Charcoal grills provide a unique smoky flavor and are cheaper than gas grills. When choosing a charcoal grill, consider the cooking space needed based on how many people will be using it. Portability is also important - look for grills with wheels and durable, lightweight materials. Features that improve convenience include built-in igniters to avoid lighter fluid, easy to access ash pans, and well-fitting lids to contain heat and reduce smoke. Stainless steel construction is most durable for withstanding weather and heat.
