Look for "pico PSU" for your 12V power supply needs. Like this one: http://www.mini-box.com/picoPSU-160-XT
Also available on Amazon ... Also from alternative sellers. That is how I power standard mini-itx systems since AsRock discontinued their mini-itx DC line two years ago. With this power supply you can power up just about anything from car battery. You could also just get true sinus inverter and power low power computer + network switch + decent access point from ordinary power outlet. If you go the power inverter route - always get the true sinus type, otherwise you will fry your switching PSUs in computer/laptop/etc. Tomas On Thu, May 23, 2019, 01:53 Chuck Hast <[email protected]> wrote: > Ahh, field day, yes I can see now exactly what you are looking for.
