The maximum output current: 2A.
The input voltage: 2 V to 24 V.
The maximum output voltage: 28V.
Efficiency: (Minimum) (input-output) difference voltage when input is at (2 V and 50% of max-input-V), loading at (50% and 100 full rated current).
Product Size: 36 x 17 x 14 mm/1.44 x 0.68 x 0.56 in(L*W*H)
package include: 5pcs MT3608 DC-DC Step Up Power Apply Module

Warm Prompt:
This is a step-up converter. Only used to raise voltage, not to lower voltage. so the output voltage should be higher than the input voltage.
Please turn the potentiometer clockwise by more than 10 turns before test.
Cannot select the maximum value of voltage and current as the output at the same time. When the output voltage is increased, the output current is reduced accordingly.
Do not use without load or light load (less than 10% of output power) or connect too much things on one module.
The input voltage should not exceed the maximum input voltage.
The peak current output current no more than TV university.
