1, wireless charging good. In wireless charging, the charger and the charged device do not need direct contact, easy to use, strong environmental adaptability, avoiding the physical interface, so there will be no interface wear, sparks, leakage and other problems, in addition, 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.
2, cableCharge it. 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.
3, wireless charging and wired charging have their own advantages, the choice of which is better depends on the specific use scenario and needs. 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. Aesthetics: Wireless charging will not damage the outside of the deviceThe shell design makes the whole equipment look more beautiful.
4, often use wireless charging has no effect on the phone battery. Wireless charging and wired charging effect is the same, but the wireless charging time is relatively longer, no impact on the phone. Wireless charging is the use of electromagnetic induction principle, through the coil coupling to achieve the transfer of energy. Wireless charging technology of mobile phone is a kind of circuit which is converted into charging circuit through transmitting circuit through power management module.
5, the advantages and disadvantages of wired charging and wireless charging The advantages of wired charging is fast charging speed, good stability, but also at the same time for data transmissionLose. The disadvantage is that the connection line is required and the use is not convenient enough. The advantage of wireless charging is that it is easy to use, does not require a cable, and only needs to put the device on the charging base to charge. The disadvantage is that the charging speed is slow, the charging efficiency is also low, and the device needs to be placed on the charging base, which is not flexible enough.
6, the efficiency of wireless charging is lower, and the charging time is longer, which may lead to an increase in user waiting time. Charging distance limit: Wireless charging requires a certain distance between the phone and the charger, if the distance is too far or there are obstacles, the charging effect may be affected. Price and compatibility: Wireless chargingDevices are often more expensive than wired chargers, and different brands of wireless chargers may not be compatible, requiring users to purchase an adapter or charger.
Recharge method is different, the amount received is different. Recharge methods are different: Flash Krypton direct charge is directly in the game or the official website for recharge, and substitute charge is through a third-party platform for recharge. The amount to the account is different: flash krypton direct charge is how much to recharge, how much to the account, and there will be a discount.
In summary, the main difference between direct charging and replacement charging is the charging sideType and process. Direct charging is the direct use of charging equipment to charge batteries or other devices, with the advantages of fast charging speed and high efficiency; Substitute charging is the charging of batteries or other devices through third-party devices or services, which has the advantages of portability and flexibility. When choosing direct charge or substitute charge, it is necessary to make a decision according to the specific charging needs and scenarios.
Different modes of operation: direct charging directly through the interface function of the platform, obtain the authorization code of the recharge card, and then automatically complete the recharge and feedback the result to the user; Replacement charging is carried out through the third platform, the process is relatively complicated, and users need to provide their own recharge cardsWill it be faster than wired?
The efficiency of wireless charging is lower than that of wired charging, but in the future, with the rapid progress of wireless charging technology, it is likely to be better than wired charging in charging efficiency. However, at present, the technology of wireless charging is not advanced enough, so the charging efficiency of wireless charging technology is lower than that of wired charging. At this stage, wireless charging is more as a supplement and auxiliary to wired charging.
Wireless fast charge is neither fast nor slow. Wireless fast charge is much faster than wireless fast charge, and slower than wired fast charge. Charging head wired output toThe power of the wireless fast charge base is not the output power of the wireless fast charge but the input power of the wireless fast charge. Charging time of more than 2 hours of wireless fast charge, not as fast as the wired fast charge of 1 hour and 30 minutes, is not fast charge. Unexpectedly, the wireless fast charging efficiency of 60% when the 18W is charged for 2 and a half hours.
Modern wireless chargers usually have a fast charging function, and their charging efficiency is not inferior to that of wired charging. At the same time, wireless chargers can also adapt to different equipment needs to meet the charging needs of a variety of devices. This can be very beneficial for multi-device users. Improve aesthetics and use spaceThe use of wireless chargers can greatly simplify the space of the home or office, avoid the mess of wires, and make the environment more tidy and beautiful.
Low charging efficiency: Compared with wired charging, wireless charging is less efficient. That means it takes longer for users to fully charge. In addition, since wireless charging requires energy conversion between transmit and receive, it may lead to reduced battery life. Slow charging speed: Due to the low efficiency of wireless charging, the charging speed is relatively slow. This causes users to have to wait longer to complete the charge.
Different, wireless 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.
Conclusion: Wireless chargers do produce electromagnetic radiation, although the numerical passUsually small, but should be wary of its possible cumulative effect. With the popularity of wireless charging technology, users are exposed to more and more radiation sources in daily life, such as mobile phones, computers, WiFi, etc., and long-term accumulation may have an impact on health. Wireless Charging Technology and controversy With the development of mobile Internet, the rise of wireless charging function has led to a discussion on electromagnetic radiation.
For the human body: wireless charging technology is safe and harmless to the human body. The resonance principle used by wireless charging is magnetic field resonance, which is transmitted only between coils resonating at the same frequency, and other devices cannot accept the band, in addition, wireless chargingThe magnetic fields used by the technology are inherently harmless to humans.
In fact, it is certain to tell you that the harm of wireless charging to the human body is very small, almost negligible. This is like the Wi-Fi, mobile phones, TVS and other electronic products we usually use, and we do not exist between the transmitter and the receiver the radiation level is small, and the main frequency absorbed by the human body is inconsistent with the charging frequency, so we can not worry about the harm of wireless charging.
With the development of mobile phone technology, wireless charging has become popular, and there are rumors that wireless charging is this "air separation charge.The radiation produced by "electric" technology is extremely strong and harmful to health. Truth: Wireless charging technology according to the technical principle, can be divided into three categories, namely electromagnetic induction, magnetic resonance and radio wave. The staff of the Communications Department of the Ministry of Industry and Information Technology said that it is inevitable that the wireless charger has radiation, but since it has been listed, it means that it must meet international standards and will not cause great harm to the human body. For this view, He Guili, director of the Tel Laboratory of the Telecommunication Research Institute of the Ministry of Industry and Information Technology, agreed: "Wireless chargers as long as they are done in accordance with technical specifications, there will be no radiation harm to the human body." But there is a key problem.
Does wireless charging technology radiate the human body? Does it cause cancer? Tests have proved that wireless chargers can indeed produce electromagnetic radiation, but the value is relatively small. Now users are exposed to more and more radiation: computers, tablets, mobile phones, WiFi, televisions, microwave ovens... The cumulative radiation value is very high, and if the user lives in such a high radiation environment for a long time, it may cause serious harm to the body and mind.
Low charging efficiency, battery loss. Low charging efficiency: wireless charging technologyIt can reduce the use of data cables, and its charging efficiency is lower than that of wired charging. Battery loss: The heat generated during wireless charging will cause a large battery loss. Wireless charging requires converting energy into a magnetic field and converting the magnetic field into an electric current to charge the battery, a process that generates additional heat.
Huawei wireless charging damaged battery. Whether it is wireless charging or wired charging charging for a long time will hurt the battery, but compared with wireless charging and wired charging, because wireless charging will generate more heat in the process of charging, high temperature is not good for the battery, so wireless charging more damage to the battery. However, when using wireless charging, pay attention to ventilation.
The disadvantage of wireless charging is that most of the efficiency of wireless charging is relatively low. Because relying on electromagnetic induction to charge, often the speed is relatively slow, and sometimes the phone needs to be quickly filled, then it is obvious that wireless charging is not as fast as directly using the phone to charge the data line.
