The reasons for the incompatibility of various fast charge protocols are as follows: 1. Different technical standards: The technical standards used by different manufacturers in the development of fast charge technology may be different, resulting in incompatible protocols.
Each manufacturer has its own unique fast charge scheme, which makes each fast charge protocol can not be common on different brands of devices. 2. Business strategy factors: Fast charging technology is one of the core competitiveness of mobile phone manufacturers, so some manufacturers may choose to develop proprietary fast charging solutions to protect their market share and brand image.
This commercial consideration has also led to incompatibility of fast charge protocols between different manufacturers. 3. Safety considerations: Fast charging technology involves factors such as battery charging and power supply safety, and each manufacturer will formulate corresponding protocols and standards according to its own technology and experimental results.
Different manufacturers may have different security requirements, which is also one of the reasons for protocol incompatibility. To sum up, the reasons for the incompatibility of fast charge protocols mainly include factors such as differences in technical standards, business strategies and security considerations. This is also why the fast charge protocol is not universal.
