AI Technical Summary

Technical Problem

Traditional power banks have a relatively simple retractable cable structure, using only a single metal spring to extend and retract the charging cable. After prolonged use, the cable is prone to deformation, which affects the extension and retraction effect. The cable is also limited in function and provides a poor user experience.

Method used

It uses four springs instead of a single metal spring, combined with the design of a lifting rod and a moving rod, and achieves elastic extension and retraction of the charging cable through the handle rope. It is also equipped with a guide rod and a locking component to ensure stability and locking function.

Benefits of technology

It extends the lifespan of the charging cable, ensures the stability of the extension effect, enriches the functions of the power bank, improves the user experience, and is easy to carry.
