Is there a wireless power bank? In 2019, the answer is obviously yes, although there are not many wireless charging products in the real sense on the market, but the overall technology has been relatively mature. The principle of wireless charging treasure is also mainly wireless transmission, freeRemove the winding of the wire.
Wireless charging treasure is not any mobile phone can be used, because some mobile phones do not have wireless charging function. Wireless mobile power refers to devices and devices with built-in batteries that obtain power through wireless induction for charging.
Wireless charging treasure is the most advanced technology in the world, rich in micro-volume, large current, micro-temperature rise, metal resistance, no misaction and other advanced technical indicators, only it can set many essence in one and successfully built into the battery, can easily turn a variety of different brands of mobile phones into wireless charging mobile phones. It is mainly to be made public laterOccasions can use those wireless charging facilities.
Truly achieve wireless charging. iWALK Wireless Charger: 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. It adopts the latest wireless charging technology and transmits electric energy by using the alternating magnetic field generated between the coils. Inductive coupling technology will become the bridge connecting the charging base station and the device.
Wireless charging bank charging iPhone method is as follows: iPhone already has wireless charging function, just put the back of the phone on the wireless charging bank can be wireless charging areaStart charging. The iPhone does not have a built-in wireless charging function, so it needs to be achieved through the attached ring charging sticker. First, find the insertion port on the ring patch and plug it into the flash port of the phone.
2, should be OK, but this is not good for the phone, so I suggest you still use the phone's original charger.
3. After the wireless charger is powered, place the phone screen facing up directly in the center of the charger or the position suggested by the manufacturer to charge.
Principle of wireless charging: electromagnetic induction. The charging base and the mobile phone terminal have built-in coils, and when the two are close, the coil is based on oneThe constant frequency alternating current generates a certain current in the receiving coil of the mobile phone through electromagnetic induction, thereby transferring the point energy from the originating end to the receiving end, and then starting to supply power to the mobile phone from the charging seat. Magnetic resonance.
Electromagnetic induction: The fundamental principle is to use the principle of electromagnetic induction, similar to a transformer, the primary coil of a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, thereby transferring the energy from the transmission end to the receiving end. The conversion efficiency is high, the cost is cheap, but the transmission distance is short, and it is easy to be affected by the placement.
The basic principle of wireless charging is to convert the current intoThe magnetic field 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 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, by using the magnetic field generated between the coils, magical transmission
