I have a Pi 5, and a compatible power supply. (bought off Amazon, so I have no idea if it's the "official" supply. White wall-wart with a permanently connected cable to a USB-C end.)
I can power both my Pi, and my Display from it. (via display touch screen plugs into Pi USB port.)
Supply: https://www.amazon.com/gp/product/B0CQLNP9DZ
Display: https://www.amazon.com/gp/product/B0CJNHY3X3
Now, I need to run this setup in my truck, so I bought some 12v-USB 5A supplies.
https://www.amazon.com/gp/product/B0D5YHDY52
If I try powering the Pi from one of these, the Pi's led goes green for a few seconds, then goes red. Display never powers up either.
Output voltage on the one I'm testing is 5.22v while powering the Pi/Display, once the LED goes red, voltage goes up to 5.25v.
Is this an Over Voltage issue for the Pi?
(and of course, these little DC-DC boards don't have a trim pot to adjust.)
