As seen on Good Eats "Right on Que". Alton Brown said: "It"s so cool!!" * Foods cook in a smoky environment that is naturally moist resulting in foods that are juicy, fall-off-the-bone tender, and simply delicious. * Keeps a 22.5" Weber Kettle cooking at 225 degrees on one load of charcoal for up to 8 hours! * Fits Weber Kettles and Smokey Mountains, Char-Broil Horizontals and Offsets, Brinkmann Vertical, Vikings, or any cooker with a flat or spherical surface with a fire vent damper less than 5" in diameter. * Everything included in kit for operation from AC power; operates from 12VDC cigarette lighter socket using optional adapter available separately.
