VIAIR EVC31 PRO wireless tire inflator — rechargeable 150 PSI, dual power with digital auto shutoff

The VIAIR EVC31 PRO is a compact, rechargeable wireless tire inflator that delivers up to 150 PSI with an auto shut-off digital gauge for quick, consistent inflation on the go.

Compact yet powerful, the EVC31 PRO combines three built-in lithium-ion batteries with an 11-foot 12V backup cable so you can inflate tires anywhere—without being tethered to your vehicle, or with your vehicle’s accessory port as a fallback. Its digital LED display lets you preset the target pressure and the unit will stop automatically when that pressure is reached. The slim housing and 30‑inch hose are purposefully designed to fit in glove compartments, emergency kits, or trunks while providing the reach and output to handle passenger cars, SUVs, light trucks, motorcycles, bikes, and common inflatables.

How fast and powerful is the EVC31 PRO?

The EVC31 PRO produces up to 150 PSI and is engineered to move air quickly so routine tire top-offs are fast. Typical passenger car tires from 25 to 35 PSI can be refilled in about one minute using the internal batteries, making it practical for roadside use or quick pre-trip checks.

• Maximum output: up to 150 PSI for high-pressure needs.
• Battery capacity: three 2500 mAh lithium-ion cells for cordless operation.
• Speed example: ~25–35 PSI car tire refill in approximately one minute.

What safety and convenience features ensure correct inflation?

Digital pressure control and an automatic shut-off prevent over-inflation by stopping the compressor once the preset PSI is reached. The bright LED display shows real-time pressure readings so you can verify values as you inflate, and the included 30-inch hose keeps you comfortable while working upright.

• Preset PSI via LED display for precise inflation targets.
• Auto shut-off stops the unit at the chosen pressure to protect your tires.
• 30-inch hose for easier reach and reduced bending during use.

How does the dual power system work when traveling?

The EVC31 PRO is designed for dual power: internal batteries for cordless use and an 11-foot 12V cable for backup power from your vehicle. If the internal battery is low, plug into the car’s accessory outlet to continue inflating without delay—handy for long trips or multiple inflations.

• Cordless operation for quick, portable use away from the vehicle.
• Included 11-foot 12V cable provides remote backup and extended reach.
• Fits gloveboxes and small storage spaces for easy transport and access.

What accessories and uses is this suited for?

Beyond vehicle tires, the EVC31 PRO works with motorcycles, e-bikes, bicycles, and many inflatables such as sports equipment and small air mattresses. Its compact footprint and versatile nozzle compatibility make it a practical addition to a commuter’s kit, a family road-trip bag, or a camping pack.

• Compatible with passenger cars, light trucks, motorcycles, e-bikes, and bicycles.
• Useful for inflatables like balls, small air mattresses, and pool toys.
• Compact enough for glovebox storage, trunk, or roadside emergency kit.

Who is this for? The VIAIR EVC31 PRO is intended for drivers and outdoor enthusiasts who want a reliable, portable inflation solution that balances power and convenience. It fits commuters who want fast tire top-offs before a long drive, families who need a lightweight inflator for trips and recreation, and anyone who prefers a cordless option with the security of vehicle backup power. Backed by VIAIR’s decades of compressor expertise, it’s built for routine maintenance, emergency topping-up, and everyday portability.
