#14737 NEW IN BOX Increased speed and air volume, to get you back on the road faster: Fully inflate 2 car tires or top up car tires 8 times, thanks to enhancements that deliver 45.4% higher inflation performance on a full charge. High-precision cylinder block supports pressures up to 150 psi: The high-precision die-cast cylinder block made from alloy materials inflates from 0 psi to 150 psi in just 20 seconds*, making it suitable for use with shock absorbers on mountain bikes, as well as high-pressure tires on road bikes. Highly accurate air pressure sensors means no more fiddling with manual pumps: Digitally controlled air-pressure sensors improve inflation accuracy to ±1 psi*, putting an end to back-and-forth tire pressure checking as you inflate.
