1. Application: 12V car battery boosted to 24V for Bluetooth amplifier, boosted to 19V for laptop power supply, etc. 3. Output current: 6A MAX. If it exceeds 5A, please strengthen heat dissipation (the greater the voltage difference, the smaller the output current) 4. Friendly reminder: This module is a boost module, and the input voltage must be lower than the output voltage. 2. Output voltage: 15-35VDC adjustable (side potentiometer adjustment) 5. Input non-polarity reverse connection protection, pay attention to the high temperature of the positive and negative poles of the power supply. The heat dissipation is not good. If the power is relatively large, please pay attention to strengthen the fan heat dissipation, Manufacturer: Ounfhtrttk
