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.
The high frequency machine is based on the microprocessor (CPU chip) as the processing control center, and the complicated hardware analog circuit is burned in the microprocessor, and the operation of the UPS is controlled by the way of software program.
Therefore, the volume is greatly reduced, the weight is greatly reduced, the manufacturing cost is low, and the price is relatively low. The inverter frequency of high frequency machine is generally above 20KHZ. However, the high frequency machine has poor tolerance under harsh power grid and environmental conditions, and is more suitable for stable power grid and less dust, temperature\/humidity suitable environment.
The output current of the charging bank is 2a, and its output power is also equivalent to ten watts. In electrotechnics, there is a constant relationship between current, voltage and power, and the values between them can be calculated according to this relationship. And the way we do it is p is equal to UI. Where p is power, U is a voltage, and i is a current.
It depends on the output voltage, the general 5V2A, 10W, is not fast charge.
