Will wireless fast charging be slow?

Wireless fast charge is neither fast nor slow. Wireless fast charge is much faster than wireless fast charge, and slower than wired fast charge. The power that the charging head wired outputs to the wireless fast charge base is not the wireless fast charge output power but the wireless fast charge input power. Charging time is 2 hoursThe wireless fast charge is not as fast as the wired fast charge for 1 hour and 30 minutes, which is not a fast charge. Unexpectedly, the wireless fast charging efficiency of 60% when the 18W is charged for 2 and a half hours.

In general, the conversion efficiency of car wireless chargers is limited, but by choosing a reasonable charger, we can improve the situation. Although the speed of wireless fast charging is not fast, it is not too slow, and consumers should pay attention to the power and actual charging efficiency of the charger when purchasing.

Many people worry about the harm of electronic equipment to the human body, but in fact, this is not a need to worry, the closed magnetic field is very safe, will not dryInterference mobile phone signal, and low temperature fast charging function, charging will not heat. Of course, the most important thing is the charging effect, wireless charging although relatively slow, but the effect is still very stable.

Although some people worry that wireless fast charging will harm battery life, 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.

Slightly slower charging speed: compared with wired charging treasure, even with fast charging, wireless charging treasureThe charging speed is slightly slower, especially for devices with large capacity batteries, and the charging time is longer. Compatibility limitations: Wireless charging bank requires devices to support Qi or other wireless charging standards, and devices that do not support wireless charging technology cannot enjoy its convenience. In fact, it has to be said that the current wireless charger does have a lot of shortcomings, and in the actual use of the process, there is indeed a slow charging speed, wireless charger is relatively less embarrassing situation, it is precisely because of this, these technologies need to continue to improve, I believe that the future one day wireless router will become more and more convenient,But also can realize the true sense of wireless charging.

Pros and cons of mobile phone wireless charging

Convenience: Wireless charging of mobile phones eliminates the trouble of using charging cables. Users only need to place the phone on the charging dock, without plugging or unplugging the charging cable, to start charging. This makes the charging process easier and faster. Flexibility: Wireless charging eliminates the need for a specific charging cable. Users no longer need to carry and connect a specific type of charging cable, and can charge at any time on multiple charging docks that support wireless charging.

Mobile phone wireless chargingPros: Less wear and tear on Lightning cables On the other hand, the popularity of wireless charging for iphones will reduce cable usage. The wear on the cable will be reduced to almost zero.

Advantages: Convenience: Wireless charging eliminates the use of charging cables, and users only need to put the phone on the charger to achieve charging, eliminating the trouble of plugging and unplugging the charging cable. Beauty: Wireless charging makes the charging process of the mobile phone more tidy, without messy charging lines, which can improve the beauty of the mobile phone. Protection interface: Wireless charging can reduce the number of plug and unplug interface, reduce the risk of interface damage and wear,Extended mobile phone life.

The advantages and disadvantages of wireless charging

Advantages of wireless charging: one: reduce loss. As we all know, when using wireless charging, wireless charging efficiency , just connect the wireless charging board to the power supply first, and then place the device supporting wireless charging on the wireless charging board. Although wireless charging still needs to be connected to the power supply, it can reduce the use of data lines and avoid a large amount of loss and waste of data lines, which is relatively an environmentally friendly charging method. Two: high adaptation rate.

Mobile phone wireless charging has the advantages of convenience, flexibility, and protection interface, and the disadvantages are low charging efficiency, slow charging speed, and high cost. Benefits Convenience: Wireless charging of mobile phones eliminates wireless charging efficiency The trouble of using a charging cable. Users only need to place the phone on the charging dock, without plugging or unplugging the charging cable, to start charging. This makes the charging process easier and faster. Flexibility: Wireless charging eliminates the need for a specific charging cable.

The advantages of wireless charging are: reduce loss, high adaptation rate, the disadvantages are: the distance is too small, onlyTransition technology Wireless charging efficiency ; The benefits of wireless charging reduce the loss. As we all know, when using wireless charging, you only need to connect the wireless charging board to the power supply first, and then place the device that supports wireless charging on the wireless charging board.

The biggest advantage of wireless charging is convenience. Wireless charging has little impact on mobile phones, but when all electronic products support wireless charging, the convenience brought to users is more interesting. Apple says that future models of AirPods wireless headphones will use support AAlternating current generates a certain current in the receiving coil of the mobile phone through electromagnetic induction, thereby transferring the point energy from the originating end to the receiving end, and then starting to power the mobile phone from the charging seat. Magnetic resonance.

Electromagnetic induction: The fundamental principle is to use the principle of electromagnetic induction, similar to a transformer, the primary coil of a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, thereby transferring the energy from the transmission end to the receiving end. The conversion efficiency is high, the cost is cheap, but the transmission distance is short, and it is easy to be affected by the placement.

The basic principle of wireless charging is to convert the current into a magnetic field, magneticThe field is transmitted through the air and then converted into a current to be transmitted to the intelligent terminal. When the system works, the input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to supply power to the system directly. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.

Wireless charging system mainly adopts the principle of electromagnetic induction. Wireless charger refers to the charger that does not need to be connected to the terminal device that needs to be charged without the traditional charging power cord. It adopts the latest wireless charging technology and transmits electric energy magically by using the magnetic field generated between the coils.Inductive coupling technology will become a bridge connecting charging base stations and devices.
