1, the charge efficiency is not high. Once you get a little bit further away the efficiency of the charge isWill be dramatically reduced, need to waste a lot of time and resources to complete the charging, so the use of little sense. Safety issues in the charging process. High-power wireless charging equipment will produce a large amount of electromagnetic radiation, which will cause certain adverse effects on health, but also have interference effects on aircraft and communications. The first practical aspect.
2, it is not convenient to carry, can not play while charging in addition, most of the wireless charging base is designed to be larger than the wired charging head, and it is not very convenient to carry out. And when using wireless charging, the phone can not pick up and play while charging, can only say a simple call and listenMusic. Encounter game play half of the phone power shortage, can only be wired charging faster and more convenient.
3. However, wireless charging also has disadvantages. Due to the use of electromagnetic induction technology, wireless charging is relatively less efficient, which means that the amount of power charged in the same time may be less than that of wired charging. In addition, since wireless charging requires the use of a relatively close distance between the transmitter and the receiver, it will be affected by environmental factors, and if the environment is too noisy, it may also affect the effect of wireless charging.
4, the charging speed is relatively slow. Now most of the wireless charging only support 5W charging, slightlySlightly faster there is 5W, although there is a slight gap, but it is not fast enough to go, and now our mobile phone fast charging technology is already very developed, usually there are more places to use electricity, mobile phone charging is also a common thing, so we like the feeling of charging relatively fast, and wireless charging just cut this off, really do not meet our needs.
5, although wireless charging has many advantages, but in the actual use process, also found that there are many shortcomings. Compared with wired charging, wireless charging mainly has the following disadvantages. 1, the distance is too small, just a transition technology because the magnetic field is very attenuated in the airh2 id=' Can Xiaomi Wireless charging support several devices at the same time '> Can Xiaomi wireless charging support several devices at the same time
Xiaomi wireless charging bank can support charging for 3 devices at the same time, multi-channel charging is very powerful, of course, it has such convenient charging characteristics, it will inevitably sacrifice a little thing.

In their blog announcement, Xiaomi revealed the breakthrough system, which not only charges multiple devices simultaneously, but also penetrates barriers and, through clever rectifier circuits, converts these millimeter waves into a source of power to charge the phone's battery. Four years ago, Disney used Tesla's coil circuit as a basis for demonstrating the potential of wireless energy transmission.

Surprisingly, after 800 times of charge and dischargeAfter cycling, the battery can still maintain more than 90% of the effective capacity, fully ensuring the healthy life of the battery. Compared with competing products in the market, Huawei P40 Pro supports 40 watts of fast charging, OnePlus 8 Pro is 30 watts of wireless fast charging, and iPhone 12 is only 15 watts, and Xiaomi's wireless charging speed is almost twice that of Huawei and Apple.
According to the Xiaomi official micro, this is the first time that Xiaomi wireless fast charge crossed the 80W mark, and it already has a fairly fast charging speed, such as only 19 minutes to fill a mobile phone, 8 minutes to charge to 50%, charging speedAlready on par with traditional wired charging. But many people may not be surprised by this, because before the Xiaomi 10 Supreme version has used 50W wireless fast charging, wired charging technology has also broken through hundreds of watts.
Xiaomi 80 watt wireless fast charge to 4000mAh battery for charging, 8 minutes can be charged 50% (about 2000mAh), 19 minutes can be full of 100%, charging speed is very amazing. It is reported that most of the flagship mobile phones on the market still use 65 watts of wired fast charge, which generally takes more than 30 minutes to fill the 4000mAh battery.
