Beware the power supply.
I recently bought a Powertech MB3806 - a 15600 mAh supply to run a new Pi4(8GB) board with Stellarmate. It purports to supply the USB -C with 3 Amps. I use it with a Pi 3B and a Pi4(4GB) with no issues. The Pi4(4) is in a sexy case with dual fans and is booting off a SSD. But I bought a sexy special case to go with the 8(8) - one with a good fan and a built-in M.2 SSD. ARGONone M.2. It’s a great case and the Pi runs beautifully on it BUT when I try to run it on the Powertech, it refuses to boot. After much backward and forward with Core Electronics, we have isolated the cause to the active cooling fan which seems to draw an unacceptable amount of power from the Pi at boot. As Core told me, the Pi will settle to run on less once its booted but it needs the whhole bag at boot.
Pity because I wanted to run this as a remote system at the scope and do the whole thing on battery. So read the specs on your powervsupply closely.
