Safety
The inflator’s automatic shut-off helps prevent overinflation by stopping when the preset pressure is reached. The LED work light improves visibility during roadside repairs, and using your vehicle’s 12V socket avoids handling high-voltage batteries. The product also includes a one year warranty for added protection.
Problem Solving
This unit solves common problems like low or flat tires when you are away from service stations, topping up pressure before long drives, and keeping bikes or small trailers ready. It can re-inflate a flat to a safe driving pressure and maintain target PSI without constant monitoring, though its modest hose length and compact pump mean it works best for passenger vehicles and light-duty needs.
Key Benefits
- Automatic shut-off so you do not overinflate and can multitask while it works
- 150 PSI capacity covers cars, bikes and many small trailers
- Compact size and carrying case make it easy to store and transport

FAQ
Is It Right For My Vehicle?
The FORTEM inflator reaches up to 150 PSI, so it handles passenger cars, bikes and many small trailers comfortably. You power it from a 12V outlet, which makes it convenient for roadside use, but the short 1.5 foot hose and compact motor mean it is not designed for heavy commercial or frequent high-volume jobs.
Keep that in mind if you run large truck tires or need continuous industrial use.
How Do I Use It Safely And Effectively?
Plug the unit into your vehicle 12V outlet, attach the hose snugly to the tire valve, set the target pressure and start the pump; the automatic shut-off will stop inflation when the preset PSI is reached so you do not have to watch it constantly. Use the built-in LED if you are working at night and position the inflator where the cord and hose are not stressed.
For a totally flat tire expect longer fill times and give the pump short breaks during extended runs to avoid overheating.
What If The Pressure Reading Seems Wrong Or The Unit Stops Working?
Calibration can drift over long use, so check the digital reading against a separate handheld gauge if you suspect an error; you can still inflate to a safe pressure using that gauge. If the pump won’t run, confirm the 12V connection and the vehicle fuse or cigarette-lighter socket are providing power and allow the unit to cool if it has been running continuously.
If problems persist, reach out to Fortem support and reference the 1 Year Warranty for repair or replacement options.
