I don't lug all of this day-to-day but keep it in a bag for hackathons, preso days, "can you fix my blah", etc. HDMI to mini + micro HDMI, HDMI to/from DVI, Display Port to HDMI (would like to find a HDMI to DP), HDMI to HDMI coupler. Cheap HDMI to USB capture lets your laptop act as a monitor for a Pi or whatever. Composite/RCA to HDMI for old console games. Of course "dongle town" of USB-C to almost everything like ethernet, DP, HDMI, VGA, USB-A, etc. (I also have Lightning and Mac/Thunderbolt 2 versions of some of those that I take to events as loaners.) A little USB power meter (USB-C, USB-A and I think micro USB but never tried that) is damn handy. I keep a little headphone case full of USB flash drives (mostly Sandisk Cruzer Fits) with different distros / installers / etc. including a couple installed Linux environments. I miss the really flat Verbatim ones. Lighting and USB-C to 1/8" headphone (and a good old pair of wired earbuds with mic). USB to 9-pin serial and even to 25-pin printer port. I keep a couple Anker cables that are USB-A to combo USB-C/microUSB/Lightning with a USB-C to USB-A adapter. Slow but they always work. Those adapters that adapt USB-C cables to fit USB-A ports can be hazardous if you end up creating a USB-A to USB-A cable.
