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.
Wireless chargingThe electric 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 magic transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment.
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 uses the principle of electromagnetic induction, which operates at a very low frequency and does little harm. If you are still worried, you can choose a shielded scheme.

From the front, the front end of the base is equipped with LED indicators, and the support board is layered above and below, using different designs. Indicator light is green when working.
2, millet vertical air cooled wireless charger (55W black) 199 yuan currently millet maximum power (charging speed fastest) wireless charger, if the phone is 30W or 33W wireless charging power, then it is recommended that you "redundant" to buy this power of the wireless charger, because the mobile phone upgrade faster, and wireless charger this product can be used for several years, A new mobile phone can also achieve power coverage in the future.
3, compared with the common 10W wireless charging technology on the market, Xiaomi's 30W wireless flash charge can charge half of the 4000mAh battery in 25 minutes, achieving "wireless beyond.Wired "efficiency. Xiaomi's vertical air-cooled wireless charge 30W is cleverly designed with an ergonomic tilt, which is convenient for users to operate while charging, and the built-in ultra-quiet fan can effectively actively dissipate heat, improving the comfort of the charging process.
You can use a wireless charger to charge an iPhone by placing two phones close together and placing the back of one phone close to the back of the other phone. Expand your knowledge: The iPhone is Apple's (AAPL)Inc. on January 9, 2007 launched a series of mobile phones with the iOS operating system.
How to use wireless charging for iphones is as follows: Buy a wireless charger: You need to buy a wireless charger for iphones. You can choose from Apple official or third-party brands of wireless chargers. At the time of purchase, make sure that the charger supports Apple's wireless charging standard. Place the phone and charger: Place the iPhone in the charging area of the wireless charger, making sure that the phone is in good contact with the charger.
First get an iphone8.Get a wireless charger. Connect the wireless charger to the power supply. Place the iphone8 on the sensor area of the wireless charger. You can see the phone start charging and wait patiently for the charging to complete.
Confirm that your phone supports wireless charging model: If you are not sure whether your phone supports wireless charging, you can open the Settings app and select General About local. At the bottom of the page, you can see the device model. If your device model is one that supports wireless charging, then it will show a "Qi charging" after the model name, which means your device supports Qi
