1, official expensive. The official wireless charging is quite expensive, but you go to a treasure search, big times, dozens of dollars, and there are many manufacturers of wireless charging, I think there is no need to buy hundreds of thousands of, buy dozens of try to feel on the line.
2, the use of wireless charger for Apple mobile phone is as follows: First, the wireless charger is inserted into the cigarette lighter socket or USB port of the vehicle. Then turn on your phoneBluetooth function and pair the phone with the charger. There are usually detailed operation steps in the instructions of the charger. Place the phone on the charger, make sure that the phone and the charger are tightly attached to the charging area, and start wireless charging.
3, the automobile wireless charging system is not only a power problem, but also an integrated system integrating communication, control, power, radio frequency and payment technical capabilities. Therefore, it is difficult to rely solely on automobile companies and wireless charging suppliers to unify, and the entire interest chain and supply chain are long, which is also a reason for failing to make wireless charging take shape.
4, the first use of wireless charging function to charge the Apple x, will not harm the battery, because wireless charging technology has been very mature, wireless charging principle is to use the built-in wireless charging function in the phone, only need to put the phone on the wireless charger can be charged. Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method uses induction.
5. Connect the charger to the power supply. Use the power adapter that comes with the accessory or the power adapter recommended by the manufacturer. Place the charger on a horizontal surface or other location suggested by the manufacturer. willWireless charging, also known as inductive charging, non-contact inductive charging, comes from wireless power transmission technology, is the use of near-field induction, that is, inductive coupling, 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.
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, in mobile phones, electric vehicles, smart furniture and other fields have appeared wireless charging expensive Products that support wireless charging. 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 system mainly adopts the principle of electromagnetic induction. Wireless charger refers to the charger that does not need to be connected to the terminal device that needs to be charged without the traditional charging power cord, using the latest wireless charging technology, through the use of the magnetic field generated between the coils, the magical transmission of electrical energy, inductive coupling technology will become the connection of the charging base station and the devicePrepare the bridge.
The basic principle of wireless charging is to convert the current into a magnetic field, which is transmitted through the air and then converted into a current to be transmitted to the intelligent terminal. 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 supply power to the system directly. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.
Price: Due to wireless charging requiredTo add an additional wireless charging module wireless charging is expensive , so its price is slightly higher than that of wired charging. In addition to the above points, wireless charging and wired charging are almost identical in their aspects, such as appearance, sound quality of headphones, noise reduction effect and so on.
The biggest difference between AirPods wired charging box and wireless charging box is whether to support wireless charging function, the wireless charging box indicator light is outside, the cable charging box refers toThe indicator light is inside. Second is the price, the wireless charging box is more expensive. In terms of the size and appearance of the charging box, the two are the same, without any difference.
Wired charging and wireless charging configuration Different wireless charging technology more advanced AirPods wired version of the charging box, like the first generation, can only use lightning data cable to charge, and the wireless charging version, is equipped with a charging box that supports wireless charging. As long as the charging box on the wireless charging board can be charged wireless charge expensive ; In addition, the wireless version of the price is more expensiveA little.
Abstract Is Wireless charging expensive : Mobile phone wireless charger is the need to buy additional wireless charging expensive mobile phone accessories wireless charging expensive , and its price is relatively high, the wireless charger on the market is cheap there are ten or twenty yuan a, but the better is generally 80 or 90 yuan to more than 100 yuan, Some cost hundreds of dollars,The specific price depends on the brand charging efficiency, compatibility standards, workmanship materials, modeling and other aspects.
Wireless charging price is too expensive, comparable to two mobile phone wireless charger is not cheap, take iPhone, wired charging only spend 148 yuan to buy a charger head, and wireless charging is not cheap, MagSafe charger price is 329, dual charger price is 1049. That's about the same price as some second phones.
Vertically place the mobile phone on the wireless charger to charge: Please first place the wireless charging pad on the tray of the wireless charger to increase the tray height.Then put the phone on the wireless charger to charge Wireless charge expensive ; Horizontal charging of the mobile phone on the wireless charger: The mobile phone can be directly placed on the wireless charger to charge without placing the wireless charging pad. If the wireless charging pad has been placed before, please remove it first and then charge it horizontally.
Reference price: 278 Charging protocol: PD charging method: Wireless Belkin This wireless charger is certified by QI wireless charging protocol, providing the largest 15W wireless fast charge, such as Android Huawei, Samsung and other mobile phones wireless fast charge, for AppleIt can only support 5W charging.
The answer is of course yes, it is Pinwin TS-C093 wireless charger, the price of 49 yuan is indeed close enough to the people, but through a period of use, the author's cognition of this product from the initial surprise quickly changed into "tasteless food, abandoned pity", why is it so wireless charge expensive? Please keep looking back.
1, charging power limited, charging technology between different brands is not interworking between the current mobile phone power update quickly, a day to increase a power, from the original 18W fast charge into a variety of fast charge power, 30W, 45W, 65W, and now there are 120W super fast charge power, This also leads to a lot of wireless charging boards in the current world, and if you choose the wrong one, you can not experience the full charging power.
2, because there is a heating problem in the electromagnetic conversion process, testConsidering the safety of electricity and other factors, so in 2021, China's Ministry of Industry and Information Technology issued a technical requirement for wireless charging equipment, which has a clear provision: wireless charging rated power shall not exceed 50W. In order to comply with this regulation, manufacturers have to control the power. This is also a reason for the gradual disappearance of wireless charging.
3, due to the heating problem in the electromagnetic conversion process, taking into account the safety of electricity and other factors, manufacturers have to control the power. This is also a reason for the gradual disappearance of wireless charging. After all, the cable fast charge has developed to 120W, and most mobile phones are equippedThe fast charge is more than 60W, which has surpassed the wireless fast charge, so wireless charging has gradually opened the gap with the wired fast charge because of the technical requirements of the equipment.
4, that is, the power of the universal charge is particularly large, many people who have used the universal charge know that their mobile phone battery is more and more charged, the more and less power is charged, originally full of 100% can be used for two hours, but to the back, it may only be used for half an hour.
5, currently does not support long-distance charging. In theory, wireless charging technology is safe and harmless to the human body, and wireless charging is the resonant source usedThe reason is that magnetic field resonance, only transmitted between coils resonating at the same frequency, and other devices cannot accept the band, wireless charging technology uses the magnetic field itself is harmless to the human body.
