If you're going to buy a lousy 12-volt air compressor... don't! You'd be better off with a foot pump! Spend a little more for the quality of this air compressor and I guarantee it will be worth every penny. Most small compressors put out about as much air as a panting squirrel. This one fills an average sedan tire that is completely flat in less than 2 minutes! Far faster than any other compact tire inflator I've tested. Coupled with the long 10' power cord that plugs into your cigarette lighter and the 3' long air hose you'll be able to reach every tire. The air chuck screws on to the valve stem, freeing you up to do other things as the tire fills with air. Included are three optional tips that store neatly to the side of the unit for inflating your life raft, basketball or inflatable friend. The pump runs smoothly and is incredibly quiet, unlike other compressors that are loud and skip around all over the pavement. Maximum working pressure is 60 PSI and the gauge reads in 2 lb. increments. Our Tire Repair Kit is a perfect companion to this quality air compressor to get you out of a dire situation. Put one in each of your vehicles today.
