2. Input current: 9A (max) 1. Input voltage: 3-35V DC (Note: if the input voltage is less than 4V, the onboard voltage meter fail) 4. Output current: 6A (max) 3. Output voltage: 3.5-35V DC (this board is a boost board, the output voltage must be equal input voltage) 5. Output power: 75W, (when both input and output voltages are 20V, it can reach 128W), Manufacturer: Akfldms
