I’m running a Pi 5 here, with pretty good successes. It is my intention to build it into a portable PC for radio operations (e.g., POTA, vacations).
One concern I had was regarding power when I’m away from 120V AC. I know it’s been discussed here a lot that we have to use the official Pi 28 Watt charger and such.
HOWEVER, I have a LiFePo4 + solar battery system I built. I included in it a socket with 2 USB-C PD ports rated at 30 Watts each. (I use it to charge my MacBook Pro often.)
I just booted up my Pi 5 on that port and got no warnings about low voltages at all. It just runs. I see no difference between this and the factory power adapter.
I’m not running anything on the USB ports, so the power draw isn’t that much anyway. My configuration is Pi 5 with 8 Gb, Pi OS, Pimoroni NVMe Base board with an NVMe (Sabrent) 1 TB boot drive.
I’ll report back if I encounter any problems, but so far so good.
The socket I put in my LiFePo4 box is this one from Amazon ($20.99):
