The reporter noticed that some of these unqualified mobile power supplies have prominent capacity issues and cannot achieve the claimed charging effect; Some pose safety risks such as heat generation and explosion, posing a threat to the personal and property safety of consumers. According to industry data, China is not only the world's largest producer of mobile power, but also the largest consumer market. Since 2020, the shipment volume has remained at around 100 million units. With the increasing popularity of mobile power sources, safety accidents caused by mobile power sources have occurred from time to time across the country.
At the end of May this year, on Line 7 of the Beijing Metro, a mobile power supply inside a passenger's backpack suddenly exploded, and a large amount of thick smoke instantly filled the entire carriage. Fortunately, due to timely handling by the staff, the accident did not cause any casualties.
In May of this year, a mobile power source left behind in a car in a parking lot in Zhangjiagang, Jiangsu also exploded. The center console inside the car is severely damaged, and there are signs of explosion on the front windshield.
In early January this year, a self built residential building in Guiping, Guangxi, caught fire in the early hours of the morning, resulting in the unfortunate death of a family of four inside. According to a warning article released by the fire department, "After preliminary investigation, the cause of the fire was a short circuit in the mobile power supply, which caused the fire. On site inspection found that the mobile power supply was suspected to be a counterfeit product."
Industry experts say that poor quality or improper use of mobile power sources can lead to safety accidents and threaten the personal and property safety of consumers.

5 batches of mobile power supply overcharge detection failed
May cause fire and explosion
It usually takes several hours or even longer to fully charge a mobile power supply. If you forget to unplug the power, you may also experience charging all day and all night, which is called overcharging. During this national supervision and random inspection, it was found that 5 batches of mobile power supplies failed the overcharging test.
According to the testing engineer, mobile power supplies may forget to unplug the power and charge for a long time during daily use. This 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 internal battery cells of mobile power sources suddenly explode during the test, emitting a large amount of thick smoke. After the experiment, all of these unqualified mobile power supply cells were burned out.
After testing, 5 batches of mobile power supply overcharging projects were found to be unqualified, which are:
Shenzhen Jinyu Dongfang Industrial Co., Ltd. produces energetic and cute mobile power supplies for the Tmall Lovet flagship store
Dongguan Yubo Communication Equipment Co., Ltd. produces Yubo Mobile Power Supply for Vipshop Yubo Digital Special Flagship Store

Shenzhen Yimo Technology Co., Ltd. produces LeEco Super Mobile Power Supply for Pinduoduo LeEco Yandian Specialty Store
Yuantu Culture Co., Ltd. produces Starry Sky Warm Hands Treasure for Tmall Tianxiang Creation Flagship Store
According to the testing engineer, poor battery cell quality is often one of the main reasons for unqualified overcharging indicators.
The reporter learned that if the quality of the shell is not up to standard, once it is bumped or dropped, the internal circuits and battery cells of the mobile power supply cannot be effectively protected, resulting in short circuits, battery cell leakage and other problems, which may also cause safety accidents such as fire and explosion.
The State Administration for Market Regulation requires local market supervision bureaus to urge e-commerce platforms to immediately remove and handle unqualified products discovered through supervision and spot checks. At the same time, measures such as sealing and seizure shall be taken 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 reviews.
