It works

It works like it should.

I like it!

I used the module to power the 12 volt radio in our 24 volt military-conversion fire brush truck, works well so far. I had some initial concerns that the buck converter might generate some noise in the radio, but none detected, so this is a winner in our application. I will use these on the rest of our 24 volt vehicles to provide a easy way to power 12 volt radios and light bars.

Good step down conveter

A little bit smelly when open the bag.

Got juice? Now I do!

Pleasantly surprised by this nice little unit. Seems to work fine. Sealed construction makes it good for marine applications.

Quality device

It's a simple device, but it works exactly as it should. I'm only drawing about 5 amps from it but it stays stone cold. Just be careful when wiring it, as the leftmost wire is the output and the rightmost wire is the input. Seemed counterintuitive but if you follow the wiring labels on the device, you'll be safe.
