Xiaomi Portable Electric Air Compressor 2
The Xiaomi Portable Electric Air Compressor 2 is a rechargeable digital tyre inflator for bicycles, electric scooters, motorcycles and cars, with an included needle adapter for sports balls. Set the required pressure, connect the hose and let the automatic stop function finish the job. Its compact, cordless design makes it easy to carry for everyday pressure checks and top-ups.
Set the pressure and inflate
The digital display shows pressure as you inflate, with sensor accuracy of ±1psi. Choose from six operating modes: bicycle, motorcycle, car, electric scooter, ball and manual. Manual mode supports 3–150psi and remembers your last pressure setting; each preset mode has its own adjustment range. Always set the pressure recommended for your tyre or equipment.
Useful adapters for tyres and sports balls
The hose has a Schrader valve connector. A quick-connect adapter helps with attachment and removal, while the included Presta adapter and needle adapter extend compatibility to suitable bicycle valves and sports balls. Check that there is enough room to reach your valve, especially on small scooter wheels.
USB-C charging and a built-in light
A 2000mAh lithium-ion battery powers the compressor without a connection to your vehicle. Recharge through USB-C using a suitable 5V/2A power supply; a full charge takes approximately three hours. A four-segment indicator shows battery level, and the built-in light helps you see the valve in low light. A charging cable is included; a mains power adapter is not.

Before you inflate
This compressor is intended for tyres and sports balls; high-volume inflatables such as air beds are unsuitable. The hose and compressor can become hot during prolonged use, so allow them to cool. Keep the unit dry: it is not waterproof.
