Power banks can catch fire even when unused

Power banks have faced increased scrutiny due to recent fire incidents, including a plane fire in South Korea and a train fire in Singapore. Experts warn that these devices can catch fire even when not in use, especially if they have defects or are exposed to temperature changes. To prevent fires, users should avoid keeping power banks in bags while charging and ensure they are used in cool, well-ventilated areas. Signs of a faulty power bank include rapid battery drain, deformation, or unusual heat. When purchasing a new power bank, look for safety features like overcharge protection and thermal cut-off. In Singapore, suppliers must comply with safety standards, but pre-market approval is not required. Non-compliant suppliers may face fines or imprisonment.
