As temperatures rise, many people rely on portable fans to cool off when outdoors or in the office. However, there are risks involved, such as batteries deforming and causing short circuits, leading to smoking or fire. The use of neck fans or handheld fans that contain lithium batteries may pose an explosion risk if mishandled. It's advised to avoid dropping or causing damage to the fan's battery, stop using it if cracks appear on the casing, and ensure it has proper safety certifications. Precautions include charging in safe locations away from flammable materials, avoiding charging while unattended or during sleep, and being cautious with the use of power banks to prevent accidents.
