It goes without saying that wireless charging is convenient. In addition, wireless charging is safer. Without exposed connectors, potential safety hazards such as leakage and running are completely avoided. Some people are worried about the problem of radiation. This technology was first used in water purifiers. It has been 8 years and its safety has been verified by 36 countries, and it will certainly not cause harm to humans and the environment. According to reports, wireless charging basically transmits energy through a magnetic field, and most humans and most objects around them are non-magnetic. Another advantage of wireless charging is that it saves electricity. The efficiency of wireless charging equipment is about 70%, which is equivalent to that of wired charging equipment, but it has the function of automatically shutting down when fully charged, avoiding unnecessary energy consumption. Moreover, the reception rate of this efficiency is continuously improving, and will soon reach 98%. Wireless charging devices are much "smarter" than ordinary chargers. For different electronic products, the power interface can automatically correspond. When charging is required, the transmitter and receiving chip will automatically start working at the same time. When fully charged, both parties will automatically shut down. It can also automatically identify different equipment and energy requirements, and perform ‘personalized work’, which is intelligence.

Now, for the safety of consumers and their convenience, relevant researchers have provided near-field wireless charging technology (that is, they need to be placed next to the transmitter). At the same time, they are also studying long-distance wireless charging, which will be a Emerging Markets. In fact, the current technology can achieve effective power transmission within a range of 3 feet to 4 feet, but this still needs to be verified by relevant organizations. I believe that in the next 5 to 10 years, or even faster, long-distance wireless charging will enter everyone's life.　　In the future, not only low-power appliances, but also common household appliances, medical equipment, power tools, office appliances, kitchen appliances, etc., can be wirelessly charged. In fact, it should be called "wireless power supply" to be precise, that is, while transmitting and using electric energy, there is no need for any power storage devices similar to batteries, and there is no need to charge in advance.

At that time, the wires, power strips, and batteries can all be gone, and you can't even feel the presence of electricity. It's like air, making you feel like it's in your hands.
