PowerBank Pass / Travel guide

Mainland China.
Know which rule applies.

The route matters. So does the airline operating the flight.

01

International leg only?

The cited 3C notices specify domestic mainland-China flights. Do not infer a domestic requirement from arrival alone.

02

A domestic China leg?

Check for a clear 3C mark and recalls. The domestic leg still counts inside an international ticket.

03

Connection unclear?

Confirm the actual flight and security route with the operating airline. Forum anecdotes cannot guarantee entry.

Source checked 25 Oct 2026
Published rule
On domestic flights within mainland China, power banks without a 3C (CCC) mark, with an unclear 3C mark, or from a recalled model or batch are not allowed, from 28 June 2025.
Scope supported here
Domestic flights within mainland China, including a domestic leg of a longer trip. China Southern words the rule as applying to power banks manufactured in China.
Effective from
28 Jun 2025

Departure requirements and the operating airline’s onboard policy can be different. This record only applies to the scope shown above.

Read the label · Official guidance

The label has rubbed off. Will a photo or receipt work?

Do not assume it will. Cebu Pacific says unclear or missing specifications can lead to refusal. A receipt, product page or saved photo may help you explain the model, but the sources we checked do not guarantee these will replace a readable label on the device. Ask your operating airline before departure.

Your route · Official guidance

I connect in China. Do I need the 3C mark?

The cited airline notices apply the 3C requirement to domestic flights within mainland China, including a domestic leg inside an international itinerary. An international arrival or departure alone does not establish that requirement. Check every flight segment, your security route and the physical mark; a missing or unclear mark is a problem for a domestic leg.

Your route · Practical suggestion

Which airline do I choose for a codeshare flight?

Start with the airline shown as “operated by” on your booking. Add each flight separately. The airline that sold the ticket and your destination country do not by themselves tell you the onboard rule. Confirm a codeshare or unusual connection with the operating airline if its published policy is unclear.

How do I know whether my model is recalled?

Check the manufacturer’s official recall page using the exact model and, when required, serial or batch number. The FAA prohibits damaged or recalled batteries likely to create a dangerous evolution of heat. This site does not maintain a complete model-by-model recall database; a green capacity result is not a recall check.
