Pinebook Pro Dock Power Requirements

Actually, I was referring to the dock being poorly designed from the standpoint of getting the PineBook Pro modified to take and use more input power.  We'll get it there eventually, Smile so having an inferior dock would be sad.

The BQ24171 chip inside the PineBook Pro is configured to pull less power from the Type-C port, compared to what it is configured to pull from the barrel jack.  Unfortunately, all that is configured using SMT resistors on the PCB, which makes any modifications rather inconvenient.

Right, it should not be overly complicated as a modification, and using 3 A at 9 V from the Type-C port should be the easiest option.  All that is already on my to-do list.
