From my anecdotal evidence, I've found so far only the Radxa 30W adapter can negotiate 5v5a, most others only go up to 3A, and a few rare ones to 4a, but none I can find in the US.
Even if the power adapter supplies it, without a high quality cable there's enough voltage drop to trigger the low voltage warning.
I recommend the official supply or eventually the official new PoE+ HAT for now.
