1. Universal car laptop power supply. Input connected to 12V power supply, the output voltage can be adjusted to the notebook need work.
2. Boost charger with 12V power supply is higher than 12V battery charging, for example, 24V battery and charging current can be adjusted.
3. For electronic equipment power supply, as long as the voltage regulator to the required voltage and current does not exceed the rated current is normal.
4. DIY an output adjustable power supply, only need to enter the access 6v,12V.24V ,36V power supply or battery can be (14V-80V) free continuous adjustment, but the output voltage can not be lower than the input voltage.


1. Small volume, large power, high efficiency, stable operation.
2. After power on the automatic output function, can be opened or closed according to need.
3. Adopt advanced microprocessor control, voltage current precision adjustment, with buttons can be constant pressure constant current output.
4. Equipped with four eight, LED digital tube, can real-time display the output voltage and current. At the same time, the numerical control booster module with working status indicator light, can view real-time working condition.
