Wireless charging devices are "smarter" than ordinary chargers. For different electronic products, the power interface can automatically correspond. When charging is required, the transmitter and receiver chips will automatically start working at the same time. When they are fully charged, the two parties will automatically shut down. It can also automatically identify different devices and energy requirements for ‘personalized work’. This is intelligence.
Now, for the sake of consumers' safety and their convenience, relevant researchers provide the near-field wireless charging technology (ie, need to be placed next to the transmitter). At the same time, they are also studying long-distance wireless charging. It will be a Emerging Markets. In fact, today's technology can achieve effective power transmission in the range of 3 feet to 4 feet, but this also needs to be verified by relevant organizations. I believe that in the next 5 to 10 years, even faster, long-distance wireless charging will enter everyone's life.
