Input Voltage: DC 2V to 24V
Output Voltage: DC 5V-28V
Maximum Output Current: 2A
Maximum Conversion Efficiency: 93%
(Minimum) (input-output) difference voltage when input is at (2V and 50% of max-input-V), loading at (50% and 100% rated current)

Note: This item with Type C connector
This is a boost converter module, so the output voltage should be at least 2V higher than the input voltage.
When the module output voltage can not be adjusted, the output voltage is always equal to the input voltage. Please adjust the potentiometer counterclockwise 20 laps or more (Let potentiometer against your chest, counterclockwise turn boost)

Package included:
10 x MT3608 voltage regulator board
