If your USB hub equips the USB Power Delivery (PD) port, you can use it to charge your laptop computer by connecting to a PD power adapter. 
For more information on what the requirements are and about how much power this laptop docking station provides, refer to the product specifications.

MacBook and Mac Mini using the Apple Silicon chip support only one single external display over the Thunderbolt 3 ports, even when connected to a Thunderbolt 3 hub or adapter with multiple video output. Turning off the laptop display or using clamshell mode does not change this.
Using a USB-C DisplayLink-based hub or video adapter may be an option to allow more than one external display with an Apple M1-based Mac device.
Note: this limitation does not affect Intel-based Macs with Thunderbolt 3.
