KeenPower Cordless Tire Inflator Rechargeable 21V Handheld Air Compressor, 160 PSI, Auto Shut-Off

This portable air compressor combines cordless convenience, a clear digital gauge, and fast airflow so you can inflate car tires, bike tires, sports gear, and inflatables without guesswork. Designed for roadside use and routine vehicle maintenance, the unit offers both battery and 12V DC power options, three LED lighting modes for low-light situations, and a user-friendly LCD interface that displays live and target pressures in multiple units.

How fast and accurate is the KeenPower inflator?

The inflator produces up to 60 liters per minute and can raise a typical car tire from 24 PSI to 34 PSI in under a minute, while the digital gauge shows both current and preset values in real time. Auto shut-off stops inflation at your chosen pressure to avoid over- or under-inflation.

• Maximum pressure: 160 PSI for a wide range of tires and inflatables
• Airflow: up to 60 L/min for quick fills
• Live LCD readout and selectable units: PSI, Bar, kPa, kg/cm²
• Auto shut-off once target pressure is reached for consistent results

What power options are available for on-the-go use?

The KeenPower inflator supports a rechargeable 21V lithium battery for cordless convenience and a 12V DC input for direct power from your vehicle. Switching between battery and DC lets you adapt to long trips or emergency roadside top-ups without worrying about a dead battery.

• 21V rechargeable battery for cordless operation
• 12V DC power input for car-adapter use when the battery is low

Which inflation modes and controls make this inflator simple to use?

The unit includes four preset smart modes plus a manual mode that lets you set any pressure between 3 and 160 PSI, so beginners and experienced users alike get predictable outcomes. Large increase/decrease buttons and an intuitive LCD make choosing and fine-tuning pressures straightforward.

• 4 preset smart modes for common tasks and a manual mode for custom pressure
• Easy-to-read LCD showing preset and real-time pressure values
• Incremental buttons for precise pressure adjustment
• Auto shut-off to prevent over-inflation and simplify the process

How does the KeenPower inflator help in low-light or emergency situations?

Built-in LED lighting offers three modes—steady, strobe, and SOS—so you can illuminate the valve area or signal for help after dark. The light is positioned near the pump head for targeted illumination while you connect fittings and read the display.

• Three LED modes: steady, strobe, and SOS for visibility and signaling
