The average system efficiency is between 80% to 90%. For example, when the input voltage is 12V output 5V was selected and the average current consumption of the system is about 1.8 A. the Efficiency is 90%. This means that the output power will be determined by the formula:

(Output current) × (output Voltage) = 1.8 A × 5V = 9W

Input power and will be about 10 WATTS. 1W will be introduced in the form of heat.


The input current can be calculated by the formula 10 W/12V= 0,83 A.

With these parameters, the loss of the stabilizer of adventure wynosiłyby to 13W.

System efficiency depending on the consumed current.
