This article gives you a talk about wireless direct charge cutting, and how much rechargeable cutting price is the corresponding knowledge point, I hope to help you, don't forget to collect this site. < / p > < h2 > the article directory list: < / h2 > < ul > < li style = 'margin - bottom: 3 px; list-style: none'>1, How does wireless charging work for mobile phones?
Wireless charging, also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, it is not necessary to transmit electricity to the device like the traditional wired charger, but the device that needs to be charged can be charged by contacting the wireless charging base.

The principle of wireless charging technology is "magnetic electricity", simply put, through the charging device and the mobile phone device installed on the two "magnetic equipment" mutual induction and formation of current. At present, products supporting wireless charging have appeared in mobile phones, electric vehicles, smart furniture and other fields. Among them, in the mobile phone industry, the "Qi standard" is the most common, and Qi labels are often used in the packaging of many mobile phones and wireless chargers.
Wireless charging is also known as inductive charging or non-connectionTouch induction charging, based on the principle of electromagnetic induction, does not require transmission cables to transmit electricity to the device like traditional wired chargers, but the device that needs to be charged can be charged by contacting the wireless charging base.
Basic principle: The use of electromagnetic induction, that is, the primary coil of a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, so as to transfer energy from the transmission end to the receiving end.
Philips: Philips is one of the world's largest electronics companies,Its hair clippers are known for their innovative technology and durability. Philips' hair clippers are suitable for both home and business trips, can adjust the power for different hair types, and have trim combs for children and adults. Panasonic: As one of the world's top 500 brands, Panasonic's new electric hair clippers are equipped with precision razor heads and are loved by consumers.
Fei Ke recommended model: FC5908 Recommended reasons: This hair clipper quality is reliable, the knife head is ceramic, it is very easy to use, can adjust various specifications, the difficulty of getting started is basically zero, the knife head is sharp, the whole body is washed, easy to clean, suitable for barber white use.
In the hair clipper electric clipper brand, Philips, Wahl and Panasonic are very good choices, they also enjoy a high reputation in the industry. Philips: Philips is a leading health technology company whose product line includes a wide range of hair clippers. Philip's hair clippers are loved by consumers for their exquisite craftsmanship, excellent performance and reasonable price.
3, so if the way of wireless charging does not change, it is difficult to increase this type of user, not to mention the fire.
4. Yes. First of all, from the macro analysis, according to market research data, in 2018, the scale of wireless charging transmitter and receiver can reach $500 million and $1.6 billion, respectively.When the current of the power supply passes through the coil (the power supply coil of the wireless charger), a magnetic field will be generated, and other unenergized coils (the electric coil of the mobile phone) will generate current near the magnetic field to charge the mobile phone. As shown below.

5, mobile phone wireless charging technology is completely without the use of wires, the use of magnets for mobile phone charging technology. Mobile phone wireless charging technology, derived from wireless power transmission technology, uses magnetic resonance to transmit charge in the air between the charger and the mobile phone, and the coil and capacitor form resonance between the charger and the mobile phone to achieve electricityTechnology for efficient transmission.
Apple mobile phone general we are better to use direct charging, its charging effect is also a direct point, wireless charging is now a relatively novel way, but I still accept wired charging is better. I always feel that the money will charge the efficiency of the battery will be higher. The iPhone12 can be charged wirelessly or via wired.
Apple straight. Direct charge that can charge fast, but also can play at the same time, wireless charging time is longSlow charging, wireless charging at night when you are not using your phone. However, the conversion efficiency is best at about 80%, and the remaining electrical energy can only be converted into heat, so the heat of wireless charging has been a big problem. High-power wireless chargers also need to be paired with active cooling fans.
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. ifIf the MagSafe magnetic charger wants to become normal, it depends on when the iPhone removes the charging port.
Apple straight. Direct charge can be charged fast, but also can play at the same time, wireless charging time is long and slow, and wireless charging can be done at night when the mobile phone is not used. The iPhone uses lithium-ion batteries, which have the advantages of fast charging, long lasting use, higher power density and the ability to provide longer battery life in a lighter volume.
This is the end of the introduction of the price of wireless direct charge shear and charging shear, I don't know where you find what you needDid you get the information? If you want to know more about this, remember to follow this site. < / p >
