.....and one of these

Picked it up at my local Harbor Freight on special for $49.99 (wait for a deal day and save $30-40 on it like I did)
Used it many times. Small, light, tucks under a seat or in the spar tire well nicely, and holds a charge for long periods of time.
The compressor I got is also better than those cheapie "all in one" units that take like 5 minutes per 1 lb of tire pressure increase, and hit thermal protection mode every 15 min or so. This one works quickly and I can top off all of my tires without hitting thermal protection mode. Got it on a holiday special for like $24.99 if I'm not mistaken

I also carry around a full-sized 8 lbs ABC fire extinguisher, but you can get smaller compact ones that are better suited for cars. Mine is for sure overkill.
