About this item
- 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 mean 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.
- Preset tire pressures, for greater ease and peace of mind: The 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.
- Five different modes that anyone can use: Five different inflation modes—each with preset air pressure values—prevent over-inflation and deliver peace of mind.
