Portable outdoor cookers commonly use charcoal, propane (LPG), and wood pellets. Product listings in the results refer specifically to charcoal, propane/LPG, and wood‑pellet power sources.
Most prep tables and carts are made from stainless steel — many listings explicitly specify 304 stainless steel for countertops and frames. Other items are listed more generically as steel or metal.
Cooking surfaces range from very small tabletop grates (about 5–7 sq in) up to several hundred square inches — examples in the listings include 147 sq in and 440 sq in. Some products provide specific dimensions, such as a 23" concave comal or a 12" × 12" pizza stone.
