Love the multi tool and tactical pen, that compressor is something I would love for the race track.

I like those RCA plates. Easy to solder, easy to mount. Much more durable than PCB mounted. These days, have leaned not do PCB mount connectors on things that get actual use, as the connector tends to be the first thing to break.
If you are into repairing Model-M keyboards, you may need a special thin-walled, odd-sized long socket.
The 12V compressor I have does not do so well on car tires @ 30lbs.

That Hychika inflator looks identical to Harbor Freight's "Bauer" brand, and I've been very happy with that for everything from my Silverado down to pool toys. Battery connection looks very similar to Bauer too... For kicks I'm tempted to grab something from them and see just how similar they are...

I have serious doubts about any cheap, China-sourced "anti-static" brushes actually being "anti-static."  I would be great if a YouTube content producer would test this.
