If You have not tried what the other reply-post suggests (dumb brick), I have a 5V 4A dumb brick I can loan for a quick test. Seattle area. It has worked on quite a few boards here. Or purchase one from where-ever, they are really useful outside of SBCs (though they are usually 5.3V and 4.xA, so watch out with sensitive parts).

What is a dumb brick?

Sounds like a USB power supply that doesn't do any power negotiation and just gives as much current over 5V as it can handle. Those things typically top out at 2.4A so not really sure where you'd get one that could do much more.

4A, in my measurements.

It is a power supply that if intelligent negotiations fail, falls back to providing 5V (at whatever current), usually (2023) USB-C.
