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. The first safety question during chargingtopic. 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.
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 simple phone calls and listen to music. Encounter game play half of the phone power shortage, can only be wired charging faster and more convenient.
However, wireless charging also hasDisadvantages. 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.
The charging speed is relatively slow. Now most of the wireless charging only supports 5W charging, slightly 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, flatWhen there are more places to use electricity, mobile phone charging is also a common thing, so we like to charge relatively fast feeling, and wireless charging just cut this off, really do not meet our needs.

The price is only 99 yuan, very high cost performance, whether it is Xiaomi users or other mobile phone users who support wireless fast charging, it is worth considering.
This 10W universal fast charger supports QC protocol, which is suitable for most wireless charging devices, although it is enough for iPhone 8 users like me, but after upgrading to IOS11, wirelessThe charging speed has decreased. Android users will need a higher power version, as more than 18W is needed to fully meet demand.
Brands such as Huawei and Xiaomi have also introduced wireless fast charging, indicating the industry's acceptance and promotion of wireless charging. Summary Wireless fast charging does bring some convenience, as long as the correct charging habits are used, with technical upgrades, there is no need to worry about battery loss. For busy office workers, wireless fast charging provides the possibility of fragmented time charging. The popularity of wireless charging is the general trend, and it will become the norm in daily life like wired fast charging.
This itemThe technology uses a low voltage and high current fast charge mode, which is relatively fast when the phone is charged in the early stage, but the compatibility of this fast charge technology is poor, and it can only be used on oppo's mobile phone, which must be paired with the relevant data cable and battery and charger, so it does not have any effect on other mobile phones.
The results of the 20W wireless flash enrichment test of the Mi 9 show that its charging speed exceeds the 18W cable speedCharging, even faster than the Mi 8's wired fast charge.

Huawei wireless charging damaged battery. Whether it is wireless charging or wired charging charging time will be hurtHowever, compared with wireless charging and wired charging, because wireless charging will generate more heat in the process of charging, high temperature is not good for the battery, so wireless charging is more damaging to the battery. However, when using wireless charging, pay attention to ventilation.
Low efficiency: energy storage and transmission efficiency is not as good as real contact. Slow charging speed: Due to low efficiency, the charging speed is slow at the same input power. High cost: The charger needs to have an electronic line to promote the wireless coil, and the electrical device needs to have an electronic device to change the power, both also need to have a wireless coil, so the cost ratio is straightContact is high.
Wireless charging, speaking of this, reminiscent of black technology, it is also a progress in science and technology, or should be supported.
