Xiaomi Portable Electric Air Compressor 2 Pro

The Xiaomi Portable Electric Air Compressor 2 Pro is designed to provide fast, accurate, and reliable tyre inflation for cars, motorcycles, bicycles, electric scooters, and sports equipment. A high-precision 27 mm alloy die-cast cylinder is integrated to deliver powerful airflow, allowing tyres to be re-inflated in as little as 45 seconds and fully inflated in approximately 3.5 minutes. With a maximum pressure output of 150 PSI and multiple preset inflation modes, efficient performance is ensured for everyday driving and outdoor activities.

A high-capacity lithium battery supports extended cordless use, enabling up to 16 car tyre re-inflations on a single charge. Real-time tyre pressure monitoring is provided through the built-in digital display, while automatic pressure detection ensures inflation stops once the preset level is reached. Compact dimensions and included accessories make this portable air compressor suitable for emergency situations, travel use, and routine maintenance.
