What Is a Universal Charger?

The universal mobile phone charger standard was promulgated on November 14, 2006, and it was formally implemented and enforced from June 14, 2007. The standard stipulates that the universal charger will take the form of a USB data cable and a female charger with a USB port to solve the incompatibility of mobile phone chargers for many years. On October 23, 2009, according to the United Nations website, as part of efforts to mitigate climate change, the International Telecommunication Union announced on October 22 that it had approved a solution for energy-saving universal chargers for mobile phones. This solution will enable all future phones to use the same charger regardless of their production and model.

Mobile phone universal charger standard

The material saved through the standard of mobile phone universal charger can save 2 billion yuan per year. As of June 2007, 15 types of unified interface mobile phone chargers produced by 14 companies across the country have obtained products

A survey by Guangzhou Daily showed that the Ministry of Information Industry will carry out a survey on the communication industry standards of "Mobile Phone Handset Charger and Interface Technical Requirements and Test Methods" (YD / T1591-2006) in the mobile phone network access inspection. None of the readers surveyed opposed the measure. Specific to the survey data, 71.47% of the readers surveyed said that the standard will solve the incompatibility of mobile phone chargers that have long plagued consumers. 16.76% of readers think that in this way, you can spend less money when changing phones. This shows that nearly 90% of the surveyed readers welcome the standard. From the reader's feedback, the main reason for implementing this standard is to solve compatibility problems without wasting and environmental protection. The reader "zyc" believes that the data cable interface and the headphone interface should be unified, so that different interfaces must have different cables, which is too much trouble to carry. On the other hand, 11.77% of the readers surveyed chose "other", indicating that they were not clear about the actual situation after the implementation of the standard.

On October 23, 2009, the International Telecommunication Union stated that it had approved a solution for energy-saving universal chargers for mobile phones. In addition to significantly reducing the number of chargers produced, shipped, and subsequently discarded due to new models, the new standard will mean that users around the world can charge mobile phones anywhere and with any available charger, and reduce charging time Energy consumption. Implementing the new standard can reduce standby energy consumption by 50%, reduce excess chargers by 51,000 tons per year, and thereby reduce greenhouse gas emissions by 13.6 million tons. According to ITU, this is an important step in reducing the environmental impact of mobile phone charging, while also making mobile phones easier to use. ITU hopes to see practical solutions in other areas as well, such as the provision of universal chargers.

ITU will participate in the next round of climate change negotiations, held in Barcelona from November 2 to 6, 2009, to emphasize the importance of information and communication technology as the main tool for reducing greenhouse gas emissions across industries. A recent study predicts that the more effective use of today's information and communication technologies is expected to reduce global emissions by 15% by 2020, and that carbon savings will be five times higher than the projected emissions for the entire ICT industry in 2020.
