1, the first is electric field coupling charging. First, there are two sets of asymmetrical electric dipoles on the phone and charging device. When they are close together, they produce a coupling phenomenon and achieve the transmission of current. The transfer efficiency is good, but there are distance restrictions, and large capacity charging stations are required. The second is magnetic resonance charging, with the above electric field notSame. This method generates electrical energy through the resonance of the same frequency magnetic field generated by the resonators at both ends.
2, wireless charger use radio wave transmission, radio wave is not only a kind of electromagnetic wave, its own can also transmit energy, and can penetrate the air, so that wireless power transmission is possible.
3, wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, wireless charging of mobile phones mostly uses the principle of electromagnetic induction. Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger transmission coil) will generate a magnetic field, whichWhen his unenergized coil (the charged coil on the phone) is close to the magnetic field, it generates an electric current, which charges the phone.
4, Huawei P60 wireless charging is a new way of charging, it allows you to charge your Huawei P60 mobile phone without plugging in a cable. This charging method uses a technology called "electromagnetic induction", when you use Huawei P60 wireless charger, just need to put the phone on the charger, electromagnetic induction technology will let the phone automatically start charging.
5, electromagnetic induction charging, very simple, and high school electromagnetic induction principle is similar, wirelessThe charging seat and terminal used for charging are respectively built in coils, so that the two are close to begin to supply power from the charging seat to the terminal. Many wireless charging mobile phones are this principle, but the location must be relatively uniform in order to charge efficiently. And there is also coupling radiation problem, electromagnetic wave coupling will not exist a large magnetic field leakage.
Charging speed is different: bidirectional fastCharging 18W is to use the support PD charging head to charge the charging treasure is fast, and the charging treasure is also fast to charge the mobile phone that supports PD, which is fast and saves time. The input is different: the output of the former is 10w, the input is not said, it may be 1A, that is, 5w, which is much slower, so the input size of different models of charging banks will also be different.
There is a difference, the output of the old charging bank is 5V1A, according to the maximum power calculation, its charging power can reach 5W. In contrast, the 18W fast charging device that supports the PD protocol has a maximum charging power of 18W. For mobile phones that support the PD fast charge protocol, enableSpecific application scenarios and requirements. Advantages of wireless charging: Convenience: Wireless charging does not need to plug in or pull out the charging cable, just put the device on the charger to start charging, very convenient. Aesthetic: Wireless charging will not damage the shell design of the device, making the overall device look more beautiful.
2, hello, of course, the flash charger is fast, VOOC flash charge: VOOC flash charge is the world's first mass-produced commercial fast charge scheme, compared with other fast charge schemes, the technical threshold is higher, VOOC flash charge requires a customized adapter and battery use. OPPO customized it specificallyThe adapter, battery, data cable, circuit, interface, and for this in-depth development of intelligent all-end five-level protection technology, security is impeccable. 3, in theory, although compared with the traditional slow charging is different, but the two ways have specific charging equipment and supporting batteries, so charging will not damage the battery. If you do not believe that you can go to see some of the online evaluation of fast charge and unlimited charging videos, it is enough to prove that the two ways will not affect the normal life of the mobile phone.
4, when charging, ensure that metal objects are far away from the charging board, metal objects may cause the charging boardIt's overheating. Ensure that credit cards or other magnetic objects are kept away from the charging pad to avoid the elimination of magnetic information. Keep the remote key away from the charging pad to prevent low key charge. In the choice of charger, because most of the Qi charging mobile phones support up to 10W wireless charging, it is equipped with a charging head that supports more than 10W.
5, convenience The main advantage of the wireless charger is its ease of use. There is no need to carry additional charging cables and plugs, just place the phone on the charger to start charging. This is undoubtedly a huge convenience for people who travel a lot or work outside the home. Charging efficiencyHigh modern wireless chargers usually have a fast charging function, and their charging efficiency is not inferior to that of wired charging. 6, obviously, there is still a gap in the charging efficiency of wireless chargers, and there is still room for further improvement in technology. Wired faster, although wireless charging is a very practical function, but only some users, wired charging faster, wireless charging more flexible, get rid of the bondage of the wire, pick up and put down, without alignment, you can quickly charge. Both sides have their advantages and disadvantages and can make up for each other.
