LIVOWALNY Portable Tire Inflator — Cordless 150PSI Air Compressor, Milwaukee 18V Compatible, Digital Gauge & Auto-Shutoff

The LIVOWALNY portable tire inflator is a cordless, Milwaukee 18V-compatible 150PSI air pump with a digital gauge, auto-shutoff presets, integrated hose and emergency lighting for fast on-the-go inflation.

Compact and built for mobility, this tool-only inflator accepts Milwaukee 18V batteries (sold separately) and delivers rapid inflation for cars, bikes, motorcycles, sports equipment and inflatables. Its metal cylinder and high-flow motor produce strong output while the HD LCD and preset options keep pressure accurate. The unit’s integrated hose and compact footprint make storage simple in a glovebox, door slot or backpack.

How quickly will it inflate a typical car tire?

The LIVOWALNY pump pushes up to 28 L/min through a sturdy 21mm metal cylinder, so a standard 195/65R15 tire reaches inflation in roughly four minutes under typical conditions. Real-world time depends on starting pressure and ambient temperature, but the high-flow design is optimized for rapid recovery from low pressure.

• Max output: 28 L/min airflow
• Metal 21mm cylinder for sustained performance
• Example: 195/65R15 filled in ~4 minutes
• Five nozzle adapters for versatile use

What pressure range and accuracy can I expect?

This inflator supports 3–150 PSI with selectable units (PSI, BAR, KPA, KG/CM²) and shows live values on an HD LCD with an error margin of ±1% or less. Choose one of five preset targets or enter a custom value, and the pump will stop automatically at the set pressure to avoid over-inflation.

• Pressure span: 3–150 PSI
• Unit options: PSI, BAR, KPA, KG/CM²
• Auto-shutoff at target pressure to protect tires
• Low-voltage alert when battery drops below 15V

Will it work without an outlet and how portable is it?

Yes — the inflator is cordless and designed to run on Milwaukee 18V lithium batteries (models listed on the spec sheet) so you don’t need mains power. The hose is built into the body to prevent lost parts, and the compact chassis fits common vehicle storage spaces and cup holders for quick access on trips.

• Tool-only: battery sold separately; compatible Milwaukee 18V models listed
• Integrated inflation hose prevents extra accessories
• Small footprint fits glovebox, door slot, cup holder
• Lightweight and suited for travel, roadside use, and camping

What emergency features are included for roadside use?

The inflator includes a triple-mode lighting system: steady white for work illumination, a red warning beam to alert passing traffic, and a flashing SOS for emergencies. A one-button switch cycles modes quickly so you can both see and be seen while tending to a flat or topping off pressure at night.

• Steady white light for repair visibility
• Red warning beam for roadside safety
• Flashing SOS mode for emergency signaling
• Single-button control for immediate access

Who is this for? The LIVOWALNY 150PSI cordless inflator is aimed at drivers, cyclists, and outdoor enthusiasts who want a compact, powerful backup for tire maintenance without relying on mains power. It suits DIYers who already use Milwaukee 18V batteries or anyone willing to buy a compatible battery for cordless convenience. If you need a fast, accurate pump with built-in lighting and a space-saving design for travel, this unit is purposely engineered to be ready when you are.
