Hello.

I've bought the TNTOR 10000mAh power bank to power on my DIY tablet. It has 3 ports :

The board is the RockPro RK399. It should be powered through 12V / 3A as you can see below (you can find the full specs of the board here : https://wiki.pine64.org/wiki/ROCKPro64

What I don't understand is what cable should I use to connect the barrell connector of the board (that requires 12V / 3A minimum) to the powerbank ? And to what USB port should I connect it ? USB A / USB C or Micro USB ? As you can see all these 3 ports are 5V / 2A max input,while the board needs 12V / 3A minimum ; are these voltages compatible ? Can you point me to the right products (cable and / or converter) that I should buy to be able to turn on the board using that power bank ? thanks.
