Difference 3, convenience: when the phone is charging, the phone comes in, but it is not convenient to answer in some specific situations. At this time, the convenience of wireless chargers is reflected. Simply pick up the charging case and move it to any place where the user can easily answer the phone.
Wireless charging and wired charging each have advantages, which is better to choose depends on the specificUsage 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.
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.
Wireless charging is 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.
Bound: Wireless charging needs to be adsorbed on the charging base, and can not be moved at will, which is more restrictive to the user than the wired charge. High price: The principle of wireless charging is different, resulting in the cost of wireless chargers is usually higher than that of wired chargers. The effectThere is no need to plug and unplug the charging cable frequently, so the data interface wear of the phone will be reduced a lot. At the same time, the coil of wireless charging of the mobile phone is not exposed to the air, which can also reduce the oxidative corrosion of the charging unit. The wired charging is often inserted and removed easily lead to wear, and the interface is exposed, which is easy to oxidation corrosion. Although wireless charging has many advantages, it is also found that there are many disadvantages in the actual use process.
Higher cost Compared with wired charging technology, magnetic resonance wireless charging technology related equipment costs and installation and maintenance costs are higher, which is also a limiting factor for its popularity.
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.
Advantages and disadvantages of wired charging and wireless charging The advantages of wired charging are fast charging speed, good stability, and data transmission can also be carried out at the same time. The disadvantage is that the connection line is required and the use is not convenient enough. There is noThe advantage of wire charging is that it is easy to use, does not need to connect the 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.
Slow charging speed: Since the Samsung Note 7 explosion, mobile phone wireless charging power has been castrated by manufacturers. Apple for the first time in the iPhone 8 series of mobile phones with wireless charging, but the charging power is only 5W. In contrast, the wireless charging power of Samsung mobile phones, although larger, is only 15W. Small charging power means charging speedIt will slow down.
HelloThe wireless charger must first load the mobile phone into the charging protective shell, and then the protective cover is placed on the induction base, and then the induction base is connected to the power plug, and the power plug is plugged in. Connect peripherals The mobile phone connects peripherals in wireless charging mode, one is to take out the mobile phone loaded into the charging protection case, the second is to connect Mini USB, and finally the Mini USB connects to the peripheral.
The difference between airpods wireless charging box and wired is: different charging methods: wired charging only supports connecting lightning data cable chargingWireless charging is equipped with a charging box with Qi wireless charging function, and wireless charging can be achieved by placing the charging box on the wireless charging board; The indicator position is different: the indicator position of the wireless charging box is outside, and the indicator position of the wired charging box is inside.
