Key Features

• 150 PSI high-output motor — inflates a standard car tire from 20 PSI to 35 PSI in under 4 minutes
• Cordless rechargeable operation — built-in lithium battery; 30+ minutes continuous inflation per charge
• Digital auto-stop gauge — set your target PSI; the 280A stops automatically when the tire reaches that pressure
• LED emergency light — bright beam for nighttime tire checks and roadside visibility
• Multiple nozzle adapters — Schrader (cars), Presta (bikes), ball needle (sports equipment)
• USB-C rechargeable — plug into any USB power source; 2–3 hour full charge time
• Durable housing — heat-resistant motor casing for reliable sustained operation

The Cost of Under-Inflated Tires

Driving on tires that are just 5 PSI below the recommended pressure reduces fuel economy by up to 2%, increases tire wear by 15%, and lengthens stopping distance by up to 10 feet at highway speed. The 280A makes it easy to maintain optimal pressure — a 2-minute task that saves money and keeps you safe.

Frequently Asked Questions

Q: How fast does it inflate?
A: A standard car tire (from 20 PSI to 35 PSI) takes approximately 3–4 minutes. SUV tires from low pressure take about 5 minutes.

Q: Is it suitable for heavy trucks?
A: The 280A's 150 PSI covers passenger vehicles, SUVs, and light trucks up to 44 PSI. For commercial truck tires (80+ PSI), we recommend our heavy-duty models.

Q: What if the battery runs out mid-inflation?
A: Recharge via USB-C and continue. A partial charge (15 minutes) provides enough power to finish one tire.
