Hi,
I am in the process of converting a Mac mini to run directly on 12v and ditching the AC-DC power supply. I have it working but the computer seems to stutter and lag with the varying voltage of the battery instead of a constant 12v. In my search I have found Buck-Boosters but they seem to be not so clean and generate a lot of heat? I would think this is something fairly common to get battery voltage (10v-16v) and output it to a constant 12v? But in this case the amperage is fairly high (12.5A max but usually not more than 9A in my tests)
The Mac mini when running in my tests idles around 1A but underload around 9A. It would not boot using a 10A power supply, but it will boot on a battery since it can get the 12.5A it asks for to boot. I'm hoping for something I can place inline.
I found this which seems to be a nice solution but only 10A and worried it may not allow the extra needed to pass for boot.

Someone suggested something like this but from what I can tell its not a voltage regulator, it seems like it just filters noise.

I have only made a few simple circuits in my time, so I apologize if my terminology or references aren't that good.
Thank you!
