Avid Power 20V Cordless Tire Inflator with 12V DC adapter

Pros

  • Battery included
  • 12V cord as backup
  • Strong multi-outlet recommendations
  • Low price

Cons

  • Loud (89.5 dB in Reviewed)
  • Battery alone could not finish a truck tire
  • Charger is AC-only
  • Maker advises 3 minutes of cool-down per 10 minutes of use

The easiest way into cordless inflating without buying into a tool platform. It is loud and slow on big tires, but with the 12V cord it is dependable and the best value here.

VIAIR EVC88P

Pros

  • Fast on sedan and SUV tires
  • Preset pressure with auto shut-off
  • 16 ft hose reaches all four tires
  • No battery to charge

Cons

  • Clamps to the battery
  • Noisy
  • Only a 1-year warranty
  • Presta valves need an adapter

A strong pick for SUV, truck and off-road drivers who want speed and unlimited runtime. The clamp-on setup is less convenient than a cordless unit, but the performance and price are good.
