Hey all, I have assembled my car pc and put together alot of the components and I had an idea.

I have a spare battery backup (fairly small) that I don't use. It can store enough power to run my computer and desktop monitor for about 4 minutes. After looking at all the DC-DC power adapters and such, I thought there must be a way to use this.

Is there any way I could plug in this device to power my computer using a standard small ATX psu in my car? It seems possible but I am totally not sure about this.
