I'm not saying that a USB adapter wouldn't be useful, but for your specific use case (which is pretty rare: using an external keyboard and mouse with your laptop) you shouldn't need an adapter at all. You should be able to connect to both through Bluetooth.

Did I miss the news about charging devices over bluetooth?

You don't need to charge your keyboard and mouse from your computer; I'm assuming you have a USB-A power brick from your phone, tablet, etc. already that you can use to charge your stuff.

So, yet another device to carry around that used to be part of the functionality of a laptop.

No, not really, since you'd have to carry around a USB to Lightning charging cable even if your laptop had a standard USB-A port.

If you were already carrying a 15" laptop plus full-size external keyboard plus mouse plus power brick for the laptop, a dongle is not much of a burden to add on. And many people who did that with USB-A machines tended to carry other accessories as well and end up with an external USB hub in the bag too.

I have a keyboard and mouse at my desk. I plug them into my laptop when I'm working at my desk. I don't carry them with me at all times, though, and I don't know many people who've ever done that.
