Wireless fast charging is a combination of wireless charging technology and fast charging technology, and the mainstream models on the market now support wireless fast charging technology. Wireless fast charging mobile phones are Xiaomi Huawei P40, Mate30, Mate30 pro and so on. Wireless charging technology Because the charger and the electrical device transmit energy by magnetic field, the two are not connected by wire, so the charger and the electrical device can be non-conductiveElectrical contact exposed.
In general, wireless fast charge is a wireless charging method based on magnetic resonance, electromagnetic induction and other technologies, which eliminates the tedious operation of wired charging and brings users a more convenient and efficient charging experience. Its wide application and continuous technological development indicate that wireless fast charging will become the mainstream way of charging electronic devices in the future.
Wireless fast charge is the use of electromagnetic induction principle, there is a coil in the sending and receiving end, the sending end of the coil connected to the wired power supply to generate electromagnetic signals, the receiving end of the coil induction of the sending end of the electromagnetic signal to generate current to charge the batterySimply understood as a transformer without a magnetic core. Compared with wired, wireless charging has less loss to the battery, and wireless charging technology is more convenient and has lower charging heat.
Wireless charging is fast charge or slow charge depends on the phone charger, if the charger is high voltage fast charge, wireless charging is wireless fast charge; If it is an ordinary charger, wireless charging is wireless slow charging. The correct way to use a wireless charger: Connect the charger to a power source. Please use the charging head, charging cable and wireless charging base purchased by yourself. Place the charger on a horizontal surface or manufacturerWireless fast charging of more than one hour is not as fast as wired fast charging of 1 hour and 30 minutes, which is not considered fast charging. Unexpectedly, the wireless fast charging efficiency of 60% when the 18W is charged for 2 and a half hours.
Different, the wireless charger will have a loss when charging, and the loss is between 30-40 percent. So the ordinary charger is faster than the wireless charger. There are already fast chargers and fast wireless chargers, but the results are the same. For example, the fast charging Samsung S8 takes 90 minutes, then the fast wireless charger takes 190 minutes, which is the result of my own actual testing.
ExceptIn addition to the advantages of convenience, the disadvantages of wireless charging are still many. For example, the charging time is too slow, Samsung Note 5 fully charged at least 6 hours or so; If you use a fast charge, it will be full in a little more than 2 hours. Although wireless charging also supports fast charging now, it is still not as fast as wired charging, after all, wired charging already supports 40W fast charging, and wireless fast charging is only 15W.
1, although there are peopleWorry that wireless fast charging will harm battery life, but in fact, wireless fast charging itself will not. Battery life is affected by a variety of factors, such as faulty charging habits (excessive discharge and frequent charging), high temperatures, and non-compliant charging devices. Lithium batteries have no memory effect, and appropriate "use with charge" is beneficial to battery health.
2, however, wireless fast charging does not directly lead to reduced battery life. Battery life is affected by a variety of factors, lithium batteries have no memory effect, frequent charging, power off does not affect. What can really damage a battery are wrong charging habits, high temperatures, and substandard charging equipment. For example, OPPThe 40W wireless flash charging technology adopted by the O Ace2 takes into account charging efficiency and safety through series dual cell and air-cooled heat dissipation technology.
3, the reason for too fast battery loss is more due to improper use, such as excessive use of mobile phones, the use of unstable chargers, wrong charging habits, and power consumption operations when charging. Wireless fast charge does a better job of controlling temperature and power conversion, and the impact on the battery can be controlled as long as the quality of the device is reliable. Wireless fast charge is especially suitable for those who pursue convenience, such as busy office workers.
1, this feature will not have any negative impact on the phone. In response to this problem, some people said that they often use fast charge, but the mobile phone battery is very normal, there is no problem. Wireless charging is to reduce people's trouble that the data line is too cumbersome. Now wireless charging without the data line people charging becomes very convenient and simple, so the frequency of people charging will also increase.
2, in theory, wireless fast charge and mobile phone fast charge, are specially designed for mobile phones, the hand machineIt is important to understand that pools do no harm. However, when the user chooses a wireless charger, it is best to choose a charger that is compatible with the mobile phone, or choose a charger produced by a regular manufacturer.

Wireless bidirectional fast charging is a new charging technology that can be used in a variety of scenarios such as mobile devices and electric vehicles. itFast charging, bidirectional transmission, and no need for traditional chargers and cables. This technology is based on the principle of electromagnetic induction, by wirelessly transmitting electrical energy to the device to charge. When the internal charge of the device is full, the excess power is reversely transmitted back to the charger.
Two-way fast charge means that both output and input support fast charging; The output supports fast charging, that is, when the charging treasure charges the mobile phone, the charging treasure and the mobile phone support fast charging, and the input supports fast charging, that is, when the charging treasure charges the charger and the charging treasure support fast charging. At present, the charging speed is generally 5V, 2A is the base benchmark,Charging power more than 5V, 2A is a fast charge concept, in principle is also divided into two directions of pulling high voltage and increasing current.
Fast charge protocol: PD QC fast charge power: 10W Wireless 18W wired This South Carolina wireless charging treasure battery capacity is 10000 MA, support QC18W and PD18W wired fast charge function, also support 10W wireless fast charge function. The South Carolina wireless power Bank POW2 uses a triple heat dissipation design, whether it is wireless or wired charging will not be hot.
November 25 news, this afternoon Huawei officially released its subsidiaryThe new MatePad Pro tablet computer, Yu Chengdong mentioned when introducing this tablet computer, this tablet is the first two-way wireless charging tablet. Huawei MatePad Pro is the world's first two-way wireless charging tablet, equipped with 7250mAh large-capacity battery, support 40W super fast charge 15W forward wireless fast charge, 5W reverse wireless fast charge technology.
Wireless fast charging is a combination of wireless charging technology and fast charging technology, and the mainstream models on the market now support wireless fast charging technology.
