• Battery Compatibility: Stick with your existing tool ecosystem (e.g., DeWalt, Ryobi, Milwaukee) for cost-effective convenience.
• Run Time: Check how many tires a full charge can inflate. Look for models that can handle at least 4-5 car tires.

Performance Metrics: PSI and CFM

Understanding inflation performance specs ensures the tool meets your needs. PSI and CFM are the two most important numbers on the box.

PSI (Pounds per Square Inch) measures the maximum air pressure the pump can generate. For most passenger cars, you need at least 100-120 PSI capability. Light trucks and SUVs may require 150 PSI or more.

CFM (Cubic Feet per Minute) measures airflow volume. A higher CFM rating means the inflator can fill a larger space faster. This is crucial for inflating bigger tires or air mattresses quickly.

Key Takeaway: For standard cars, prioritize a high PSI (120+). For trucks, SUVs, or large volumes, prioritize a higher CFM rating for faster fill times.

Digital vs. Analog Gauges and Presets

The accuracy of the pressure gauge is vital for tire safety and longevity. Modern digital gauges offer significant advantages over old-fashioned dials.

• Digital Gauge Accuracy: Provides a precise, easy-to-read number, often within ±1% accuracy.
• Auto-Shutoff (Set-and-Forget): The most valuable feature. Set your desired PSI, and the pump stops automatically, preventing over-inflation.
• Backlit Display: Essential for reading pressure in low-light conditions, like at night or in a garage.

How to Use Your Cordless Tire Inflator Safely and Effectively

Owning a great inflator is only half the battle. Proper technique ensures safety, accuracy, and extends the life of your tool. Follow these steps and tips for optimal performance every time.
