About this item

• 【EASIER THAN EXPECTED】AstroAI's tyre inflator automatically detects tyre pressure when connected, use the "M" button to set the required pressure unit (PSI, kPa, BAR, KG/CM), then press the "+" and "-" buttons to set the target pressure(up to 100PSI, make sure the target air pressure is greater than the tyre's required air pressure) then press the start button to FREE your hands; When the preset pressure is reached, the car tyre pump will voluntarily shut off, no worry about over-inflation.
