The mystery of wireless charging: The exploration of electromagnetic induction and magnetic resonance With the rapid development of science and technology, wireless charging has penetrated into our daily life, from consumer electronics to industrial equipment, and even the automotive field, it is quietly changing our use experience. This article will delve into two mainstream wireless charging technologies: electromagnetic induction and magnetic resonance, to give you a deeper understanding of this convenient way to transfer power.
Now, let's explore the secrets of these two technologies!Power wireless charging usually uses a resonant mode by the power supply device (charger) to transmit energy to the power device, the device uses the received energy to charge the battery, and at the same time for its own operation.
2, restart the iPhone If the iPhone wireless charging suddenly does not charge, it may be because sometimes the iOS system update unpredictable errors will cause problems with the wireless charging function, usually as long as the restart can be solved. Remove the iPhone protective case Sometimes the iPhone protective case is too thick will also lead to wireless charging, then you can try the iPRemove the hone case and put it back on the wireless charging pad for charging.
3, if it can be used, it is OK, which is an electromagnetic conversion coil, not scratch the coil will not affect the charging effect. Cut off can not charge, short circuit will overload or even harm the charging head.
1, the charging speed is slightly slower: compared with the wired charging bank, even if it has a fast charge, the charging speed of the wireless charging bank is very lowA little slower, especially for devices with large capacity batteries, the charging time is longer. Compatibility limitations: Wireless charging bank requires devices to support Qi or other wireless charging standards, and devices that do not support wireless charging technology cannot enjoy its convenience.
2, 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 MagSafe magnetIf the charger wants to become normal, it depends on when the iPhone cancels the charging port.
3, the second kind of wireless charging, its working principle is the most used electromagnetic induction, wireless charging less line bondage, each charge with the release, 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.
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; Wireless charger to charge the phone, do not need wire noI use a plug and unplug, but it's slower. 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.
1, below, I will introduce a few good reputation of the charging treasure brand, for your reference. Xiaomi Charging treasure Xiaomi Charging treasure is a very popular charging treasure, its appearance is simple and stylish, durable, and charging speed is very fast. The Xiaomi power Bank also has multiple security protection functionsSuch as overcharge protection, overdischarge protection, short circuit protection, etc., to ensure the safety of users.
2, BYsi - Recommended model: M29 - Capacity: 20000mAh - Recommended reason: BYsi is a trustworthy brand, this charging bank supports multiple devices charging at the same time, large capacity and portable. Its multi-functional interface can charge a variety of devices, including iPad and mobile phones, whether it is Apple data cable or Type-C data cable can be used, very practical.
3, charging treasure durable good quality brands including South Carolina wireless charging treasure, purple meters 10 mobile electricitySource, Rome Shi WL1A wireless charging treasure, millet mobile power 3, etc., these are the best cost-effective brands in their respective fields, including wireless charging and wired charging, the advantage of wireless charging is that charging does not require the convenience of charging lines, each has its own advantages.
4, the first place: Pinsheng PISEN for many years focused on mobile power, digital 3C accessories, cloud routing and other intelligent mobile peripheral equipment O2O Internet enterprises, its products have been trusted by consumers, charging treasure has been Pinsheng proud work.
5, Millet charging treasure Millet charging treasure large capacity, fast charging! 50W fast charge is real fragrance! 20000 mah is big enough, you can give the mobile phone fast charge, you can also give the computer emergency charge! Very good, the evaluation is also good, the price is close to the people, the texture is good.
2, cable charging. 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, the pursuit of higher portability and comfort, you can choose wireless charging; In pursuit of faster charging speed and wider application range, you can choose wired charging. There is noThe advantage of line charging is that it provides higher portability, which is especially suitable for wearable devices, smart home and other fields. However, the charging speed of wireless charging is relatively slow, and the distance between the charger and the device will affect the charging effect.
