Spec at 3A due to USB 3.0 950mA consideration. if not worry about plug in USB HDD, 2A should be sufficient.
About the 5.0mm/2.1mm barrel jack vs 3.5mm/1.35mm barrel jack debate, just imagine that some Arduino user plug in their 9-12V power supply to ROCK64 board and ask support team for DoA replacement. Another consideration of using 3.5mm/1.35mm jack is this allows ROCK64 board fit into Raspberry Pi case without modification.
BTW, decide on 3.5mm/1.35mm barrel jack still better than 4.0mm/1.7mm that some board vendors used.
Just search at Amazon or eBay, there is no lack of seller that carry such 3.5mm/1.35mm jack power supply or cable.
For sure that we also need to take Pinebook into consider and standardize into only one type.
