SmartPro 2.0 Digital Tire Inflator vs Viair 88P Portable Compressor

The SmartPro 2.0 is the easier tool for most people: it runs on wall power or a 12V socket, holds a set pressure and shuts off on its own, and its gauge is certified to ANSI Grade 1A within 1 PSI. The Viair 88P is the tougher, faster compressor, with 120 PSI and about 1.47 CFM against the SmartPro's 100 PSI and roughly 1.06 CFM, plus a 16-foot hose. Owners of both rate them highly; the Viair is the pick for trucks, big tires and repeated fills, and the SmartPro is the pick for garage and driveway use where a cord is handy.

• Choose the SmartPro 2.0 if you want set-and-forget inflation from a wall outlet or a car socket, with a certified digital gauge and automatic shutoff.
• Choose the Viair 88P if you need higher pressure and faster flow for truck, SUV or trailer tires and want a long hose that reaches all four wheels.
