Easy air inflation supports pressure up to 150 psi high-precision die-cast cylinder block made from alloy materials inflates from 0psi to 150psi in just 20 seconds*, making it suitable for use with shock absorbers on mountain bikes, as well as high-pressure tires for motorcycles.
Upgraded chips for expert performanceHighly accurate air pressure sensors and digitally controlled air-pressure sensors improve inflation accuracy to ±1 psi*, putting an end to back-and-forth inspection of tire pressure as you inflate.
Preset tire pressures, for greater ease and peace of mind automatically stop at the preset valueThe 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 use
Five different inflation modes—each with preset air pressure value prevents over-inflation and delivers exact pressure with ease. This makes the Xiaomi Portable Electric Air Compressor 1S easy for anyone to use and carry as the go to tool for air inflation.
Say goodbye to wiresComes with in-built lithium batteriesLithium batteries mean no external power source is required, and no more cumbersome power cables are needed while using the inflator.
