Hello, vivoy77 original charging head is generally about 100 yuan, you can go to vivo official website to buy, I hope my answer can help you.
Y77 adoptedType-C charging interface (supports OTG function).
How much w does vivoY77 charge? vivoY77 charging power of 80W, equipped with 4500mAh battery, 15 minutes from 0 to 61% charge, half an hour can be the entire phone full. In the image system area, vivo Y77 uses a large cloud level double mirror design with a circle in the square, and the cloud level double mirror interior is also through star color internal plating and star diamond lithography 0 technology, bringing a colorful and changeable fashion luster, which looks quite recognizable.
Y77 headphone port is 5mm US standard, outIs the new standard EN62368-1'>EN60950 outdated? Is the new standard EN62368-1 already used?
1, IEC/EN62368-1 is the latest international product safety standard, which covers audiovisual, consumer electronics, consulting technology products, It will completely replace the existing IEC 60950-1 and IEC 60065 standards in the next few years (currently the EU is expected to replace the old 60950 and 60065 standards on December 20, 2020).
2, from December 2020From the 20th EN 62368 will replace the previous standard, and after this date EN60950-1 and EN60065 cannot be used to indicate compliance with the low energy standard.
3, Note: According to the EU CE mark for the "placed on the market" time, as long as the product enters the market must comply with the regulations, indicating that the product will not be able to enter the EU market in accordance with EN 60950-1 and EN 60065 standards from December 20, 2020.
4, the IEC standard itself is voluntary, there is no mandatory implementation requirements.
5, IEC 62368-1 will replace IEC 60950 and IEC 60065 for a transition period of 5 years. At present, the standard for compulsory 3C certification of audio and video, information technology and communication technology equipment in China is the national standard GB 4941 and GB 8898 corresponding to IEC 60950 and IEC 60065. Therefore, the development of IEC 62368-1 is actually a vane for the development of China's 3C compulsory certification standards GB 4941 and GB 8898.
2, wireless MikeWind CE-RED certification Test Standard for Electrical Safety (LVD) : EN 62368-1:2014 A11:2017. Electromagnetic Compatibility (EMC) : EN 301489-1 V3 (general), EN 301489-17 V0 (Bluetooth, WALN). Radio frequency (RF) : EN 300328 V2. Health (SAR) : EN 62479:2010 (or EN 50663:201 less than 20mW can be detected).
3, as we all know, the safety management concept of electronic products is experiencing epoch-makingEspecially for IT products, audio and video products and communication equipment, the introduction of the new standard UL/EN/IEC 62368-1 will replace the existing UL/EN/IEC 60950-1 (Information technology IET standard) and UL/EN/IEC60065-1 (audio and video AV standard).
1. IEC 62368-1 will replace IECThe transition period for 60950 and IEC 60065 is 5 years. At present, the standard for compulsory 3C certification of audio and video, information technology and communication technology equipment in China is the national standard GB 4941 and GB 8898 corresponding to IEC 60950 and IEC 60065. Therefore, the development of IEC 62368-1 is actually a vane for the development of China's 3C compulsory certification standards GB 4941 and GB 8898.
2. To this end, IEC set out to develop a new security standard for audio, video, information and communication equipment to replace the existing electronics industry influenceThe two largest standards - audio, video and Rais electronic equipment safety standard IEC60065 and information technology equipment safety standard IEC60950-1, the International Electrotechnical Commission after 8 years, in January 21, 2010 published IEC62368-1 "Audio/video, information and communication equipment Part 1: Safety Requirements (1st edition) Standard.
3, IEC TR62368-2 (Version 0), expected to be released in June 2019. 62368-1 (Version 0) Mandatory implementation date IEC 62368-1 (version 0)The IEC standards themselves are voluntary and have no mandatory requirements.
4, IEC62368 is the CB test certification of information products. Safety type approval applications in most countries and regions can accept both IEC 62368-1 (2nd / 3rd edition) and IEC 60950-1/IEC 60065 standards. However, some countries and regions have not officially issued or implemented their own national or regional standards corresponding to IEC 62368-1, and their safety type approval applications can only accept IEC 60950-1/IEC 60065 standard.
5, IEC 62368-1 is the latest international product safety standard, covering audio-visual, consumer electronics, information technology products; It will replace the existing IEC 60950-1 and IEC 60065 in the next few years. The authority of IEC standards is recognized throughout the world. IEC holds more than 100 international standards conferences around the world every year, and nearly 100,000 experts from all over the world participate in the formulation and revision of IEC standards.
6, IEC/EN62368-1 is the latest international product safety standard, it coversAudiovisual, consumer electronics and consulting technology products will completely replace the current IEC 60950-1 and IEC 60065 standards in the next few years (currently the EU is expected to replace the old 60950 and 60065 standards on December 20, 2020).
2, IEC 62368: Integration and impact IEC 62368 is the International Electrotechnical Commission's careful integration of IT IEC 60950 and audio and video IEC 60065 standards, designed to provide a unified safety specification for audio and video and information technology equipment. It stems from the broad similarity between the two standards, allowingThe products meet both IT and audio and video testing requirements, thus simplifying the entry criteria for international markets.
3, to this end, the IEC began to develop a new audio and video, information and communication equipment safety standards, to replace the current electronics industry's two most influential standards - audio, video and Rais electronic equipment safety standard IEC60065 and information technology equipment safety standard IEC60950-1, the International Electrotechnical Commission after 8 years, IEC62368-1 "Audio/Video, information and communication equipment - Part 1: Safety Requirements" (1st edition) was published on 21 January 2010.Standard.
1, Qi standard, PMA standard. Qi standard: It has two characteristics of convenience and versatility. Different brands of products, as long as there is a Qi logo, can be charged with Qi wireless charger. Mobile phones, cameras, computers and other products can be charged with Qi wireless chargers. PMA standard: Wireless charging standard developed in the United States, with a number of security protection measures.
2, qi2 wireless charging means a new enhanced wireless charging standard. QI2 brings the most to the userThe difference in experience is that the use of QI2-certified wireless charging devices can provide a 15W charging experience for devices that support QI2. WPC sees QI2 as a significant opportunity in 23/24. Qi2 is a new enhanced wireless charging standard developed by the WPC Wireless Charging Alliance in 2023.
3, there are three mainstream wireless charging standards: Power Matters Alliance (PMA) standard: Power Matters Alliance standard is made by Duracell PowermatCompany initiated, and the company is a joint venture between Procter & Gamble and wireless charging technology company Powermat, has a relatively excellent comprehensive strength. In addition, Powermat is a supporting member of the Alliance for Wireless Power (A4WP) standard. 4, in addition, at this stage, electric vehicle wireless charging is still facing the problem of high cost and brand compatibility, it is reported that because the upstream and downstream industry chain has not been opened, it is estimated that the 7kw private wireless charging price is about 20,000 yuan, even if the future wireless charging reaches 1 million setsOrders of magnitude, its cost is still about 30% higher than the traditional charging pile.
5, Abstract: Wireless charging is a new technology, compared with the traditional method of charging with data lines, wireless charging can be transmitted to the mobile phone through the cable, with safe and harmless, low power loss rate, convenient.
6, Qi is the world's first to promote Wireless charging technology standardization organization - Wireless charging Alliance (Wireless Power Consortium, referred to as WPC) launched the "wireless charging" standard, with convenience and versatility of the two characteristics. Different brandsProducts, as long as there is a Qi logo, can be charged with Qi wireless charger.
