A propane grill is a type of outdoor cooking appliance that uses propane gas as its fuel source. It typically features a cooking surface made of metal grates, where food is placed for grilling. Propane grills are popular for their convenience, as they heat up quickly and allow for precise temperature control. These grills come in various sizes and designs, making them suitable for different outdoor spaces. Many models include additional features like side burners, storage cabinets, and built-in thermometers. Propane is stored in portable tanks, which can be easily replaced or refilled when empty.
