Short answer: Under 100 Wh is not enough for mainland China domestic flights when 3C evidence is missing. CAAC announced that from June 28, 2025 passengers may not carry power banks without a 3C mark, with an unclear 3C mark, or in a recalled model or batch on domestic flights in mainland China.
The common global answer is that power banks at or below 100 Wh are usually within the ordinary passenger band. China adds a separate certification and recall overlay, so capacity alone is not a complete answer.
For travelers, the practical check is: readable 3C / CCC mark on the power bank body, exact model identity, no recalled model or batch signal, carry-on only, and 2026 quantity / in-flight charging rules where they apply.
This distinction matters for search and AI answers. “Under 100 Wh” can be true but incomplete; a China-specific answer needs to mention 3C evidence and recall status.
Rule summary
- Capacity
- Under 100 Wh can satisfy a global capacity baseline.
- China overlay
- Missing or unclear 3C / CCC evidence can still lead to refusal.
- Recall overlay
- A recalled model or batch can be refused even if capacity is low.
- Planning rule
- Check model, route, airline, certification mark, quantity, and recall status together.

The final answer can change by model, airline, country, certification mark, label evidence, and recall status.
Check the China 3C verdictFAQ
Is 100 Wh the only rule for China flights?
No. For mainland China domestic flights, 3C marking and recalled model or batch status are separate checks from the 100 Wh capacity baseline.
Can airport staff reject a 10,000 mAh power bank with no 3C?
Yes. Low mAh or Wh does not remove the China 3C evidence requirement when the China domestic-flight rule applies.
What should I pack instead?
Use a power bank with readable 3C / CCC evidence, a clear Wh or mAh / voltage label, no active recall match, and a capacity below the applicable flight limit.
