1. Open the mobile phone jacket, plug the receiving module into the charging port, connect the patch to the charging port of the mobile phone, and then put it on, remember to face up. Since the energy is transmitted between the charger and the electrical device by a magnetic field, no wires are connected between the two, so the charge is madeThe device and the electrical device can be made without exposing the conductive contact. It is important to note that whether it is a mobile phone or a charging bank, it has a wireless function, that is, a wireless coil.
2, first open the connection Settings on the phone, enable Bluetooth or NFC function. Touch the NFC area on the phone screen or select the wireless charger from the Bluetooth connection list to connect. After the connection, the wireless charging bank will automatically identify the type of mobile phone and adjust the output current according to different mobile phone models to provide the appropriate charging current for the mobile phone.
3, reallyDo you have a wireless power bank? In 2019, the answer is obviously yes, although there are not many wireless charging products in the real sense on the market, but the overall technology has been relatively mature. The principle of wireless charging treasure is also mainly wireless transmission, eliminating the entangling of wires. 4, wireless charging treasure is the world's most advanced technology, rich in micro volume, large current, micro temperature rise, metal resistance, do not misoperate and other advanced technical indicators, only it can set many essence in one and successfully built into the battery, can easily turn a variety of different brands of mobile phones into wireless charging mobile phones. Mainly at a later dateMaybe it should be popularized.
The first is that the future iPhone will directly cancel the design of the charging port. In addition to the iPhone, Apple Watch, and AirPods, Apple also plans to transition the iPad to wireless charging. Apple may not use this interface for the long term, but instead transition to wireless as soon as possible. Apple's no-hole approach has long been reported. The iPhone 14, which went on sale in the United States this year, eliminated the SIM card slot, which was also seen as a step toward Apple's move toward an iPhone with no end.
There are Revelations that the iPhone13 or cancel the charging portThat means that in the future, Apple mobile phones can not use wired charging methods. For us, mobile phones are basically wired charging. Because, to buy a wireless charging device price is still relatively expensive. If the iPhone13 cancellations the charging port, it must affect its sales to some extent.
Apple's continuous exploration of wireless charging technology indicates that the future iPhone may completely bid farewell to the lightning interface, and even the complimentary wired charging cable. This means that users will need to buy specialized wireless charging devices, which will undoubtedly bring new ones to the marketConsumption trends. In short, the prospect of an Apple laptop charging the iPhone wirelessly not only demonstrates technological progress, but also heralds a profound change in the interface design of Apple devices.
Although the technical content of the equipment is high, the economic cost of the equipment is higher and the maintenance cost is large. Because of the realization of long-distance high-power wireless magnetoelectric conversion, the energy consumption of the equipment is high. With wireless charging device distance and powerThe higher the rate, the greater the dissipation of useless work.
No strong radiation, no effect on the human body! The main principle is: the way of wireless charging is electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, etc. Most of the wireless charging of mobile phones uses the principle of electromagnetic induction.
The harm is relatively small can be ignored, although wireless charging technology has appeared in the 19th century, but the popularity of mobile phone applications is not high. It uses the principle of "magnetic resonance" to allow the wireless charger to transmit an electric charge through the air to the phone's battery. Many wireless chargers on the market do not have a labelThe electromagnetic radiation standard for wireless chargers has not yet been introduced.
1, the principle of wireless charging is that through near-field induction, the wireless charging device conducts energy to the charging terminal device, and the terminal device converts the received energy into electrical energy and stores it in the battery of the device. The principle of energy conduction is inductive coupling, which ensures that there is no exposed conductive interface. Not only can eliminate the messy transmission lines between devices, forElectronic devices such as electric toothbrushes that are in constant contact with conductive media such as liquids are also safer. 2, wireless charging technology has not been widely popular reasons are: the number of terminals less two years ago Nokia Lumia 920 built-in Qi wireless charging technology, and randomly equipped with wireless charging board, but no other manufacturers follow up. Although some third-party manufacturers have also launched wireless charging accessories, but need to install a special shell, it is not compatible with other digital devices, the use of inconvenient form.
3, wireless charging is a convenient charging technology, without the use of physical cable that isCan charge the device. Wireless charging technology uses principles such as electromagnetic induction or radio wave transmission to charge devices without a physical connection line. This technology transmits energy through a magnetic field or radio signal between the charger and the device, allowing the device to be charged. Compared with the traditional wired charging method, wireless charging brings greater convenience and comfort.
4, the principle and hardware requirements of this way are relatively simple, and the relevant standards are developed earlier, such as the Qi Wireless charging standard that we are familiar with is made by the WPC (Wireless Power Consortium, wireless charging Alliance) Formulated. Therefore, this kind of charging technology has achieved scale, its production cost is low, and has passed the test of the market, and is more popular. The disadvantage is that due to the limitation of the technical principle itself, the transmission distance is too short, and with the increase of the distance, the loss of wireless charging will increase and the efficiency will be reduced.
5, the only way to popularize: universal standards and mobile phone manufacturers support the formation of universal standards is undoubtedly long and tedious, but it is the only way for wireless charging technology. Most importantly, they need the backing of a mobile phone giant such as Apple or Samsung to become widely available. Imagine if Apple'sThe iPhone series began to support some standard wireless charging technology, and popularity is obviously not far away. 6, with the gradual popularization of urbanization, it will be found that there are also mobile phone wireless charging street lights on the streets of Wuhan, which provides a lot of mobile phone parties with considerable convenience, but the invention principle of a street lamp is actually very simple, similar to smart watches, but also through physical feedback to carry out stable charging, but also to enhance the value of charging.
1, so after the popularity of wireless charging, how much will it improve the charging efficiency? Unlike ordinary charging, wireless charging does not require direct contact, but uses electromagnetic induction to charge. The popularization of wireless charging can reduce the construction of charging piles and charging stations, which can reduce land costs and related operating costs.
2, low charging efficiency: compared with wired charging, wireless charging efficiency is low. That means it takes longer for users to fully charge. In addition, since wireless charging requires energy conversion between transmission and reception, it can beCan result in shortened battery life. Slow charging speed: Due to the low efficiency of wireless charging, the charging speed is relatively slow. This causes users to have to wait longer to complete the charge.
3, the efficiency of wireless charging is lower than that of wired charging, but in the future, with the rapid progress of wireless charging technology, it is likely to be better than wired charging in charging efficiency. However, at present, the technology of wireless charging is not advanced enough, so the charging efficiency of wireless charging technology is lower than that of wired charging. At this stage, wireless charging is more as a supplement and auxiliary to wired charging.
4, wireless charging has little impact on mobile phones, but when all electronic products support wireless charging function, the convenience brought to users is more interesting. Apple says future models of AirPods wireless headphones will come with AirPower-enabled charging cases, so users can charge them simply by placing them on a charging pad. Wireless charging helps improve safety.
Wireless charging technology has not been widely popularizedThe reasons are: the number of terminals is less two years ago, Nokia Lumia 920 built-in Qi wireless charging technology, and randomly equipped with wireless charging board, but no other manufacturers followed up. Although some third-party manufacturers have also launched wireless charging accessories, but need to install a special shell, it is not compatible with other digital devices, the use of inconvenient form.
Wireless charging mobile phone popularity limited factors Wireless charging mobile phone Why rare? On the one hand, the inconvenience of its use form is an important factor. The early Nokia Lumia 920 had built-in Qi wireless charging technology, but required a dedicated case and baseThe seat is not convenient enough to use. The base's size and charging distance limits also limit the user experience.
Wireless charging application scenarios Limited mobile phones want to wireless charging must use the charging base, if off the base, the mobile phone can not charge, which is the same as the wired fast charge to rely on the charging line and charging head. The phone must be static, and it is impossible to play a game while charging.
