How to stay safe as airlines crack down on power banks
"In late January, an Airbus A321 was running 20 minutes behind schedule as it prepared to taxi at Gimhae International Airport in Busan, South Korea. Then, a fire broke out in an overhead bin. The inflatable slides were deployed as all 176 people evacuated the Air Busan plane, although 27 of them were injured. The aircraft was destroyed by the flames. Authorities later said the fire was likely caused by a power bank after its insulation broke down."
"Power banks, laptops, and phones are all powered by lithium batteries. They pose a fire risk due to a process called thermal runaway: If the battery is damaged or overcharged, it can spark a chain reaction and a rapid rise in temperature. Two weeks after the incident in Busan, South Korea's transport ministry announced a ban on storing power banks and e-cigarettes in the overhead bins. It also said they could no longer be charged using a plane's USB ports."
An early-January fire on an Air Busan Airbus A321 at Gimhae International Airport destroyed the aircraft and injured passengers after a power bank's insulation failed. Inflatable slides were deployed and 176 people evacuated, with 27 sustained injuries. Lithium batteries in power banks, laptops and phones can trigger thermal runaway if damaged or overcharged, causing rapid temperature rises and fires. Several airlines and regulators have banned storing or charging power banks in overhead bins and blocked in-seat USB charging. The FAA recorded a sharp rise in verified lithium-battery incidents, increasing the frequency from under 50 annually pre-pandemic to roughly every four days.
