Geekworm Jetson Nano 18650 UPS (5.1V Max. 8A Output)

Hi

I came across this 18650 UPS battery device for the jetson nano.

I have read that the barrel jack is max 4A.

But this says it can deliver 8A

Is it possible to deliver 8A through the barrel jack?

Thanks

Hi,
Nano module power budget is 5~10W, and carrier 0.5~1.25W with no peripherals attached.
Total won’t over 20W, so 5V@4A is enough supply, 8A battery pack supply will work, system will not consume that much.
