On June 30, three days after the Civil Aviation Administration's "New Power Bank Regulations" took effect, reporters observed a significant influx of power banks, suspected to have been confiscated at airports, being listed for sale on second-hand trading platforms. Concurrently, "3C Certified" power banks have emerged as a trending topic on food delivery platforms, experiencing a sharp uptick in sales. The newly enforced regulations prohibit the carriage of power banks without a clear 3C logo on domestic flights, driving consumers towards compliant products.
