Thanks to CTOnews.com netizen MissBook for the clue delivery! CTOnews.com, November 21, according to CCTV news, the results of the latest state supervision and inspection of mobile power sources released by the State Administration of Market Supervision show that 1/4 of the products tested are unqualified, and the main problems found are hidden dangers such as electricity leakage and fire.

According to Miao Yuchen, director of the product sampling department of the quality Supervision Department of the General Administration of Market Supervision, 108 batches of mobile power products produced by 107 enterprises in 9 provinces (cities) were selected and found that 27 batches of products were unqualified, and the unqualified discovery rate was 25%. It has been tested that the unqualified items focus on five items: conversion efficiency, effective output capacity at room temperature, heat abuse, overcharging and radio disturbance.

The State Administration of Market Supervision and Inspection found that eight batches of mobile power overcharging tests were unqualified, and the unqualified products were produced by enterprises such as Shenzhen Harman Technology Co., Ltd., Shenzhen Baojia Energy Co., Ltd., and Shenzhen Yimou Technology Co., Ltd. The overcharging project is to examine whether there is a risk of fire and explosion when the internal battery is continuously charged by over-voltage and over-current when the protection function of the mobile power supply fails. Unqualified overcharging may lead to fire and explosion of mobile power supply, threatening the personal and property safety of consumers.

In addition, among the 15 batches of unqualified mobile power supplies, 9 batches of heat abuse failed, and this project is also the project with the largest number of unqualified products detected by the country. the nominal production units of unqualified products are Shenzhen Fushun Cheng Technology Co., Ltd., Dongguan Bester New Energy Technology Co., Ltd., Shenzhen Shixailai Technology Co., Ltd., and other 9 enterprises. The heat abuse project examines the high temperature resistance of the internal battery of the mobile power supply. (unqualified) the mobile power supply may cause a fire and explosion when it encounters a high temperature environment in the course of use, and there are certain safety risks, such as the temperature inside the car will be particularly high in summer. If the mobile power supply is kept in the car, then its environment belongs to the high temperature environment.

This time, the national pump also found that 9 batches of mobile power supply projects with effective output capacity at room temperature were not up to standard. they are mobile power supplies produced by nominal production units, such as DiFule Biology (Shanghai) Co., Ltd., Guangzhou Xinjiang Sea Technology Co., Ltd., Shenzhen Shixailai Technology Co., Ltd., etc. Among them, when the rated capacity claimed by some manufacturers is 4000 Ma, and the measured output capacity is 2160 Ma, which is only more than half of the nominal value, it is the most serious product with false standard of rated capacity found in this national pump.

CTOnews.com learned that since the implementation of the national standard for mobile power supply in 2019, the General Administration of Market Supervision has carried out state supervision and spot checks on such products for three consecutive years. The testing engineer said that if the mobile power supply safety project is unqualified, it means that the product has the risk of overheating, fire, explosion and so on, and there are serious safety risks.
