Adjusting the temperature of propane smokers takes only the turn of a knob. That's just one of the attractions of these smokers. They are also convenient, having no wood or charcoal to mess with, and many have easy push-button ignition of the flame. However, these smokers can have problems in windy conditions.
The bullet style vertical smokers are similar to vertical electric and charcoal water smokers. The lower section of the gas smoker has a built-in gas burner. A woodchip box is mounted over the burner to provide smoke to the smoke chamber. There is a water pan above the chip box, which can be used full of water, empty, or with sand.
Brinkmann produces a model called the Smoke'n Grill, which is an inexpensive way to join the world of propane smoking. With double racks, it's claimed to have a 50 pound capacity. My Brinkmann Gourmet electric smoker claims the same, but it just ain't so. Space must be allowed for heat and smoke to circulate. Realistically, expect to be able to smoke no more than 30 pounds at a time.
Bradley has added a portable smoker to their line of products. The automatic smoke generator is powered by either 4 AA batteries, or it can be attached to a vehicle accessory plug with the included cable.
This lightweight smoker has four racks that will hold a lot of food. They can be adjusted on the metal frame of the the smoke chamber to accommodate different sizes of food. A folding tent-like cover goes over the frame and racks to hold in the heat and smoke.
Great for picnics, camping and tailgating, the Bradley Gas Smokers are quality cookers at an affordable price.
Recently I purchase a Char Broil 600 smoker, a rectangular, single door cabinet-type smoker. A larger version is available, the Char Broil 800 smoker, that has two doors, the lower door giving access to the combination water/wood pan that's positioned directly over the flame.
Assembly took about an hour, and required only a few tools.
So far it's been a great smoker, except that when the wind is blowing it's difficult to maintain the desired temperature. It's necessary to either place the smoker in a less windy location, or to devise some sort of windbreak to help with the temp control problem.
