ROCGORLD R8 Tire Inflator 12V 150PSI Dual Screen Blue

Portable 12 V tyre inflator with dual display

The ROCGORLD R8 is a compact 12 V air compressor rated to 150 PSI. It delivers 40 L/min airflow, inflating a 215/50 R17 tyre from 26 to 35 PSI in under a minute and a 235/40 R19 tyre from 28 to 36 PSI in roughly 1.5 minutes. A dual digital LED screen shows real-time and preset pressures. The unit weighs 1.012 kg and measures 8.509 × 16.3068 × 21.4884 cm.

Check your vehicle power outlet and valve types

Verify that your vehicle provides a standard 12 V DC accessory socket capable of supplying the compressor's operating current. The kit includes a Schrader–Presta valve adapter, a needle valve and an extension nozzle, so confirm which fittings match your tyres, bicycle tubes or sports balls. The 10 ft power cord and 2 ft hose must reach all four wheels from the socket location without strain.

Replaces slower single-screen 12 V pumps

This model upgrades from basic inflators that lack a preset pressure memory, auto shut-off or dual readout. The advanced chip adds preset storage and automatic stop at the target value, removing the need to watch a single gauge. The jump is worth it if you regularly top up car, motorcycle or bicycle tyres and want faster fill times with hands-free operation.
