The Answer, Briefly
On domestic flights in China, passengers may not carry power banks that lack a valid CCC marking (often called a 3C mark), have an unclear CCC mark, or belong to a recalled model or batch. The Civil Aviation Administration of China introduced the restriction from June 28, 2025. A power bank must also comply with lithium-battery capacity and airline rules, and it belongs in carry-on baggage rather than checked baggage.
For an international visitor, the crucial distinction is the flight segment. A power bank accepted on an international flight into China is not automatically accepted on a later domestic flight from Shanghai to Zhangjiajie, Beijing to Xi’an or Chengdu to another mainland city.
AVIORA Planning Lens
Separate Official Rules From Practical Trip Support
Recheck date-sensitive government, airline, railway and attraction rules close to departure.
Keep passport details consistent across bookings and carry the documents needed for verification.
Build a backup for payments, connectivity and disrupted transport instead of relying on one app.
The China-Specific CCC Rule
The CCC mark is China’s compulsory product-certification mark. CAAC’s notice applies to domestic flights and prohibits three categories of power bank:
- a unit without a CCC mark;
- a unit whose CCC mark cannot be read; and
- a model or batch that has been recalled.
The rule is about the product in hand, not the traveler’s nationality or where the device was purchased. Many overseas power banks were manufactured for markets that did not require a printed CCC mark. Genuine quality, a familiar brand or an airline acceptance on another route does not replace the label requirement for a Chinese domestic security checkpoint.
Inspect The Power Bank Before Leaving Home
Find The Physical CCC Mark
Look on the case for the stylized CCC logo. It needs to be printed or otherwise permanently marked and readable. A product webpage, purchase receipt or photo of another unit is not the same as a visible mark on the device.
Do not add a homemade sticker or printed logo. Airport security decides whether the actual power bank complies, and a false certification mark creates a more serious problem than traveling without a battery.
Check The Watt-Hour Rating
The label should also show capacity. Airlines and security staff need a readable watt-hour value or enough electrical information to determine it. If a label lists milliamp-hours and voltage, the calculation is:
watt-hours (Wh) = milliamp-hours (mAh) × voltage (V) ÷ 1,000
For example, 20,000 mAh at 3.7 V equals 74 Wh. The arithmetic helps a traveler understand the label; it does not cure a missing CCC mark or guarantee carriage.
Check Recalls And Damage
Do not fly with a recalled, swollen, cracked, leaking or unusually hot power bank. Search the manufacturer’s current recall page using the exact model and batch information. If the label has worn away, replace the unit before the trip rather than hoping one airport will interpret it favorably.
