by John Xu Consultant
As a phone charger necessary ancillary products how to buy, many people are still poorly understood. Reporters visited the market found before a unified national cell phone charger, a seemingly convenient and inexpensive "universal mobile phone charger" has become many people's choice. However, these handy behind, and the number of hidden security risks it?

Complaint "universal" charger with two scrapped

Paving Mr. Lin, who lives in a mobile phone repair shop recently bought a not marked with the manufacturer's "universal charger" for the first time using the normal, can second use out of the question, plug in the power less than ten minutes, I heard "bang", followed by white smoke emerging charger, battery also "fly" up, scrap can not be used. The next day, he found the cell phone repair shop, the owner denied selling over which the charger. In desperation, he had complained to the business sector. Patient mediation by law enforcement officers, the phone owner was finally admitted that the phone charger is sold, and agreed to compensate the loss of Mr. Lin.

Reporters learned yesterday from the city center 12315, this year, the city's industrial and commercial department has received hundreds of complaints from mobile phone chargers consulting, focused on the charger is not charging properly, fever, charging explosion, businesses do not fulfill the obligations of three bags, etc. .

Investigation "universal charge" many brands cost less than 10 yuan

Yesterday, the reporter visited the river head of Taiwan Street, Xianyue road, after the lake pond along the mobile phone retailers found that "universal charge" almost

This charger look roughly the same, there are about a dozen brands, with an average price of only about 7 yuan, the lowest 5 yuan a store willing to sell it. These universal charger 3C no more signs, similar structure, external mainly plastic texture, plywood on the front with two metal contacts, no matter what size, what shape of mobile phone batteries, just use the "universal charge" the battery plywood grip, and let the metal contacts on the battery metal contacts on the clip in close contact, through the power line.

The reporter found in Guangdong Province, Trade and Industry Bureau recently released the circulation of mobile phone batteries, chargers sampling, four indicators of failure of "Scud" Travel Charger (Model SC537A + 220V ~ 50Hz≤100mA), in the city of some small communications equipment shop still selling.

Saying "universal charge" only for emergency needs

According to businessmen, the "universal charge" The biggest feature is very fast charging with original charger battery needs to be charged for two hours, it takes only about one hour. However, this low price, simple structure "universal charge" really reassuring to use it? Quality supervision departments of the experts said in an interview, choose universal charger, only for emergency needs.

According to experts, original mobile phone charger has over-voltage protection circuit, output voltage can be maintained at about 3.6 volts, and is equipped with a transformer rectifier unit, you can make high-voltage transformer low voltage, direct current into alternating current. The universal charger manufacturers mostly informal, without protective coil in the charger, easily the voltage or current is too high, though you can instantly complete the charge, but in fact the battery does not really full, and soon electricity will run out; because no protection circuit, the high voltage is also easy to charge the battery pack drum, sometimes resulting in the risk of explosion, the phone can easily be burned. It is recommended that consumers be better to use the regular brand or original charger. Battery wick steel, aluminum and plastic film, steel and aluminum are relatively cheap. Such as a battery with a steel core, explosive, powerful. Prior to Jiang's battery is blind bombing steel cell battery.

18th of this month, members of the public Mr. Jiang with 13 yuan to buy a cell phone battery exploded while charging, causing the left eyeball was burst. Reporter survey found that mobile phone battery price far cry from two dozen to a hundred dollars there. Insiders pointed out that a twenty dollar "no-name battery" estimate accounted for eighty percent share of the market, due to the often taken as an inexpensive steel core battery cells, easier to explosion, the power is greater.

Modify the battery 5 minutes fixed up

Reporters interviewed found that mobile phone battery price falls far short of the big brand original battery frequently one or two hundred dollars, but in the electronic communications market of brand-name battery, but only twenty dollars, in the mid-priced brand batteries will have about 50 yuan. Zhongshan Road in Amoy Street electrical city, the reporter saw stalls played "scene change the batteries, extraordinary stand for 3 to 7 days" signs. I ran into an already bloated public holding cell asked if he could repair. "I can," the clerk answered as close to the outside of the battery sticker ripped out the inside of the battery cell, took out a new battery cell from under the counter, and then carefully put the battery cell and battery protection plate welding, then use voltage testing, see the voltage to "3.7V" after they readily took out a printed "NOKIA" word wrap sticker battery again, the whole process less than five minutes, for the core costs 15 yuan.

Plastic film battery safer housing

Do cell production in Shenzhen ten years Mr. Wang said, if you want to completely regular production of batteries, costs generally 15 to 20 yuan, the retail price will certainly be more than 30 yuan, so a twenty dollar cheap battery definitely cut corners, use poor quality battery cells.

"Battery wick steel, aluminum and plastic film, steel and aluminum is cheaper." Mr. Wang said, the highest strength steel is also the most dangerous, because the steel is not easily deformed, reaching expansion and deformation, has accumulated inside a lot of gas, once burst up on the great power, "the same as the shell." The fried blind Jiang battery is steel battery. Now some big brand manufacturers use plastic film battery housing, relatively a lot of security, but steel is more expensive than the cost of two percent, accounting for a market share of less than Chengdu.

Modify the battery like a grenade

A battery manufacturer said modified cell phone battery is very dangerous, because after being modified voltage characteristics of the battery is changed, resulting in the collection of electricity appears to be incorrect, could cause cooling problems together after modification, an important reason for this is the explosion.

Quality supervision departments to remind: the first time when the new battery charge can touch the shell temperature is too high, generally the initial battery charge (within 1 hour) will generate heat, but the temperature is not too high; aft
freeblog-batterieakkuer the temperature close to ambient temperature; if the charge after one hour The battery case temperature is high (hot), it is possible to charge the battery protection circuit problem, for safety reasons, they should stop using it. Also, do not frequent recharging, avoid prolonged charging, can be filled. If the battery is accidentally been dropped or heavy impact too, do not rush to charge, be sure to check the battery casing for cracks, pay attention to the battery charging case temperature is abnormal, so as not to cause damage to the internal protection circuit accidents.
