Overview
This Servomaster cordless tire inflator is a handheld, battery-powered air pump rated to 150 PSI, built to inflate car, motorcycle and bicycle tires as well as balls, with auto shut-off at a preset pressure.
At under 7 inches long and under a pound, it's sized for the glovebox rather than the garage, trading raw output for portability. The auto-stop function and digital gauge are meant to remove the guesswork of judging pressure by feel.
- 150 PSI maximum, auto shut-off at target
- 6.9 x 3 x 2.2 inches, 0.92 pounds
- 3-mode LED light including SOS strobe
- Ships with 4 nozzle adapters and USB-C cable
Who it's for
Drivers who want a compact backup inflator to carry in the car for topping off tires or handling a roadside low-pressure situation. Not a replacement for a shop compressor when inflating a fully flat tire repeatedly.
Strengths and trade-offs
Drawn from this product's published specifications.
- Auto shut-off at target pressure
- Compact enough for a glovebox or backpack
- Digital display shows real-time pressure
- Comes with extra nozzles for balls and bikes
- Small motor means slower fill on larger tires
- Not built for repeated full-flat inflation
Performance notes
The unit is rated to take a 195/55/R15 tire from 0 to 35 PSI in about five minutes, and once a target pressure is set it shuts off on its own rather than requiring constant monitoring. Three LED modes, steady, strobe and SOS, add a night-use and emergency-signaling function beyond straight inflation.
