This is the best performing 120 volt air pump available. Peak pressure is nearly 3.0 psi, plenty of pressure to get boats, dinghy's, rafts and reinforced backyard items nice and firm. Seven universal adapters are provided to fit all valves commonly used on boats, kayaks, towables and other inflatables. The adapters lock onto the 36 inch long heavy duty reinforced hose. A Pressure Release Valve is included to limit pressure to 1.4 psi for preventing over-inflating towables. The accordion-style hose locks onto the pump, eliminating annoying disconnections. You'll love the convenience of the screw-on Boston Valve adapter, an AIRHEAD exclusive. For added convenience, there's a carry handle and a 10 ft. long power cord. It draws 7.1 amps / 917 watts. Volume is 480 liters/minute.
