1, the wireless charging of Apple mobile phones uses the principle of electromagnetic induction. What is the principle of wireless charging for Apple mobile phones? The principle of wireless charging technology is actually the principle of electromagnetic induction. Children who have learned high school physics, I believe that everyone is very clear that electromagnetic waves have energy, can be obtained through the electromagnetic coil, and then the coil will form a current, and finally through the integration of the circuit can be charged.
2, Apple mobile phone has adopted the latest wireless charging technology, this technologyThe technique relies on the principle of inductive coupling, which transmits electrical energy through alternating magnetic fields generated between the coils. Magnetic resonance builds a bridge of energy transmission between the charger and the device, and the coil and capacitor work together to form resonance and realize wireless charging. While enjoying the convenience of wireless charging, users need to pay attention to some things. 3, the wireless charging technology of Apple mobile phone uses the principle of magnetic induction, through electromagnetic induction to transfer the current to the charging board and mobile phone, in this process, the electromagnetic field will produce a small heat to the radio components inside the mobile phone, but this heat is very small, not enough to cause damage to the battery.What is the difference between electric treasure? Which is better? '> What is the difference between wireless charging and wired charging bank? Which is better?
1, 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.
2, the charging speed is slightly slower than the wired charging bank, even if it has a fast charge, the charging speed of the wireless charging bank will be slightly slower, especially for devices with large capacity batteries, and the charging time is longer. Compatibility limitations: Wireless power bank requiredDevices support Qi or other wireless charging standards, and devices that do not support wireless charging technology cannot enjoy its convenience.
3, wireless charging and wired charging bank compared to what is 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.
1, 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.
2, although it is to charge smart phones and other devices, but the two still have 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 chargingFaster than the average product. Wireless charging treasure does not need interface support, as long as it supports wireless charging function can be used.
3, in the charging speed, wired fast charge is definitely more 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). <4, the difference: magnetic charging is wireless charging through electromagnetic field induction, usually charging power is below 20W, charging speed is slow. Wired charging treasure is the need to use a cable to charge the phone, usually charging power is generally more than 20W, charging speed is faster.
5, 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, no need to plug and unplug, but the speed is slower. Wireless chargers do not need wire transmission, and mobile phones need wireless chargingElectrical functions have become a trend, and the widespread use of wireless charging can make our mobile phone life more convenient.
6, after all, if the mobile phone does not support it, there is no way to use wired charging treasure, but it is better in charging fast, large capacity and good versatility. Of course, in my own experience, I often buy a wired power bank. On the one hand, the wired charging bank is faster, and on the other hand, the price is cheap, of course, the most important thing is that my mobile phone does not support wireless charging bank, and the prerequisite for using wireless charging bank is not met.
Because there are now relevant policies to limit the power of wireless charging, although it is in the stage of soliciting opinions, it may also affect the planning of the later manufacturers, the highest wireless charging rated power is 50W. And Xiaomi's 120W has not yet been mass produced and has been criticized, feeling very aggrieved. After all, the policy has not yet been implemented, and it is too early to speak.
Because milletThere is a catchphrase: hunger marketing. The so-called hunger marketing, used in the commercial promotion of goods or services, refers to the marketing strategy of commodity suppliers intentionally reducing production in order to regulate the relationship between supply and demand, create the "illusion" of short supply, maintain the product image and maintain the higher price and profit margin of goods.
After the cancellation of the charger in Apple 12 series mobile phones, domestic manufacturers have also set off a wave of cancellation of the charger, and now Huawei mobile phones are about to cancel the charger, but Huawei cancellation of the charger is conditional, that is, a price cut of 200 yuan to let consumers make their own choice, this approach is undoubtedly smart,With the previous millet mobile phone release with a charging version and no charging version is a plan with the same wisdom.
Huawei's response to the cancellation of the Huawei mobile phone with a charger, the official mall customer service has responded, so the lack of a mobile phone with a charger will reduce the recommended retail price of 200 yuan, consumers can choose the corresponding configuration according to their own needs, I think this is very conscientious, in addition to the price reduction, I also hope that this is a really useful thing for environmental protection.
To enable the wireless charging function of the Xiaomi phone, please follow the following steps: Confirm the wireless charging function of the phone: First, you needDetermine if your Xiaomi phone supports wireless charging. This can be confirmed by consulting the phone manual, visiting the Xiaomi website or through the phone's system Settings.
