leowin Portable Tire Inflator - Battery-Powered 150 PSI, 25 L/min Fast Inflation with Auto Shut-Off

The leowin Portable Tire Inflator is a compact, battery-powered air compressor that quickly and safely inflates car tires, motorcycles, bicycles and sports balls while automatically stopping at your preset pressure.

Built for drivers, cyclists and families who want a fast, reliable way to add air on the road or at home, this compact compressor combines a high-flow pump, multiple pressure presets, a memory function and an integrated emergency light. The unit supports four pressure units (PSI, BAR, KPA, KG/CM²) and delivers up to 150 PSI with a 25 L/min airflow for rapid inflation. It also features an easy-to-read digital display and a convenient auto shut-off to prevent over-inflation.

How quickly will the leowin inflator refill a typical car tire?

Thanks to a 25 L/min airflow and a powerful motor, the inflator restores typical passenger tires in minutes rather than tens of minutes. In real-world use, it can raise a 195/65R15 tire from about 29 PSI to 35 PSI in under two minutes, reducing wait time at the roadside.

• Maximum pressure: 150 PSI for fast, high-pressure needs.
• Airflow rate: 25 L/min to speed up inflation cycles.
• Practical example: 195/65R15 tire from 29→35 PSI in less than two minutes.
• Suitable for standard car, motorcycle and bicycle tires (see size limits).

Can I preset pressures and rely on the unit to stop at the right level?

Yes — the leowin inflator includes preset modes for common uses and an auto shut-off function. Select a mode (car, motorcycle, bike, ball) or set a precise PSI value; the compressor will shut down automatically when it reaches the target, protecting tires and inflatables from overfilling.

• Pre-calibrated modes: car (36 PSI), bike (45 PSI), motorcycle (32 PSI), ball (9 PSI).
• Memory function saves the last mode and setting for faster repeat use.
• Unit selection: PSI, BAR, KPA, KG/CM² with ±1 PSI accuracy.
• Auto shut-off prevents over-inflation once the preset is reached.

What extra features help during nighttime or emergency situations?

The inflator doubles as an emergency tool with a multi-mode LED light on top. Choose steady illumination to replace or inspect a tire in the dark, SOS to attract attention, or strobe to warn other drivers — making it useful for roadside situations after sundown.

• 3 light modes: steady flashlight, SOS signal, and strobe warning.
• Compact design fits glovebox or trunk for easy storage.
• Portable battery-driven operation avoids dependence on vehicle power.

What can I inflate with this model and what are the limits?

The leowin portable compressor is versatile for everyday inflatables: passenger car tires, motorcycles, bicycles, sports balls and pool toys. It is not designed for very wide commercial tires or wheels larger than standard sizes; avoid using it on tires wider than 245 mm or those requiring more than 50 PSI continuous pressure.

• Compatible: cars, motorcycles, bicycles, balls, pool inflatables and general inflatables.
• Not for: vehicle tires wider than 245 mm or applications consistently above 50 PSI.
• Includes multiple fittings to cover common valve types for sports equipment and bike tires.

Who is this for? The leowin Portable Tire Inflator is ideal for everyday drivers, cyclists and parents who want a compact, user-friendly compressor for quick top-ups and emergency roadside use. It also suits hobbyists who inflate sports gear or pool toys and anyone who values a fast-fill device with accurate presets, a memory function, and built-in emergency lighting for after-dark assistance.
