Question about DJI USB-C Charger

Hello, I have a DJI MINI 4 PRO FLY MORE COMBO Question: Is it possible to charge a DJI Two-Way Charging Hub with a DJI USB-C charger? (Should actually be possible with a USB-C - USB-C cable although nothing says DJI MINI 4) And how long does it take to charge when all 3 batteries are in the hub? Up to now, my charges usually took almost a whole night if all 3 batteries had to be charged. But this was with a normal USB charging plug (mostly from Samsung) Thanks for a quick answer.
