Can't power Jetson Xavier using powerbank that produces 12V with the help of a quick charge trigger

Hi all,

I’m trying to create a portable power source for my Jetson Xavier. I was trying to use this powerbank. Since the USB3 ports of the powerbank only produce 5V unless triggered, I had to use an Arduino to trigger 12V out of the powerbank.

The Arduino was able to trigger 12V out of the power bank but the Jetson Xavier wouldn’t turn on when I plug power into its DC barrel jack. Does anyone know why this is the case? Notably, the power bank feeds 5V into the Jetson Xavier first before the trigger cause it to feed 12V.

Any help would be appreciated. Thank you.

Are you testing on Xavier or Xavier NX? If your Jetson can power on with adapter, then it should be the capability issue of the power bank or the Arduino.
