Common Mistakes to Avoid
Buying Based on Price Alone
The cheapest option might cost you time and frustration when you need it most. Consider the total value, including reliability and performance.
Ignoring Your Vehicle Type
A small 12V inflator might struggle with large truck tires, while a heavy-duty unit might be overkill for a compact car.
Forgetting About Storage
Make sure you have a good place to store your compressor. Some models include carrying cases, others don’t.
Not Reading the Manual
Each model has specific operating instructions and safety guidelines. Five minutes of reading can prevent hours of frustration.
Skipping Regular Testing
Test your compressor monthly when you don’t need it, so you know it works when you do.
