Understanding the power bank flight rules are very important when flying in China. This guide explains all key points of carrying power banks on China flights, from official rules, 3C certification notes, differences between domestic and international flights, capacity limits to rules of different airlines and useful carry tips.
China Flight Power Bank Carry Rule
The most important rule to follow is: All power banks without valid 3C certification are not allowed on any planes. This rule applies to all China domestic flights and international flights departing from China.
Power banks with unclear 3C signs, broken shells or invalid 3C signs are also not allowed in carry-ons. Each passenger can only carry two qualified power banks at most, and they must be stored accordingly to the directions of flight attendants on the plane.
What Is Mandatory 3C Certification for Power Banks?
3C (China Compulsory Certification) is a necessary official document. All electronic products must have this document to be sold and used legally in China. Its main purpose is to make power banks follow unified national safety standards. This certification helps reduce serious safety risks such as battery overheating, short circuits and explosions on airplanes.
Uncertified power banks bring huge safety risks. They are strictly not allowed on any flights. Qualified power banks have a clear 3C label on their outer shell so that security staff can easily spot this mark.
China Power Bank Rules: Domestic and International Flights
Many passengers have a common question. They want to know if power bank carry rules are different for domestic flights and international flights. The fact is clear. The core rules are totally the same for both kinds of flights.
All flights that take off at Chinese airports follow the same 3C certification rules and capacity limits. For planes flying from abroad to China, no 3C inspection is required upon entry. However, it will be confiscated if you take China domestic flights later. Some foreign airlines may give extra reminders, but they still must obey China’s basic civil aviation rules.

Power Bank Capacity Limits (Wh) and Rules
Chinese civil aviation uses Watt-hour (Wh) to measure power bank capacity instead of using mAh as the only standard. The capacity rules are clearly written and strictly enforced.
Under 100Wh
Most common power banks for phones and small digital devices are in this range. Passengers can put them directly in carry-on luggage. No extra approval is needed.
Between 100Wh and 160Wh
For medium-capacity power banks in this range, passengers must get written approval from the airline before the flight.
Over 160Wh
High-capacity power banks are completely banned on all Chinese flights. There are no exceptions for any situation.
Most common portable power banks on the market have a capacity lower than 100Wh. As long as they have valid 3C certification, they can be taken onto planes legally.
China Airline Power Bank Implementation Rules
All mainstream airlines in China strictly follow the unified rules issued by Civil Aviation Administration of China. There are no big differences between different airlines.
Air China, China Eastern Airlines, Spring Airlines and Hainan Airlines all use the same capacity standards and certification rules. Some low-cost airlines only remind passengers to prepare power banks early for security checks. It is suggested that passengers check their airline’s official website one day before departure to avoid sudden extra notices for some special routes.
Essential Packing Tips for Power Banks
- Always put power banks in carry-on luggage. Never check them in with other luggage. Air pressure and temperature in the plane cargo hold change a lot. This can easily cause battery safety accidents.
- Protect power banks well. Do not break or damage their outer shells. Keep them separate from metal things like coins and keys. This can stop short circuit problems.
- Make sure the 3C mark and capacity label on power banks are clear and complete. This helps security staff check quickly. It also cuts down waiting time at security checks.
- Do not carry broken, old or unmarked power banks. One to two qualified certified power banks are enough for daily travel use.
What to Do If Your Power Bank Is Not Allowed
When you go through airport security checks and find that your power bank has no 3C certification or exceeds the allowed capacity limit, don't panic. You can handle the situation using one of the following three ways:
Mailing the Power Bank to Yourself
Most large airports have special SF Express service counters, such as Beijing Daxing International Airport and Hangzhou Xiaoshan International Airport.
The cost for domestic mail is about 20 to 50 yuan, and the cost for international mail is a little higher than domestic shipping. You can choose to send the power bank to your home address or your hotel address directly.
Voluntarily Discard the Power Bank
Special recycling bins for unqualified power banks are placed at each airport security checkpoint. You can put the unqualified power bank into these designated bins directly.
Airport staff will collect and dispose of these power banks in a unified and safe manner. You must not throw the power bank casually in other places at the airport, as this is not allowed.
Temporarily Store the Power Bank
This free storage service is available at major airports, including Beijing Capital International Airport, Shanghai Pudong International Airport and Shenzhen Bao’an International Airport. The free temporary storage time is 7 to 10 days.
You must remember to pick up the power bank by yourself within the storage period. If no one comes to claim it within the set time limit, the airport will dispose of the unclaimed power bank properly.
To find the storage spot, you can ask the on-site security staff about the “power bank temporary storage area”. For example, the storage point at Beijing Capital Airport Terminal 3 is located in the passenger service center inside the parking lot.
Tips for China Travel with Power Bank
- If you forget to bring a qualified power bank, you can buy legal ones easily at Chinese airports, convenience stores or electronics shops in big cities.
- Arrive at the airport 1-2 hours early for domestic flights. Arrive 2-3 hours early for international flights. Electronic security checks usually take more time.
- Put power banks in easy-to-reach pockets of carry-on luggage. This way, you can take them out quickly for security checks.
China’s flight rules for carrying power banks are clear and strictly enforced. The main goal is to keep flight safety. As long as you carry 3C certified power banks within the required capacity range, and prepare well following the tips above, you can pass security checks smoothly with no trouble. We wish all passengers a safe and comfortable trip in China.

Common Questions About China Power Bank Limits
Why is China so strict about power banks?
China enforces strict power bank rules mainly due to lithium battery fire risks. In 2025, multiple in-flight incidents and high unqualified product rates (43.6%) prompted CAAC to mandate 3C certification, matching international aviation safety standards to protect passengers and flights.How many power banks can I bring on flights in China?
You can carry a maximum of 2 power banks per person for personal use. Both must have valid 3C certification and meet capacity limits (≤100Wh without approval; 100-160Wh with airline written permission). They must be in carry-on luggage, not checked.Why do airlines not like power banks?
Airlines restrict power banks because their lithium-ion batteries pose fire/explosion risks. Unmonitored cargo holds can't quickly address fires; pressure changes and luggage impacts may destabilize batteries. Strict rules prevent catastrophic in-flight incidents and ensure cabin safety.Is a 20000mAh power bank allowed in flight in China?
Yes, if it has a clear 3C mark and ≤100Wh (typically 74Wh for 5V 20000mAh models). It counts toward your 2-unit limit. No airline approval needed. Must be in carry-on luggage; never check in. Uncertified or >100Wh units are banned.
