Add the Power Swap Auxiliary Cord™ to your Lippert Power Stance™ tongue jack to equip it with a more convenient, less hassle power source. The Power Swap is a 2-way to 7-way plug that connects your jack right to the power in your tow vehicle. No more draining the battery in your RV. And no more worrying whether or not there’s an available power supply. Simply connect the 2-way plug to your Power Stance and the 7-way plug to your tow vehicle’s adapter. This allows you to use the power in your vehicle to lower or lift your trailer. Perfect for trailers without a power source to operate your electric jack. Equipped with LED lights that shine down on your trailer’s coupler for nighttime operation, from top to bottom the Power Stance is built to add convenience to your on-road adventures — including an emergency manual crank option that allows you to raise and lower your jack, even in the event of a power failure.
