[aprssig] DC Power Pole to USB for Pi 4 computers

Another option, perhaps at the other end of the spectrum, is to use a
powered USB 3.0 hub with a "fast charging" port.  I use one from RSHtech
that takes 12v in (so, suitable for running from a 12v battery), and has
a 2.4 amp port along with 4 USB 3.0 ports.  Each is individually
switched, so I use the charging port switch to turn on/off the Pi, and
the individual ports to control what peripherals are enabled.  Even
though the charging port is only spec'd at 2.4 amps, the system has had
no trouble driving a 4gb Raspberry Pi 4B to control my telescope.  The
Pi is not overclocked, however.

The hub uses a regular 5.5mm jack for power, but that was easy to adapt
to power poles.
