China’s CCC/3C power bank rule has created understandable confusion among international travelers.
The rule is well known for domestic flights within China. But what happens if you’re simply flying through China on an international journey? Could airport security confiscate a perfectly good overseas power bank just because your connecting flight departs from a Chinese airport?
A traveler planning an Air China journey from Italy via China recently asked exactly that question.
We put it to the ChinaTravelBUG AI-assisted Travel Planner.
Here is the Planner’s unedited answer.
AI Travel Planner Answer
Yes — if your Air China journey is Italy → China → another country, and both sectors are international, the CCC/3C logo requirement is not currently stated as applying simply because you connect at a Chinese airport.
I checked the current rules rather than relying on the screenshot. The Civil Aviation Administration of China (CAAC) rule, effective since 28 June 2025, specifically prohibits power banks without a clear CCC/3C mark on “境内航班” — domestic flights within China. Air China’s own notice uses exactly the same wording. ()
So, for example:
Rome → Beijing → Tokyo: the CCC requirement should not apply merely because you transit Beijing.
Rome → Beijing → Xi’an: different situation. Beijing → Xi’an is a domestic Chinese flight, so your power bank must have a clear CCC/3C mark and must not be from a recalled model/batch. International-to-domestic connections also require you to pass through Chinese security again. ()
There are still normal Air China battery rules on international flights. Power banks must travel in carry-on baggage, never checked baggage. Air China currently permits power banks up to 100 Wh under the normal rules; 100–160 Wh requires airline approval, and anything over 160 Wh is prohibited. Air China also says power banks cannot be used to charge devices during the flight and must not be stored in the overhead compartment. ()
What I’d do
If you’re international → international through China, I would be comfortable taking a normal, reputable power bank without CCC certification, provided its capacity/Wh marking is clearly visible.
If there’s any domestic Chinese flight segment, I would take a CCC-marked power bank instead. That’s the easiest way to avoid having it confiscated at security.
If you give me the exact routing — Italy → which Chinese airport → final destination — I can check the connection procedure at that airport too.
ChinaTravelBUG’s Take
The most important point here is simple:
Transiting through China and taking a domestic flight within China are not the same thing.
That’s where much of the confusion surrounding the CCC power bank rule comes from.
Think about these two journeys:
Rome → Beijing → Tokyo
Both flight sectors are international.
Rome → Beijing → Xi’an
The second flight is a domestic Chinese flight.
Under the current published rule, it’s the second scenario where the special CCC/3C requirement becomes important.
Don’t Forget the Other Power Bank Rules
CCC certification isn’t the only thing travelers need to think about.
Even when the CCC requirement doesn’t apply, airline rules concerning lithium batteries, capacity and storage still do.
In particular, don’t put your power bank into checked luggage simply because you’re worried about airport security. Power banks belong in carry-on baggage, subject to the applicable airline rules.
And check the markings on the power bank itself. If its capacity or Wh rating is worn away or impossible to read, that can create another avoidable problem.
Why This Matters for China Travelers
This is a good example of why a small detail in your itinerary can completely change the answer to a travel question.
“I’m connecting through China” isn’t quite enough information.
The important question is:
Where does your next flight go?
That’s why travelers should be careful about applying advice from someone else’s itinerary to their own. A rule affecting a traveler flying Beijing → Xi’an may not apply in exactly the same way to somebody flying Beijing → Tokyo.
A Note About AI Travel Advice
The AI Travel Planner answer above is reproduced unedited.
Aviation and security regulations can change, and individual airlines may impose additional requirements. Before flying, check the latest CAAC rules and your airline’s current power bank/lithium battery policy, particularly if your journey includes a domestic flight within China.
For something as easy to verify before departure as a power bank, it’s better to check twice than lose it at airport security.
