The ceramic wall has a huge heat storage capacity, which can effectively absorb heat for several hours and keep the temperature between 50-800 degrees! The heavy-duty ceramic structure and egg-shaped design are also conducive to the fuel efficiency of the barbecue. The thick sides conserve heat well, and almost no charcoal and oxygen are needed to continue fueling the fire. | Winado | | Ceramic Grill 13in Round Kamado Charcoal Grill, Portable Barbecue Grill with Thermometer for Outdoor Camping Cooking | Red | Best Buy
