The MT3608 chip is used to increase DC voltage. The minimum voltage is 2V. The MT3608 board provides a minimum output of 5V DC.
What can be done with this voltage boosting chip?
Make lithium batteries output 5V, 6V, 9V, or 12V.
Convert a 4V or below into outputs of 5V, 6V, 9V, 12V, or higher.
Small module board for voltage boosting.
The MT3608 chip consumes power below 5mAh, very efficient for internal idle power. It can be connected to lithium batteries for 6V or 9V battery applications.
DC-to-DC conversion is most efficient around 200mAh.
Second most efficient ranges are 100-200mAh and 300-500mAh.

MT3608 specifications:
Maximum output current is 2A.
Recommended voltage difference between input and output is 3V for low voltages below 4V DC.
Efficiency of DC-to-DC conversion:
At 3V, 200-600mAh: 89% efficiency
Above 600mAh up to 1000mAh: efficiency drops between 87-85%
For 3.7-4.2V input: best efficiency for higher input voltages, 95% to 89% up to 1000mAh load
Input 5V to 18V constant is very efficient at around 90% max 500mAh
Input 12V to 18V efficiency improves to 92-95% max 500mAh
Input 16V to 18V has highest stable conversion efficiency at 95% between 100-500mAh
