The ASI300 Air Station Inflator is designed to be used in and around the home or shop using its 120 volt cord or in most vehicles with a standard 12 volt socket using its 12 volt adaptor cord. As with any battery operated item, its performance will vary directly with the battery's state of charge. Naturally, the higher the current drawn by the inflator, the more the battery power will be decreased. Campbell Hausfield, Air Express, and Craftsman make up the competitive landscape. The key competitive advantage of the B&D unit is the built-in pressure gauge that will automatically shut off when a predetermined air pressure is reached.
Black and Decker has a Air Inflator that will work for you.
