Most USB hubs will connect to an external display just fine, giving you more screen to fit your work. Things get even more complicated when you add displays to the mix. So your mileage may vary depending on the laptop you use. In addition, some may allow you to plug your laptop's power adapter into the hub but it may not charge as quickly or efficiently as it would if it were plugged directly into the laptop. In those cases, you'd either need a USB hub that plugs into the wall - enabling it to draw more power for those devices - or you'd need the device itself to plug into the wall (like a DVD drive that comes with its own power cable). Simple USB hubs, for example, draw power from the laptop itself and may not be able to provide enough juice to power-hungry peripherals like external DVD drives.

Simply put, a USB hub, or docking station, expands the number of ports on your laptop through one adapter. So what do you do when you don't have enough connections for your old peripherals, external monitors, or SD cards? Well, you could grab a dongle for that one device - USB-C to HDMI and USB-C to USB-A adapters are a dime a dozen - or you could get one docking station to rule them all. Many ultraportable laptops have done away with Ethernet and HDMI ports, while others have gone even further, eschewing old-school USB ports for newer, smaller USB-C slots. As laptops get smaller and thinner, their port selection gets more and more paltry - this can get quite frustrating for anyone working from home and wrestling toward the best setup.
