The construction of this device is quite impressive, in that it fits entirely inside a USB plug

The level of miniaturisation is not all that impressive, these have been around for a while:

There's no mention of using the rest of the cable as the antenna, since in my experience the above tiny adapters have an equally tiny antenna and thus poor reception.

It’s still impressive. It looks really close to the official Apple one and I wouldn’t think twice about plugging an iOS thingy into my computer with it. The only telltale might be how the coating feels (the Apple ones have a specific rubberized texture), but that wouldn’t be enough to prevent me from plugging it in.

Edit: stupid me, he probably just replaced the USB-A side of a legit Apple one. Ignore the part about the coating.

Not sure how far you were from your router but I bought one of these and it worked quite fine through walls.

I have this adapter, works well with a router two levels above.

Impressive for someone like me, whose not that close to the tech!

It says there's a microcontroller as well.

There's a microcontroller in the connector at each end of your USB Type C cables.

Well, I assume in this case, one that drives and controls the wifi independent of whatever you plugged this into.

The ones in those tiny dongles have one too.
