That's actually me you're quoting Xalius...
I wrote that text and Igor used it to demonstrate the announcement... I still have to go back and finish collating the SD / power stuff so it can go live... should be heading back that way in a day or so... had unexpected enforced 'break' due to last revenge of a tree for being turned into firewood... 
But in a nutshell, as I originally wrote above... microUSB is perfectly fine for phone charging as they are only demanding for power, and have very broad tolerances. SBCs are a different kettle of fish entirely. If you have low power configurations, you'll probably get away with it, but the rest of the time, it's a problem just eating to bite you in the bum, and when you least expect it. I'm pretty sure the pine64 now uses a barrel jack but I still need to confirm that. If for some reason you want to use a USB charger to power the rock64, there is nothing to stop you... the standard 3.5x1.35mm barrel jack leads come with a USB connector on the other end. This doesn't really solve the problem that USB chargers/power supplies aren't the best, but it does solve the problem that the microUSB connector is at best only good for 1.8A (it's maximum rating), and depending on tarnishing of the contacts, and quality of the lead used, probably less than half of that, which is not enough for reliable booting or running of the board when loaded.
