Core Viewpoint - The new regulations for carrying power banks on flights have led to a significant market reshuffle, with many non-compliant power banks being discarded or sold at low prices on second-hand platforms [1][8][10]. Group 1: Handling of Non-Compliant Power Banks - Airports have implemented three main methods for handling intercepted power banks: self-disposal by passengers, mailing via express services, or temporary storage for up to seven days [2][6][7]. - The cost for mailing power banks varies, with prices around 15-19 yuan depending on the region [6][7]. Group 2: Second-Hand Market Dynamics - A surge in second-hand power banks has been observed on platforms like Xianyu, with prices ranging from tens to over thirty yuan, often labeled as "airport intercepted" [8][10]. - Some sellers claim to offer tested and functional power banks, despite lacking necessary certifications, raising concerns about safety and legality [8][10]. Group 3: Regulatory and Safety Concerns - Legal experts highlight that unauthorized handling of discarded power banks can lead to significant penalties, including fines ranging from 50,000 to 500,000 yuan [10][11]. - The current regulatory framework does not explicitly cover power banks, creating loopholes that some businesses exploit [11][12]. Group 4: Recommendations for Improvement - Experts suggest establishing a closed-loop system for power bank disposal and enhancing the traceability of intercepted products [13]. - There is a call for stricter regulations on second-hand platforms, including seller verification and the promotion of certified products [13].
