China bans power banks that are not certified and have been recalled from planes

China's aviation regulator has banned passengers from carrying power bank without Chinese safety certification marks, or those that have been recalled recently by manufacturers due to safety concerns.

This move applies to all passengers boarding flights in China. It follows a global series of incidents involving lithium batteries, such as power banks, and planes overheating.

A spare power bank could have been the cause of an Air Busan fire that occurred in January. In March, a Hong Kong Airlines flight flying from China to Hong Kong had to land in China because a fire broke out in an overhead luggage compartment.

When they are damaged or faulty, lithium batteries found in laptops, mobiles, electronic cigarettes, and power banks may short-circuit, causing extreme heat, smoke, or fire. As passengers bring more battery-powered devices on planes, they are becoming a greater concern for aviation safety.

The U.S. Federal Aviation Administration recorded three overheating incidents of lithium batteries in planes every two weeks last year, compared with just one a week during 2018.

China's Civil Aviation Administration announced on Thursday that power banks must clearly be marked with "3C", short for China Compulsory certification, which authorities require products that may impact health, safety and environmental protection.

This month, several leading power banks manufacturers in China such as Anker and Romoss recalled battery products because of safety concerns. China's market regulator revoked and suspended the 3C certification for several battery cell and power bank manufacturers.

Airlines around the world have tightened their power bank regulations since the Air Busan incident. Although aviation rules say that power banks are to be kept in cabin luggage, airlines have been banning them on board.

Since 2014, China has prohibited passengers from using power banks to charge devices during flights.
