China bans uncertified power banks on domestic flights – what travellers need to know

Flying within China just got stricter, especially if you’re packing a power bank. China has banned uncertified power banks from all domestic flights, triggering confusion and mass confiscations.

Why the sudden crackdown?

The Civil Aviation Administration of China (CAAC) imposed the emergency rule after rising fire risks linked to lithium battery packs. Recent aviation incidents, including a tarmac fire in South Korea, raised urgent concerns. Power banks can overheat under cabin pressure and catch fire in seconds—some reaching 400°C during in-flight incidents.

What makes a power bank “unacceptable”?

Only devices with China Compulsory Certification (CCC or 3C) are allowed on domestic flights. No 3C label? Security will confiscate it.

This regulation applies even if your power bank was bought before the 2023 certification rule came into force. A real 3C label is printed, not a sticker, and must be clearly visible on the power bank’s surface.

With only two days’ notice, passengers had little time to adjust. Thousands of power banks have already been seized at airport checkpoints. Airports now offer mailing options or discard zones, but travellers must handle rejected items on the spot.

What can you do to avoid confiscation?

• Before flying in China, check your power bank for a valid 3C mark.
• Stick to rated capacities under 100Wh to ensure safety and compliance.
• If unsure, buy your device from verified Chinese electronics retailers, not street vendors or unverified online sellers.

International flights: different rules apply

The ban currently affects only domestic flights within China. For international travel, power banks under 100Wh are generally accepted worldwide. Between 100Wh and 160Wh? Airline approval is required. Anything larger is banned.

But note: if you’re connecting within China to an international flight, the domestic rule still applies, no 3C certification, no power bank.

Power banks on trains and subways? Still OK for now

Trains and subways don’t follow the CAAC rules. Power banks under 100Wh with clear labels are still allowed on rail journeys. However, metro rules vary by city, some limit capacity, others limit quantity.

Impact on the tech industry

This rule could reshape the consumer electronics market in China. Manufacturers now face pressure to meet aviation safety standards and improve product quality. Expect a rise in certified, airline-approved power banks hitting store shelves soon.

To avoid surprises at security, check your power bank’s label and specs before you travel. China’s new policy may seem sudden, but it’s aimed at protecting passengers and planes from a very real fire risk.

When in doubt, pack smart, or leave it behind.
