Variety, dazzling mobile phone charger is moving toward reunification. Last week, the European Telecommunications Commission announced with Nokia, Motorola, Samsung, Apple and other top ten leading mobile phone manufacturers have signed a Memorandum of Understanding from 2010 onwards in the whole EU-wide uniform standard mobile phone charger. Before 2007, the Chinese market has been in the former Ministry of Information Industry of the "match" to complete the cell phone charger harmonization of standards, coupled with earlier South Korea, and Japan, mobile phone charger harmonization of standards has become a trend.
It is worth noting that the EU adopt a uniform standard charger and charger developed by Chinese standards, while not entirely consistent, but fortunately, is compatible between the two. Industry expects a unified standard mobile phone charger on a global scale will be further evolution, the future may be unified micro (Micro) USB interface. The domestic manufacturers are also being gradually abandoned the current small (Mini) USB interface, to the more common mini-USB interface to move closer.
China, EU standards compatible
According to information released by EU Telecommunications Commission, 2010, signed a Memorandum of Understanding of 10 mobile phone manufacturers will adopt a unified micro-USB interface. This is a way to support both charging and data transfer capabilities of the new USB interface, its biggest feature is the small, light and thin can the demand for mobile phones.
According to Reporters learned that China is a unified standard mobile phone charger is used "power adapter + data charging cable" free configuration, the main power adapter is mandatory end of the specification. China's standard, power adapter must have a USB output port, but the charging / data lines are connected to allow different manufacturers use different end of the line mobile phone standard. To Nokia, for example, the world's largest mobile phone manufacturers to use is the charge separation line and data line design, mobile phone charging cable that one end of the port mainly small round mouth with exclusive design, but the data line is already full use of micro- USB interface. However, according to Nokia's PR people, at present in the new release of Nokia's models have begun to gradually adopt charging, data combo design, micro-USB interface in the future will become the only option.
Motorola China also told reporters about the company's mobile phone from a year ago began charging universal access, data transmission combo micro USB interface, the future even if the user is in the country to buy the phone, certainly to the EU Roaming can use, not to replace the charger. The source also said the current situation, although the end of the domestic mobile phone charging port are different, but because of the power adapter has been unified, using a standard USB interface output, even if consumers switch to the future of the EU standard mobile phones, it will not encounter compatibility problems, "when the time is up for a mini-USB interface with charging lines on it, do not replace the charger."
Will become the global standard mini-USB interface
And the European Commission signed in the top ten mobile phone manufacturers, Nokia, Motorola, Samsung, LG and other manufacturers in the Chinese market has begun to use micro-USB interface, mobile phones, for a global standard to reduce the cost considerations, the future of these companies will be further promote micro-USB interface, mobile phones sold in the domestic and the EU will be started simultaneously mini-USB interface. At present, Sony Ericsson still insist on using their own interface standards, the Chinese companies concerned told reporters that the memorandum of understanding reached in the European Union, the company's charging, data transfer interface has been replaced, "ready to launch this year the interface of several smart phones have begun to turn into a mini-USB interface. " According to the sources, the next two to three years, Sony Ericsson's line of products will use micro-USB interface.
Not only that, because Qualcomm, TI and other upstream companies for their support in a number of future 3G mobile phones, mini-USB port is destined to become the mainstream standard. According to the Shenzhen Yulong Cool introduces its new telecom CDMA standard 3G phones have been changed to use the mini-USB.
According to reporter understood that more than 80% of the domestic mobile phone handsets are the use of small (Mini) USB interface, this highly popular and MTK program has a great relationship, on the other hand it is because of cost considerations. However, with the opening of the domestic 3G market, coupled with the prevalence of ultra-slim handset, the current Sky, Hisense, Lenovo and other mobile phone manufacturers have begun in some high-end smart phones to use mini-USB interface. "Now the cost of the two interfaces have almost the same, but now many of CDMA and WCDMA mobile phones using Qualcomm's solution, using a micro-USB interface is also more convenient." Yulong Coolpad who told reporters. In his view, the future of most of the domestic mobile phone also will be unified to the mini-USB port, because in order to make cost-optimized.
