The IcyBreeze 12-Volt Power Supply Cord plugs into the cigarette lighter/car charger in automobiles, planes, and boats for continuous cooling without using the rechargeable battery. This is accessory is not a charger, and is for continuous use only.
I called customer service about a problem with getting power to my cooler. They immediately suggested that it was probably the cord and offered to send me a new cord. It arrived in two days and now my Icy Breeze cooler works perfectly. Great Product!
