On June 26, the Civil Aviation Administration issued a directive stating that, effective June 28, passengers are prohibited from carrying power banks aboard domestic flights if they lack a 3C certification mark, have unclear 3C marks, or have been recalled. This measure is intended to bolster aviation safety and mitigate potential hazards such as power bank-related fires and smoke. Airports have acknowledged the directive and will rigorously enforce this regulation to ensure that all power banks carried by passengers adhere to safety standards.
