This high-volume 12 volt portable air pump inflates and deflates towables, boats, pools, mattresses and beach toys quickly. Most pumps on the market don't put out this kind of air volume and pressure. The universal valve fittings fit many popular valves including Boston valves and stem valves. For added convenience, the cigarette lighter plug is equipped with a 10 ft. long power cord. Volume is 380 liters/minute. Maximum pressure: .71 psi. Draws 11.8 amps / 145 watts. We recommend "topping off" large towables inflated with this pump with a few strokes of AIRHEAD's Double Action Hand Pump or Foot Bellows Pump.
