The Airhead 12V High-Pressure Air Pump with pressure release valve produces 3 times the pressure of other 12-volt air pumps. It does a great job of getting towables, boats, and rafts nice and firm for peak performance. Adapters are provided for all popular valves. A removable pressure release valve limits the output to 1.4 psi, the perfect inflation pressure for towables. The 21" hose is heavy-duty and reinforced with PVC coils. This powerful pump draws too many amps to plug into a cigarette lighter style outlet. Hook it up to your car, truck, or boat battery with the alligator clips and 10' power cord.• Volume: 410 liters/minute• Maximum pressure: 2.5 psi• Amp Draw: 28 amps• Dimensions: 5.75"H x 7.68"L x 5.9"W | Airhead 12V High-Pressure Air Pump 5.75"H x 7.68"L x 5.9"W | The House
