There are many reasons for the fire of mobile phone chargers

In recent years, the number of fires caused by mobile phone charging has been relatively large.

In August 2020, a resident of a shop in Guiyang charged his mobile phone in bed, and the inferior charger equipment failed to ignite combustible materials such as bed sheets, and eventually the fire spread, and all 7 people living in the accommodation areas on the mezzanine, second floor and third floor of the shop were killed.

In July 2021, the charger that was being charged in Mr. Li's home in Nanyang, Henan Province, suddenly exploded and caused a fire, from the small Mars to the whole house burning, taking only 3 minutes.

On February 16 this year, when a man in a community in Runzhou, Zhenjiang, was taking a lunch break at home, the charger of the mobile phone that was charging suddenly caught fire, and the man found that he had failed to use water to extinguish it and caused the fire to intensify.

"There are many reasons for a phone charger fire." Li Pengzhong, an engineer in the electronic engineering department of Weikai Detection Technology Co., Ltd., explained that for example:

Due to a single fault (such as component short circuit, open circuit, etc.) or abnormal operation (such as output overload, output short circuit, etc.) caused by too high temperature, it will cause the charger to catch fire;

The output transient voltage of the mobile phone charger is too high, which breaks through the battery protection circuit on the mobile phone and will also cause the battery on the mobile phone to catch fire or even explode.

In addition, in order to reduce costs, some companies use materials for plastic shells, components and other parts that are not effectively flame retardant, which will also cause the rapid spread of fire.

Original charging head is preferred

Shop third-party brand charger "Six Notes"

Based on the above problems, many consumers have doubts about purchasing and using third-party brand mobile phone chargers.

Xing Jingfang, executive deputy secretary general of the Consumer Electronics Service Professional Committee of the China Electronics Chamber of Commerce, told the China Consumer Daily reporter that in general, the charger should not be mixed: "First of all, the charging head should use the original, because the power of different charging heads is different, and the use of high-power charging heads to charge small-power products, although the speed is fast, it will hurt the battery." The same is true for data cables, it is best to use the original data cable, which can avoid security risks. ”

"For third-party brand chargers, there is no need to talk about tiger color change." Li Pengzhong said that mobile phone chargers belong to the products within the scope of the national CCC mandatory catalog, and consumers should check whether the CCC logo is printed on the product and the outer packaging when purchasing. Consumers should not blindly pursue low prices when buying, well-known brands have higher security and may have a better user experience.
