Today to share Jilin wireless charging chip good knowledge, which will also explain the wireless charging chip company ranking, if you happen to solve the problem you are now facing, don't forget to pay attention to the site, now start!
< ul>Durable: the power transmission element is not exposed, so it will not be eroded by moisture and oxygen in the air; There is no contact, so there is no loss caused by mechanical wear and flaring during connection and separation. Convenient: there is no need to connect with wires when charging, as long as it is placed near the charger, there is no need to occupy multiple power sockets, and there is no trouble of multiple wires winding each other. In theory, wireless charging technology is safe and harmless to the human body. The resonance principle used in wireless charging is magnetic resonance, which is transmitted only between coils resonating at the same frequency, and other devices cannot accept the band. In addition, the magnetic field used in wireless charging technology is itself harmless to the human body.
The harm is relatively small can be ignored, although wireless charging technology has appeared in the 19th century, but the popularity of mobile phone applications is not high. It uses the principle of "magnetic resonance" to allow the wireless charger to transmit an electric charge through the air to the phone's battery. Many wireless chargers on the marketNo radiation value is indicated, and electromagnetic radiation standards for wireless chargers have not yet been issued.
Slightly slower charging speed: Compared with wired charging treasure, even if it has fast charging, the charging speed of wireless charging treasure will be slightly slower, especially for devices with large-capacity batteries, and the charging time is longer. Compatibility limitations: Wireless charging bank requires the device to support Qi or other wireless charging standards, and does not support wirelessCharging technology devices do not enjoy its convenience.
Apple cable charge well. The advantage of the magnetic magnet is that it can be adsorbated near, and the adsorption can be charged. The charger is automatically aligned with the position of the charging coil, which solves the problem of manual alignment for traditional wireless charging. But it is still a wired form, and the power is not as good as wired charging, so the key moment or wired charging is more realistic. If the MagSafe magnetic charger wants to turn into a regular one, it will depend on when the iPhone removes the charging port.
Cable charging is good. In the case of the same charging time, the commonly used wired battery charger is chargedThe battery power is 93%, and 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.
The second kind of wireless charging, its working principle is the most used electromagnetic induction, wireless charging less line bondage, each charge on the go, compared with wired charging, it does not plug and unplug the data cable cumbersome, so charging is more safe, more fast, its disadvantage is that the charge is relatively slow.
Each has its own advantages: wireless charging is convenient, no need to connect the phone to the charger, put it on the charging board; wiredUsing alternating magnetic fields generated between coils to transmit electrical energy, inductive coupling technology will become a bridge connecting charging base stations and devices.
Protection interface: Cable charging requires frequent insertion and removal of the charging cable. Long-term use may cause damage or wear of the interface. Wireless charging eliminates this problem, and the phone interface can remain in good condition for a longer time, extending the service life of the phone. Low charging efficiency: Compared with wired charging, wireless charging is less efficient. That means it takes longer for users to fully charge.
Low efficiency: energy storage and transmission efficiency is not as good as real contact. Charging speedSlow: Due to low efficiency, the charging speed is slow at the same input power. High cost: The charger needs to have an electronic circuit to promote the wireless coil, and the electrical device needs to have an electronic device to change the power, both also need to have a wireless coil, so the cost is higher than the direct contact.
Disadvantages of mobile phone wireless charging Although the technical content of the equipment is high, the economic cost of the equipment is high and the maintenance cost is large. Because of the realization of long-distance high-power wireless magnetoelectric conversion, the energy consumption of the equipment is high. As the distance and power of wireless charging devices increase, the loss of idle work will be greater.
Wireless charger is good, convenient, safe and durable; The disadvantages are bondage, high price and low efficiency. Advantages of wireless charger: Convenient: wireless charging belongs to one-to-many charging, which solves the problem that the interface is not applicable, and also avoids the phenomenon of poor contact caused by repeated plugging and unplugging of the mobile phone interface, which can better protect the mobile phone interface.
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. advantageConvenience: Wireless charging of mobile phones eliminates the hassle 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.
Advantages: The advantage of wireless charger is that we can charge the phone at the same time, no longer need to unplug the data cable. In addition, it can be taken at any time, which is more convenient than charging with a data cable. At the same time, it can provide certain support for the phone, making the phone charge more stable. Cons: One downside to wireless chargers is chargingThe speed is relatively slow, and most wireless chargers only support 5W or 5W charging power.
After a period of hands-on experience, iWALK Magic Scorpion wireless charger is still good on the whole, with a good design and excellent performance, support 10W, 5W, 5W three different wireless output, and support active heat dissipation function. And the price of 100 yuan, also makes this wireless charger become quite considerable.
Purple meter wireless charger lists the compatible models of the product, and clearly indicates the use of IDT program, which can quickly charge devices such as iphones. attachmentIn terms of Xiaomi and purple rice are equipped with USB-C data cables (the bundled version of Xiaomi wireless charger does not contain data cables), but Purple rice wireless charger is also standard with an 18W fast charger.
