Short answer: For mainland China domestic flights, an unclear 3C / CCC mark is a real screening risk. CAAC includes unclear 3C marks alongside no-3C and recalled model or batch issues, so a power bank can be refused even when it is under 100 Wh.
Travelers often assume a faint or scratched mark is close enough. For China domestic screening, that is not a safe assumption because the checkpoint must be able to read the certification evidence on the device.
CAAC explicitly names power banks with unclear 3C marks in the prohibited-carry scope for mainland China domestic flights. That makes label legibility a separate issue from Wh, mAh, and ordinary carry-on-only handling.
Before travel, inspect the device under good light, photograph the label for your own records, and prepare a backup power bank if the 3C / CCC mark or model text cannot be read clearly.
Rule summary
- Unclear mark
- A worn, scratched, or unreadable 3C / CCC mark can be treated as high risk.
- Capacity is separate
- Under 100 Wh does not fix unclear certification evidence.
- Recall still matters
- Model or batch recall status is another independent check.
- Practical move
- Use a device with readable body labeling before a China domestic flight.

The final answer can change by model, airline, country, certification mark, label evidence, and recall status.
Check an unclear 3C markFAQ
Is a faded 3C mark enough for a China flight?
Do not count on it. If airport staff cannot read the 3C / CCC evidence, the device can be treated as high risk for a mainland China domestic flight.
Can I show a photo of the 3C mark from before it was scratched?
A photo may help you explain the device, but do not rely on it as a substitute for readable evidence on the power bank body.
Should I replace a power bank with an unreadable 3C mark?
For China domestic flights, the safer option is to use a power bank with clear body labeling, readable capacity, and no recall match.
