Each has its own advantages: wireless charging is convenient, no need to connect the phone to the charger, put it on the charging board; Wired charging is more stable, and the charging speed is faster than wireless charging.
Wireless charging and wired charging each have advantages, which is better depending 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 shell design of the device, so that the device is integratedThe body looks more beautiful.
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.
Compared to wired charging, wireless charging has less impact on the environment. Wired charging equipment generates a lot of electronic waste in the production and disposal process, while wireless charging equipment is produced and processedThe process is relatively environmentally friendly. In addition, wireless charging can also reduce the use of cables and adapters, thus reducing the consumption of natural resources. Wireless charging compatibility and scalability Wireless charging technology has good compatibility and scalability.
Wireless charging Wireless charging applications are gradually expanding, such as mobile phones, watches and even electric cars. The principle is to transfer energy through an electromagnetic coupling between two coils. The advantage of wireless charging is that it is flexible to use and avoids interface problems, but the test technology needs to be perfected, especially in terms of power conversion efficiency.
Low efficiency. Current wireless chargingThe technology is not mature, many problems have not been solved, energy storage and delivery efficiency is not as good as wired charging; Charging speed is slow. Due to low efficiency, the charging speed is slow under the same input power; The cost is high. Wireless charging has high technical content, consumes more manpower and material resources, and the corresponding manufacturing cost is also relatively high; Low compatibility.
The disadvantages of wireless charging are: low efficiency: the efficiency of energy storage and transmission is less than real contact. Slow charging speed: Due to low efficiency, the charging speed is slow at the same input power. Wireless charging althoughYou can leave the cable unplugged, but the distance between the phone and the charger, although small. However, the electromagnetic energy loss is still not small, and the power received by the general mobile phone is about 75% of the power sent by the charger.
Bad two: battery loss. Relative to wired charging, because the heat generated during wireless charging will be relatively high, wireless charging will actually have a slightly larger loss to the battery.
Harm: Wireless charging causes environmental harm. Let's first discuss the disadvantages of wireless charging, because it is very important. Wireless charging pads are inefficient, and depending on the design and the position of the user's phone on the charging pad,Charging efficiency can range from 30% to 80%. This means that, even under ideal conditions, 20% of the electricity is wasted.
Disadvantages Low charging efficiency: compared with wired charging, wireless charging efficiency is low. 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.
2, each has its own advantages: wireless charging is convenient, do not need to connect the phone to the charger, put on the charging board; Wired charging is more stable, and the charging speed is faster than wireless charging.
3, wireless charging and wired charging bank comparedWhat's the difference? Although both are used to charge devices such as smartphones, there are some differences. Simply put, wireless charging is more convenient, does not require wire entanglement, can remove the trouble of wire; The wired charging treasure is faster in charging speed, such as the Secretary-General is a wired charging treasure, which supports PD two-way fast charging, and the charging speed is faster than the general product.
4, the biggest difference is that the charging method is not the same. The traditional charging bank charges the mobile phone, basically through the wire transmission, charging speed is faster; When charging a mobile phone, the wireless charger does not need to plug and unplug the cable, but the speed is moreSlow. Wireless chargers do not need wire transmission, mobile phones need wireless charging function has become a trend, the wide use of wireless charging can make our mobile phone life more convenient.
5, the conductivity is different, the use of different. Wireless charging treasure usually uses the principle of electromagnetic induction to charge, in which the coil is usually copper wire. Copper wire has good electrical conductivity and can effectively transmit electrical energy. The wired charging bank uses a traditional charging cable, and the conductor is often copper wire to ensure low resistance and high conductivity.
6, in the charging speed, wired fast chargeIt's definitely better than wireless fast charge. From the data point of view, the current wired charging has reached the highest 50W mass production charging, Huawei 40W fast charge compared to OPPO 50W fast charge, and the fast charge power of other mobile phone manufacturers is basically more than 18W. Even Apple, the slowest charging smartphone, also supports PD fast charging. Recently, Xiaomi and vivo have more than 100W of super charging power (not yet mass-produced).
