Cardos AA406 is a portable air compressor with an LCD display, designed for tyre inflation on cars, motorcycles and bicycles, as well as for inflating sports equipment and camping gear. The compressor connects directly to the vehicle's 12V cigarette lighter socket and is therefore always available when needed.

The backlit LCD screen enables precise setting and reading of tyre pressure in bar, PSI, KPA and kg/cm². Thanks to the built-in LED lamp, the unit also functions in the dark, and the auto-stop function automatically shuts off the compressor once the pre-set pressure is reached.

The compressor is supplied with a complete accessory kit – valve adaptors and a needle – making it suitable for everything from car tyres to balls, air mattresses and inflatable toys. See more K2 products for car care in our range.

What is the Cardos AA406 and why choose it?

Cardos AA406 is a compact 12V compressor with digital pressure control, developed for drivers who need a reliable tyre inflation tool without access to a stationary air supply. The unit combines high air capacity (35 L/min) with precision control via an LCD display and auto-stop, reducing the risk of over-inflation.

Compared with simpler analogue models, the AA406 offers a clearer interface, a longer power cable (3 m) and a built-in LED work light – features that make it practical at the roadside or in poor lighting conditions. The retractable air hose and the spare fuse included in the packaging contribute to a longer product lifespan and easier storage.
