Many people like to wear mini electric fans around their necks in the summer, so be careful because if dropped or hit hard, the lithium battery inside can deform and explode, causing facial burns.
On hot days, just leaving the air-conditioned room makes you sweat, many people have the habit of carrying a portable electric fan to cool down their body. Not many people know that this type of fan has a hidden mechanism. If subjected to strong impact, the battery inside can explode, causing unpredictable injuries to the body.
A few days ago, the fire department of Amagasaki city, Japan posted a warning video on its official YouTube channel, in which a model wearing a handheld electric fan around her neck suddenly exploded with a loud noise, causing many people around to panic and wonder why the handheld electric fan could explode.
The Amagasaki City Fire Department explained that they released the video because of the increasing number of electrical appliance fires nationwide. There have been many fires caused by batteries and chargers. Handheld electric fans are quite safe under normal use, but they can be dangerous if accidentally dropped or hit. The agency also recommends that people not charge the battery for too long.
Japan's National Institute of Technology and Evaluation (NITE) also warned that although portable electric fans are very convenient, there were 47 accidents reported from 2019 to 2021 due to this device, many of which involved victims wearing the fan around their neck, resulting in injuries to the face, neck, chest, and shoulders.
To use a portable electric fan safely, the most important product selection criterion is to choose a reliable manufacturer, importer or retailer. Especially in the case of online purchases, sometimes customers find it difficult to contact the manufacturer, the contact information is lost or only has overseas contact information.
If the handheld electric fan is dropped during use or subjected to a strong impact, the internal lithium battery may be deformed and lead to a short circuit; continued use of the product may cause a fire, or in more serious cases, an explosion. Therefore, if you feel any abnormality, stop using it and contact the manufacturer. If a worse situation occurs, such as an explosion or environmental impact, call the fire department immediately for assistance.
