充电宝起火如何扑救？还有这8大误区必须知道

Core Viewpoint - The safety issues surrounding power banks have raised public concern due to incidents of fires and explosions caused by quality problems or improper use. Group 1: Fire Safety and Extinguishing Methods - Power banks are typically composed of several lithium batteries, and even if one battery's fire is extinguished, residual heat can ignite adjacent batteries [1] - Firefighters' experiments indicate that dry powder extinguishers are not effective against power bank fires, while water can penetrate the device and effectively cool it down [1] Group 2: Common Misuse and Safety Precautions - Users should recognize eight common misuse scenarios and ensure that power banks have the 3C certification when purchasing [1] - It is crucial to stop using a power bank immediately if it shows signs of swelling, overheating, or smoke [1] Group 3: Charging Practices - Overcharging can keep the battery cells at high voltage, accelerating aging and increasing fire risk; users should unplug once fully charged and avoid overnight charging [10] - High temperatures and humidity can destabilize battery cells, and power banks should be stored away from direct sunlight and heat sources [14] Group 4: Quality and Maintenance - Users should select power banks from reputable manufacturers and check for product packaging information, anti-counterfeiting codes, and the 3C mark to ensure quality and safety [5] - Using non-original charging cables can lead to poor contact and unstable current, increasing the risk of overheating and short circuits; original cables should be prioritized [23] Group 5: Signs of Damage - Signs such as swelling or damage indicate that the battery cells are compromised, and continued use may lead to explosions; users should stop using the device and keep it away from fire hazards [28] - Power banks have a lifespan indicator, and using them beyond their intended period can lead to reduced capacity and frequent overheating [32]
