Note：

Efficiency is related to input and output voltage, current, and voltage difference.

Output current adjustment: Set the multimeter or ammeter to the 20A or 10A current position, adjust the voltage of the power supply to 5A, turn the constant current potentiometer counterclockwise for about 10 turns, adjust the current to the minimum, use the multimeter to short-circuit the output, and then adjust the potentiometer clockwise to adjust the current to the desired current value.
