Well, Rock 5 is indeed a bit picky when it comes to PD negotiation…
There are some attempts to improve compatibility, and e.g. @DarkevilPT would swear that Samsung EP-TA845 will always “just work”, but the bottom line is, nothing ever beats a fixed-voltage cable for this board.
Feel free to try that Samsung charger, but if it fails (or if you, somewhat like myself, already have too many chargers as it is), a trigger cable is still the most stable solution.
