Short answer: Do not assume a foreign-bought power bank is exempt from China screening. If the device body has no readable 3C / CCC evidence, a mainland China flight can be high risk even when the bank is under 100 Wh. Check the exact device, recall status, Wh, carry-on rules, airline policy, and route.
Many travelers buy power banks overseas, then depart mainland China later. The hard part is that airport staff inspect the device in hand, not where it was purchased.
A foreign retail receipt, overseas certification mark, or brand reputation does not automatically solve China 3C / CCC evidence. If the body label cannot show the required evidence clearly, treat the trip as risky.
Before a China departure, use an exact-model check and keep capacity, model, and certification evidence readable on the device. When evidence is missing, pack a backup with clear body labeling.
Rule summary
- Purchase place
- Buying overseas does not create a China airport-screening exemption.
- Device proof
- Readable body-level 3C / CCC evidence is safer than receipts or brand claims.
- Capacity still matters
- Wh and carry-on handling still apply after certification evidence.
- Best action
- Use a clearly labeled, exact-model, non-recalled backup for China departure.

The final answer can change by model, airline, country, certification mark, label evidence, and recall status.

Can I bring a foreign-bought power bank without 3C on a China flight?
Treat it as high risk for mainland China departure if the device body has no readable 3C / CCC evidence, even when it is below 100 Wh.
Does buying the power bank outside China make it exempt?
Do not rely on that. Airport screening is based on the carried device, route, airline, recall status, and readable evidence.
What should I pack instead?
Use a power bank with readable body certification and capacity labels, exact model identity, no recall match, and carry-on-only packing.
