The reasons for the national ban on 100w wireless charging may be: wireless charging technology standards are immature: the current wireless charging technology standards are not mature, there are some technical bottlenecks and security risks, so the state limits the power and safety of wireless charging equipment. High cost of wireless charging equipment: Wireless charging equipment needs to use high powerWireless charging coils and batteries, but also need to cooperate with related technology and equipment, the cost is high.
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.
Depending on what type of charger the wireless charger is, the general 100w charger supports 100w to 120w charging head. The wireless charger is carried out using the principle of electromagnetic inductionCharging equipment, its principle is similar to the transformer, through the sending and receiving end of each arranged a coil, the sending end of the coil under the action of power to the outside world to send electromagnetic signals, the receiving end of the coil received electromagnetic signals and electromagnetic signals into current, so as to achieve the purpose of wireless charging.
The wireless charging function of HONOR Magic4 Pro is designed to support 100W wired super fast charge and 100W wireless super fast charge, which is also a very rare "double hundred watt" fast charge mobile phone. However, the country's 2022 wireless charging for mobile devices has also made the latest limitation: Glory wireless chargingElectrical protocols are WPC Wireless Charging Alliance Qi certified.
2, 1: Reduce the lossCost. As we all know, when using wireless charging, you only need to connect the wireless charging board to the power supply, and then place the device that supports wireless charging on the wireless charging board. Although wireless charging still needs to be connected to the power supply, it can reduce the use of data lines and avoid a large amount of loss and waste of data lines, which is relatively an environmentally friendly charging method. Two: high adaptation rate.
3, bound: wireless charging needs to be adsorbed on the charging base, can not be moved at will, the user is more bound than wired charging. High price: The principle of wireless charging is different, resulting in the cost of wireless chargers is usually higher than that of wired chargers. The effectLow rate: Due to the low efficiency of wireless charging, under the same input power, the charging speed is slower than the line charging, especially the fast charging function of some brands. Most models do not support wireless charging because of the technology and cost of wireless charging, generally low-end models do not support wireless charging, only those high-end flagships have wireless charging function. This means that only users who can afford high-end flagship have the opportunity to use wireless charging, the target group is limited, and it is still a relatively small part of the market, which cannot be popularized.
Basically no damage: Wireless charging technology uses the principle of electromagnetic induction to transmit electrical energy through magnetic and electromagnetic fields, which has no direct damage to the internal structure of the mobile phone battery. Modern mobile phones have built-in wireless receivers with voltage and current ratings, so wireless chargers are safe for mobile phone batteries under normal use. The wireless charger has a high energy conversion rate, and can automatically adjust the current according to the battery capacity, avoid overcharging or overheating of the battery, and protect the battery safety.
Wireless charger does not harm the phone. The wireless charger uses electromagnetic induction technology, which transmits energy by using a magnetic field generated between coils, coupling the current from the charging disc to the mobile phone battery, for the battery, its charging process is no different from that of an ordinary wired charger.
Wireless charging itself will not cause damage to the battery, but the charging temperature is too high or too low and the charger material and other factors will have an impact, so it is recommended to use a regular genuine charger, and avoid a long time of fast charging. Wireless charging is a short-range wireless charging technology, compared with traditional wired chargingElectricity, which converts electromagnetic energy into electricity and transmits it directly to the receiver, so as to achieve the purpose of charging the phone without connecting the charging line.
1, therefore, based on the distance is very close, and it is safe and low voltage, so wireless charging is safe, there is no danger of electric shock.
2, from the technical point of view, wireless charging is harmless for human safety. Wireless charging uses the principle of resonance, that is, magnetic field resonance, which only transmits energy between coils with the same frequency, and other devices cannot receive it, indeedThe safety of electromagnetic radiation! --. In addition, the magnetic field used for wireless charging itself has no negative effects on the human body. However, the economic costs and maintenance costs of wireless charging devices cannot be ignored.
3, wireless charging itself will not cause damage to the battery, but the charging temperature is too high or too low and the charger material and other factors will have an impact, so it is recommended to use a regular genuine charger, and to avoid a long time of fast charging. Wireless charging is a short-range wireless charging technology, compared with traditional wired charging, it converts electromagnetic energy into electrical energy and transmits it directly to the receiver, so as to achieve mobile phone zeroNeed to connect the charging cable to achieve the purpose of charging.
1, wireless charger is good, convenient, safe and durable; The disadvantages are bondage, high price and low efficiency. Advantages of wireless charger: Convenient: wireless charging belongs to one-to-many charging, which solves the problem that the interface is not applicable, and also avoids the phenomenon of poor contact caused by repeated plugging and unplugging of the mobile phone interface, which can better protect the mobile phone interface.
2, advantages: The advantage of the wireless charger is that we can use itThe phone is charged at the same time, no longer need to unplug the data cable. In addition, it can be taken at any time, which is more convenient than charging with a data cable. At the same time, it can provide certain support for the phone, making the phone charge more stable. Disadvantages: One disadvantage of wireless chargers is that the charging speed is relatively slow, and most wireless chargers only support 5W or 5W charging power.
3, wireless charger good, pros and cons are as follows: Advantages: In order to improve the unity of the mobile phone now most mobile phones are no longer with the headphone hole this design, but many users said that the headphone hole design is not humanized. But with a wireless charger
