Fast inflation, optimum performance

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.

Xiaomi Portable Electric Air Compressor 1S: 15L/min.

Mi Portable Electric Air Compressor: 7L/min.

Mi Portable Electric Air Compressor — re-inflates tires up to 5.5 times

Xiaomi Portable Electric Air Compressor 1S — re-inflates tires up to 8 times*

Inflation performance increase of 45.40%

Air flow rate increase 114%

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. Ready to ride with you.

Upgraded chips for expert performance

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.

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.

Multiple uses in different scenarios

Five different modes that anyone can use

Five 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.

• Manual Mode: Default 35psi – Adjustable Range: 3–150psi/0.2–10.3bar
• Car Mode: Default 2.5bar – Adjustable Range: 1.8–3.5bar
• Ball Mode: Default 8psi – Adjustable Range: 4–16psi
• Motorcycle Mode: Default 2.4bar – Adjustable Range: 1.8–3.0bar
• Bicycle Mode: Default 45psi – Adjustable Range: 30–65psi

Say goodbye to wires, thanks to internal lithium batteries

Lithium batteries mean no external power source is required, and no more cumbersome power cables are needed.
