300L/min Digital Display Heavy Duty Tire Inflator 12V 150 PSI

How we label data. Confirmed values are read from supplied stock and from the nameplate visible in our own product images; reference values are published marketplace specifications and are shown for identification only; anything not published is withheld rather than guessed. The model code is read from the printed label on the unit; the duty cycle is not published by the listing and is withheld.

This 300L/min tire inflator is built around two cylinders and a 12V oil-less motor: enough airflow to lift a big 4×4 or light-truck tyre several PSI in seconds, and enough headroom to keep working through a full set. For anyone who has waited on a cigarette-lighter pump, a digital display tire inflator of this size is a different job entirely.

It is a genuine heavy duty tire compressor rather than a toy: a dual cylinder air compressor with finned heads, a metal base plate and thermal protection, rated at 150 PSI, which covers passenger tyres, light-truck tyres and the higher pressures vans and RVs run. Power comes from fused battery clamps rather than a socket, so the full airflow of this 150 PSI tire inflator is available without blowing an accessory fuse, and as a 12V portable air compressor it is equally at home in a boot kit or on a workshop shelf.

The control panel is the part that makes it easy to live with. Instead of watching an analogue needle you get tire pressure monitoring on a backlit digital screen with a preset setpoint: set the target, start the pump and it shuts off at pressure. Between jobs the same screen reads true tyre pressure, so the unit doubles as a digital pressure gauge.

Construction is deliberately simple to service: an oil-less direct drive compressor, a matched intake filter, a coiled air hose and a set of nozzle adapters. It works as a practical car tire inflator, a 4×4 tire inflator and a fast auto stop air pump all in one, and it packs away in a carry bag with the hose, gauge and clamps.

• Dual cylinder heads and a direct-drive motor keep the 300 L/min airflow steady under load.
• Delivers 150 PSI maximum pressure for car, SUV, light-truck and RV tyres.
• Digital display with preset setpoint and automatic shut-off to prevent over-inflation.
• Reads live pressure in PSI, BAR or kPa, doubling as a digital pressure gauge between jobs.
• Fused battery alligator clamps avoid the cigarette-lighter fuse failures of small pumps.
• Thermal over-temperature cut-off protects the motor during long inflation runs.
• Oil-less direct drive compressor needs no lubrication and can be stored in any position.
• Coiled hose, analogue gauge, nozzle adapters and a carry bag make it a complete kit.

• Motor runs but airflow is weak and tyre pressure barely rises.
• Motor becomes very hot or smells hot within a few minutes of running.
• Digital display shows an error or fails to hold the preset pressure.
• Loud knocking or rattling from a cylinder head under load.
• Hose or quick-connect coupling leaks air at the tyre valve.
• Unit trips its inline fuse or the thermal cut-off and will not restart.

• 1Park safely, let the tyres cool and read the recommended pressure from the tyre placard.
• 2Confirm the unit is the 12V version before connecting it to a 12V battery.
• 3Clip the red clamp to positive and the black clamp to negative, engine running for high-draw use.
• 4Set the target pressure on the digital display, then start the pump.
• 5Let the automatic shut-off finish, disconnect the quick-coupler and refit the valve cap.
• 6Check the analogue hose gauge against the digital reading and let the unit cool before stowing.

• Protection for this unit: Thermal over-temperature cut-off — check it against the number stamped on your old part.
• Heavy-duty tyre repair and plug kits
• Replacement coiled air hoses and quick-couplers
