The Vevor electric trailer jack is a heavy-duty power tongue jack designed to lift and support RV, horse, utility, and yacht trailers with up to 4,000 lbs of capacity. Built from durable carbon steel with a protective coating, it is made for long-lasting use in outdoor conditions. Its adjustable height range helps keep trailers level across different road surfaces, while the included waterproof cover adds protection from water and UV exposure. A built-in LED work light improves visibility at night, and the included hand crank allows emergency operation during a power outage.
