The Airhead 12-volt High Pressure Electric Air Pump far exceeds the work of ordinary pumps. Use it to fully inflate towables, boats, and rafts for peak performance. This air pump includes adaptors for popular valves. A removable pressure release valve limits the output to 1.4 psi, the perfect inflation pressure for towables. The 21-inch hose is heavy duty and reinforced with PVC coils. This powerful 12-volt pump for towables is too powerful for a cigarette outlet, but works great when hooked up to your car, truck, or boat battery. It comes with alligator clips connected to a 10-foot power cord. The overall volume is 410 liters per minute, the maximum pressure is 2.5 psi, and it draws 28 amps/340 watts.
