The Ministry of Industry and Information Technology stipulates that the power of wireless fast charge must be less than 50 watts, and why do you have such a requirement is not clear, but what you know is the limit, the power of this charge is not because of radiation,Because radiation is everywhere, all the time, not all radiation will affect the human body.
The regulation requires that from January 1, 2022, the rated transmission power of mobile and portable wireless charging devices is required to be no more than 50W. Although it is only a draft for comments, there is news that the 50W wireless fast charge cap policy has begun to be implemented.
Comparing the domestic and foreign mobile phones collected in 2023, it can be easily found that overseas brand mobile phones are inferior to most domestic mobile phone brands in terms of charging type range and wireless charging rate, and the wireless charging peak value of 50WIt is enough to make overseas brand mobile phones difficult to look back.
For example, the 80W Sailing wireless charger requires 20V PPS/MiPPS protocol to activate the fast charge above 30W, while the Xiaomi 50W vertical charger Pro requires a specific charger above 67W to play its full potential. Redmi 30W wireless charger has higher requirements, and specific activation conditions may vary. The Xiaomi 20W vertical requires the use of a QC 0 Class B protocol charger to ensure the best charging effect.

3, CE certification standards are prepared by experts of EU member states. Certified by three European standardization organizations, CEN, CENELEC or ETSI standards, it has been recognized as a voluntary technical standard document that complies with EU standards. This standard specifies the procedures that must be followed for CE certification in order for the relevant products to comply with the requirements of the European CE Directive. The EN standard has been accepted by all European member States. Most of the standards are based on industrial needs.
4, do CE certification, provide samples, instructions can be, Aido test certification, handlingCE, fast, discount.
5, CE certification certification agency: the application for CE certification can be issued by a foreign NB announcement number agency or a third-party testing agency.
Legal analysis: The formulation of the standard is to regulate the use of wireless charging equipment New wireless charging regulations to avoid harmful interference to all kinds of radio services carried out in accordance with the law, and maintain the order of air waves.Radio is a public resource, just like road resources, it needs to be used rationally and cannot interfere with others, and it is the same for low-power wireless charging.
Because there are now relevant policies to limit the power of wireless charging, although it is in the stage of soliciting opinions, but it may also affect the planning of the later manufacturers, the highest wireless charging rated power is 50W. And Xiaomi's 120W has not yet been mass produced and has been criticized, feeling very aggrieved. After all, the policy has not yet been implemented, and it is too early to speak.
Recently, the Ministry of Industry and Information Technology issued the "Wireless charging (Power transmission) equipment radio Management Interim Provisions (draft for comments)", the interim provisions clearly indicated that the rated transmission power requirements of wireless charging is less than 50W. This is to prevent wireless devices from interfering with each other.
High-power wireless charging devices are prohibited mainly because they interfere too much with wireless signals. At present, wireless charging technology is very mature and stable, and there is no problem in security, but due to the amplification of power, it will bring some unexpected troubles to production and consumption in terms of signal interference.
If wireless charging is at night, the situation of limited power is normal, which is a point that Huawei considers specifically for users. After all, when we charge at night, we will charge all night, so there will be some damage to the battery.
1, some time ago wireless charging new regulations , smallM released wireless charging new regulations their own space charging technology wireless charging new regulations , the power is 5W wireless charging new regulations , From millet promotional video can be seen wireless charging new regulations , such technology is indeed very science fiction, but may not be able to use in the country. Just today, the Ministry of Industry and Information Technology in the "Wireless charging (Power transmission) equipment radio Management Interim Provisions (draft for comments)" in the fourth, mobile and portable wirelessThe rated transmission power of the charging device shall not exceed 50W.
2, according to Lei Jun, soon, millet self-developed air separation charging can also be used for smart watches, bracelets and other wearable devices. In the future, the living room, including small smart home products such as speakers and lamps, can realize wireless power supply design, get rid of the cord bondage, and truly realize the wireless living room. For now, Xiaomi's first self-developed air separation charging system has a long way to go, and it has not yet been mass-produced. 3, so in January 2021, Xiaomi released the air charging technology, as Lei Jun, president of Xiaomi, said on the official micro: air chargingElectrical technology is like a science fiction movie, holding a mobile phone into the living room, you can achieve air charging. The air charging launched by millet has several advantages, which solves the pain points of air charging. For example, support for multiple devices charging at the same time, which means that a charger at home to meet the charging needs of several mobile phones.
4, millet officially released the space charging technology, the science and technology digital industry ushered in a new breakthrough Millet CEO Lei Jun revealed on the personal public number that millet has successfully developed and launched the space charging technology, the technology can be realized on millet 11. The biggest highlight of this technology is its amazing effective distance of several meters, even when objects are hiddenStop, can also maintain stable charging, to achieve true wireless charging freedom.
