The results of the random inspection showed that among the 99 batches of products produced by 95 enterprises in 9 provinces (cities), 35 batches failed, and the failure rate was 35.4%.

Some of these unqualified mobile power supplies have prominent problems with false capacity and cannot achieve the claimed charging effect; some have safety risks such as heat generation and deflagration, threatening consumers’ personal and property safety. According to relevant industry data, our country is not only the world’s largest producer of mobile power supplies, but also the largest consumer market. Since 2020, shipments have remained at about 100 million units. With the continuous popularization of mobile power supplies, safety accidents caused by mobile power supplies have occurred all over the country.

At the end of May this year, on Line 7 of the Beijing Subway, the mobile power supply in a passenger’s satchel suddenly exploded, and a large amount of smoke instantly filled the entire carriage. Fortunately, due to the timely handling of the staff, the accident did not cause casualties.

Also in May this year, in a parking lot in Zhangjiagang, Jiangsu Province, the mobile power supply left in the car also exploded. The center console inside the car was badly damaged, and there were traces of bursting in the front windshield.

In early January this year, a self-built house in Guiping, Guangxi Province, burst into flames in the early morning, and a family of four died tragically. According to a warning article issued by the fire department, "After preliminary investigation, the cause of the fire was a short circuit of the mobile power supply, which caused the fire. The on-site inspection found that the mobile power supply was suspected to be counterfeit and shoddy products."

Industry experts say that poor quality or improper use of mobile power supplies can lead to safety accidents, threatening consumers’ personal and property safety.

It generally takes a few hours or even longer for the mobile power supply to be fully charged. If you forget to unplug the power supply, you may also charge it all day and night. This situation is called charging. During this national supervision and spot inspection, it was found that 5 batches of mobile power supplies failed the charging test.

According to the testing engineer, during daily use, a mobile power supply may forget to unplug the power supply for a long time to charge, which requires that the internal battery quality of the mobile power supply must be reliable enough. Even if the circuit is damaged during overcharging, there should be no risk of fire or explosion.

Some mobile power internal battery in the test process suddenly deflagration, a lot of smoke. After the test of these unqualified mobile power batteries were burned.

After testing, 5 batches of mobile power overcharging items failed this time. They are:

Shenzhen Jinyu Dongfang Industrial Co., Ltd. produces the Yuanqi Mengmeng mobile power supply of Tmall Lofte flagship store

Dongguan Yubo Communication Equipment Co., Ltd. produces Yubo mobile power supply for Vipshop Yubo Digital Sale Flagship Store

Shenzhen Yanbu Technology Co., Ltd. produces super flash charging (mobile power supply) for Tmall eara flagship store.

Shenzhen Yimo Technology Co., Ltd. produces the LeTV super mobile power supply of Pinduoduo LeTV Yandian store

Yuantu Culture (Shenzhen) Co., Ltd. produces the Starry Sky Hand Warmer of Tmall Tianxiang Chuangwu Flagship Store

According to the testing engineer, poor battery quality is often one of the main reasons for the failure of the overcharge index.

If the shell quality is not up to standard, in the event of a bump or drop, the internal circuit and battery of the mobile power supply cannot be effectively protected, causing problems such as short circuit and battery leakage, which may also lead to safety accidents such as fire and deflagration.

For unqualified products found in supervision and spot checks, the General Administration of Market Supervision requires local market supervision bureaus to urge e-commerce platforms to immediately remove them from the shelves, and at the same time take measures such as seizure and seizure in accordance with the law to strictly prohibit the production and sales of enterprises. For unqualified enterprises, further clarify the rectification requirements, strictly supervise the implementation of rectification measures, and organize timely review.
