We know that the Honor 9X has been questioned by some because it uses 10W fast charging technology, which is not called fast charging. You should know that the fast charge has reached 125W, this 10W fast charge, the difference between the two is nearly 12.5 times.
So, what is the definition of fast charge? I think the fast charging surface is fast charging, and its positioning should be based on 5V1A as the standard, and the charging head over 5W is fast charging.
Although we traditionally believe that 10W is also generally 5V2A, we still think that it belongs to the category of fast charge. After all, it's raising the current.
In fact, fast charging should increase the fast charging capacity of the mobile phone while increasing the current and voltage, such as the current 120W of vivo, 125W of oppo and so on.
In fact, the current flash charging technology generally uses GaN materials. We know that GaN, as a third-generation semiconductor material, has great potential for fast charging, because of its small on-resistance, low loss and high energy conversion efficiency, so that mobile phones can be smoothly charged even at high temperatures, which may be the reason why most mobile phone manufacturers charger more than 100W.
In fact, the improvement of the so-called charging efficiency is also an indirect way to solve the battery problem, because the battery has not been solved to a greater extent, through this fast charging method, it is able to reduce the charging time and improve the charging speed, which is also an progress for the battery life. Now the charging speed may be lower than 30W, which is a slow charge!

10w charger is fast charge.
The real principle of fast charge is that in the fast charge state, the lithium ions in the lithium battery move at high speed and are instantly embedded into the two poles of the battery with a large current.
Fast charging has advantages and disadvantages, the advantages of fast charging speed is really fast, especially when urgent mobile phones are very convenient, the disadvantage is that the charging speed is fast, the battery is not full, and the discharge time is relatively short
Whether the 10 watt power adapter is a fast charge is mainly obtained by comparison. If it is for a 5 volt A power adapter, then 10 watts is definitely a fast charge. But now the power of fast charge is getting higher and higher, the highest has been out to 120 watts super fast charge. By comparison, 10 watts is definitely not fast. It must be slow to charge.
