About this item

• AUTO DETECT & SHUTOFF: Preset the value you want and press the start button, the tire inflator will start inflating and show the real-time pressure, the air compressor will automatically shut off when the pressure is reached. No more worrying about inflating too much or too little.
• DUAL POWER SUPPLY: 21V rechargeable Li-Ion battery pack power and 12V Car power DC adapter make inflating more convenient. Using a 12V car power DC adapter would be a great solution when on the go, in an emergency when the battery runs out.
• FAST INFLATION & USER FRIENDLY DESIGN:The tire inflator has a built-in high-performance chip that can inflate 195/60 R14 airless tires to 35psi in 3 minutes and 215/60 R16 airless tires to 35psi in 5 minutes. The ergonomic shape makes it easy and comfortable to hold in your hand, or you can place it on the ground. While the inflator is working, you can turn on the built-in flashlight to illuminate dark workplaces.
• MULTIPLE PURPOSE: KeenPower 21V tire inflator is suitable for cars, motorcycles, bicycles, sport balls and inflatable pool toys, etc. Note: It's not suitable for large truck tires.
• MORE THAN A TIRE INFLATOR: The built-in flashlight in the air pump can freely switch between three modes: Normal mode, Strobe mode, SOS lighting mode. On the Rechargeable Inflator Lithium-ion Battery Pack there is a 9V/2A QC3.0 USB-C output port.
