General discussion • RPI5 on 12V

Hi all

I want my rpi5 running on a 12V car battery. However, I experience a lot of problems.
Using a normal 12V to 5V converter does not work. Either it does start and then goes quite immediately into sleep modus, or (using USB tool for car cigarette plug) gives a low voltage warning, eventually going to sleep.

I bought an xy3606 based 12V 5V buck converter, but that doesn't work neither. I get low voltage warnings and after a short while the rpi shuts down. I used a tool to measure voltage and that buck converter gives 4,998V DC, which is apparently not enough.

The RPI 5 runs on a powerbank, but not long enough (only a couple of hours), but I want to keep it operating for weeks or months.


When I use/monitor the current an voltage my rpi consumes, it never exceels 0,7A.

Does anyone knows a solution that works? Or can it be programmed that the RPI does not go asleep or auto-shuts down at lower voltage? I can't imagine that it does not work on 4,99V when it does work on 5,1V.

Regards
Diederik
