?I ended up buying a bunch of buck converters that will take 10-24V in

weather radio) that run from 9V wall warts as well as some RaspberryPis
that need a little over 5V and run everything off of a big 12V power
supply. I set the RPi converters for about 5.3V and never see the little
low voltage warnings.

It has always amazed me with the popularity among hams of the
RaspberryPi that more 12V power solutions are not out there. I loved the
MoPi2 hat, very versatile. But, unfortunately, it was discontinued. I
wish I had bought several of them at the time. It is sad that there is
nothing comparable on the market, especially with the higher power
demands of the newer Pi versions.

I'm tired of it!

The voltage drop in most or all USB cables is too much.

Hearing about all the 'high current' capability of USB C cables, I

ordered some SHORT one and USB C to micro adapters for my old PI's.

Hopefully a solution.

I have dozens of 5v wall warts and none seem to work. The wires in

normal USB cables are way too small for several amps.

No problems here with supplies provided with my Pi4's.

Ideas?
