2, the current mainstream wireless charging power standard10W, corresponding to the 5V2A charging specification. The wireless charging power supported by Apple phones is also generally in line with this standard. Some devices may support lower power, such as 5V5A, corresponding to a 5W charge rate. In contrast, the power of wired charging is usually around 18W, and the speed of wireless charging is indeed slower.
3, there are three mainstream wireless charging standards: Power Matters Alliance (PMA) standard: Power Matters Alliance standard is made by Duracell Powermat company 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, there are four basic principles of wireless charging, respectively, electromagnetic induction charging, magnetic resonance charging, radio wave charging, electric field coupling charging, the mainstream standards on the market mainly Qi standard, PMA standard, A4WP standard, iThere are five kinds of NPOFi technology and Wi-Po technology. Let's take a look at the principle of wireless charging.
5, HONOR Magic6 if it supports wireless charging, then it may adopt the mainstream wireless charging standard on the market, such as the Qi standard. This means that users can buy a QI-compliant wireless charger to charge the HONOR Magic6 without worrying about compatibility issues. In addition, the wireless charging function can also be combined with other functions of HONOR Magic6, such as fast charging, intelligent charge management, etc., to provide users with a more comprehensive and convenient charging experience.
6, pro, etc. Wireless charging technology Because the charger and the electrical device transmit energy by magnetic field, the two are not connected by wires, so the charger and the electrical device can be no conductive contact exposed. The principle of fast charging of mobile phones is to increase the input value of the charging voltage or current. However, in order to truly realize fast charging of mobile phones, it also needs supporting circuits and hardware. The fast punch technology mainly includes Qualcomm's Quick Charge and Mediatek's Pump Express.
Apple iPhone series: Starting with the iPhone 8, subsequent iPhone models support wireless charging. Samsung Galaxy Series: Most models of Samsung's Galaxy S series and Galaxy Note series support wireless charging. Huawei P Series and Mate Series: Huawei's flagship phones such as P40 and Mate 40 all support wireless charging technology. Some Xiaomi flagship models, such as the Mi MIX series, also support wireless charging.
iPhoneX: The home button is goneWith an 8-inch OLED fringe screen, the iPhoneX is the first mobile phone with a fringe screen, and it is also the first OLED screen that meets the iPhone standard and supports wireless charging. 1,000,000:1 contrast ratio, deeper black, better brightness, more precise brilliant colors, rear rear dual shot, 12 megapixel wide Angle lens and 12 megapixel telephoto lens combination, support portrait mode background blur.
Huawei Mate 40 Pro: a total of Mithril, bright black, white glaze, summer poplar (plain skin), autumn poplar (plain skin) 5 colorso, oppoFindX5pro, oppoaceoppofindn, oppox2021. The opporeno8 is a smartphone released by OPPO.
Samsung Galaxy: Most phones in the Samsung Galaxy series support wireless charging. Whether it is the Galaxy S series or the Galaxy Note series, as long as the back of the phone is not shielded by metal materials, it can be charged wirelessly through the Qi standard charger. Google Pixel: Google PixelSeries phones also support wireless charging.
vivo supports wireless charging mobile phone models including iQOO11Pro, X90Pro, X90Pro, XFold, iQOO10Pro, X80Pro Snapdragon version, X80Pro Guet version, XFold, XNote, iQOO9Pro, X70Pro vivo mobile phones such as iQOO8Pro.
Qi authentication. At present, the electronic products that support wireless charging mostly use the Qi standard, which currently includes more than 90 companies including Apple, Samsung and NokiaAll the phones have passed the Qi standard certification. Products certified by the WPC Alliance will be marked with the word "Qi" LOGO, which means that the charger has been tested and is safe and Qi compliant. In order to be able to use the equipment normally and eliminate safety risks, please use wireless charging accessories with Qi certification.
There are many mobile phones that support wireless charging. At present, flagship phones of major brands such as iPhone 11 and above, Samsung Galaxy S2, Huawei Mate 30 Pro and Mi 11 have built-in wireless charging function. In addition, some othersBrands of mobile phones such as LG, Sony, OnePlus and others also have models equipped with this function.
There are many mobile phones that support wireless charging, mainly including flagship models and high-end series of major brands. Wireless charging has become a standard feature on many high-end phones. The following is a detailed explanation about supporting wireless charging mobile phones: Flagship models Major mobile phone brands, such as Apple, Samsung, Huawei, Xiaomi, etc., their flagship models usually support wireless charging.
1, the most used is Ti's chip, about 12. There are many options for launch, and we're one of them.
2, wireless charging PCB, different functions, the required components are different. The required components are: resistor, capacitor, resonant capacitor, resonant coil, MOS tube, control chip, protocol chip.
3, the realization of wireless charging function requires a wireless transmitter module and receiving module, and now the new mobile phones launched by the major mobile phone brands on the market have built-in wireless charging receiving modules, and some mobile phones without built-in receiving modules need an external receiving coreThe use of the receiving chip is also very simple (it can be inserted into the charging port of the phone); The wireless charger needs to be connected to the power supply, but the phone can be placed on the wireless charger for wireless charging of the phone.
4, iPhone11 as Apple's flagship iPhone11 also supports wireless charging, but relative to domestic mobile phones, the charging rate may be slower, but other aspects are still very strong, such as iPhone11 has a variety of different colors to choose from, but also the new addition of green and purple, Very little fresh.
5, for example, milletThe 9 is equipped with the world's first 20W wireless flash charging technology, while the Samsung S10 series supports wireless accelerated charging and wireless shared charging technology. Huawei Mate20PRO was a leader at that time, with reverse wireless charging function. When buying a phone that supports wireless charging, there are a few things to be aware of. First, make sure the coil of the wireless charger is properly aligned with the phone.
