When did wireless charging appear?

When did wireless charging appear? The idea of ​​wireless charging appeared back in the 19th century, when physicist Nikola Tesla was conducting research in the field of wireless energy transmission. However, technology did not allow this idea to be implemented until the 21st century.

When did wireless charging appear?

The first commercially available wireless charging was launched in 2009. This was a technology developed by Palm for their Pre and Pixi smartphones. The technology was called Touchstone and used the Qi standard (from the English word “chee”), which was developed by the Wireless Power Consortium.

Since then, wireless charging has become an increasingly common technology. Today, it is supported by most smartphones and other mobile devices, and can be found in various forms, from single device charging stands to multi-port charging stations for multiple devices at once. Wireless charging technology has become an important component of the ecosystem of mobile devices, which allows charging them without additional cables and power sources.

Various technologies are used for wireless charging, which differ in surge protection, charging speed, energy transfer efficiency, and other parameters. The main types of wireless charging include:

Inductive charging: It uses electromagnetic fields to transfer energy between the charging device and the device that needs charging. This technology is supported by most modern smartphones and other mobile devices.

Resonant charging: It uses resonant oscillations to transfer energy. This technology allows you to charge devices at a distance of up to 50 mm from the charger.

Radial charging: It uses radial waves to transfer energy. This technology is still under development and has the potential to charge devices up to 5 meters away.

In most cases, wireless charging is used to charge mobile devices such as smartphones, tablets and headphones. But it is also used in other areas, such as electric vehicles, medical equipment and workplaces for charging wireless devices.

In general, wireless charging is a convenient and efficient technology for charging mobile devices, which avoids the hassle of cables and chargers, and provides a more convenient way to charge.
