The Future of Wireless Charging

Over these short decades, the most common use of the telephone and the Internet has gradually become wireless. Now, the traditional wired charging model has become a thing in the past and wireless charging is opening the door to a new century. Although wireless charging is still in its early stages, the technology is expected to grow beyond expectation in the coming years. In this blog post, we’ll explore the basics of how wireless charging works, its advantages, and the future trends.

Today, there are three types of wireless charging technologies: radio charging, inductive charging, and resonant charging. Radio charging uses a miniature battery and a very low power consumption device which allows it to consume very little power. Devices that use this technology employ radio frequency waves to send and receive wireless signals. The principle of wireless charging is that the receiver is set to the same frequency as the transmitter. This technology is commonly used in smartphones, wireless keyboards, wireless mice, medical devices, hearing aids, watches, music players, etc. Inductive charging uses the principle of electromagnetic induction. An electric current is passed through the charging station to create a magnetic field that allows the device to be sensed and charged. This type is usually used for medium-sized portable devices such as tablets, music players and kitchen appliances. The last one is resonant charging. This principle is used to charge wirelessly by setting two copper coils to the same electromagnetic frequency. However, this type is usually used for devices that consume a lot of power such as computers, electric cars, vacuum cleaners, etc.

The advantages offered by wireless charging technology should not be underestimated. First of all, it is very convenient in use. Different devices tend to have different charging ports; Android usually uses USB-C port, while Apple has its own port. If you have multiple different devices, you need to prepare many different data cables. But if you use wireless charging, you can finish charging as long as it is compatible with the wireless charging standard of the charging head. Second, the durability of the interface is better. Wired charging requires frequent plugging and unplugging of the charging cable, which will speed up the wear and tear of the cable, but wireless charging avoids such problems, making it more durable. Lastly, wireless charging does not have the problem of exposed interfaces, so it reduces the possibility of oxidation and corrosion.


Wireless charging technology is now widely used in everyday life, from small smartphones to electric cars and medical devices. With the rapid development of this technology, we will soon be able to transmit electricity through pure air within a few meters. Wireless charging is expected to expand the market and increase mobility in the future. It is estimated that the global wireless charging market will exceed $30 billion by 2026. It provides maximum convenience for users while ensuring safe charging.
