Will a USB C hub charge my laptop while I use it?

Most USB C hubs with Power Delivery (PD) passthrough let you charge your laptop through the hub while using the other ports. Look for hubs that support at least 60W PD 100W is ideal for larger laptops like the 16 inch MacBook Pro. Keep in mind that the hub itself uses a small amount of power (typically 5 15W), so the passthrough wattage is slightly less than your original charger provides.
