If you prefer a standard dongle-style hub or something that doesn't have an integrated stand, here are a few other options I've tried and liked.
Twelve South Stego Mini USB-C Hubs for 60: This tiny USB-C hub is all you need, and it is Seriously Compact, it's a little longer but narrower than a Zippo lighter, and you'll find a 4K HDMI port, a USB-A, an 85-watt USB-C port with pass-through charging, and a headphone jack. I had trouble fitting it to an iPad protected by a case, but the Twelve South has a female USB-C to a male USB-C cable that solves this problem.
Hyper HyperDrive 6-in-1 Dongle at $ 80: It has a 60-watt USB-C port, USB-A, microSD slot, SD card slot, 3.5-mm audio and 4K 60-Hz HDMI. You can attach it to the USB-C port of your iPad mini, Air or Pro, and flush it firmly to the edge and sit firmly, or switch to a flappy, small cable. If you have a case on your iPad you need wiring, and the hyper part provides screws and screwdrivers to replace (it took me two minutes). Remember to unplug it when you're not using it, as it will slowly drain your tablet's battery.
Satechi USB-C Hybrid with SSD Enclosure $ 90: The four-port hub in Satechi is a little bigger, considering the ports you get, but there's a good reason. Pop the aluminum cover off and you'll get a slot for an M.2 SATA solid state storage drive slot. This means access to an external SSD with two USB-A jacks, a 100-watt USB-C pass-through charging port and a 4K HDMI at the same time. I didn't have an M.2 SATA drive to test, but this 1-terabyte card should work ($ 100). Just know that Satechi's hub doesn't support it NVME M.2 card.
Hyper USB-C to 2.5 Gbps Ethernet adapter for 50: Most people won't need an Ethernet port on an iPad, but you're probably stabbing your tablet into some cloud gaming. If so, you'll need the fastest speed so that your games are displayed at the highest possible quality. This simple, aluminum USB-C to Ethernet dongle provides download speeds of around 630 Mbps, which my desktop typically hits the iPad Pro.
