Features: DIY one adjustable output car power suppl y , only need to input 12V, then it can output continuous adjustable voltage ; note that the output voltage cannot be lower than the input voltage. Universal car power supply for laptop; Connect input to 12V power supply, then adjust output voltage to fit your laptop. It is also a boost charger, w hich you can use with a 12V power supply to charge a higher voltage storage battery, for example a 24V battery. Power supply for yo ur electronic equipments, it can work normally as long as you adjust voltage as needed and current should not exceed the rated current. This module would be the best choice if your project has 10-18V input while system board need 24V with big power, no ne ed to debug, easily to achieve hight efficient high-power voltage boosting. Specification: Type: Non-isolation boost module Input Voltage: 12~32V DC Output Voltage: 12V~35V DC (continuous adjustable, default 19V) Maximum Output Current: 6A Maximum Input Current: 10A Maximum Output Power: 100W (natural cooling); 150W (add cooling fan) Conversion Efficiency: 94% (when input 16V, output 19V, 2.5A; for reference only) IN+: Input Positive IN-: Input Negative OUT+: Output Positive OUT-: Output Negative Operating Temperature: -40℃ to +85℃ (if ambient temperature is more than 40℃, please reduce power, or add cooling fan) Full Load Temperature Rise: 45℃ No-Load Current: Typical 25 mA Short Circuit Protection: No (please add over-current protector at input) Reverse Input Protection: No (please add diode at input) Size: Approx. 6.5 x 4.8cm/2.6 x 1.9in Weight: 62g(approx.)
