AI Technical Summary

⚠Technical Problem

During the charging process, power bank chargers generate heat due to resistance loss, which can lead to the risk of the device overheating or even catching fire. Existing technologies have not been able to effectively solve this problem.

⚗Method used

The design incorporates an exhaust fan, a baffle plate, and baffle strips. The exhaust fan draws in external air, and the baffle plate and baffle strips guide the airflow to remove the heat from the power bank. At the same time, the combination of springs, swing arms, and a clamp ensures that the phone is securely clamped, preventing heat conduction.

🎯Benefits of technology

It effectively reduces the temperature of the power bank, prevents the device from overheating, improves the safety and convenience of charging, and avoids the risk of fire caused by heat conduction.
