[0021] With the development of social media and high-definition technology, more and more electronic products are needed for business trips, travel, business activities, live streaming, and other fields, thus increasing the demand for power banks.
[0022] The power bank in the related technology, such as the one in the announcement number CN221842341U named a detachable charger and power bank structure, includes a power bank and a charger. The power bank and the charger are connected by a connecting part. The charger and the power bank are detachable. There is a second Type-C output cable on one side of the top of the power bank. There is a cavity on the side of the power bank away from the second Type-C output cable. From top to bottom, the side of the power bank near the second Type-C output cable has a fixing slot, a digital display switch, an LED digital display screen, a USB output and a Type-C input / output. The bottom of the socket has a foldable plug. There is a Type-C output on one side of the socket.
[0023] The aforementioned power banks suffer from several drawbacks: limited charger cable types, low storage efficiency, some cables are exposed, and the cables are internally connected to the power bank, leading to high repair costs after damage. Furthermore, carrying multiple data cables, chargers, and power banks while traveling takes up considerable space. Therefore, we propose a multi-functional power bank to address these issues.
