Qi standard for wireless power supply
Qi is the "wireless power supply" standard launched by Wireless Power Consortium (WPC), the world's first standardization organization to promote wireless power supply technology. It has two characteristics of convenience and universality. First of all, different brands of products, as long as there is a Qi logo, can use Qi wireless charger charging. Secondly, it has overcome the technical bottleneck of "universality" of wireless charging. In the near future, mobile phones, cameras, computers and other products can be charged with Qi wireless charger, which provides the possibility for large-scale application of wireless charging.
