Lasfit Signature TK1 Cordless Tire Inflator — 150PSI Portable Air Compressor, 12000mAh Battery, Digital Gauge

The LASFIT TK1 is a cordless, high-capacity portable tire inflator that delivers fast 150PSI inflation, built-in 12000mAh battery power, and intelligent auto-stop for cars, trucks, bikes and inflatables.

Lightweight yet powerful, the LASFIT TK1 combines a dual-cylinder 50LPM airflow motor and a large 12000mAh battery to handle everything from passenger tires to heavy-duty pickup and SUV wheels. It includes an accurate digital gauge, 4 preset modes plus custom profiles, and multiple valve adapters so you can tackle roadside low-pressure situations, sports equipment and off-road wheel needs without plugging into a vehicle outlet.

How quickly will the TK1 inflate my car or truck tire?

The TK1 focuses on speed using an upgraded dual-cylinder motor that produces up to 50 liters per minute. Typical mid-size tire top-ups are very fast, and larger truck tires are reachable within a few minutes depending on starting pressure and size.

• Inflates 255/55/R20 from 29PSI to 36PSI in about 45 seconds.
• Inflates 285/70/R17 from 29PSI to 36PSI in roughly 3 minutes.
• 50LPM airflow for rapid pressure recovery during emergencies.

Will the TK1 work without being plugged into a car?

Yes — the built-in 12000mAh battery makes the TK1 fully cordless so you can inflate wheels and inflatables away from the vehicle or power outlet. The battery also doubles as an emergency power bank and powers the unit's LED light for roadside visibility.

• 12000mAh battery supports many inflation cycles per charge (approx. 27 car tire top-ups).
• USB output to charge phones or accessories in emergencies.
• Integrated LED lamp for night use and roadside safety.

How accurate and easy is pressure control with the TK1?

The TK1 uses a digital pressure gauge and a smart auto-stop system to prevent overinflation and simplify use. Set the target PSI or choose a preset mode and the compressor stops automatically when the desired pressure is reached.

• Digital gauge with ±0.5PSI accuracy for consistent results.
• Four preset modes: car, motorcycle, bicycle, ball plus programmable custom mode.
• Auto shutoff when selected PSI is achieved — hands-free operation.

What types of valves and inflatables does the TK1 support?

The TK1 ships with common adapters to cover most consumer and recreational inflation tasks, from standard vehicle tires to sports gear and small equipment. It’s suitable for cars, SUVs, trucks, bikes and many outdoor toys and tools.

• Includes Schrader and Presta valve adapters plus a ball needle.
• Compatible with pickup trucks, SUVs, sedans, EVs, UTVs, ATVs, bikes and balls.
• Works for lawn equipment tires, small tractors and other inflatables.

Who is this for? The LASFIT TK1 is ideal for drivers who want a fast, cordless solution for roadside tire maintenance — especially pickup truck and SUV owners who need higher airflow and battery endurance. It also fits cyclists, motorcyclists, and anyone who wants a reliable multi-purpose inflator that doubles as a power bank and emergency light. Backed by a 2-year LASFIT AIR warranty, the TK1 suits travelers, fleet users, and weekend adventurers who need dependable, accurate inflation without a tethered compressor.
