### ⭐⭐⭐⭐⭐ 







  
  
    Great For Stepping Down to 5V
  

*by M***7 on Reviewed in the United States on November 24, 2019*

Used this to make a trigger for a McIntosh amplifier since they use a less voltage for a trigger input to power up the unit than most other amplifiers.  This worked perfectly!

### ⭐⭐⭐⭐⭐ 







  
  
    Convert vehicle power to 5 volts for sign
  

*by P***Y on Reviewed in the United States on October 13, 2019*

Used to power LED signboard mounted to vehicle.  Converts 12 volt truck power to 5 volts for LED message board.
