Portable 12V Air Compressor — 300 PSI Tire Inflator

The thing you don't think about until your tire's flat on the side of the road.

This little compressor plugs straight into your car's cigarette lighter socket and runs off 12V, so there's no separate battery to charge or forget. It pushes up to 300 PSI (20.7 bar), which is more than enough for car and bike tires, and comes with a built-in pressure gauge so you're not guessing — you can actually see when to stop.

Comes with a set of extra nozzle attachments too, so it's not just for tires. Footballs, pool floats, inflatable toys, camping mattresses — anything that needs air, this handles it.

Compact enough to toss in the trunk and forget about, until the one day you really need it.
