the cable groove 34, the charging cable 3 forms a second annular hook portion on the side of the side hole 4 away from the cable groove 34. The inner area enclosed by the second annular hook portion is larger than the inner area enclosed by the first annular hook portion 35. When the charging interface 32 of the charging cable 3 is taken out from the cable groove 34, as the charging interface 32 is pushed towards the side hole 4, the second annular hook portion gradually increases, thereby providing a larger hook ring, which can adapt to more hooking scenarios, such as being suitable for hand-held applications.

[0028] In one embodiment, the front panel 11 includes a first wireless charging unit 113 and a second wireless charging unit 112. Both the first wireless charging unit 113 and the second wireless charging unit 112 have three coils of wireless charging cable built in, and the three coils of wireless charging cable are connected to the battery cell 6. The arrangement of the first wireless charging unit 113 and the second wireless charging unit 112 enables wireless charging of different wireless charging-enabled devices when placed in this position, thereby expanding the charging function of the power bank.

[0029] In one embodiment, the surface of the second wireless charging unit 112 has a recessed structure; the recessed structure can support charging of the smartwatch. Typically, the back of the smartwatch has an arc-shaped protruding sensor component, so the recessed design can make its back fit more closely, thereby achieving more stable wireless charging.

[0030] In another embodiment, the first wireless charging unit 113 does not have a charging function, but instead has a display screen for displaying battery information such as battery level.

[0031] In one embodiment, the front panel 11 is provided with anti-slip texture 111 around the first wireless charging unit 113 and the second wireless charging unit 112 to prevent the electronic device from slipping off the power bank while charging.

[0032] In one embodiment, the outer casing 1 has an arc-shaped side structure, and the side includes a power button 2. The power button 2 is connected to the battery cell 6 and is used to control whether the battery cell 6 is discharged.

[0033] In one embodiment, the side hole 4 of the cable tray 34 includes a limiting block 33, which is integrally formed by the rear panel or detachably connected to the rear panel; when detachably connected, it is convenient to completely remove the charging cable to facilitate cleaning of the cable tray 34 and the charging cable.

[0034] In another embodiment, the cable groove 34 is provided with micro-protruding particles to increase the fixing structure of the charging cable within the groove, enhance the friction with the charging cable, and prevent slippage. The cable groove 34 is ultrasonically sealed to achieve a waterproof seal. In another embodiment, the outer casing 1 may be made of waterproof plastic to achieve the waterproof function of the power bank, and a waterproof sealing structure 7 is provided between the front panel 11 and the rear panel 12 of the outer casing 1 to prevent water from penetrating into the interior and affecting its use.

[0035] The advantages of this utility model are: The design of the cable groove and side hole allows the charging cable to form a ring hook on the side of the side hole away from the cable groove. The size of the hook can be adjusted by adjusting the length of the charging cable passing through the side hole, making it easy to carry and preventing loss.

[0036] The above-disclosed embodiments are only a few specific examples of this utility model. However, this utility model is not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
