Camping pots and pans with heat exchanger

With heat exchanger

— tourist cookware equipped with a ring featuring a ribbed or wavy surface attached to the bottom of the pot. The heat exchanger captures and directs the heat from the burner straight to the walls of the cookware, preventing it from "escaping" sideways. Additionally, the accordion-like wavy structure increases the contact area with the flame. As a result, water and food heat up faster, and less gas or wood is consumed.
