I got one from Prime Cables that not only has a magnetic attachment to the computer, it has different tips so you can use it for USB Micro, C or Lightning. The cable itself has little magnets so it coils up almost automatically.

The Expanse TV show is superb. I’m halfway through the books now, and in some ways the TV show is much better, in other ways the books are better.
There’s enough subtlety and complexity that I’ve watched the entire series twice, and I wouldn’t be averse to watching it again.
