爆炸的充电宝：从召回到禁止登机，谁在透支安全底线？

Core Viewpoint - The recent ban on boarding power banks without 3C certification has raised significant concerns regarding the safety of these devices, particularly following multiple recalls due to safety hazards [1][2][9]. Group 1: Regulatory Changes - Starting June 28, travelers are prohibited from carrying power banks that lack 3C certification, have unclear certification, or belong to recalled models on domestic flights [2][6]. - Some airports, including Shenyang Taoxian International Airport, have already begun enforcing these regulations ahead of the official date [6]. Group 2: Safety Incidents and Recalls - The issue escalated in mid-June when several universities in Beijing banned the use of Romoss power banks due to safety concerns, citing a higher risk of explosion compared to other brands [9]. - Romoss announced a recall of over 490,000 units, while Anker also recalled over 710,000 units due to similar safety risks associated with overheating lithium-ion batteries [9][15]. Group 3: Certification and Compliance - A significant number of power bank brands, including Romoss, Anker, and others, have had their 3C certifications suspended or revoked, affecting hundreds of models [8][31]. - The 3C certification, which stands for China Compulsory Certification, is a mandatory safety standard for various products, including power banks, and will become a strict requirement for all power banks by August 2024 [27][28]. Group 4: Industry Implications - The recalls and safety concerns have highlighted systemic risks within the supply chain, particularly regarding battery suppliers like Amperes, which has also faced certification issues [15][18]. - The competitive pressure in the power bank market has led to cost-cutting measures that may compromise safety, with reports suggesting that some manufacturers may use substandard materials to reduce costs [18][26].
