VIAIR 400P Portable Compressor Kit

VIAIR

One inflator covers truck tires, car tires, and bike tires at a high enough max PSI for any road bike

  • 150 PSI maximum pressure
  • 33% duty cycle at 20 minutes continuous run
  • IP54 dust and water resistance rating
  • Direct-drive gearless motor
  • Included accessory kit covers multiple valve types

Pros

  • One inflator covers truck tires, car tires, and bike tires at a high enough max PSI for any road bike
  • Overbuilt motor means it will never stra in trying to hit 100-plus PSI on a road tire
  • Durable enough to justify owning one inflator instead of separate car and bike pumps

Cons

  • Significant overkill and expense if bike tires are the only intended use
  • Bulkier case than a garage would need for bike-only duty
  • 26-amp draw is unnecessary for the small air volume a bike tire needs
