Truck, SUV and off-road tires away from any power outlet

The Vortex S6 is a 19,200 mAh battery compressor with separate high-pressure and high-volume hoses, six preset modes reaching 160 PSI and a maker-stated ±1 psi sensor. Tire modes stop at your preset; the high-volume mode does not, and the manual says you must pause it yourself.

Published specifications

  • Manual: model Vortex S6, 3-160 PSI range, sensor accuracy ±1 psi
  • Manual: 19,200 mAh (71 Wh) battery; about 2 hours to charge at 45W PD

  • Manual: inflate/deflate -4°F to 158°F; charge 32°F to 113°F
  • Manual box: compressor, air chuck, 2 hoses, 45W charger, 1.8 m USB-C cable
  • Manual: 2-year coverage; cover page also offers 1 extra year on registration

Strengths

  • Six preset pressure ranges up to 160 PSI, with the target remembered between uses
  • Maker states a ±1 psi sensor accuracy in both the manual and the product page
  • Separate high-volume hose and a deflation mode for mattresses and floats

Caveats

  • High-volume mode has no auto-stop; the manual says you must pause it yourself
  • Cannot be used while charging, and the altitude recalibration resets at every power-off
  • The 100 percent duty-cycle claim is a listing claim; the manual states no duty cycle
