1, 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.
2, due to the heating problem in the electromagnetic conversion process, taking into account the safety of electricity and other factors, manufacturers have to control the power. This is also a reason for the gradual disappearance of wireless charging. After all, wired fast charge has been deliveredTo 120W, most mobile phones equipped with fast charge are more than 60W, has exceeded the wireless fast charge, so wireless charging because of the technical requirements of the equipment, has gradually opened the gap with wired fast charge.
3, charging power is limited, charging technology is not interoperable between different brands of the current mobile phone power update quickly, a day to increase a power, from the original 18W fast charge into a variety of fast charge power, 30W, 45W, 65W, and now there are 120W super fast charge power, This also leads to a lot of wireless charging boards in the world at present, if you chooseGet it wrong and you can't experience the full charging power.
4, compared with wired charging, wireless charging is more convenient, only need to place the mobile phone in the energized state of the wireless charging board can charge the mobile phone, lift the charging, you can not not mention the charging power, the power of the wired charger is generally relatively high, the lower point is 30W, higher point can even reach 120W. 5. Challenges abound in the development of wireless charging technology: the solution must be practical, inexpensive, capable of charging multiple devices simultaneously, and within a reasonable range of the power transmitter. Power transmitter (especially in the home)It is often difficult to see, in fact, in some cases it may be set inside furniture or walls. In an ideal situation, charging can take place even if there is no directly visible line between the power transmitter and receiver. 6, it can be said that in today's era of wireless charging has become 5G high-end machine standard, this disadvantage of P40 is undoubtedly unacceptable, and its battery capacity is only 3800mAh, battery life is unacceptable, and it is only equipped with rear three cameras, these shortcomings indicate that P40 is not commensurate with its positioning. So people would rather choose the follow-up Huawei P40pro and pro, it makes sense not to choose the P40.
1, wireless charging benefits: first: reduce loss. 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.

Flexibility: Wireless charging eliminates the need for a specific charging cable. Users no longer need to carry and connect a specific type of charging cable, and can charge at any time on multiple charging docks that support wireless charging.
3, the benefits of wireless charging reduce loss As we all know, when using wireless charging, just connect the wireless charging board to the power supply first, and then place the device that supports wireless charging inOn the wireless charging pad. 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.
4, the biggest advantage of wireless charging is convenient. Wireless charging has little impact on mobile phones, but when all electronic products support wireless charging, 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 chargingHelps improve safety.
5, the advantages and disadvantages of wireless charging are as follows: Advantages: wireless charging can reduce the plug plug when wired charging, thereby extending the service life of the mobile phone charging interface; Wireless charging technology is suitable for a variety of device types; Wireless charging enables a cleaner, cleaner device appearance, eliminating the clutter of traditional cables.
6, wireless charger is good, convenient, safe and durable; The disadvantages are bondage, high price and low efficiency. The 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 problem=' What is the difference between wireless charging and wired charging bank? Which is better? '> What is the difference between wireless charging and wired charging bank? Which is better?
Slightly slower charging speed: Compared with wired charging treasure, even if it has fast charging, wireless charging treasure Why wireless charging is cheaper than wired charging Charging speed will be slightly slower, especially for large-capacity batteries Why wireless charging is cheaper than wired charging equipment, charging time is longer. Compatibility limitations: Wireless charging bank is requiredReady to support Qi or its Why wireless charging is cheaper than wired charging He wireless charging standards, do not support wireless charging technology can not enjoy its convenience.
each has its own advantages: wireless charging is convenient, without connecting the mobile phone to the charger, it can be placed on the charging board Why wireless charging is cheaper than wired charging ; Wired charging is more stable, and the charging speed is faster than wireless charging.
The second kind of wireless charging, its working principle is the most used electromagnetic induction, wireless charging less Why wireless charging is cheaper than wired charging the bondage of the line, each charge on the go, compared with wired charging, it does not plug and unplug the tedious data cable, so charging is safer and faster, its disadvantage is that the charging is slow.
What is the difference between wireless charging and wired charging bank? Although both are used to charge devices such as smartphones, there are some differences. Simply put, wireless charging is more convenient, does not require wire entanglement, can remove the trouble of wire; The wired charging treasure is faster in charging speed, such as the Secretary-General is a wired chargingBao, support PD two-way fast charging, charging speed is faster than general products.
The difference between wireless charging and wireless charging is that wireless charging makes mobile phone charging more convenient. Wireless charging, as long as the mobile phone has a built-in wireless charging function, or install a receiver, and then put the mobile phone on the wireless charger, you can achieve mobile phone charging. Wireless charging is evolving and becoming more mature, and may become the mainstream way of charging in the future.
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.
Due to the heating problem in the electromagnetic conversion process, taking into account the safety of electricity and other factors, manufacturers have to control the power. This is also a reason for the gradual disappearance of wireless charging. After all, wired fast charge has developed to 120W, most handsThe fast charge equipped with the machine is more than 60W, which has surpassed the wireless fast charge, so wireless charging has gradually opened the gap with the wired fast charge because of the technical requirements of the equipment.
The main reason is that the wireless charging current is too small. Wireless charging is limited to material problems and technical problems resulting in low efficiency. Wireless charging is only suitable for use when sleeping, while watching and charging can not keep up. In addition, the wireless charger charger is too large, it is better to plug in the charger directly. The last one is that modern fast charging technology is unmatched by wireless charging.
The charging power is limited, and the charging technology is not interworking between different brandsThe current mobile phone power upgrade quickly, a day to increase a power, from the original 18W fast charge into now a variety of fast charge power, 30W, 45W, 65W, and now 120W super fast charge power, which also leads to the current world of wireless charging board a lot of very mixed, if the wrong choice can not experience the full charging power.
Because there is a heating problem in the electromagnetic conversion process, considering that the lithium battery is not stable when heated, the mobile phone manufacturer will control the power to reduce the heat. Take the iPhone XR from previous years, which only supports wireless charging up to 5WIt takes at least two to three hours to fully charge. Although wireless charging is the research and development direction of mobile phone manufacturers in the future, the charging efficiency of wireless charging is still less than that of wired charging.
1, wireless charging and wired charging have their own advantages, which is better to choose depending on the specific use scenario and needs.
