Hello.
I happen to have a *bunch* of old laptop PSU, ranging from 16V to 24V and 2A to 6A. I'd like to power Single Board Computers (SBCs) with a couple of these. Universally these SBCs take in 5V either via USB or a barrel jack, and they need approx. 2-5A @ 5V, depending on connected hardware.
What is the easiest/most efficient/most reasonable way to use these old PSUs to power the little computers?
Reasons why I want to use these:
a) I happen to have them == no need to buy anything.
b) 5V/5A powerbricks are surprisingly expensive, if you're not buying them from China, and
c) Chinese 5V/5A powerbricks tends NOT to actually be rated for 5V/5A, surprisingly.
These old laptop PSU are good brands, do actually output rated power and thus would probably have no problems supplying 3~5A @ 5V.
Just that... what is the most reasonable way to approach trying to drop down 16-24V to 5V?
