This Porter-Cable 2-horsepower, 6-gallon pancake compressor transports easily but has plenty of capacity and power--enough to support heavy use of brad and finish nailers and moderate use of framing nailers. This is an oil-free unit, and its advanced Teflon coating doesn't require maintenance--a big plus on the convenience scale. The 120-volt universal motor starts easily in cold weather and draws only 10 amps--so you won't have to worry about tripping breakers inside residential homes--and you can use it with an extension cord. Features include a high-flow regulator, an easy-to-read air pressure gauge, automatic thermal overload protection, an industrial-style quick-connect body in the air outlet, and a long-life motor with replaceable brushes. The compressor weighs 32 pounds and has a handle built into the motor housing, so it's relatively portable. This Porter-Cable is as convenient and easy to use as any compressor out there, and it's just about ideal for brad and finish nailers that are being used inside people's homes on a regular basis. --Jonathon Tudor
