The charge efficiency is not high. Once the distance is a little far away, the efficiency of charging will be dramatically reduced, and a lot of time and resources need to be wasted to complete the charging, so the use is not meaningful. Safety issues in the charging process. High-power wireless charging devices produce a lot of electromagnetic radiation, yesIt will cause some adverse effects on physical health, but also have interference effects on aircraft and communications. The first practical aspect.
Charging speed may be limited Although many wireless chargers have achieved fast charging, in some cases, their charging speed may still not be as fast as traditional wired charging methods. Especially in the case of low power and the need for fast charging, wireless charging may not meet the needs of users. Higher cost Compared to wired chargers, wireless chargers are usually more expensive.
Despite significant advances in wireless charging technology, there are still some challengesFight. First of all, its efficiency is slightly inferior to the wired charging method, and the charging speed is relatively slow. In addition, the performance of wireless chargers is affected by environmental factors, such as electromagnetic interference and signal interference, which can reduce charging efficiency. In addition, for many consumers, the high price of wireless chargers has become a major consideration for purchase.2, the advantages of wireless charging safety: no power contact design, can avoid the danger of electric shock. Durable: the power transmission element is not exposed, so it will not be eroded by moisture and oxygen in the air; There is no contact, so there is no loss caused by mechanical wear and flaring during connection and separation.
3, wireless charger compared with the traditional wired charging method, has the following significant characteristics: convenientThe wireless charger does not need to plug or unplug the charging cable, and only needs to place the device on the charger to achieve charging, which greatly improves the convenience of charging. Whether in the home, office or public places, wireless chargers can provide users with a more convenient charging experience.
4, vivox100s wireless charging features: convenience: wireless charging saves the trouble of carrying the charging cable and plugging the data cable, making the charging process more simple. Compatibility: The phone supports a variety of wireless charging devices, and users can choose the right charger according to their needs. High efficiency: wireless charging technologyBecause there is no need to plug and unplug the charging cable frequently, the data interface wear of the mobile phone will be reduced a lot. At the same time, the coil of wireless charging of the mobile phone is not exposed to the air, which can also reduce the oxidative corrosion of the charging unit. The wired charging is often inserted and removed easily lead to wear, and the interface is exposed, which is easy to oxidation corrosion. Although wireless charging has many advantages, it is also found that there are many disadvantages in the actual use process. 2, charging speed may be limited Although many wireless chargers have achieved fast charging, in some cases, their charging speed may still not be as fast as traditional wired charging methods. ,Especially in the case of low power and the need for fast charging, wireless charging may not meet the needs of users. Higher cost Compared to wired chargers, wireless chargers are usually more expensive.
3, the disadvantages of wireless charging: can not charge while playing: the current wireless charger is basically a wireless charger base, there is no fixed position design, the mobile phone is difficult to meet the needs of charging while playing. Although there are also vertical wireless chargers that can solve this problem, it will still affect normal use.
4, advantages: The advantage of wireless charger is that we can use the phone at the same timeYou no longer need to unplug the cable for charging. 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.
5, convenience: non-contact, one-to-many charging compared with the general charger, reduce the trouble of plugging, but also avoid the interface is not applicable, poor contact and other phenomenon, the elderly can also be very convenient to use. (2) Versatility: a charger can charge multiple loadsA family buying a charger can meet the needs of the whole family.
6, harm one: charging use. Wireless charging board is generally a flat design, so mobile phone wireless charging is often not suitable for charging while using, not suitable for some application scenarios, such as out of power urgently need to charge but a very important call, you can only use headphones or speakers to talk, rather inconvenient. Bad two: Battery loss.
At present, the wireless charging market is a blank, completely belongs to the blue ocean market, there are business opportunities everywhere, all signs show that wireless charging will be the mainstream power supply of electronic equipment in the futureUnprecedented dividends and tuyere, is worth investing in the project. At present, there are cloud rich brands doing well in China.
Nevertheless, as technology advances, wireless charging technology is expected to improve and become widespread in the future. But for now, it is more a preference of a specific group than an inevitable choice of mass demand.
Wireless charging is evolving and becoming more mature, and may become the mainstream way of charging in the future. With the increasing maturity of the technology, more and more mobile phone brands have added wireless charging function to their latest mobile phones.
Two main matricesThe Wireless Charging Alliance (A4WP) and PMA have announced mutual compatibility, which means that future wireless charging devices based on these two standards will be able to be compatible with each other's phones, greatly expanding the scope of device adaptation. However, there are no details on how to achieve bidirectional compatibility between the two standards. Broadcom chief technology officer Henry-Samueli pointed out that the biggest obstacle to the adoption of wireless charging technology is the inconsistent standards.
Wireless charging is mainly convenient, but it needs to solve testing problems to ensure safety and efficiency. On the future trend, wireless charging is expected to develop, but for nowTechnical difficulties still need to be resolved. Wireless charging testing challenges Power transmission testing for wireless charging is particularly complex, requiring high accuracy and phase calibration. For example, ZLG's PA8000 power analyzer provides a solution for wireless charging testing with its high accuracy and phase calibration capabilities.
WiFi wireless charging technology Wireless charging technology discussion The disadvantage is that the charging is slow, and the WiFi wireless charging has not yetThere is a wide range of popularization, and to use WiFi wireless charging, the premise is that the mobile phone must be supported, and the WiFi must also be upgraded.
Therefore, wireless charging will not have any bad effect on the mobile phone, but for heavy mobile phone users such as Xiao Bian, high-power fast charging will be more suitable.
Of course, wireless chargers also have shortcomings. At present, the charging speed is still faster, and the wired charging can achieve high power charging such as 30W and 40W Wireless charging Technology discussion ; And wireless,Mainly 5W and 10W charging, which is slower. The cost is high, the maintenance consumption is large, and there will be security risks if the standards are not met.
Advantages, easy to use, have their own office or study, that kind of put and fill with the feeling of a great. Moreover, because wpc and pma two charging protocols are supported, so do not buy the official wireless charger can also be used, Taobao to buy dozens of pieces can be used, the choice is very many. Disadvantages, charging is a bit slow, because wireless charging conversion will have losses. It's a little hot. I can't play happily with my phone while charging.
The charging speed is relatively slow. Fast phoneIn the era of charging, wireless charging is very slow. Now most of the wireless charging only support 5W charging, a little faster is only 5W. And wireless charging really can not meet the Wireless charging technology discussion our needs.
Wireless charging of Phone11, the theoretical peak power is 5w, but in most cases it is 5w power. You can replenish the power when you are not in a hurry, but the speed is slow, and it is not recommended as a normal charging method. Wireless charging function does not need to be set, only need to put the phone on the wireless charging board to charge.It is recommended to buy the charger provided by the official, third-party chargers may have compatibility problems.
