China Bans Power Banks Without 3C Certification on Domestic Flights

China has officially banned the use of power banks without the China Compulsory Certification (3C) mark on all domestic flights, effective June 28, 2025. The move comes amid mounting safety concerns over lithium batteries after a string of onboard fire incidents.

This new rule targets uncertified portable chargers, which have been linked to several dangerous episodes this year. One of the most alarming cases occurred on an Air Busan flight, where a power bank caught fire mid-air, causing serious damage to the aircraft.

Since the rule took effect, airport authorities have already begun confiscating non-compliant devices. Travelers have reported long delays and confusion at security checkpoints, with the policy sparking debate on social media. Some travelers were unaware of the requirement, while others expressed concern over the lack of consistent enforcement prior to this ban.

This isn’t China’s first step in regulating unsafe power banks. A previous regulation banned the sale of uncertified models starting August 2023. The latest ban now extends that policy to all passengers attempting to board domestic flights with unverified devices.

The 3C mark is China’s national safety certification, similar to the CE mark in Europe. It confirms that electronic devices, including power banks, meet rigorous testing standards to prevent hazards like overheating or combustion. Power banks without this certification are now considered prohibited items on domestic flights.
