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.
In the 5 volt charger, the 10w charger is a fast charge.
The charger is the use of high-frequency power technology, the use of advanced intelligent dynamic adjustment charging technology. The power frequency machine is designed based on the traditional analog circuit principle, the internal power devices of the machine are relatively large, and there is generally less noise when the load is larger, but the model has strong resistance in the harsh grid environmental conditions.
