The cottage mobile phone charger frequently hurts people

Not long ago, an airline stewardess was charged and her mobile phone charger was not original. The cottage charger became the biggest suspect. When this matter was heatedly discussed, when it had not yet subsided, there have been several accidents that have caused injuries due to the use of low-quality chargers.

"Ever more than forty days, my son still didn't wake up. I was really scared that my eldest son 'slept' in the past..." Yesterday, Dong Yayun's left hand, his son Wu Jiantong, was lying in his bed and his tears kept flowing.

Wu Jiantong, 30, is a brother of Changchun. On July 6th, he went to visit his parents working in Beijing. On the evening of July 8th, he was stunned by an electric shock while charging the iPhone 4, and he still did not wake up.

Wu Jiantong is a brother of Changchun. His parents and sister work in Beijing. They have not met for more than a year. On July 6, Wu Jiantong went to Beijing to visit his parents and sister. At 22 o'clock on the 8th of July, when he was busy playing iPhone 4 mobile games, he had no power to turn off his mobile phone, and he stood up and charged the phone.

Dong Yayun recalls that his son first inserted the charger into the socket and then plugged in the charging socket of the mobile phone. “Suddenly, he shouted, 'Stuck live', and then fell to the ground. His sister Wu Jianxiang turned her back to him at that time. After running to the ground, he immediately ran to his brother and found that his brother still held the line and cell phone of the charger. When his son got an electric shock, his body twitched, and his lips and face turned green instantly, spitting white foam from his mouth, said Dong Yayun.

When Wu Jiantong was sent to the hospital, the situation was very bad. There was no spontaneous breathing. Although the heart rate had recovered, it reached 160 times per minute. The time of hypoxia was longer and the brain was seriously damaged.

After three days of rescue, Wu Jiantong’s indicators were relatively stable. On July 15, Wu Jiantong resumed spontaneous breathing, but his brain has not recovered consciousness and is still in a coma.

Dong Yayun said that his son is using a white iPhone 4 phone. After the incident, the phone is not the same, but it can not boot, the charger and charger cable to connect the phone looks intact. After his son got a coma, he got the attention of several media in Beijing and other cities. The reporter once sought the relevant departments to identify his mobile phone and charger. As a result, the son's mobile phone charger was not original, but was a knockoff cargo. Some time ago the mobile phone charger was lost. The charger for the incident was allocated by him. “Experts say that when the son was charging his mobile phone, he would probably not convert the 220V voltage because of the cottage charger, but sent it directly to the mobile phone, causing her son to be electrocuted,” she said.

Mr. Wang, a mobile phone repairman in Changchun, said that the quality of the mobile phone charger and the original mobile phone charger in the cottage are very different in quality. The internal design of the circuit is not the same. The protective measures in the current protection are also strong and weak. When the mobile phone is charged, the mobile phone charger under normal operation will reduce the voltage of 220V to about 5V. This voltage is far lower than the human body can withstand 36V. Even if the casing of the mobile phone is leaked, it will not cause electric shock. However, when using the cottage charger, the circuit safety protection is prone to problems, and it is possible to directly transmit the voltage of 220V to the mobile phone, resulting in the electric shock.

Cottage charger burst

Mr. Gao bought an Apple cottage two years ago. The mobile phone could not be used any longer, but the charger has not been thrown. Yesterday, Mr. Gao took the charger and charged the phone. “I heard a bang and looked back and saw a black smoke.” At that time, the house was full of charred smell. Look closely and connect the charger's wiring board. There was a fissure about 1 centimeter long, with many burnt blacks inside. "Too scary, you can't really use the cottage charger next time. If you just called at the time, you don't know what will happen," said Mr. Gao, with regret.

Consumer Association released inferior charger can cause death
Not long ago, the China Consumers Association issued an early warning that in the northeastern region, there was a malignant case of death due to electrocution when a consumer used a charger that had not been certified by CCC security when he was answering a call. A survey by the reporter found that there are many universal power adapters including mobile phone chargers that are not certified by the CCC. Most of the safety indicators are unqualified, which may cause users to face electric shock, fire, and burns.

Inclusion of mandatory CCC catalog

The reporter learned that the AQSIQ and the National Certification and Accreditation Administration issued the announcement of the “Product Catalog for the First Batch of Compulsory Product Certifications” in 2001. After several adjustments, the current CCC compulsory certification catalog contains two types of power adapter products: Audio and video equipment supporting power adapter (including charge / discharge device); computer built-in power supply and power adapter, charger (power adapter for information technology equipment).

However, it is also mentioned in the mandatory catalogue that the power adapter (charger) for telecommunication terminal products should be tested with the whole machine and not in the scope of CCC certification. In this regard, the relevant person in charge of the CNCA explained that the mobile phone charger performs the whole-machine CCC test with the mobile phone, so it is no longer solely responsible for CCC certification. Separately produced mobile phone chargers have not been included in the mandatory certification list. For the safety of this part of the charger, the industry has already called for the “introducing separately produced chargers into the mandatory certification catalogue”. The CNCA also suggests that consumers should purchase a power adapter with the CCC logo. The CCC-certified power adapter meets the national mandatory standards for electrical safety and electromagnetic compatibility performance. The safety is guaranteed, and the CCC logo is true and false. You can visit the website of the CNCA.
