Portable 12 V inflator for cars and bikes

The AstroAI S1 connects to a 12 V cigarette-lighter socket and delivers up to 150 PSI. A digital screen shows real-time pressure, and the unit stops automatically once the preset value is reached. The kit includes two nozzles, a needle valve adapter, a Presta-Schrader adapter and a spare fuse.

Fits in a glovebox or boot with 9.87 ft power reach

The 9.87 ft power cord and 1.57 ft air hose reach all four wheels without moving the vehicle. No external compressor or battery pack is required; the inflator draws directly from the 12 V outlet. An integrated LED illuminates the valve area for night-time or roadside use.

Suits drivers and cyclists needing occasional

Ideal for motorists who want a compact pump for routine pressure checks and for cyclists switching between Schrader and Presta valves. Not suited for high-volume tasks such as seating tubeless tyres or inflating large air mattresses, and it requires a vehicle with a working 12 V socket.

Questions about this item

How long can the AstroAI S1 inflate continuously before it needs a cooling break?

Excessive use will slow the inflation rate; let the unit cool for at least 10 minutes before continuing.

How much current does the 12 V cigarette-lighter plug draw, and what fuse rating is required?

The vehicle cigarette-lighter fuse should be rated at 15 A; a replacement in-line fuse is included in the package.

What power source must the buyer already have in the vehicle for the S1 to operate?

A 12 V DC cigarette-lighter socket with the engine running is required to power the inflator.
