Multi-purpose inflation and high pressure gear

The LIVOWALNY Tire Inflator Air Compressor Compatible is an aftermarket solution built for owners of Milwaukee 18V lithium-ion batteries who want strong output without buying an original equipment manufacturer tool. Sold as a bare tool, this portable air pump works with standard 18V slide-on battery packs including models 48-11-1820, 48-11-1822, 48-11-1840, 48-11-1850, 48-11-1852, 48-11-1860, and 48-11-1862. It combines a 25-millimeter large cylinder with an efficient brushless motor, achieving an air flow capacity of up to 30 liters per minute. In practical terms, this allows the pump to fill a standard 195/65/R15 vehicle tire in under three minutes, while reaching an impressive milwaukee inflator max PSI rating of up to 160 PSI for high-pressure bicycle tires and sports equipment.

Internally, this LIVOWALNY tire inflator milwaukee 18V compatible unit features an all-metal cylinder and metal gear configuration capable of running continuously for 20 minutes, enough to address four passenger tires consecutively. A wide digital LCD screen provides clear readouts of both your real-time tire pressure and your target shut-off setting, accompanied by a low battery warning icon. Users can cycle across four pressure scales including PSI, bar, kPa, and kg/cm², or pick from four pre-programmed inflation modes designed for cars, motorcycles, bicycles, and athletic balls. An integrated automatic shut-off system halts airflow within an accuracy margin of +/- 0.5 PSI to prevent over-pressurization, while an onboard LED work light provides continuous illumination or an SOS flashing mode for nighttime roadside emergencies.

Weighing only 0.93 kilograms, this vertical red inflator is remarkably easy to carry in a vehicle utility compartment or workshop tote. It comes packaged with four accessory nozzles suited for automotive valve stems, bicycle valves, and sporting inflatables. While it delivers excellent maximum pressure and steady output, it gives way to genuine Milwaukee M18 models when filling extra-large light truck tires that demand sustained heavy-duty airflow. For DIY homeowners, cyclists, and drivers seeking a versatile 18V inflator for milwaukee battery packs, this tool provides capable inflation performance across everyday items.

• All-metal cylinder and gear structure supporting up to 20 minutes of continuous runtime and 160 PSI maximum pressure
