wireless charging in the end what is the situation, how to achieve wireless charging?

    Wireless charging is how it works, as the name suggests is not charging charging line. Similar to WiFi, it is very convenient. In theory, power can be supplied to mobile phones and other electronic devices anytime and anywhere. However, wireless charging is still not able to transmit as far away as WiFi, and now mature solutions can only achieve wireless charging within a distance of 10mm, generally a distance of about 3~5mm is better, and such wireless charging technology adopts Magnetic induction wireless charging technology. In 2015, it is estimated that there will be a number of new technical solutions that will be mass-produced, namely magnetic resonance wireless charging technology. It is expected that wireless charging can be realized in the range of about 125 px. With the maturity of technology, it is expected that in the next 2 to 3 years, the charging distance of wireless charging can reach around 10~750px, which can basically meet the charge requirements that are not bound by anytime and anywhere. To achieve wireless charging requires a transmitter and a receiver. The transmitter is a wireless charger and the receiver is a mobile phone. There is a coil at the transmitter and a coil at the receiver. The transmitting end transmits energy through the control board and the coil, and the receiving end receives energy through the control board and the coil, so that wireless charging can be realized. As shown below in the Samsung mobile phone and free charge technology wireless charging mobile power charging, the phone can be charged on the wireless charger, no need to connect through the USB port to charge.
