Power adapter compatibility matrix
(Amazon seems to delete support pages for old devices one after the other. So this reference table might also become useful.)

To simplify things every device has a fixed input voltage: ~5,~6,9,12,15 or 18V. They need a power supply with the same voltage, either old or new.
The only exception from this rule is PS39WR: it is rather underpowered compared to PS57CP. (So devices which require higher current won't start with a PS39WR.)
Alternative models
These are being sold second hand and look genuine. I just couldn't find them being referenced in official documentation as of 2025. (It's possible they came with devices originally but Amazon only sold a few specific models as replacement.)
- GP92NB alternative found: GP92NA
- PS73BR alternatives: LC89KS PS59CV PS96CW RE78VS
TBD: chase down barrel connector sizes and polarities
TBD: possibly add tablets, some of which uses USB-C
