3. Protection mechanism, input is connected with anti-burning, input overcurren t protection, input undervoltage protection, output antibackflow, constant voltage and constant current, can be directly connected to the battery charging; 1. Support 2V low voltage input, no fear of low voltage, especially suitable for 18650 high power booster; 2. Large power, input current limit up to 15A, output current 4A; 3.7V inputhe output power can reach 45W, 12V input, the output power can reach 80 Input current: maximum 15A; Output current: maximum 4A (CC positioner is a potentiometer for limiting current adjustment. When the limiting current is reached, the output power is: Under 3.7V input, the maximum power is 45W; Under 12V input, the maximum power is 80W; Input voltage: 2~24V; Output voltage: 3~30V, please note that the USB port is directly connected to the output port, which is an adjustable voltage port of 3-30V, not a 5V port; Output Ripple: Double stage filtering, low ripple output! Conversion efficiency: 82-95%; Input overcurrent protection: 15A fuse; Input anti reverse protection: high-efficiency MOS type, Manufacturer: Uxsjakjsd
