PORTER-CABLE Air Compressor Kit 1.5 Gallon - Portable, Quiet Power

In this review of the PORTER-CABLE Air Compressor Kit (CMB15) we look at a compact, no-frills portable compressor aimed at DIYers and light tradespeople. The single biggest reason to buy is its combination of genuine portability and usable air delivery: at just 20 lbs with a fully shrouded 1.5 gallon tank and 2.0 SCFM @ 90 psi recovery, it delivers enough run time for inflating, brad nailing, and light pneumatic tasks while staying easy to carry and store.

Key Features

• Compact 1.5 gallon tank: The small tank size keeps weight down for easy transport and fits into tight storage spaces without sacrificing basic runtime for small tools.
• 2.0 SCFM @ 90 psi: This airflow provides quick recovery so small nailers and inflators can run with fewer pauses between cycles.
• 150 psi max tank pressure: Higher max pressure stores more air in the tank so users get longer tool runtimes before the pump cycles.
• Oil-free pump: The durable, maintenance-free pump removes the need for oil changes and simplifies ownership for occasional users.
• Fully shrouded, low-noise design: The enclosed housing protects from hot or moving parts and the 79 dBA rating helps reduce jobsite noise compared with louder compressors.
• Includes 25 ft coil hose and 8-piece kit: The supplied hose and accessories make it ready to handle common inflation and air tool tasks right out of the box.

Who It's For

This compressor is well suited to homeowners, hobbyists, and light tradespeople who need a portable, easy-to-store unit for inflating tires, running brad and finish nailers, or powering small air tools. Its low weight and hand carry design make it ideal for moving between a garage and a vehicle or carrying up a ladder to a work area.

It is not intended for heavy industrial or continuous-production use; those users should look for larger tanks and higher continuous CFM ratings. Also, professionals who require extremely quiet operation or extended runtime under heavy loads will want a bigger, belt-driven compressor.
