Hi
On this subject, low power warning, I use the DC-DC buck
converter somewhat like the one shown, and have found that using
it with the screw connections I got the low voltage warning. I
removed those, and soldered right to the board, and the warnings
have gone away.
I use my pi running off the buck converter while connected to my
desktop power supply, or from a 12V battery during remote away
from AC availability.

N5XMT: I have used different power supplies. I was told
about the USB-C cable and I got what I thought was a really
nice one but the problem persists. I never thought of a
difference between a charging cable and a data cable. The
only thing that I run from my USB is a $5 soundcard that
does CAT control for my uBITX. I sometimes have a? USB soft
keyboard and USB mouse plugged in
Larry: Thank you I will go look for Anker
Max: I first got the problem with the official RPI4 power
supply that came with it. I bought another official one and
experienced the same problem. That eventually led me to drop
$20 on a USB-C cable that apparently doesn't do the job
either.?
Thanks for all of the help and pointing me in the right
direction.?
