1, expensive wireless charging quality is better, cheap wireless charging quality is not good, this is the difference between them, generally the more expensive wireless charging years will be longer in the future.
2, the difference between airpods wireless and wired The difference between AirPods wireless charging version and wired charging version, there is and only the difference between the charging box. The wired charging version of the charging box is the same as the first generation, only supporting the connection of lightning data cable charging. While wirelessThe charging version, equipped with a charging case that supports wireless charging, can be easily charged by simply placing it on the wireless charging pad.
3, bound: wireless charging needs to be adsorbed on the charging base, can not be moved at will, the user is more bound than wired charging. High price: The principle of wireless charging is different, resulting in the cost of wireless chargers is usually higher than that of wired chargers. Low efficiency: Due to the low efficiency of wireless charging, under the same input power, the charging speed is slower than the line charging, especially the fast charging function of some brands.
4, higher price: compared with wired charging treasure,Wireless is usually more expensive and can be a bit of a budget challenge. It's no surprise that a good wireless charger is two or three times more valuable than a wired one. Advantages and disadvantages of wired charging treasure: Advantages: super fast charging: Wired charging treasure directly connected to the device through the charging line, can provide higher power charging, generally support fast charging, charging speed is fast, especially suitable for urgent charging. 5, wireless charging price is too expensive, comparable to two mobile phone wireless charger is not cheap, take the iPhone, wired charging only spend 148 yuan to buy a charger head, and wireless charging is not cheap, MagSThe price of the afe charger is 329, and the price of the dual charger is 1049. That's about the same price as some second phones.
Electromagnetic induction: Simple and efficient intimate contact electromagnetic induction, like a pair of tacit dancers, the sending end and the receiving end transfer power through induction magnetic flux. It is known for its simple structure, high efficiency and low cost, and is especially suitable for close-range device charging. However, it also has limitations, limited transmission distance and strict location requirements, needCharge only when it is accurately aligned, as shown in Figure 4-1.
Wireless charging is what is going on, as the name suggests is charging do not plug the cable. Similar to WiFi, it is very convenient. In theory, mobile phones and other electronic devices can be powered anytime, anywhere. However, wireless charging can not be transmitted as far as WiFi for the time being, and now mature solutions can only achieve wireless charging within a distance of 10mm, generally a distance of about 3~5mm is better, such wireless charging technology uses magnetic induction wireless charging technology.
Principle of wireless charging The principle of wireless charging is through electricityMagnetic induction, or electromagnetic radiation, transmits energy to a device that needs to be charged. Specifically, wireless charging is divided into two ways: electromagnetic induction and electromagnetic radiation. Electromagnetic induction: Through the principle of electromagnetic induction, the current at the transmitting end is converted into a magnetic field, and then the energy is transferred to the receiving end through the magnetic field, and then the energy is converted into current, so as to achieve wireless charging.
Mobile phone wireless charging system mainly adopts the principle of electromagnetic induction, energy coupling through the coil to achieve energy transfer. When the system works, the input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to the systemOpen wireless reverse charging method: You can enter the phone Settings -- battery -- more Settings -- open the "wireless reverse charging", after opening the peripherals can provide up to 10W charging power supply urgent charging. Note: After opening this function, if there is no good wireless charge and cheap wireless charge for a long time, the charging of his device will be automatically turned off; This function cannot be enabled when the battery life of the phone is less than or equal to 15%.
Connect the standard charger and data cable of the mobile phone to the wireless charger, and then put the mobile phone on the left and right of the wireless charger baseIn the middle position, wireless charging can be realized, the indicator light will have a breathing effect, and it will be extinguished after 5 seconds, plug and play, convenient and quick.
If you use vivo mobile phone, wireless charging is also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, it is not necessary to transfer 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.
Operating phone: vivox90 Operating system: OriginOS3The methods for enabling VIvox90 wireless charging are as follows: First, go to the phone Settings selectionItem. Then find the battery in the Settings screen. Then find the charging Settings in the picture. Finally slide down to find and turn on wireless reverse charging. The principle of wireless charging: The wireless charging system mainly adopts the principle of electromagnetic induction, and realizes the energy transfer through the energy coupling of the coil.
The wireless charging function of vivo mobile phone can be turned on by the following steps: First, ensure that vivo mobile phone supports wireless charging function. Some of vivo's older phones may not support wireless charging, so you need to first confirm whether the phone model supports wireless charging. Find the Settings icon on your phone and tap to enter the Settings fieldNoodles. In the Settings screen, find the "Battery" option and tap to go to Battery Settings.
Models that support this function can enter the phone Settings - battery - charging Settings - open the "wireless reverse charging", after opening the peripheral can provide up to 10W charging power supply urgent charging. Note: After this function is enabled, if there is no charging for other devices for a long time, it will automatically turn off; This function cannot be enabled when the battery life of the phone is less than or equal to 15%.
