Core Viewpoint - The regulatory crackdown on substandard power banks, driven by safety concerns, is significantly impacting the industry and consumers alike, with a focus on ensuring product quality and accountability across the supply chain [1][2]. Group 1: Regulatory Actions - The regulatory environment surrounding power banks has intensified, with measures including bans on non-3C certified power banks in airports and notifications from the Civil Aviation Administration prohibiting their transport on domestic flights [1]. - The number of non-compliant power banks intercepted at airports has increased following the implementation of new regulations [1]. Group 2: Market Dynamics - Despite the crackdown, there is a thriving market for "intercepted" power banks on second-hand trading platforms, where sellers capitalize on the situation to clear out old inventory [1]. - E-commerce platforms are witnessing a rise in vendors offering counterfeit 3C certification services, complicating the enforcement of regulations and the identification of compliant products [1]. Group 3: Consumer Impact - Consumers are facing increased costs and risks due to the inability to carry non-3C certified power banks and the potential purchase of substandard products without knowledge of their authenticity [2]. - The burden of ensuring product quality has shifted to consumers, who are left to deal with the consequences of failures in the production, sales, and certification processes [2]. Group 4: Accountability and Responsibility - The root causes of the issues in the power bank industry stem from manufacturers using inferior materials and non-compliant production methods, alongside lax oversight from e-commerce platforms [2]. - The ultimate goal of the regulatory actions should be to ensure that manufacturers, sales platforms, and certification bodies are held accountable for their roles in maintaining product quality, rather than placing the burden on consumers [2].
