I carry adaptors for USB-C, micro USB, mini USB (Phillips Diamond Clean toothbrush, you are guilty of still using that...) and Lightning, and USB-C PD + USB-A charging unit.

The adaptors with a hole for putting a strap is great as I can tie it to cables so that they don't get lost (in fact 2 of my cables are 2.4A Micro-USB retractables for tidiness, to which I have tied Lightning and USB-C adaptors).

I also carry USB-C PD cables with USB-A adaptor attached to them.

There are also combination cables that have different plugs attached to them, but the ties for the plugs are often made of plastic and prone to snapping off.

Plus power banks that can do PD up to 45W.

I've also bought USB-C PD cable for Surface as well, which I have been trying out on this trip (so far, so good).
