•  Voltage converter: Converts a wide range of voltages, including 12 to 3.3V; 12V to 5V; 24 to 5V; 24V to 12V.

•  Good Heat dissipation with aluminum case and internal finned heatsink.

•  DIY adjustable voltage regulated power supply.

•  Ideal for 12/24V Car Laptop power supply.

•  Car LED power supply.

•  Small power motor speed control.

•  Power supply transformers.

•  Industrial equipment buck.

•  Batteries buck, and etc.

Minor Note: Although this case features some AC power markings on the metal enclosure, rest assured that it is indeed DC to DC, and you can simply follow the suggested pin mapping on the PCB silkscreen.

Decent but...

Once I looked up the components I found it to use a xl4016e1 which is rated for 8A and not 12A but still got the job done.
