China's First Quickly Charge Standard Release. Dec 18, 2017

Clear! China's first quickly charge standard release, Apple "fast charge" is not fast charge! 

What is fast charging? Is there a clear standard? I did not, but now I have it. 2017-12-13 afternoon, "Tell Forum Forum 2017 Fast Charge Technology Standards and Applications Seminar" was held in Dongguan. The conference led by Tellabs developed a clear and detailed fast charge standard. From then on, Is fast charge "This issue has been conclusive.

According to the contents of the meeting, our definition of "fast charging" is as follows: 1. charge 60% of the charge within 30 minutes; 2. the current into the handset within 30 minutes after charging starts is not less than 3A. Only in line with the above conditions of the charging agreement, in the country can be called a fast charge.

However, although we know that the new iPhone in 2017 will support up to 18W of charge, both from "current of not less than 3A" (high voltage and low current charging mode for iPhone) or "half hour into 60% charge" Conditions, the new iPhone does not meet. In other words, if according to this standard point of view, iPhone's "fast charge" is not fast charge at all.

In addition to this set the standard fast charge, the conference also access to the phone side of the cable interface has been standardized.

Although the content is very complicated around, but I believe a closer look can understand. This meeting has finally established a standard fast-charge, manufacturers have time to promote the track. In fact, most of the Android machines on the market fast charge conditions are not affected, only Apple from the "support fast charge mobile phone" list.
