Just what I needed.
I used this step-down to hardwire in my Weather Alert radio to our RV. Works as expected.

The perfect fix
I have a 9vdc fan I wanted to connect to my 12vdc solar unit. Works great

Does precisely what it's supposed to do
This step-down module is being used to power a wifi-connected IP camera. This device is allowing me to take 12v directly from a battery/solar panel/charge controller and feed it to the camera. This bypasses the need for a 12vDC->120vAC->9vDC transformation along with the inefficiencies that would come at each conversion (or a 12v ->5v USB -> 9v conversion).Well worth the investment for a nearly seamless closed DC power system.

Doing what it was intended to do.
I used this to slow down my Lionel billboard that was way too loud and rough. It worked. I just wish I had bought one that put out less voltage.

it's 3 Amp NOT 1.7
I needed 1.5amp so 1.7 would have been fine but this 3amp is too much power then I need...I wish there was a way to speak to the seller to get the correct ones but there isn't a way
