Rock64 With Android TV 7.1 Won't boot using 3.5mm power barrel

[Eric82]

I can only get the Rock64 to boot with a USB A-2-A cable. If I plug in a cable to the barrel it won't boot.

I am using this for power: https://www.tronsmart.com/products/w2ptu...ll-charger
With a cable like this: https://www.amazon.ca/Duttek-3-5x1-35-Ch...ower&psc=1

Would the only reason be that the USB-A port on this charger is not providing 5V-3A? If I use this adapter should I get a USB-C to USB-A cable to make this adapter work?

Some USB charging power source only supply 2A current to the device that it recognized and by default just supply 500mA. We always advise user not using the USB charger to power Single Board Computer.
