These grills rely on a small, portable (usually 5 gallon) steel tank filled with liqufied propane gas. The gas flame either cooks the food directly, or heats grilling elements that radiate the heat.

Charcoal grills burn charcoal briquets as their fuel source. As the briquets burn, they transform to embers, offering an even heating surface.

Much like the propane grills, these grills rely on a natural gas supply. The gas flame either cooks the food directly, or heats grilling elements that radiate the heat.

Electric grills use an electric heating element to radiate heat. They require an available outlet to operate, limiting their portability, but otherwise never run out of fuel.
