Wireless charging is not a chicken rib, but a very useful charger. For people at work, they do not have time to repeatedly plug in the charger, only occasionally check whether there is a text message or phone call. With wireless charging, you can better protect the interface of the phone, and you can also have power anytime and anywhere. They will not worry about what to do when they go out without electricity, just put it on the charging site.
The charge efficiency is not high. Once distanceA little far away charging efficiency will 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.
Because many people think that this function is relatively weak. Now unlimited charging is more troublesome than charging with a data cable. Although wireless charging sounds very tall, but the actual operation is not convenient, many unlimited chargers sinceLow has always been the biggest enemy of limiting the development of wireless charging, especially in recent years, the rapid development of wired fast charging has made many people forget the existence of wireless charging. Fortunately, this problem is gradually being solved.
Wireless charging mobile phone popularity limited factors Wireless charging mobile phone Why rare? On the one hand, the inconvenience of its use form is an important factor. Although the early Nokia Lumia 920 has built-in Qi wireless charging technology, it requires a special case and base, which is not convenient to use. The base's size and charging distance limits also limit the user experience.
1, the meaning of wireless charging is to get rid of the bondage of the data line wireless charging does not make sense , put on the wireless charger can be charged, want to use the mobile phone can be taken down at any time, very convenient. Wireless chargers have a common problem, that is, the charging speed is very slow. Wireless charging technology comes from radio energy transmission technology, which can be divided into two ways: low-power wireless charging and high-power wireless charging.
2, wireless charger refers to the need to charge without the traditional charging power cordThe charger on the terminal device, a variety of devices can use a charging base station, mobile phones, MP3 players, power tools and other power adapters wired charging situation will not exist wireless charging does not make sense . By using the magnetic field generated between the coils to magically transfer electrical energy, inductive coupling technology will become a bridge connecting the charging base station and the device.
3, protection interface Wireless charging does not make sense : Wired charging requires frequent insertion and removal of the charging cable, long-term use may lead to interface damage or wear.Wireless charging eliminates the problem that wireless charging is meaningless, and the mobile phone interface can maintain a good state for a longer time, extending the service life of the mobile phone. Low charging efficiency Wireless charging does not make sense : Compared with wired charging, the efficiency of wireless charging is low. That means it takes longer for users to fully charge.
4, in fact, it has a certain practical significance, so that some accidents can be avoided, and the efficiency will be relatively high, and will not forget to take the charger.
