The Airhead High-Pressure Air Pump inflates and deflates quickly and effectively. Peak pressure is 2.5 psi which is enough to get high-end inflatable boats, rafts, and reinforced backyard items nice and firm. You'll immediately notice how they perform better when properly inflated. A pressure release valve is included to limit pressure to 1.4 psi for preventing over-inflating towables, pool toys, and other vinyl and nylon-covered inflatable items. The accordion-style hose locks onto the pump, eliminating annoying disconnections. Four universal valve fittings fit all popular valves and lock onto the hose. You'll love the exclusive Airhead screw-on Boston Valve adapter. For added convenience, there's a carry handle and a 10' long power cord.• Volume: 460 liters/minute• Maximum pressure: 2.5 psi• Amp Draw: 6.1 amps Accordion-style hose locks onto the pump Four universal valve fittings including a screw-on Boston Valve adapter Moves 460 liters per minute with a maximum pressure of 2.5 psi | Airhead High-Pressure Air Pump, 120V
