Power bank suspected cause of fire on Air Busan flight

An investigation into a fire on an Air Busan plane in January suggests a portable power bank may have caused the incident. The fire started in the overhead compartment, injuring at least seven people. Preliminary findings indicate a breakdown in the power bank's insulation led to the fire. The device showed scorch marks, but the exact cause of the breakdown is still unknown. Following the incident, Air Busan banned power banks in onboard luggage. This move aligns with global airline regulations due to safety concerns over lithium-ion batteries.
