Qi is the world's first wireless standard to promote wireless charging technology, the Wireless Power Consortium (WPC) has introduced the "wireless charging" standard, which has two features: convenience and versatility. First of all, different brands of products, as long as there is a Qi logo, Qi wireless charger can be used to charge. Secondly, it has overcome the technological bottlenecks of the “universality” of wireless charging. In the near future, mobile phones, cameras, computers and other products can be charged with Qi wireless chargers, which will provide possibilities for large-scale wireless charging applications.
The mainstream wireless charging technology in the market mainly uses three methods, namely electromagnetic induction, radio waves, and resonance, while Qi uses the most mainstream electromagnetic induction technology. In terms of technology applications, Chinese companies have already stood at the forefront of the wireless charging industry. It is reported that Qi's application products in China are mainly mobile phones. This is the first stage, and will be applied to different types or higher power digital products in the future.
