The security problem of mobile power has been receiving much attention. Today we don't talk about the explosion of various mobile power sources. I don't know what dangerous behaviors of mobile power in use, just one thing: At the end of 2014, the Jiangsu Provincial Bureau of Quality and Technical Supervision conducted a random inspection of 60 batches of mobile power, and all the results were unqualified! Why? Let's take a look at the mobile power that participates in the monitoring. According to the data released by Jiangsu Quality and Technical Supervision Bureau, there are 60 batches of products monitored, of which 34 batches are from e-commerce platforms, and 26 batches are from physical stores (including: specialty stores, supermarkets, electronic cities). Wait). There are 47 mainstream brands including EAGET, Coolby Rubik's Cube, DBK Dibike, MI Millet, etc. The brand covers all grades of products, ranging from 40 yuan to 378 yuan. Since the monitoring is not the mobile power of the cottage, and there are brand products that we are familiar with, and the purchase channels are basically reliable, then the quality result of the monitoring is not a fake and shoddy product. Mobile power test items and standards This mobile power quality monitoring is based on the CIAPS0001-2014 "USB interface mobile power" standard and the AQSIQ spot check program. The monitoring items include power supply capacity, conversion efficiency, voltage and current, and during use. There is no problem with the monitoring basis, such as fever and some basic safety protection functions. The summary of the results of the mobile power inspection project can be seen from the summary of the inspection project results. Different mobile power products have different performances in various monitoring projects. The compliance rate ranges from 0% to 100%, but overall there is still no one. The product can pass all the test items, so it seems that the quality problem of the mobile power supply may be really serious. Don't worry about the conclusion, I ZOL also conducted a horizontal evaluation of mobile power in December. Although there are no more than 60 models in 13 products, it can also explain some problems well. According to the results of the mobile power cross-evaluation, in addition to individual products, most brands of mobile power can provide better power support, and have a good performance in terms of functional usability. As a result, there has been a big problem. Our evaluation and mobile power monitoring results are very different. This is exactly where we need to figure it out. The summary of the results of the inspection project is mainly divided into two major categories. Among the inspection items affecting product safety, only the compliance rate of the enclosure fire rating is 55%, and the other safety inspection items are 100%. This and us The horizontal evaluation results are basically the same. Most of the unqualified products of the products are basically in the monitoring project that affects the performance of the products. The compliance rate of some projects is surprisingly low, and the best performance is only 81.7%. Among them, the appearance and size of one item put down all the products, the pass rate is 0, then we will take a look at the test results. Mobile power monitoring results “risk monitoring results show that 16 batches of 60 batches of samples are not marked with size, 1 batch of samples have no remaining capacity indicating function, 55 batches are not marked with safety warning signs or symbols, and 22 batches of products are used. The English logo, 60 batches of products are not marked according to the rated capacity specified by the standard. Only 5 batches of samples are marked with safety warnings or symbols. The rated capacity marked on all samples is the battery energy defined in this standard, not the rated capacity defined in this standard; only one batch of samples indicates the rated capacity, but the unit used is Wh instead of the mAh specified in this standard. Nor does it meet the standard requirements. Up to 22 batches using the English logo, accounting for 36.7% of the total. In addition, the metal casing of some samples is not chamfered and may scratch the user's skin. & rdquo; Product PN-913 mobile power labeling information From our horizontal evaluation test, in addition to PNY mobile power supply does not have Chinese manual and label, other products clearly indicate the product size and safety warnings in the package or manual. In line with the mobile power standard, all metal casing products are also chamfered and feel good. The problem may be that some products only indicate the cell capacity (mAh) or cell energy (Watt time), while some small brands or cottage mobile power supplies are not marked. In addition, “55 batches of unmarked safety warnings or symbols” may be wrong. If the product is improperly used, it may cause damage to the product itself or may endanger personal and property safety. Safety warning instructions or symbols should be used. (This item is allowed to be marked on the smallest package of the product) & rdquo; think that the product is marked on the product, and the mobile power supply is marked on the package and the manual. Some products that pursue a simple style will also mark as little content as possible on the outer casing, resulting in The information is not comprehensive. Through the previous analysis, it can be found that all the 60 mobile power monitoring failures are caused by many reasons. Of course, the mobile power manufacturers themselves are the first problem. Since there is no standard specification for a long time, the development direction of mobile power is also varied. Many manufacturers have made great differences in order to cater to the user's preference. Fortunately, the quality of the brand mobile power supply has a good guarantee. The unqualified part is that the appearance and the capacity label on the package are not comprehensive. This is very easy to change. As long as you unify the specifications, you can enter the market. Monitoring mobile power with low conversion efficiency. On the other hand, the development of mobile power standards is also biased. In some details, it is not considered to match the actual needs of users. In the trend of digital products to a simple appearance, devices such as mobile phones and tablets minimize the externally labeled information to make the product simple and beautiful. For mobile power, it is necessary to label too much content without considering the user and Market demand. Of course, this is only the author's personal point of view, and the development of mobile power standards is also well thought out. There is still room for improvement in mobile power. In addition, some media have highlighted all the unqualified conclusions in order to cater to the user's curiosity. They have not analyzed the real situation behind them, and have made more users feel that mobile power is “not reliable”. In general, the problem of product quality caused by the non-standardization of the mobile power market does exist, but far from being completely exaggerated in the news reports, the development of the industry must not only have the consciousness of the manufacturers and the norms of the market, but consumers should also understand some The basic knowledge of the product, so that when you purchase the product, you will not be promoted to take the nose, so you can choose a mobile power that is more suitable for you.
