3, wireless charging good. In wireless charging, the charger and the device to be charged do not need direct contact, easy to use, strong environmental adaptability, and avoid the physical interface, so there will be no interfaceWear, sparks, leakage and other problems, in addition to wireless charging can also achieve high voltage, high current, high power charging. The cable is charged. Wireless charging also requires a wired charger, but also more wireless charging board.
4, wired charging means that by connecting the power cord and the charger, the power is transmitted to the device for charging. Wireless charging is the transmission of electrical energy to the device for charging through electromagnetic induction or magnetic resonance technology. The following details the differences between the two charging methods. Advantages and disadvantages of wired charging and wireless charging Advantages and disadvantages of wired charging are fast charging speed, good stability, and data can also be carried out at the same timeTransmission.
5, Apple wireless earphone wireless charging and wired charging the difference is mainly: Apple wireless earphone wireless charging more than wired charging a wireless charging function, you need to equip yourself with wireless charger for charging; Apple wireless headphones Wireless charging and wired charging look slightly different.
6, wireless charging: the current charging standard Qi standard supports wireless fast charging is only their own wireless charger can be matched, do not need to worry about incompatible charging standards, charger quality is not good, after all, which mobile phone factory want to hit their own recruitment. But wireless is not without its drawbacks, because principle guidesAs a result, its conversion efficiency is inevitably inferior to that of wired charging.
1, cable charging is good. In the case of the same charging time, the power of the commonly used wired battery charger is 93% after charging, and the power of the wireless charger is 88% after charging. Obviously, there is still a gap in the charging efficiency of wireless chargers, and there is still room for further improvement in technology.
2, wireless charging is better. The convenience of wireless charging Wireless charging provides users with great convenience. Such asSome public places, such as cafes, restaurants and airports, provide wireless charging services, and users only need to put their mobile phones on the charging mat, without carrying additional charging cables. In addition, wireless charging technology is also being applied to furniture and cars, allowing users to charge at any time at home and in the car.
3, each has its own advantages. Different configurations, different charging methods, different colors. The current wireless charging basically uses electromagnetic induction technology, electromagnetic induction wireless charging is the essence of magnetic generation, and the principle of the transformer, the sending end and the receiving end have built-in coils, when the two ends are close, the sending end coil into the highFrequency alternating current will induce the same frequency of electromotive force at the receiving end, and then charge the receiving end after rectification and filtering.
Different. Moreover, according to different wireless charger manufacturers now, the current and frequency are not the same. (The students themselves bought one online, it is said that the speed is relatively fast. It is made by connecting the metal pole of the wireless charger receiving device purchased to the metal of the charging electrode of your own phoneOn the piece, then drag the wire outside and receive it from the outside. The heat is caused by the large current in the charger, which leads to obvious heat.
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.
The same output power case, the wireless charger is chargingThe device will have a loss during 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.
is different. Moreover, according to different wireless charger manufacturers now, the current and frequency are not the same. (The students themselves bought one online, it is said that the speed is relatively fast. The production method is to buy a wireless charger to receive the metal pole of the deviceAttach it to the charging electrode sheet of your own phone, then drag the wire outside and pick it up from the outside.) The heat is caused by the large current in the charger, which leads to obvious heat.
And in China, there are not many companies studying this technology direction, so you can see that domestic products are QI standard chips, which is undoubtedly the cost and design.The attraction of wireless charging is that it eliminates the hassle of plugging and unplugging cables, butIt is not. In the case of the Pixel 4, wireless charging takes 201 watt-hours (Wh) to fully charge, while wired charging only takes 126 watt-hours. This means that wireless charging not only consumes more time, but also comes with additional heat generation and power waste. Even when the wireless charger is idle, the charger that is not aligned with the phone or around it can consume power.
The loss of the battery is the same. First of all, wireless charging and wired charging have the same loss of battery. Because whether it is wired charging or wireless charging, it is necessary to stabilize the voltage of the electricity sent through the last step, butIt's just a different path. Wireless charging damage battery: Wireless charging in addition to the charge can not be directly supplied to the hardware, other aspects have no impact.
Wireless charging hurts the battery more than wired charging. As long as it is charged, it will cause damage to the battery, but wireless charging and wired charging are compared, wireless charging will cause more damage to the battery, because wireless charging will generate more heat, and the heat generated will cause more damage to the battery. Whether the line charge charges the battery is controlled by the internal circuit of the mobile phone, and the initial voltage for the normal operation of the internal control circuit of the mobile phone is provided by the battery.
Wireless charging hurts the battery more than wired charging. In fact, we all know that as long as it is charged, it will cause damage to the battery, but wireless charging and wired charging are compared, wireless charging will cause more damage to the battery, because wireless charging will generate more heat, and the heat generated will cause more damage to the battery.
