24V to 12V 10A DC-DC Step Down Converter | 120W Heavy Duty Voltage Reducer

120W of Regulated 12V Power from Your 24V System — For Multiple Accessories & Higher Loads

When 5A isn't enough for your 24V-to-12V conversion needs, the Jason Bang Power 24V to 12V 10A Step-Down Converter doubles the output to a full 120W. That's enough to simultaneously power a dash cam, GPS navigator, phone charger, CB radio, and a small 12V LED light bar — all from your truck's 24V electrical system.

The IP67 waterproof aluminum housing means you can mount it in the engine compartment, under the chassis, or anywhere exposed to the elements. True switching topology delivers regulated 12V that won't spike or sag, protecting your sensitive 12V electronics from the voltage swings common in commercial vehicle electrical systems.

Key Features
