I have just received my Boox Note Pro and I experienced the following:
- No way to charge when the origin power is USB-C

- I've tried three different USB-C (PD) chargers and it failed

- I've tried two different USB-C Power Banks and it failed

- The failure has been experienced with 4 different USB-C to C cables (Anker, Amazon, Aukey and no brand)

- USB-c to USB-C works fine to sync or transfer data (from my MacBook Pro). When I connected the Note Pro it woke up from sleep but did not charge

- I've tried three different USB-A to USB-C cables from several power sources and they all worked fine. The Boox got charged. One of the cables tested is with a magnetic tip.

I decided to comment even if the thread is quite old to stress the fact that the issue is not solved.
I agree with others that this drawback would have prevented me from buying (If I only had found the thread before ordering!!!)
I hope it helps.
Cheers.
