The status of mobile power: fraud, cutting corners

Since the high-speed development of the smart phone market, various peripheral accessories industries have also become very popular, the most typical of which is a mobile power (commonly known as "charging treasure"). In recent years, smart phones have become more and more functional, and people are using more and more frequently. Inevitably, the power consumption of mobile phones is getting faster and faster, and many mobile phones even have less than one day of standby time. As a result, charging Po almost became a necessity for the staff.

However, due to the fact that the country does not have a rigid standard for mobile power sources, a large amount of capital is flowing into the field, and the price war has caused the quality of mobile power sources to be uneven. Especially since last year, news about the short-circuit explosion of mobile power has been frequently reported. You may think that the explosion is only a small probability and may not happen to you. In fact, it is only one of the extreme evils of mobile power. In addition, various issues that you can't see are becoming increasingly fiercer with capacity falsification, falsification gain, shoddy, and fake. Nandu reporters field surveys to reveal the truth about the mobile power market.

Lithium battery batteries do not work? There are no hard regulations in the country

Recently, the reader, Mr. Li, reported to Southern Reporter that he had purchased a mobile power supply with a brand name of “Winning Cookie”. "I accidentally fell to the ground and the shell cracked and revealed the inside part. I found that the power supply inside was just a cell phone lithium battery." According to the picture provided by Mr. Li, the intelligence on the battery is clearly marked as "Winning". Cell phone battery, with a capacity of 1340 mAh. "Is this a mobile power source made from a waste cell phone battery? Is there any security risk?" Mr. Li raised his own doubts.

With problems, the reporter from Nandu contacted Zhong Guanghua, deputy general manager of Pinsheng. He told reporters that the charging cookie is a low-cost mobile power source. It is indeed a mobile phone battery used as a battery core, but it is not a waste product. This point is clearly written on the official Weibo.

Immediately afterwards, Nandu reporters found relevant content on the official Weibo website. On April 25th, Pinsheng had released a microblogging commentary that the “charging cookie” was positioned as an emergency charging product and was characterized by light weight. “Pinsheng, as a mobile phone battery manufacturer, will generate a large amount of battery inventory when the organic type (refers to the mobile phone) is down or miscalculated.” Pinsheng said that we classify the batteries in terms of volume and capacity. And each battery is tested to confirm that the battery meets the electrical requirements of the cookie cutter, and the battery that passes the test will become the core of the charging cookie.

Product wins also emphasized that since the lithium battery models are different, the capacity of the charging cookie is not a fixed value, but it is guaranteed to use a brand new mobile phone lithium battery. According to this statement, it is not used batteries that are used to charge cookies, but it is definitely an inventory lithium battery product. So Mr. Li has a new question. Is this legal and compliant?

According to the information reviewed by Southern Reporters, at present there are no mandatory standards for mobile power in China. In other words, there is no violation in the practice of goods wins. The key is whether consumers accept it or not. However, it is precisely because of irregularities, the current mobile power industry is more dependent on the self-discipline of the manufacturer.

Void increase odds and hundreds of bad mobile power hidden serious

Through the mobile power industry channel, Nandu reporter obtained a "USB interface class mobile power test standard" (proposed by the China Chemical and Physical Power Supply Industry Association, not a national standard), the content shows that the standard by Xin Wang Electronics Co., Ltd. The drafting of the organization was completed by the standards writing working group, among which are the domestic famous mobile power and battery manufacturers such as Pinson Electronics, Wantuo Electronics, Desai Battery, Bestek, Shenzhen Chuangming and Sichuan Changhong.

Li Fugen, sales director of Wantuo Electronics, said in an interview with Nandu reporters that the introduction of the standard is a great role in requiring companies to participate in self-discipline to ensure the safety and reliability of mobile power products and supply chains. However, this is not a national standard after all. Under increasingly fierce market competition, there is no objective constraint, and today's mobile power market is indeed evil.

Li Fugen introduced several kinds of tricks that are common in mobile power products. The first is the virtual standard. "A mobile power source marked with 10000 mA may not be able to meet the standard at all." He said that when users use mobile power, they rarely care about their mobile phone lithium battery capacity, 10000 mA in the end can charge a few The second power, which gave Black Heart's mobile power producers a hole.

The second problem that derives from this is "give weight gain." He also took a mobile power source of 10000 milliamps as an example. Assume that a 4,000 mAh mobile power source requires four 2500 mAh battery packs. The manufacturer may only have three or even two batteries. In order to ensure the weight of the product, it often puts waste batteries, iron blocks and even cement blocks inside to gain weight. Due to the lack of telecommunications, this product is certainly not up to standard capacity.

If the above two kinds of tricks are only fraudulent, "shrinkage" is hidden a great security risk. According to Li Fugen, many small factories now use used batteries as batteries for mobile power sources. Many of these batteries were removed from old phones, and some were even foreign garbage. Adding inferior circuit boards without overload protection, even for cost savings, can be problematic without the use of a single capacitor as the controller. "These batteries may have been bulging or leaking, and short circuit explosions are possible."

The growing market demand has attracted a large number of companies to enter the competition, and there is no national mandatory standards to restrain them. With the word of benefit, the field of mobile power is becoming less and less bottom line.

The capacity does not match the price to decrypt the rigid cost of mobile power

A component supplier analyzed the hardware cost structure of the mobile power supply to the South Reporter --- A mobile power supply consists of a shell, a U SB interface, a circuit board, and a battery. Among them, batteries account for more than 70% of the cost, and 20% are part of the circuit board. At present, the best battery in the industry is represented by Samsung. The price of a 2000 mAh battery is over 20 yuan. If it is used to make 10000 mA of mobile power, the cost of the photoelectric core will be more than 100 yuan. Followed by domestic (including joint venture) brand of first-class batteries, the price must be more than ten dollars. As long as you cut corners on the above, you can squeeze a lot of profits. Plus the circuit board is also a great difference between good and bad, and can squeeze out some profits.

Search for 10000 mAh mobile power on Taobao. You will find a large number of products with a price below $50, and the sales volume is very high. The person said that even with the worst battery, it is impossible to create a mobile power supply of 10,000 mA below 50 yuan, and the result must be a virtual standard capacity and cutting corners.

It is worth noting that in many 3C products, brands can bring premium effects to products. For example, if you configure the same mobile phone, Samsung mobile phones can sell at a higher price than ZTE mobile phones. However, according to Li Fugen, this point is not applicable in the mobile power market. He admitted that Wantuo has been involved in this field since 2004 and has launched the first mobile power supply. However, in the rapid development of the entire market, Wantuo focused on the sales side and did not consider branding and accumulation. So far, in order to ensure the quality of products, it is impossible to pull prices down, and a large number of markets are swallowed up by small brands. "This is not only a problem for Wantuo, but also a problem that many mobile power plants are facing."

Interestingly, because of the lack of brand in the mobile power market, millet's power supply launched last year by Xiaomi Company was very successful, so the small factories also saw the power of the brand. However, they did not choose the normal brand value-added road, but they thought of counterfeiting this "shortcut."

In April of this year, Hong Kong netizens reported that the power supply of the millet they had purchased exploded. After identification, this is a fake and shoddy product. Recently, the two police in Guangzhou and Shenzhen successfully dismantled two special-sized rice power dens named “Shenzhen Hongjing Electronics Factory” and “Guangzhou Yuesheng Electronics Factory”, and seized over 3,000 copies of millet mobile power. There are about 15,000 headsets. At present, the heads of the two counterfeit companies have been taken away by the police. When interviewed by Southern Metropolis reporters, relevant people of Xiaomi said that at present, millet power is only sold in the official website of Xiaomi and a few special dealers, and its products with channels are almost all counterfeit.
