Description Based on MT3608 step-up power module solution, add micro usb output jack. USB Input voltage: 2-24V Output voltage: 5/9/12/ – 28V Efficiency: > 93% Size: 30 x 17 x 6.5mm Note: Input voltage should not exceed the maximum input voltage Peak current output current does not exceed 2A When the module output voltage can not be adjusted, always equal to the input voltage when the first 10 laps counterclockwise rotary potentiometer or more, then you can use the module properly regulate the voltage. Use mode: potentiometer face chest, counterclockwise turn boost! Test in image: 12V 0.5A = 6W
