DC-DC Adjustable Boost Converter Voltage Regulator 3-35V to 3 5-35V Step Up Module Power Supply

Note: There is no reverse connection, please pay attention to see the positive and negative inputs.Performance parameters:1. Input voltage: 3?35V DC (Note: The input voltage is less than 4V, the onboard voltmeter is invalid)2. Input current: 9A (max)3. the output voltage: 3.5 ~ 35V DC (this board is the booster board, the output voltage should be >= input voltage)4. the output current: 6A (max)5. output power: 65W, (100W when the input and output voltage are greater than 20V)6. conversion efficiency: 96% (highest)7. output ripple: 40mV (TYP)8. onboard voltmeter range: 4 ~ 40V, error +-0.1V9. length x width x height = 6.75x4.15x1.4CMWide Usage:3.7V lithium battery rises 5V to do mobile power, 7.4V or 12V liter 18 to power the notebook.
