Since the beginning of this year, there have been frequent incidents of lithium battery products such as power banks carried by passengers catching fire and smoking on board.
Recently, the Civil Aviation Administration of China issued an emergency notice, banning passengers from taking domestic flights with power banks that do not have the 3C logo, have unclear 3C logos, or have recalled models or batches, starting from June 28.
What is the 3C logo? What are the rules for bringing power banks on planes?
What does the 3C logo look like?
How to judge authenticity?
3C certification (China Compulsory Certification, China Compulsory Product Certification) is a compulsory market access system implemented in accordance with the law in my country to protect the personal safety of consumers, national security and the environment.
According to national regulations, power banks that are officially on the market must obtain 3C compulsory certification.
Observe the 3C certification mark from the front facing the light. The mark has a white base plate and a black pattern. Aim at the logo screen and observe through the diamond shape of the 3C certification mark. The logo screen has a profound three-dimensional feeling and a sense of reality. If there is no three-dimensional effect, it can be judged to be a counterfeit logo.
Power bank boarding
Must meet capacity regulations
It should be noted that power banks that can be boarded on board must not only bear the 3C logo, but also comply with capacity regulations.
According to the "Announcement on the Regulations on Civil Aviation Passengers Carrying "Power Banks" on Boarding:
Power banks can only be carried in hand luggage or on your carry-on, and are strictly prohibited from being carried in checked luggage.
Power banks with a rated energy of no more than 100Wh do not require airline approval; power banks with a rated energy of more than 100Wh but no more than 160Wh can only be carried with the approval of the airline, but each passenger is not allowed to carry more than two power banks.
It is strictly prohibited to carry a power bank with a rated energy exceeding 160Wh. It is strictly prohibited to carry a power bank that does not indicate the rated energy and cannot calculate the rated energy through other marked parameters.
It should be noted that power bank is not allowed to be used to charge electronic devices during flight. For power banks with a start-up switch, the power bank should always be turned off during flight.
It reaches 400℃ in 15 seconds!
How dangerous is the spontaneous combustion of a power bank?
How terrible is it if a power bank catches fire? Previously, the Fire Rescue Brigade of Xiaoshan District, Hangzhou City, Zhejiang Province conducted an experiment on the fire of power bank.
The root cause of the fire in the power bank lies in the thermal runaway of its internal lithium battery. "A common cause of fires in power bank is internal circuit failure leading to a short circuit, which causes a fire." Firefighters said.
In the experiment, firefighters used tools to short-circuit the positive and negative poles of a power bank to simulate a short circuit. About 15 seconds later, the power bank began to smoke a lot, and the temperature quickly soared to over 400°C. "If there are combustible materials such as paper and clothing around, it may cause a fire." Firefighters emphasized.
It should be reminded that in the event of a short circuit, the power bank will continue to heat up. Common fire extinguishers are not very effective and cannot cool down the power bank, which may easily cause re-ignition. Therefore, the best way to put out a fire on a power bank is to use water.
When purchasing a power bank, you should look for the 3C logo
