The iPad Pro’s single USB Type-C port is one of my main frustrations about an otherwise truly stellar piece of technology. You get to use it for one thing at a time, be it charging, using the USB-C headphone adapter, or plugging in a range of dongles (and soon, mercifully, external hard drives). I ask: can any device be “pro” if it has just one lonely port?

Thankfully, the jack-of-all-trades nature of USB-C means that you can use USB-C hubs to get those missing ports back — and then some. Apple provides very little guidance on which hubs work the best with the 2018 iPad Pro; all the company really says is that hubs and docks should both work over the USB-C connection. None of the products I tested had a badge on the box to indicate MFi / Made for iPad certification, but they all functioned (mostly) as expected.
