Core Viewpoint - The article discusses the safety concerns related to power banks, particularly focusing on incidents of self-ignition and explosion, and provides guidelines for safe usage and storage [1][3]. Group 1: Incident Overview - On March 14, Shenzhen Airlines reported an incident where a passenger's power bank caught fire during taxiing, but the crew managed to control the situation effectively [1]. Group 2: Causes of Self-Ignition and Explosion - Poor quality products, particularly substandard battery cells and circuit boards, can lead to power bank self-ignition and explosions [3]. - Overcharging can occur if a power bank is left plugged in for too long, leading to potential circuit failures and explosions [4][5]. - Inadequate heat dissipation, such as charging in confined spaces or high-temperature areas, can also trigger self-ignition [6]. - Physical damage from impacts or pressure can misalign internal components or cause battery leakage, increasing explosion risks [8]. - Exceeding the battery's usable life, indicated by a cycle count, can lead to abnormal behavior and self-ignition risks [9]. Group 3: Safe Usage Guidelines - Users should avoid heavy pressure or strong vibrations on power banks to prevent short circuits or explosions [10]. - Power banks should be stored in well-ventilated areas, away from direct sunlight and moisture [11]. - It is advisable to use original or compatible charging plugs to ensure safety [12]. - Users should avoid prolonged charging of power banks and cease use if overheating, unusual sounds, or deformation occurs [13].
