Weber's Kettle grills are iconic for a reason: they're ubiquitous, and they're great. The Pella from Spider Grills gives them a new trick: pellet grilling. Designed for 22" models, the Pella attaches to the side of the grill in seconds and detaches nearly as quickly. Its 12-pound capacity is enough for 12-hour cooks, with digital temp control that ranges from 175º to 500º. Powered by electricity, it's also weatherproof, easily portable, and takes up far less space than a second, dedicated pellet grill.
