Someone suggested something like this but from what I can tell its not a voltage regulator, it seems like it just filters noise. 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. I'm hoping for something I can place inline. 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. The Mac mini when running in my tests idles around 1A but underload around 9A. 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) I have it working but the computer seems to stutter and lag with the varying voltage of the battery instead of a constant 12v. I am in the process of converting a Mac mini to run directly on 12v and ditching the AC-DC power supply.
