With micro-USB cables are pretty much everywhere that you can borrow.
Because micro-USB cables vary greatly in quality. Some are unable to carry sufficient current to actually make it viable for charging. People don't know the difference which is a cause of problems and complaining on the forums. A barrel jack does away with this particular problem ...
See some of the early Pine64 threads with topics such as 'why doesn't it boot?' and 'it doesn't work': Id say that 75% of those topics stem from inadequate PSUs (people trying to power the board from a phone charger) or inadequate cables.
