Harbor Freight Tools has a 12v plug-in 250lb max air compressor with built in gauge (psi & bar), for sale for $9,95.
On Fri-Sat-Sun OCT 5,6,7 they are having a Parking lot sale and the compressor will be $5.29.
This unit fits perfectly in the air compressor well factory provided in the car. This with a bottle of Slime should give you "No worries".
I've own and have used this compressor, it's great. Don't forget the valve-core tool.
It is lot #4077 They have Slime cheap too.
