Compared with the traditional wired charger desktop supporting wireless charging , the advantages of wireless charging desktop supporting wireless charging are obviousIn addition to eliminating the trouble of carrying data lines, it also prevents certain security risks caused by the leakage of the usual pin. Wireless charging technology is no longer new, Apple, Huawei, oppo and other mobile phone brands have been committed to continuous research and development.
Improve the comfort and durability of the device Wireless charging avoids the problem of interface wear caused by frequent insertion and removal of charging cables, and reduces the risk of loosening and damage caused by loose cables. At the same time, wireless charging usually has overheating protection, voltage and current stability and other functions, which can better protect the battery of the device and extend the service life of the device.
Get rid of cable shackles, simplify charging actions, and bring a more convenient charging experience. It can be used at home or in the office. Let's take a look at the correct use of desktop wireless charging.
Wireless charging has the advantage that you can abandon the complicated data line, so that the desktop becomes moreYuan, cost-effective can be said to crush the market similar 99 yuan products. In order to understand the workmanship of this product, the next thing to bring you is its unpacking.
A new powerful and stable wireless charger, hidden under the desktop, through the desktop to charge mobile devices. - Extremely stable charge before full chargeNo power outages. The future of charging A new and powerful wireless charger is hidden under the desktop to charge mobile devices through the desktop. The device input is 19V / 2A, and the charging distance can reach 45mm, while the traditional Qi charging distance is only 2-8mm.
The basic principle of wireless charging: electromagnetic induction: a certain frequency of alternating current in the primary coil generates a certain current in the secondary coil through electromagnetic induction, thereby transferring energy from the transmission end to the receiving end.
Wireless charger working principle: using the principle of electromagnetic induction, through the lineEnergy coupling is carried out to realize 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 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 charger using radio wave transmission, radio wave is not only a kind of electromagnetic wave, its own can also transmit energy, and can penetrate the air, so that wireless power transmission is possible.
