An outdoor portable collapsible outdoor convection oven including a first side plate; a second side plate opposite the first side plate; a bottom plate releasably attached to the first side plate and the second side plate without requiring the use of a separate fastener; a food shelf disposed between the top plate and the bottom plate and releasably attached to the first side plate and the second side plate without requiring the use of a separate fastener; a top plate opposite the bottom plate, wherein the top plate is rotatably and releasably attached to the first side plate and the second side plate; and a back plate rotatably and releasably attached to the first side plate and the second side plate without the use of a separate hinge device and a separate fastener.

A collapsible stove includes an expandable combustion chamber formed from nested annular rings that can collapse to about the height of a single ring and expand into a combustion chamber for burning combustible materials. Ventilation holes at the bottom of the combustion chamber provide airflow into the combustion chamber. The combustion chamber is frustoconical and narrows at the top which increases air flow into the combustion chamber via the Venturi effect. Fuel can be added and ignited in the combustion chamber and cookware containing food can be placed onto an associated top plate suspending the combustion chamber. The collapsible stove can include rotatable legs. To use the stove, the rotatable legs can be opened, allowing the nested annular rings to telescope and expand to form the combustion chamber. For carrying and storage, the nested annular rings can be collapsed and a rotatable leg can secure the rings in the collapsed configuration.

A collapsible grill. The collapsible grill includes a base. The base is defined by several walls. An interior cavity is formed by the walls. A rod is affixed to an external surface of the base and extends upward from the base. A platform is mounted onto the rod. The platform can be adjusted vertically on the rod, so that a user can set a desired distance between the platform and the base.

A collapsible, portable, and modular grill employing biomass fuel that can be prepared from two to seven components into multiple configurations for cooking and heating, and wherein all of the components are generally flat metal plates that can be packed into a single flat container that is moderately larger than the length and width of the largest flat component, and the container is high enough to fit up to seven components stacked or laid flat on top of each other.
