FAQ
Can It Inflate Car Tires
Yes, you can use it to inflate car tires for routine topping up and to get a limp-home pressure from a low tire. It can reach up to 150 PSI and has a built-in digital gauge and automatic shut-off to help you stop at the right pressure. For several completely flat tires or long continuous runs it will need periodic cooling, so plan short bursts and let it rest between cycles.
How Do I Use It Safely
Plug it into a 12 volt outlet and keep the engine running during longer inflations so you don’t drain the battery; the unit can draw up to 15 amps. Check the included replacement fuse before use, monitor the digital gauge while inflating, and let the compressor cool after extended operation. Avoid touching hot parts, secure the hose connection before switching on, and use the automatic shut-off to reduce the risk of overinflation.
What Else Can I Inflate
You can inflate motorcycles, bicycles, sports balls and small inflatables using the included nozzles, needles and the Presta to Schrader adapter. The 2 meter hose and the long power cord make it easier to reach all wheels, and the built-in LED light helps when you’re working in low light. It’s handy for quick jobs but less suitable for repeatedly filling very large items or multiple flat tires without breaks.
Why People Choose
You pick it because it’s compact enough to stash in your trunk yet powerful enough—up to 150 PSI and 35 L/min—to handle car and bike tires when you need it. The clear digital gauge, automatic shut-off, included adapters and built-in LED make routine checks and roadside top-ups simple and dependable.

Wrapping Up
The Motorenbau 150 PSI Tire Inflator is a practical pick if you want a small, feature rich compressor for occasional use and roadside emergencies. It delivers a useful combination of a digital pressure gauge, automatic shut off, an emergency LED light and a selection of adapters that let you handle car, motorcycle, bicycle and sports gear.
You will appreciate the portability, the 9.84 ft cord and the two meter hose for easier access to all tires, and the three year warranty adds reassurance. It is not the best choice for repeatedly inflating several completely flat tires because it needs cooldown after sustained use and it draws significant current from your vehicle, but for routine topping off and travel use it offers solid convenience and reliability.
