Built to enhance your next camping adventure, the Power Swap Auxiliary Cord is compatible with your Lippert Power Stance tongue jack. This industry-first 2-way to 7-way plug powering system connects your electric jack directly to your tow vehicle so you can use your jack, even when your trailer doesnt have a power source. All you have to do is connect your 2-way plug to your Power Stance and the 7-way plug to your tow vehicles adapter. That way, the Power Swap will let you use the power in your vehicle to raise and lower your RVs trailer, and you dont have to worry about draining your campers battery supply.
