Fast charging can be said to be a configuration attribute that must be valued when buying a mobile phone at the moment. However, the protocol supported by fast charging is different. When you readily pick up a tripartite head or purchase online, it is often easy to grow up.
The USB-IF (USB Standardization Organization) finally put the new certification logo into practice. In short, Users can see the authentication of USB fast charge very clearly and clearly, and directly marked the maximum charging power, currently 25W, 27W, 45W and 65W.
In the future, on-board equipment, mobile phone charging heads, will increasingly see such a clear logo.
At the same time, USB PDPPS (USB Power Delivery Programmable Power Supply) allows a wide and fine voltage range so that the power receiving device can touch the highest voltage value to achieve the maximum charging speed.
According to the data, USB-IF announced the idea of this certification label as early as CES 2016, but unfortunately it took two years before partners began to apply.
