12V Air Compressor Kit with 6L Tank, 120 PSI

12V air compressor with tank delivers fast, stable onboard air pressure for powering train air horns and handling tire or air mattress inflation on the go. The 1.6 gal (6 L) steel tank helps reduce cycling for more consistent output, while automatic 90–120 psi operation helps prevent overpressure. Built for vehicle installs, it connects directly to a 12V battery and is designed to handle vibration, heat, and changing weather.

Set up reliable onboard air without guessing at pressure levels. This 12V tank-and-compressor system is engineered for quick connections, straightforward installation, and durable daily use in trucks, SUVs, and other 12V battery vehicles. Use it to support train horn systems or keep inflation tasks covered when you’re away from a shop. Drain the tank easily via the built-in plug to manage moisture and keep the system running smoothly. Grab yours today and keep air pressure ready when you need it.
