Powered by nothing more than the hard rush of high-pressure air, compressors can drive nails, sand wood, spray paint, or inflate the kids' pool.
DeWalt's Emglo has a 2-gallon tank and two built-in couplings, allowing a finish-nailing duo to build cabinets with assembly-line efficiency. A large front handle makes it easy to carry this 30-pounder, and at only 10 ½
inches tall, it's convenient to store. The tire inflator has a built-in gauge to check pressure as you fill up.
