High capacity battery charging should be vigilant

"South flight attendant suspected that the use of rechargeable iphone was electrocuted death," a new development. CCTV broadcast yesterday's news footage showed that the deceased's mobile phone is iPhone4, not metal shell IPhone5, the phone on both sides of the obvious burning traces, mobile phone charger not Apple mainland original charger. Yesterday, Apple didn't have a new stance.

According to CCTV reports, the police found in the scene, the deceased body is a lot of electric shock burns, the side of the IPhone4 mobile phone is charging, but the mobile phone data lines, chargers and strips are intact, the mobile phone can also normal boot. There are obvious burns on both sides of the phone.

CCTV said the death of the deceased was a mobile phone problem, police are being identified. But as of yesterday's press, the police still did not release further investigation results, Apple also did not further comment.

The reporter noted that from the CCTV broadcast screen, the deceased used the charger is not Apple's original iphone phone charger.

Telecommunications expert Xiang said that from the current situation, it is possible that the problem of Shanzhai charger. "The Shanzhai charger has the potential to cut corners, the quality of the capacitor, the protection circuit does not do well, resulting in the charger capacitor breakdown, 220V of alternating current directly into the cell phone battery." ”

Apple hasn't got a new stance.

"But there is one possibility. We know that Hong Kong and Taiwan, Japan with 110V voltage, the Chinese mainland with 220V. If the charger is done according to the 110V voltage, its capacity to hold the voltage will be relatively weak. There may be a breakdown of the situation. "Xiang said.

According to the hand-machine manufacturers, mobile phone charging, the charger will reduce the voltage of 220V to about 5V. And this voltage is far lower than the human body can withstand 36V, so even if the phone leakage, it will not cause people to be electrocuted. If the charger fails, or the circuit security problems, the charging process of the charger does have the potential to transfer the voltage of 220V directly to the cell phone battery, causing the human body to be electrocuted.

Xiang think, to cause people to die also need a prerequisite, is the mobile phone also have problems, the current directly to the phone shell. "But in this case, the mobile phone is not still normal use." CCTV reports show that the deceased's iPhone4 cell phone can still be turned on properly.

"We are deeply saddened by this unfortunate incident and express our deepest condolences to the bereaved family," Apple said in a statement on July 14. We will conduct a thorough investigation into this matter and provide the relevant bodies with full cooperation. ”

Apple didn't have a new stance on the matter yesterday.

High capacity battery charging should be vigilant

Earlier, the media also disclosed the explosion of mobile phones, causing the use of human face destroyed cases. Insiders say more than 3000 MA batteries are a bomb.

Experts say cell phone battery explosions can occur because of a short battery. Its explosion destructive at most is burning, instantaneous exothermic causes the user skin to injure. If the phone is attached to the charger, it does not rule out the possibility of death by electricity. But this probability is very small, normal mobile phone will have protection mechanism.

In addition, now the mobile screen is more and more, the power consumption is soaring, so the cell phone battery capacity is also increasing, even some mobile phone with 5000 ma battery.

Experts also recommend users, buy chargers, mobile phones, to choose a big brand, quality is guaranteed. Second, try to avoid using in high temperature environment. When a cell phone is charged, it should be placed in a place where it is easy to dissipate heat. Third, try to avoid charging when the phone call, the possibility of the accident is very small, but to nip in the bud. Four, avoid impact, collision mobile phone.
