1) DIY an output adjustable car power supply, only need access to your 12V power input, the output voltage you can (60-95V) continuously adjustable freely, but the output voltage can not be less than the input voltage.

2) Boost charger, you can use more than 12V power supply for 12V battery charging, for example, 72V battery.

3) In order to power your electronic devices, as long as the voltage regulator to your desired voltage and current does not exceed the rated current can all be working.

4) Solar battery charger for electric vehicles


1. Within one meter lead wire length not less than 1.5 square feet, if greater than 1 m length wire, bold, recommended 2.5 to 4 square feet of line is better
2. The module operates at high power, high temperature, plus time to install the fan housing, low power without adding a fan, be sure the module heat sink temperature should not exceed 80 degrees.
3. Using the input can not be reversed output can not be shorted.
4.12V battery discharge voltage can not be lower than 10.5V, Li-ion battery used in tandem (single 3.7V) discharge voltage can not be lower than 2.7V.

Other output current

option for 12V to 24V

1A, 2A, 3A, 5A, 8A ,10A, 12A, 15A(pls contact with our sales manager if need)


>Pls install according to the the label strictly,positive pole and nagative pole can’t be reversed, or the module and device might be damaged
>To assure this converter has the sufficient voltage and power pls make sure the voltage and power input is enough.
