Xiaomi Portable Electric Air Compressor 1S

The Xiaomi Portable Electric Air Compressor 1S offers fast and precise tire inflation with a powerful and compact design. It features internal lithium batteries and five inflation modes, including a Type-C port for added convenience. This model delivers increased speed and air volume, allowing you to fully inflate two car tires or top up eight car tires on a single charge. Compared to the Mi Portable Electric Air Compressor, it boasts 45.4% higher inflation performance.

With an air flow rate of 15L/min, the 1S outperforms the Mi Portable Electric Air Compressor’s 7L/min. It can re-inflate tires up to eight times, an improvement over the previous model’s five and a half times capability. The high-precision die-cast cylinder block, made from alloy materials, supports pressures up to 150 psi and inflates from 0 psi to 150 psi in just 20 seconds, making it suitable for mountain bike shock absorbers and high-pressure road bike tires.

Upgraded chips ensure expert performance with highly accurate air-pressure sensors, providing inflation accuracy within ±1 psi. The compressor features preset tire pressures and automatically stops inflating when the desired pressure is reached, remembering your settings for convenience. It includes five different inflation modes: Manual Mode, Car Mode, Ball Mode, Motorcycle Mode, and Bicycle Mode, each with preset values and adjustable ranges to prevent over-inflation.

The device’s internal lithium batteries eliminate the need for an external power source and cumbersome cables. Weighing only 480g, it is designed for portability, fitting easily into bags or cars. The Type-C port supports universal charging options, including USB adapters, in-car charging, and power banks. An in-built LED light enhances usability in low-light conditions and features an SOS flashing function for emergencies.

Additional features include a storage bag, Needle Valve Adapter, and Presta Valve Adapter. The air hose on/off switch prevents accidental power-on due to vibration, and the flexible hose allows inflation from multiple angles. The device has separate internal compartments for optimal heat dissipation and safety, having passed eight rigorous durability tests such as overpressure protection and free-fall drop testing.

Performance metrics indicate that the compressor can inflate various items efficiently: at 6 psi, it inflates approximately 63 balls in about 28 seconds per ball, and at 50 psi, it inflates around 9 car tires in approximately 2 minutes and 9 seconds per tire.
