150 PSI Inflation Performance

The high-performance magnetic motor and redesigned internal structure provide an approximately 25% increase in inflation speed compared with the Xiaomi Portable Electric Air Compressor 1S.

The compressor supports pressures up to 150 PSI, making it suitable for a wide range of everyday inflation requirements, including high-pressure bicycle tyres.

Under manufacturer test conditions, a 700C road bicycle tyre can be inflated from 0 PSI to 120 PSI in approximately 86 seconds.

Digital Pressure Detection & Automatic Shut-Off

The built-in digital pressure sensor provides real-time tyre pressure readings with detection accuracy of up to ±1 PSI.

Simply set the required pressure or select an appropriate preset mode. The compressor automatically stops when the selected pressure is reached, helping reduce the risk of over-inflation.

Six Inflation Modes

The Xiaomi Mijia Portable Electric Air Compressor 2 features six preset modes for different applications:

• Manual Mode: 3-150 PSI / 0.2-10.3 bar
• Bicycle Mode: 30-65 PSI
• Motorcycle Mode: 1.8-3.0 bar
• Car Mode: 1.8-3.5 bar
• Electric Scooter Mode: 45-60 PSI
• Ball Mode: 4-16 PSI

The manual mode can also remember pressure settings for convenient repeat use.

Cordless Operation

A built-in 2000mAh rechargeable lithium-ion battery allows the compressor to operate without being connected to a vehicle power socket.

The four-grid battery indicator provides a convenient visual indication of the remaining charge.

Under specified laboratory conditions, a fully charged unit can reinflate up to 10 205/55 R16 car tyres from 2.0 bar to 2.5 bar, or fully inflate at least two tyres of the same specification from 0 bar to 2.5 bar.

Actual performance varies according to tyre size, starting pressure, temperature and operating conditions.

Quick-Connect Valve Adapter

The included quick-connect valve adapter allows fast connection to compatible tyre valves without requiring complicated installation.

Additional adapters are included for bicycles and sports equipment, providing greater flexibility for everyday use.

Compact & Portable Design

Weighing approximately 490g without accessories, the compressor is designed to be easy to carry and store.

Its compact design makes it suitable for keeping in a vehicle, rucksack, garage or home emergency kit.

The integrated storage pouch keeps the supplied accessories together when not in use.

Built-In LED Light

The integrated LED light provides additional illumination when inflating tyres in low-light conditions, making the compressor useful for roadside or nighttime tyre maintenance.
