Outlet diameter 29 mm (1-1/8 inches), width approximately 81mm, wire 1 m, voltage 12V, current 3.8A, flow rate approximately 1100 GPH under no water head and normal environmental working conditions. At a water head of 1 foot, the flow rate of a 12V battery at a current consumption of 4A is approximately 810 GPH. At a water head of 8 feet, the flow rate is approximately 585 GPH at 4.1A current consumption.Suitable for 1-1/8 inch outlets, the hose is very flexible and can make tight turns in small spaces. It is easy to lead the water pipe from the bottom of the cabin through the inner wall to the sink.
