Effective June 28, the Civil Aviation Administration of China has enforced new regulations prohibiting passengers from carrying power banks lacking a 3C mark, displaying unclear 3C marks, or being subject to recall on domestic flights. On the inaugural day of these regulations, numerous netizens posted photos on social media showcasing the power banks confiscated during security checks, with the security checkpoints seemingly overflowing with these devices. Furthermore, observant netizens have uncovered a plethora of low-priced power banks labeled as "airport confiscated" or "security detained" on second-hand trading platforms.
