FWIW, I didn’t need 10 ports when I got it, but I find it’s better to have spares than to outgrow it and have to buy a second one - learned that lesson - there’s a 6-port adapter in the bedroom that started in the living room, until I got a 7th thing to plug in, and found myself swapping cables around again... After a bit I realized this was the problem I had originally sought to escape, and the solution was a bigger unit, rather than having multiples.
Oh, and keep in mind these are not hubs - there’s no upstream connection to a computer, and the devices can’t talk to each other as they could with a hub. It’s power only. These are, in essence, power strips, that simply have 5VDC USB sockets instead of 110VAC sockets.
That last is in part why I see Apple removing the AC adapter from the box as pretty much a non-issue - the world is moving in the direction of many devices coming with a power cord that simply plugs into a USB-A port to use the 5VDC standard rather than plugging into a wall socket to get 110VAC (or 220, etc. - USB is actually more standard in some respects, in that a single plug works worldwide).
These days, nearly everything that plugs into 110VAC isn’t using that format directly, instead they’re converting it to DC and stepping it down to some much lower voltage - often 5V. You can find a lot of wall socket and power strip designs these days that include 5V USB sockets because of this (I still trust Anker and Apple adapters more than those, for now - it’s still early in this evolution).
