Features: Power-supply for your electronic equipment, you can set the output value according to your system voltage.Support 2V low voltage input, no-fear of low voltage, especially suitable for 18650 high-power booster.Large power, input current limit up to 15A, output current-4A; 3.7V input, the output power can-reach 45W, 12V input, the output power can-reach 80W.Protection mechanism, input is connected with anti-burning, input overcurrent protection, input undervoltage protection, output anti-backflow, constant voltage and constant current, can be directly connected to the battery charging.High efficiency, two-stage filtering low-ripple, reliable and stable performance.Specifications: Material: Electronic ComponentSize:Approx.31.5x80mm/1.24x3.15inchInput voltage: 2~24V.Output voltage: 3~30VPort input current: 15A maximumOutput current: the maximum is-4A (the-CC position-indicator is a current limiting potentiometer. When the current is limited, the CC-indicator lights up and enters the constant current-mode; BOOST boost structure, adjusting the limiting current can not directly short-circuit the output-terminal, but can be adjusted to the minimum counterclockwise first, and then rotated clockwise to increase the current after connecting the battery).Output power: under the input of 3.7V, the maximum is 45W; Under 12V input, the maximum power is 80W; Output-ripple: two-stage filtering, low-ripple output!Conversion efficiency: 82~95%.Input overcurrent protection: 15Afuse.Package Includes: 1x Boost Modulenote: .Please allow 1-2cm errors due to manual measurement, make sure that you do not mind before you order. .Due to the difference between different monitors, the picture may not reflect the actual color of the item.Thanks for your understandings.
