Who This Helps

  • Travelers flying domestically in mainland China.
  • Travelers carrying portable chargers or spare lithium batteries.
  • Travelers relying on phones for payment, translation, and maps.

Before You Start

  • Check whether the power bank has a clear CCC or 3C marking before packing for a China domestic flight.
  • Check whether the model or batch has been recalled or is visibly damaged, swollen, or unlabeled.
  • Find the Wh rating; if only mAh is shown, calculate or verify the Wh value before airport day.
  • Separate the rule layers: CCC marking is the China domestic-flight requirement, while Wh capacity is the aviation lithium-battery safety limit.
  • Keep power banks in carry-on luggage, not checked luggage.
  • Ask the airline before travel if any power bank is between 100Wh and 160Wh, because operator approval may be required.
  • Do not bring over-limit, damaged, swollen, recalled, or unclear-label batteries.
  • Charge your phone before security and carry a non-fragile backup plan if the power bank is refused.

Common Failure Cases

  • My power bank is a famous international brand. Check the visible marking and recall status before travel.
  • Security says the mark is unclear. Do not argue at the checkpoint; use airport disposal or storage options if available.
  • The official source and a platform or staff answer do not match. Follow the more authoritative official or on-site source, keep screenshots or documents, and choose the lower-risk fallback until the conflict is resolved.

Source cross-check

This answer was checked against CAAC: power banks without CCC markings prohibited on domestic flights and China Eastern Airlines: safety instructions for lithium batteries and dangerous goods. A third source, IATA: guidance to operators on power banks, was used where the answer depends on implementation detail or traveler-facing handling. Additional support from IATA: passengers travelling with lithium batteries was kept when official rules and platform execution need to be separated. Where sources use different scope or dates, the guide follows the current official or most directly authoritative source and keeps platform or traveler-facing material as implementation context only.

FAQ

Can I put a power bank in checked luggage?
No. Plan to carry power banks in hand luggage and follow battery rules.
Does CE or FCC marking replace CCC?
No. The CAAC notice specifically refers to CCC markings for the domestic-flight restriction.
