St-Lab USB-C Multiport Adapter with PD
St-Lab USB-C Multiport Adapter with PD.

A hub solves a shortage of ports, though the number of sockets is not the only thing that matters: every device shares the bandwidth of a single port. External drives or audio interfaces are safer on a hub with its own power supply, otherwise devices drop out now and then. Check the USB generation as well, and whether the hub passes charging back to the laptop.
