Recently, a video showing a power bank catching fire inside a subway station—burning a hole through a passenger’s jacket—has sparked widespread concern online. According to eyewitnesses, the shared power bank carried by a passenger suddenly began smoking and ignited, quickly setting the passenger’s outerwear on fire and burning a hole through it. Fortunately, no serious injuries were reported. Subway staff responded promptly, using a fire extinguisher to put out the flames and evacuating nearby passengers to ensure safety.Experts explain that such incidents are often caused by substandard battery cells, overcharging, deep discharging, or physical damage to the power bank. Low-quality or aged portable chargers are especially prone to thermal runaway under conditions like high temperature or compression, which can lead to spontaneous combustion or even explosion. Therefore, the public is advised to check whether their power banks—whether shared or personal—carry proper safety certifications and show signs of swelling, leakage, or other abnormalities. It’s also important to avoid leaving them in hot, enclosed spaces for extended periods.This incident serves as another reminder of public safety risks. Authorities have stepped up safety inspections of shared charging devices and urge commuters to remain vigilant—immediately moving away and alerting staff if a power bank shows signs of overheating or smoke.
近日，一则‘地铁站内充电宝自燃导致乘客外套被烧穿’的视频在网络引发广泛关注。据现场目击者描述，事发时一名乘客随身携带的共享充电宝突然冒烟起火，火势迅速蔓延至其外套，造成衣物局部烧穿，所幸未造成人员重伤。事件发生后，地铁工作人员迅速启动应急预案，使用灭火器扑灭明火，并疏散周边乘客，确保现场安全。专家指出，此类事故多因充电宝内部电芯质量不达标、过度充放电或物理损伤所致。尤其是一些劣质或老化严重的移动电源，在高温、挤压等环境下极易发生热失控，进而引发自燃甚至爆炸。因此，公众在使用共享或自有充电宝时，应留意产品是否有正规认证、是否存在鼓包、漏液等异常现象，并避免将其长时间置于高温密闭空间。此次事件再次敲响公共安全警钟。相关部门已加强对共享充电设备的安全监管，同时呼吁市民提高安全意识，一旦发现充电宝异常发热、冒烟，应立即远离并通知工作人员处理。
