Xiaomi’s Mijia Mini Inflator is a tire pressure gauge, compressor, and air pump in one. Smart! It features a digital display and delivers precise preset pressure. Compatible with a variety of valves, the alloy die-cast cylinder can be easily pressurized to 150 psi to meet the aeration force required for car tires, road bikes, common bicycle tires, motorcycle tires, balls, and other inflatables. It’s powered by a built-in lithium battery that recharges via USB charging.
