Both the flexible handle and the flexible connecting strap are easy to detach and replace.

[0039] When the power bank needs to be moved, the user holds the flexible handle strap through the rectangular through-hole and pulls it upwards. This overcomes the tension of the spring inside the adjustment unit. The user then pulls the limiting block via the flexible handle strap, the Y-shaped rigid connecting frame, and the flexible connecting strip, causing the limiting block to slide within the mounting groove. This releases the length, allowing the flexible handle strap to be pulled out of the recessed area for easy carrying. After releasing the flexible handle strap, the limiting block returns to its original position under the action of the spring. The flexible handle strap is then pulled back by the flexible connecting strip and the rigid connecting frame, and completely retracted into the recessed area on the top of the power bank housing, achieving a flat top and facilitating placement of the power bank.
