The Grill-2-Go is a 33 pound portable propane grill from Thermos that collapses into separate parts for easier storage. While Thermos uses the grill name, people have made the point that due to the cooking surface being a full cover this is actually a griddle, no direct contact is ever made by the grill's flames or smoke onto the food. One pound propane tanks work best, but full four pound tanks are compatible with an extra accessory and hose. There are two different cooking surfaces, one is flat that Thermos calls the griddle area, and the other a ridged surface that Thermos calls the grill.
