Thanks to the latch locking system, WEBBQ water smoker can be used as a fire pit for cold weather, an adjustable barrel grill for grilling, steaming, baking, braising, roasting, 2 different heights of BBQ charcoal grills for meats, and as a smoker for smoking. Built-in thermometer, WEBBQ charcoal smoker with special bottom damper and ash collector, which is easy to control the bottom airflow to maintain a steady temperature inside the smoker, easily removes the ash cup and dumps ashes in seconds. Unlike integral barrel smoker, WEBBQ portable smoker can be easily disassembled into 4 parts that merely take a small cube in most of the car trunk.
