Motorenbau Portable Tire Inflator — 12V Car Air Compressor, 150 PSI, Digital Gauge & LED Light, 9.84 ft Cord

The Motorenbau Portable Tire Inflator is a 12V DC-powered mini air compressor that quickly fills car, motorcycle, bike, and ball tires with a preset digital pressure and an automatic shut-off.

This compact, vehicle-powered air pump connects to a 12V cigarette lighter and delivers up to 150 PSI for everyday passenger tires. It combines a backlit digital display, smart preset controls, a built-in flashlight, and a long 9.84-foot (3 m) power cord so you can inflate tires at the roadside, in the garage, or at the track. Because it draws power from the vehicle rather than an internal battery, it stays lightweight and avoids extended charging cycles.

How quickly will this inflator restore a typical passenger tire?

The Motorenbau inflator is designed for fast filling of passenger vehicles, motorcycles, bicycles and sports equipment. Inflation speed depends on the starting pressure, tire size and desired PSI, but most standard car tires are recovered in just a few minutes.

• Maximum output up to 150 PSI for quick cycles on small to medium tires
• 9.84 ft (3 m) cord reaches most corners of a standard vehicle
• Auto-shutoff stops inflation once your preset pressure is reached

How do I set the target pressure and ensure accurate readings?

Use the M button to choose your preferred unit (PSI/KPA/BAR/KG/CM²) and the plus/minus controls to select the exact pressure. The LCD shows live readings so you can confirm the start pressure, and the pump will stop automatically at the preset value.

• Digital LCD provides clear numeric readouts and unit selection
• Preset function avoids constant monitoring during inflation
• Auto-stop reduces the risk of overinflation when set correctly

Can I use this inflator in low-light or roadside conditions?

Yes — the unit includes a backlit screen and an integrated flashlight to make connections and reading values easier after dark. The compact housing fits in a glove box or trunk so you can access it quickly when needed.

• Built-in LED light helps with valve access and connector alignment
• Backlit digital display for nighttime visibility
• Compact, lightweight design stores conveniently in vehicles

Are there any important operational limits or safety notes?

The compressor draws power from a 12V DC cigarette lighter and requires the vehicle to be running while operating. It is not intended for heavy-duty truck or large commercial tires, and the unit has automatic protection that pauses after 15 minutes of continuous use to prevent overheating.

• Requires a 12V DC outlet and engine running for stable power
• Not suitable for heavy-load or large truck tires
• Automatic 15-minute cutoff, then cool-down period is advised

Who is this for: Drivers who want a reliable, portable inflator for routine tire maintenance and emergency topping-up. It suits passenger car owners, motorcycle riders, cyclists and sports enthusiasts who need a lightweight, accurate, and easy-to-store air pump. If you need a vehicle-powered compressor with digital presets, an LED work light, and a long reach cord for on-the-go use, the Motorenbau Tire Inflator is built for that role.
