The reason why there is no multi-protocol wireless fast charging is mainly due to the following reasons:
< br >
The working principle of wireless charging technology is to use electromagnetic induction to achieve energy conversion, and to achieve energy transfer through the coupling between the charging base (transmitting end) and the receiving device (receiving end). Therefore, the implementation of wireless charging technology requires the communication protocol between the charging base and the receiving device to ensure the stability and security of the charging process. Because different wireless charging protocols may work differently and communicate differently, supporting multiple wireless charging protocols at the same time may lead to problems such as reduced charging efficiency and increased device costs.

At present, there are a variety of wireless charging protocols on the market, such as Qi, Powermat, A4WP, etc. These protocols differ in terms of charging power, charging efficiency, and security. Therefore, if multiple protocols are supported at the same time, compatibility problems may occur, resulting in a decrease in the matching degree between the charging base and the powered device, and normal charging cannot be achieved.

The popularization of wireless charging technology requires the support and cooperation of upstream and downstream of the industrial chain. If the wireless charging protocol is too dispersed, it may lead to the fragmentation of the industrial chain, which is not conducive to the development of wireless charging technology.

Although there are a variety of wireless charging protocols on the market at present, with the continuous progress of technology and the continuous maturity of the industry, wireless charging technology may gradually standardize and unify to achieve multi-protocol compatibility. At the same time, some wireless charging manufacturers are also actively promoting the standardization and compatibility of wireless charging technology, such as the Qi standard has become one of the universal wireless charging standards.
The reason why there is no multi-protocol wireless fast charge is because wireless charging technology itself is a standardized technology, and wireless chargers from different manufacturers follow the same standards, so there is no need for private protocols to achieve fast charging like wired fast charge. Of course, the power and compatibility of wireless chargers from different manufacturers may vary, but these are differences within the standard range, and will not be completely incompatible like wired fast charge.
Because each one has a different protocol and uses a different chip, you can't support them all
