They may have one or more HDMI outputs for a monitor or projector, an Ethernet socket for connecting to a wired network, and even a built-in microSD or SD card reader. The more expensive hubs add extra connectivity, making the most of the features of the USB-C spec. These tend to be affordable, slimline units that differ mostly in what connections they offer, whether or not they use external power, and how well they’re built. Some also work as a way of using your existing USB Type-A devices (those with a big, square-edged USB plug) on a laptop or tablet that has only a USB Type-C socket (for the smaller, round-edged plugs). The most basic hubs focus on giving you more USB connections, so that you can plug in three or four USB devices in while using just one USB port.

As with most things, you pay more for a higher spec or extra features, so the choice comes down to working out what you need and finding the best hub to meet your requirements. USB hubs start from around £8 and go up to £60 or more.

Pick the right one, and it might change how you use your computer entirely. You can take one on the move to give you connectivity wherever you need it, or leave it plugged in on your desk with everything hooked up, giving you a whole desktop setup over just one connection. Better yet, the more sophisticated models include HDMI outputs and Ethernet ports. You can hook up your USB peripherals and hard disks, and still have a socket or two free. Plug one into a spare USB port and you’ve suddenly got three, four or more ports ready for action. A growing number of all-in-one PCs and micro desktop systems suffer from a similar deficit of ports.

Looking for an HDMI, DisplayPort or Ethernet connection? You might be lucky, or you might need an adapter. Most have room for one or two USB-C ports and, if you’re lucky, a couple of USB 3.1 or 3.2. Those super-slim, featherlight MacBooks, Chromebooks and Windows laptops look great and are easy to lug around, but there’s a price to be paid when it comes to ports and sockets.

Yes, modern laptops have stunning high-resolution screens and the processing power to run the most demanding applications, but if there’s one thing they lack, it's connectivity. The best USB hubs are perhaps the most humble of computer/laptop peripherals.
