High-precision cylinder block supports pressures up to 150 psiThe 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.Ready to ride with you.

Upgraded chips for expert performance

Highly accurate air pressure sensors means no more fiddling with manual pumpsDigitally controlled air-pressure sensors improve inflation accuracy to ±1 psi*, putting an end to back-and-forth tire pressure checking as you inflate.

Preset tire pressures, for greater ease and peace of mindThe Xiaomi Portable Electric Air Compressor 1S automatically stops inflating your tires when your desired pre-set pressure is reached.It also remembers your pressure values, so you don't have to set up repeatedly.

Multiple uses in different scenarios

Five different modes that anyone can useFive different inflation modes—each with preset air pressure values—prevents over-inflation and delivers peace of mind.This makes the Xiaomi Portable Electric Air Compressor 1S easy for anyone to use.
