Review: Perfect for powering a mini USB powered dash cam, hardwired into vehicle. - I hadn’t realized 12v wasn’t useable by a mini USB powered device. I wanted to hard wire the dash cam into my vehicle instead of using the cigarette lighter plug. I wired it to 12v at the car’s fuse box but then the camera wouldn’t turn on. Only then did I learn USB uses 5v. This DC/DC converter takes your 12v supply and outputs 5v, exactly what the camera is looking for. Great product, works perfectly.
Review: Works for my dash cam. - I used this for a hard wire dash cam on 2 of my vehicles. Haven’t had an issue and it’s been almost a year. Provides enough power for the camera. They’re built well and great for the price.

### ⭐⭐⭐⭐⭐ Works for my dash cam.
*by J***. on July 3, 2025*

I used this for a hard wire dash cam on 2 of my vehicles. Haven’t had an issue and it’s been almost a year. Provides enough power for the camera. They’re built well and great for the price.

### ⭐⭐⭐⭐⭐ It really works. I'm using about 700mA, and it barely warms.
*by D***. on January 27, 2025*

I got this little guy for to run a 5V Netgear unmanaged switch from a 12V source. It does its job, is sealed more or less, protected from moisture. So far it has worked great. The switch draws up to 700mA from the 5V output. A small piece of double-stick tape holds it on the scope mount.
