Just about every company that makes barbecue gas grills makes portable gas barbecue grills now. Most are of basic design similar to their bigger siblings while using smaller canisters of propane either 14.1 or 16.4 oz. The disposable canisters are available in drug and grocery stores as these smaller grills gain popularity.
One of the best known and loved names in grilling is Weber. Weber has a line of portable gas grills that range from a single burner camping version to dual burner tailgate worthy models. Make sure you check out the type of gas that some of the models take as the older Baby Q designs only took 16.4 oz and you had to rig it so that it would take the 14.1 canisters. Weber has corrected this oversight in the newer models. The prices range from around 60 US dollars for the Go-Anywhere model to close to 175 for the Q 200. The quality of the Webers, they operate easily and have plenty of room to cook for 2 to 4 people at a time.
Most of the major manufacturers in gas grills or kitchen appliances now have portable gas barbecue grills on the market. Cuisinart, Coleman, Thermos, Char-Broil all have portable models that work well in camping or tailgating situations. They all can be compared very easily if you want to go with a name brand that is of tried and true design.
One of the portable gas barbecue grills that is innovative is the Holland Companion portable gas grill. The Holland is the Cadillac of the portable gas grill models. It uses indirect, radiant heat that brings the heat up from the front and the back of the grill box. There is a pan in the middle that catches drippings making flare-ups nonexistent. The Holland is one of those grills that take a little getting used to because it uses indirect heat instead of direct heat like a regular grill either gas or charcoal. Cooking on a Holland grills and bakes so you are not going to get the grill marks on your steaks like you would on other grills. Items that take longer such as larger birds or roasts work well on the Holland Companion. At about 250 US dollars to start (40 for a cover, other accessories available), you are getting into a serious investment but the Holland is well worth it.
If you camp or tailgate and want to have the ability to cook onsite any of the available portable gas barbecue grills are well worth a look. The portability and outstanding performance make some of these models a good portable and a good home unit. Make sure you get a model that is big enough for the amount of people you are cooking for and the type of situations you will be in.
