Many Vietnamese travelers prepare their China visa, flight tickets, hotel, and China travel SIM very carefully before departure. However, there is one new rule that not everyone knows about:
Some power banks may be refused for carry-on or may be held during security screening in China.
This is especially important for anyone planning domestic flights between cities such as Beijing, Shanghai, Guangzhou, Shenzhen, Hangzhou, or Chengdu.
When traveling in China, your phone is not only a communication device but also a tool for payments, ride-hailing, map searches, and daily internet use.
So, can you bring a power bank to China?
The answer is yes, but not every type is accepted.
At present, China is strengthening checks on lithium batteries and power banks carried in hand luggage. Products with unclear origin, no proper certification, or blurred technical information may have trouble passing security screening.

In particular, if you plan to take domestic flights within China, the checks are often stricter than in many other countries.
What is CCC certification?
CCC (China Compulsory Certification), also known as 3C certification, is a mandatory standard for many electronic products sold in China.

For power banks, many airports now require the product to have full identification information, clear origin details, and to meet related safety standards.
You can check the back or side of the power bank for the CCC or 3C logo.
Types of power banks that are more likely to cause issues during checks when traveling in China
Travelers should be careful if they are using:
- Unbranded power banks.
- Generic products with no specifications.
- Battery capacity cannot be identified.
- Peeling labels or faded information.
- Very old products whose origin can no longer be identified.
If you are using a power bank model that is several years old, you should check it again before your trip.
Power bank capacity allowed on flights
In addition to safety standard requirements, passengers must also comply with general aviation regulations:
- Under 100Wh: allowed in carry-on baggage.
- From 100Wh to 160Wh: airline approval required.
- Above 160Wh: not allowed on board.
- Power banks are not allowed in checked baggage.
Most 10.000mAh and 20.000mAh power banks today are within the permitted limit.
What should you check before traveling to China?
Before your departure date, take a few minutes to check:
✓ Your passport and visa are still valid.
✓ The power bank has complete information and clear identification.
✓ The battery capacity is within the allowed limit.
✓ The power bank is packed in your carry-on luggage.
✓ You have prepared internet access to use as soon as you arrive in China.
Don’t forget to prepare a China travel SIM
One thing many travelers often overlook is internet access. In China, many familiar services such as Google, Gmail, Facebook, Instagram, WhatsApp, and YouTube may be restricted. Therefore, preparing a China travel SIM or China eSIM before departure will make things much more convenient for you.
With an internet connection, you can:
- Pay with Alipay or WeChat Pay.
- Use Didi ride-hailing.
- Check maps.
- Translate Chinese in real time.
- Contact your hotel and tour guide.
- Book high-speed train tickets and attraction tickets.
Many travelers choose a China eSIM because it can be installed right in Vietnam, without removing a physical SIM card, and used as soon as the plane lands.
Practical China travel experience from Simpm
Through supporting customers traveling to China, Simpm has found that most people pay attention to visas, hotels, and itineraries, but pay less attention to regulations related to power banks.
Meanwhile, this is an extremely important item because phones are used almost continuously throughout the trip.
A compliant power bank together with a stable China eSIM package will give you much more peace of mind while exploring the country of 1.4 billion people.
Conclusion
If you are preparing to travel to China, remember to check your power bank carefully before your flight. Products with unclear origin or that do not meet safety requirements may cause trouble when checking in or traveling on domestic flights.
In addition, don’t forget to prepare a China travel SIM or China eSIM so you have internet as soon as you arrive.
With just a few minutes of preparation before your trip, you can avoid many hassles and enjoy your journey more fully
