The 2a fast charge is equivalent to 10w.
The charger is a charging device that adopts high-frequency power technology and uses advanced intelligent dynamic adjustment charging technology.

Charger introduction
The charger (charger) can be divided into power frequency machine and high frequency machine according to the working frequency of the design circuit. The power frequency machine is designed based on the traditional analog circuit principle, the internal power devices (such as transformers, inductors, capacitors, etc.) are larger, and there is generally less noise when the load is larger, but the model has strong resistance performance in the harsh grid environmental conditions, and the reliability and stability are stronger than the high-frequency machine.
This is equal to 10w, millet plug board line, the use of 220V power supply, but it is a 2a fast charge, is after transformer treatment, the output is 5V, so its power is equal to 2ax5V=10w.
