This high-volume (290 liters / minute) 12 volt portable air pump inflates and deflates towables, boats, pools, mattresses and beach toys quickly and effectively. Most pumps on the market don’t put out this kind of air volume and pressure (380 liters/min., .8 psi). The universal valve fittings fit all popular valves. For added convenience, the cigarette lighter plug is equipped with a 10 ft. long power cord. We recommend topping off towables inflated with 12 volt pumps with a few strokes of AIRHEAD’s Double Action Hand Pump or Foot Bellows Pump.
