  • Short circuit protection:Yes.Can auto turn off.(after output short circuit,please make sure that the output is not short circuit before turn on),The short circuit protection is a remedy measure for wrong operation, Please do not deliberately short-circuited.

  • Input voltage over warning: When input voltage over than 16.5V,red LED is light.(input voltage can not higher than 18V)

  • Input Reverse Polarity Protection: wrong input voltage connection red LED will turn light,right input connection the blue LED is light.

  • Switching method: remark "ON" is turn on, the other one is turn off.(when output no-load shutdown,please press turn off key until blue LED is turn off light,it is a few seconds)

  • Wiring:No welding, with connection ports.

  • Size:65(L)*35(W)*23.5(H) mm


  • DIY an output adjustable vehicle power supply,connect the 12V input, and output could be 10-32V(adjustable by yourself), However, the output voltage can not be less than the input voltage.

  • DIY a Car laptop power supply.connected to 12V power supply, adjust the output voltage to the value that your notebook need.

  • Boost charger. You can use the 12V power supply to charge battery higher than 12V, for example, 24V battery.

  • Power supply for your electronic equipment.
