China has banned power banks lacking the mandatory “3C” certification from being carried on domestic flights. This ban, which took effect on June 28, 2025, is a direct response to a series of safety incidents involving lithium batteries on aircraft. Power banks without the “CCC” mark, those with unclear markings, or those on recall lists are prohibited. 中國已禁止未獲得強制性「3C」認證的行動電源在國內航班上攜帶。該禁令於2025年6月28日生效，旨在直接應對一系列涉及飛機鋰電池的安全事故。未獲得「CCC」認證、識別不清晰或被列入召回名單的行動電源均被禁止攜帶.

The “3C” certification mark on power banks, also known as the China Compulsory Certification (CCC) is a mandatory safety and quality certification required for products sold in China, including power banks. It signifies that the product meets specific safety standards and is safe for consumers. Recently, China has implemented stricter rules, requiring power banks on domestic flights to display this 3C mark, with some airlines even banning those lacking the certification. 

Here’s a more detailed explanation:
• What it is:
The 3C certification is a mandatory safety and quality certification system in China, similar to other international certifications like CE. 

• Purpose:
It ensures that products like power banks meet safety requirements, protecting consumers from potential hazards like overheating or fire. 

• Why it matters for power banks:
Due to incidents involving malfunctioning power banks, China’s Civil Aviation Administration has made it a requirement for power banks on domestic flights to display the 3C mark. 

• Consequences of non-compliance:
Power banks without the 3C mark, with unclear markings, or that have been recalled may be confiscated at airport security checkpoints and prohibited from boarding flights. 

• How to identify it:
The 3C logo is a specific mark that is printed on the product or its packaging. It may be accompanied by a unique code that can be used to verify its authenticity. 

• Scope:
This applies to both domestically manufactured and imported power banks sold in China
