Viair Every Vehicle Carry EVC31 PRO - Portable Rechargeable Inflator

Our review of the Viair Every Vehicle Carry EVC31 PRO finds it best suited to drivers who want a true portable, battery-powered tire inflator that works on everything from motorcycles and e-bikes to full-size light trucks and SUVs. The bottom line: this is a compact, powerful unit whose standout feature is a strong lithium ion power bank that delivers fast fills and a dependable automatic shut-off, so users can set a PSI and walk away without worrying about over-inflation. It is a practical choice for roadside kits and anyone who values portability and swift, accurate inflation.

Key Features

• Dual power source: The rechargeable battery plus an included 11 ft backup accessory power cable means you can inflate tires even if the internal batteries are depleted.
• Fast inflation: With three 2500mAh lithium ion batteries and a maximum of 150 PSI, the unit fills most tires from 25 to 35 PSI in about one minute, saving time on routine top-ups.
• Smart auto shut-off: The automatic shut-off stops the compressor once the preset pressure is reached, preventing over-inflation and protecting tires.
• Long reach hose: The 30 in air hose lets you inflate while standing, making it easier to access wheel valves without awkward bending.
• Compact portability: Small enough to store in a glove box or emergency kit, the EVC31 PRO is convenient for travel, sports gear, and roadside assistance.
• Dependable brand history: Backed by more than 25 years of VIAIR experience in portable compressors, the design reflects continuous testing and refinement for durability.

Who It's For

This inflator suits drivers of passenger cars, motorcycles, e-bikes, and light trucks who want a battery-powered, cordless option for regular tire maintenance and occasional roadside use. Its power and 150 PSI capability also make it a good fit for owners who need a unit that can handle larger LT truck and SUV tires without relying solely on vehicle power.

Those who require continuous, heavy commercial use or need an inflator with an integrated air tank should look elsewhere, as this is a portable compressor designed for convenience and intermittent fills rather than sustained industrial operation.

Pros & Cons

Pros

• Strong battery pack provides fast fills and can inflate multiple tires on a single charge according to users.
• Smart auto shut-off ensures accurate pressure and reduces the risk of over-inflation.
• Compact size and a 30 in hose make it easy to store and use on the go.
• Includes an accessory power cable for backup operation from a vehicle outlet.

Cons

• As a battery-powered unit, very heavy or continuous commercial use will drain the batteries faster than a mains or tank-based compressor.
