iPad Air 11-inch (M3): USB-C hub port remedies

I doubt any hub out there will directly claim iOS or iPadOS support, but being a standard USB-C, most if not all hubs should support the iPad just fine.

The iPad's port is limited to 10Gbps, so any additional ports need to share that bandwidth, which means you won't get full 10Gbps on the additional ports if more than one device is actively sending or receiving data.

There a fair number of hubs like that out there. Good quality brands include Acer, Ugreen, Belkin. Some examples:

Get a hub with more ports, or a second hub, you can plug into one of the existing hub's ports.

As Apple does not directly make any hubs for the iPad, I would suggest the issue should be raised with the manufacturer of the hub you are currently using.

Allowing for an extra few unused USB-C ports beyond your current needs......how many USB-C ports do you need?

You're welcome. Hope it works for you.
